So I share an internet with my family; but to be honest it is only really me and my two brothers that use it...Up untill about 2 years AGO I always used to be connected to the internet modem by lead/wire. And it was great no internet disconnection or anything! But then I decided I wanted to take my PC up stairs and so got a wireless STICK. But then came the problems...When either one of my brothers decided they was going to download my internet stopped working...But both of my other brothers internets worked.
So brother 1 downloads, brother 2 STILL playing his pc great, and my pc internet connect 0! It said my connection was perfect all bars green the best it can be but my internet cuts out untill he stop his download

Anyway I fault it may be my wireless stick since it was a old one so I went out and invested in a £60.00 one...The best one I could find. This stick is supposed to have a range where I can sit in my loft or back garden and still play games download etc...But then once again still the same thing...

After 2 years of this and looking up on the internet with no one else seeming to have this problem I have just given up and hoped that you guys would have an answer, has anyone else came across such a thing? Me and my brothers love games and they are always downloading KNEW ones...I just am fed up with being in the middle of a game and BANG! You're game has been disconnected because of your download mad hungry brother, why wont you just let me slap you in the face

Be so greatful for anyone who can shead a BIT of light on the problem, once again this seems to only happen to me and no one else...

This info may help

My PC is a DELL
Windows Vista (Home Premium)
Memory(RAM) 3.00GB
System type 32-bit Operating System
Processor: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz 2.39 GHz

My internet is also fiber optic (BT) (Best availableto me)
And my wireless stick is a NETGEAR: N600 Wireless Dual Band USB Adapter (High Performance)

Hope SOMEONE can nail this for me, have pulled the rest of my hair out and can't figure this out. Background, Home network system, netgear gigabyte wireless n router WN3500?? I think, Plugged into that is a netgear 8 port gig hub, plugged into the hub are a printer, two desktops, a server, a network media tank, and a WII. Also on the wireless side are three laptops. EVERYTHING has a permanently assigned IP address with the router. The Router, hub, server, and both desktops are on 24/7 and are on UPS's. This setup has worked FLAWLESSLY for about two years, server backing up the desktops everynight and so on. For the last month, I have ONE desktop that looses connection every NIGHT. When you hover over the connection icon in the systray, it always says unidentified network, local only. Even that is a fib as it won't see anything else on the network either, and is not showing up as connected in the router. The only way to fix it is to reboot the desktop, and all is well until the next morning. There seems to be no consistant time as to when it disconnects, just sometime in the night.
Things i have tried. Replaced the internal netgear GIG card in the desktop, assumed it was failing, replaced the cat cable, tried a different port on the hub, tried the built in 10/100 port on the desktop (with and without the gig card installed) made sure the power option for the card was not set to disable to save power, released the assigned IP address and gave it a different one, uninstalled and reinstalled all drivers, also checked for updated drivers. Everything else about this machine is working perfectly. There has been no new software or hardware changes. Stumped I am, and it is only affecting this one desktop.

Any ideas??

Thanks in advance!

BobI am going toassume you have either a cable modem or dsl. Try rebooting one of those by unplugging the power from it WAIT a couple of minutes then plug in and see if it helps and also I se that you are using a hub? what for how many ports does the netgear have if it is enough for all your periphials then i would use it instead of the hub. That's what I do and I don't have near the things plugged in that you haveQuote from: gjmay12 on July 12, 2012, 05:03:25 AM

I can not seem to UNDERSTAND why NRZ-I has a DC component problem?Again, we PREFER not to HELP with HOMEWORK here. Sorry.

im working on a question and I came up with an answer, but i would just like to clarify if its correct

the question asks We sample and digitize (with PCM) a VOICE signal with fmax=4 kHz and we use nb=6 bits/sample. The digital signal must be transmitted on a channel with bandwidth Bch= 6 kHz. What is the number of bits PER signal ELEMENT (R=?) for the worst case factor c=1 ?

the answer i have is r=4bits

I used the formula
B(min) = c(N)(1/r) = c(n(sub b))(f(sub s))(1/r) = c(n(sub b))(2)(B analog)(1/r)
As I said in one of your other posts, We PREFER not to help with homework here. Sorry.

Does anyone have experience with Wifi Access Points? I need to wire for some in a warehouse 40,000 sq ft.Welcome to CH

You may need to AP (Access Points). Depends on density.
Some 4000 square feet is not so big. How many mobile devices would You u have? Does it have a high ceiling? Is it a steel structure? Is the warehouse inventory very dense? Like very big boxes. with very little open space? Is this a warehouse with a slow moving inventory? A storage rather that a staging area? Storage only areas tend to be very dense and hard no cove with one AP.

Can you make a preliminary tour? Put a wireless router in a elevated place and then walk around with a mobile device, like a tablet, ans see if you get good reception in different areasDid you mean 2 access points? Also, its 40,000 sq ft. not 4000. 10 mobile devices. 30' ceiling. I didn't see any steel. Lots of big boxes stacked all the way to the ceiling with maybe a foot clearance. It's more of a storage area.

Thanks!!40,000 feet?
Sorry, have trouble with big numbers. That's why I am broke most of the time.

Yeah, low ceiling, dense storage. It will be a chore. WI-FI does not penetrate well in a large area with high density stuff. Mostly because the low power levels used. You may want to use another TECHNOLOGY.**

What kind of data SPEEDS? Is this video surveillance? Voice only? Or just telemetry? Why can't you just wire the whole thing. Are these devices to be carried by persons?

Lew-cost wireless surveillance cameras have a range of about 200 feet if there is line of SIGHT or very low density obstructions.

** If it is voice communication, just go with commercial walkies-talkies which are VHF and have long range and good n penetration. Quote from: Geek-9pm on June 30, 2012, 07:45:26 AM

I have this PROBLEM that I have worked out. Im only checking to see if it is correct. here is the question:

What is the Nyquist sampling rate for a band-pass SIGNAL with a bandwidth of 10 kHz if the lowest frequency is 50 kHz?

Here is what I did:
I added the bandwidth and the frequency together, and multiplied them by 2, and got 120kHz as my answer.
(10kHz + 50kHz) * 2 = 12kHz

I also read that you can only double the frequency if the max frequency is known. But it is not known in this case. Please helpWe prefer not to help with HOMEWORK here. SORRY.

I have a question to anyone out there... how can i connect virtual machine to internet CONNECTION? my host is Windows 7 and my VM is XP, im using Virtual Box...There are several modes for network connections in VirtualBox; I'll describe just 2.
NAT processes all network requests from the VM and communicates them to the internet. You will not be able to access the local network except by IP Address (if even that) because it will usually be on a different subnet, network, etc.
Bridged Networking CAUSES the VM to use your network adapter directly. This allows it to communicate on the network more easily because it will appear as if your network adapter has two computers running on it. This is necessary to run the guest as a SERVER or to read files off the local network. I've had to use this to run shared files on my host PC inside the guest PC to test them.

TL;DR: Just internet access? NAT should be fine. LAN access from inside the VM? Try bridged networking.

On the VM Settings, open Network Adapters.

Using NAT (the default): Select NAT and press OK.
Using Bridged Networking: Select Bridged Adapter, and select your network adapter from the list. Then press OK

If both of these don't work, you have a different problem (such as a firewall blocking the VM.)both your suggestions didn't work I tried to unblock the Firewall but in didn't work too, do you have any idea why this happend?Sounds like a bit more is GOING on than a simple internet connection here.

What kind of network adapter do you have; what sort of connection does your host have to the internet and through what routing devices or hubs; and does your host connect through a proxy server? Some of these configurations settings may be different on the guest PC from the host.i've figured it out I actually did a device manager check and found out that the network adapter isn't detected, so I changed the virtual adapter of the VM and it works just fine now...Good to know it's fixed. I actually had that problem with one of my VMs and completely forgot about it

Hi all members,

A few days ago, I installed ITUNES in my PC, and then PURCHASED some music.
But some strange things kept happening then, some port scan ATTACK REPORTS from my Firewall popped up frequently, saying my PC seemed to be attacked by some people at this two IPs:
124.237.78.181
124.237.77.38

I googled for these IPs, and found out that they were both located in China.

I have no idea why that Chinese guys wanted to attack my PC. For what?

Could you help me please?

Thank you.

guys i just want to ask, what is an internal server? you see, i cant search a direct meaning of internal server, all I see is internal server error in google searches..can someone explain the meaning and the significance of internal server... or could this be a broader topic...I too have only dealt with "Internal Server Error" messages before myself. But depending on its use "Internal Server" can be MANY meanings depending on how a programmer wanted to use that statement for an error alert on whatever PROGRAM they wrote. If it was more defined such as Internal Server Error in regards to a specific application you might get better RESULTS. Such as Apache Internal Server Error. Which is where I have seen this before myself working with Apache servers. You're grouping the words incorrectly. It's not an error in an "internal server". It's an internal error in a server. Typically you'll see that if a web server has been misconfigured or has been sent a request it doesn't know how to handle.Quote from: Rob Pomeroy on September 25, 2012, 09:44:00 AM

I need to use some of my office computers on two different networks. Both the networks are on CABLE and provide static IP addresses.

I have gone by the tips given on another thread and put two NETWORK cards on the PCs which need these connections. Now I am able to connect only to one network at a time. Network A has to be disabled to be able to connect to Network B, and vice versa.

Is there a solution to this problem that will let me stay connected on both the networks simultaneousl? I need to use only Internet Explorer on Network A and Outlook Mail on Network B.Quote from: ganeshnag75 on JULY 14, 2012, 09:13:02 PM

My wireless has been problem free for a while, but recently (I assume) something changed on my computer to affect my wireless. I am RECEIVING very spotty SIGNALS, while our wired connection works FINE. I tried to do a system restore but that didnt help.

I have a linysys wusb600n version 2 adapter and a 2wire 2701hg-g router. I run windows 7 64 bit

Basically what happens is the connection works sometimes, but cuts out very often and at times for hours on end. I am able to access the router and the signal stays strong the entire time, so there must be some setting which is preventing it from working properly. As far as I can tell, nothing has changed. The drivers on my adapter are up to date. I am writing this post from our wired computer so if you need any other information please let me know and I can fetch it.

Thank you for reading.
I have more information for you guys, here you are:

[year+ old attachment deleted by admin]Have you tried reinstalling the usb adapter driver? ipconfig/release then ipconfig/renew IP address on cmd on each command given and see if it makes a difference. Can you run ipconfig/all on ONE of the wired or wireless computer able to connect to your 2wire router?I think the issue was just a few days of instability on their side, although that doesnt account for the wireless not working while the direct line did. It may be coincidence when i checked or just human error.

I turned everything off for about 2 minutes and then back on, and it worked for about half an hour until it died. This morning it is working fine, but I guess Ill update if anything changes.

Yes, I updated the drivers on the adapter (they were the same as what I had, but I replaced them .Alright, so it wasnt my imagination and after working for a short while the problem came back. This time the ethernet does work but the wifi does not.

I tried ipconfig /release and renew on the connected computer but had no luck.

On the wifi connection the commands pull an error saying local connection 3 media disconnect. I dont know if this is normal or not, but I figure extra information cant hurt.

So to explain the problem briefly:
The wifi sometimes works, but only for short periods and then it stops. The signal is perfect the entire time.
this entire time, the internet works through ethernet.
The ipconfig /all listed above is from the wireless computer.One last update, I have a feeling the problem is from my adapter suddenly overheating.

When the internet last cut off I took the adapter out and felt its business end, and it was pretty warm. I left it off for a while and it worked when I plugged it back in. Unplugging and re plugging it in usually do nothing, but I was sure to cool it this time.

I am contemplating breaking the outer case to allow airflow, but I'm wondering if there are any other suggestions.

Wouldn't it be easier to GET a new WiFi adapter? I assume it is USB? An internal adapter card will generally run cooler. You can get a new one for about $10.

sounds like a security setting issue to be honest I've never heard of an IP address getting blacklisted unless they are sites that have been associated with engaging in malware infection. And you could have a malware on your system as well which is telling you this. Run R-Kill then defogger then malwarebytes scan and see what you turn up.

so if they are abusing IP's then his computer must be included? or are they just messing around with changing people's IP's? always good to hear another opinion or answer. thanks gjmay

I have a Toshiba A215 with a Realtek RTL8187B wireless adapter. I just installed Ubuntu 10 on it and everything else works fine except the internet. I've LOOKED it up and it seems LIKE a lot of the solutions have me using the command line witch I'm not great with. Anyways If someone COULD just help me find the right steps to TAKE to fix this that would be great thanks. Why are you installing Ubuntu 10? It's not even SUPPORTED anymore. Try installing a more recent version of Ubuntu which has support for newer hardware. Doing a very cursory google on your card, it sounds like support might be an issue for it. I'd suggest heading to Amazon and getting a cheap USB wireless card that reviewers say works out of the box with Ubuntu, it will save you a nightmare of a hassle.Quote from: rockstar4cs on September 26, 2012, 11:49:41 AM

Hi ALL,

I have to CPU without keyboard,mouse, monitor. I want to connect to the laptop to see display on it. How can I achieve this.

ThanksWhy do this? Old monitors are available free in some places.
Please make your question better.
Do you have one monitor already and want to add the laptop as a second monitor?
What operating systems?
Do you what a console or a GUI?
In Linux the display of one computer can be the console of another computer. MEANING..I have 2 CPU and I want to check what is in it? With the help of VGA cable can i see display on laptop screen CONNECTING to CPU VGA port.No, the laptop VGA port is a OUTPUT, not an input.

What you need is a VGA to USB VIDEO Grabber
http://sewelldirect.com/VGA-to-USB-Video-Grabber.asp?gclid=CJKT_smWorECFaEJRQodOG-7lA

But the device is rather rare and costs about $330.

You should just get a monitor. Used ones are cheap or free.
Meaning..I have 2 CPUYou could use a 2 way KVM switch and thus be able to use one mouse/one keyboard/and one monitor to access both computers alternatively. Very inexpensive method.truenorthWhen he writes "I have 2 CPU" I believe he means "I have 2 computer system boxes".

This is not a CPU

I installed windows xp on my DESKTOP and it SAYS i can not connect to the internet.You need to provide a lot more information, but let's START with come basics:

1) WHY did you have to install the OS?
2) Was it a clean (fresh) install?
3) If so, did you install all drivers starting with the chipset driver?

Try to give us as much background about what is going on and about your system as you can.new hard-drive, everything seemed to install ok, and ill check to see if it has the right network drives or whatever. If you didn't install them, it doesn't. Go to the website of the computer (or motherboard) manufacturer and download and install the chipset driver. Then go to the websites of your display driver manufacturer, sound card manufacturer and ETHERNET card manufacturer (if relevant) and do the same THING. If this is a name brand computer you can just go to the website of the computer manufacturer and obtain all drivers there.

Hello all. Does anyone know what this port is or does? I get these connections when PLAYING an ONLINE game and have no idea why they are there or do.

I have tried just about everything. I have a FOSCAM IP Wireless Camera that I have a LAN IP for. I have also SET up a domain with no-ip.com that's a DNS host for my ip.

So when I go to my domain, I get sent to the LOGIN page for my router. I am trying to set up port forwarding so I can put in my domain plus :80 at the end and forward it to the LAN ip of my camera. Basically so I can view my camera online. I've sep up a port forward in my router (I think correctly) but it still directs to the router login page when I type :80 at the end.

I've used this tool: http://www.yougetsignal.com/tools/open-ports/ to try figure out if my port 80 is open but it is not. I have set an INBOUND rule in my advanced settings in windows firewall (Windows 7), but still nothing. When I go to command prompt and type "netstat -ao" I don't see port 80 even on the list?? So I have no clue why it is closed or what program could be using it.

Any help would be greatly appreciated. Thanks!!

When I try to reconnect or troubleshoot, I am told that no connections are available. All of the other computers, WII, Internet DVD players, etc. are not affected and maintain their internet connectivity. The only way to reconnect is for me to reboot. When I reboot, it takes a long time for the computer to shut down. I am considering wiping the hard drive and completely starting over, but wanted to ask you guys if you have any suggestions that I could try; i.e., reinstalling Internet Explorer, reinstalling networks or something? I do not lose connection as long as I am actively on the internet, only when the computer is idle. All my devices have been unplugged and rebooted several times since this started but that doesn't resolve anything. Try these in order.

1. Try a different port on the router, swap the main PC with another computer's port.
2. Reinstall your network card drivers.
3. Restart the router.
4. RESET the router.

If none of these work, I can offer more..I haven't abandoned my question. I am testing the things you recommended to see if my computer continues to lose connection. It takes time, so I'll return when I've tried them all. Thanks.Good evening

This sounds and awfully lot like a IP conflict, or a HOT router or a miss-configured router.

You can also try this shut down ONE of the desktops that is having the issue and unplug the cat cable and reboot the PC if it boots normally and shuts down normally it is in your router more than likely or you have a bad cat cable etc.

Hope this helps. Quote from: hartbeatmr on July 20, 2012, 03:47:57 PM

My BrightHouse internet connection is extremely slow, 0.4ms. Once in a blue moon it will start going a reasonable speed (5.4ms), which lasts about 10 minutes, and then it's back to being awful. I have changed the router twice, the modem once, and nothing seems to work. I've also reconfigured every computer's IP address. When I called BrightHouse, they say that on their end, the connection is just fine.

I use a Macbook Pro, but we have two PCs and one other LAPTOP in the house, and none of them work. When the PC is connected directly into the modem, the internet works normally.
When my Mac is plugged directly in, it is still slow. Because of this, BrightHouse told me that the problem was that I need to reformat my Mac, which doesn't make any sense at all because my laptop works perfectly fine at other peoples' houses and at school.. Plus the Windows laptop doesn't respond either.

Another thing is, before the IPs were reconfigured, one computer was getting an "IP Address Conflict" error, which is why I did that in the first place. However, it does not seem to have worked. Anyway, when all of the computers are off except for one, it still runs just as slow.

Help! This has been going on for MONTHS. It is very difficult for me to get school work done. I'm thinking of just switching to AT&T because not even our computer-wiz neighbor can figure this problem out. Any ideas?Welcome to CH.
IMHO you would be better off with AT&T instated of a company that tells you to FORMAT .your drive.
AT&T DSL is mediocre, but you get top-notch tech support.
When getting a ISP, look for these points:
1. High Speed.
2. Reliability.,
3. Smart Tech Support
4. Low-Cost.
5. Net Neutrality.
The best you can hope for is mabe 4 put of 5.


Does your ISP require you to use a static IP address rather than automatic or DHCP?It is currently DHCP. I think you have to pay extra for BH to issue you a static IP, which we have not done.also, everything worked perfectly fabulous two months ago, and then it just started getting progressively intermittently SLOWER and slower and now its finally hit a plateau where it's just slow all the dang time.Maybe you need to replace the NETWORK cable for wired connection this time since you've mentioned having the modem and router already replaced. Also the ADSL filter might need to be checked or replace also just in case.Good evening npomeroy

In my area Brighthouse is not available are they a DSL or cable? sorry I don't know

If they are DSL you may have a noise issue because DSL connections are very sensitive to line noise. If so there can be a bad phone / phone line / bad filter / phone jack etc.

If Brighthouse is cable company what kind of cable modem did they give you? Also do you have a AIO package TV, internet, phone etc? In my area for roadrunner they have had issues with the AIO boxes for there HOME services.

Is the cable modem getting warm and I am assuming that your router is not directly on top of cable modem? so the heat is not transferred from one to another. By the way this is not meant as an insult or being a wiseguy

Another thing that may help, is your cable modem doing the router duty and if so is the router set up as just a gateway - AP

If you are set in your router as DHCP coming in (from your ISP) and If I am understanding your reply correct Static on the computers in house and if they are static in house did the IP's get set outside the DCHP IP table. What I mean is If your router DHCP's table is (for computers in house) from say 192.168.1.100 to 192.168.1.150 the static IP's you used were in-between 192.168.1.101 to 192.168.1.149 but this is not including any reserved IP's. Also a reserved IP can be set for say maybe your printer etc. I am pretty sure that you are aware you can not have any two PC's or Printers with the same IP address.

I do see that you said you have replaced the router but out of curiosity what model router?

Hopefully with all the info that are in all of theses postings it will help you get your issue fixed.

Good luck and let us know how it goes. Mike

I hope this posting with all the other ideas here help you, Hopefully I am putting this post in such a way that makes since. Good luck Mike

Is there anyway to have a chrome os linux LAPTOP join a Windows domain? I am trying to BRING new life to older laptops. Certainly not easily, if at all. Particularly with Chrome OS.When you say "join to a Windows domain", which SERVICES are you trying to use? Kerboros AUTHENTICATION? CIFS? Email? You may well be able to achieve your desired results by some other means (e.g. VectorLinux).It is Windows Server 2003, the active directory is used to handle the student and teacher accounts and files and to keep TRACK of the computers on the network. There is no mail since the student and teachers have their own mail as well as mail through our school website. The users would need to log onto the schools domain using their name and password and have access to their files.

The OS is am testing is found here: http://chromeos.hexxeh.net/

It works on my personal laptop at home, I have to try it on the older laptops in school.

Thanks.Whatever the case, on a Linux-based OS, you need to use winbind and/or smbclient. Samba/winbind brings you "net use" tools. There's a good write-up here: http://www.brentnorris.net/samba2005.html It's a bit out of date, but the principles still apply. I'm just not sure how readily available the Samba packages are under Chrome OS.It may all be moot, I can not load the Chromium linux os on the laptop, it is missing pae. I was able to install Vector and that worked just great at home. Brought the laptop to school for further testing and even though the wireless network name and password are put in correctly the connection times out. Not sure if it is because the network is hidden, but the laptop just will not connect.

The wireless manager shows the hidden network, I can changed the config for the network but the connection only times out saying bad password. I have been using this same password for the last 10 years. It works on other laptops.

I am using the Gold version, I will try less intense versions tomorrow.

can you help me . i want remote access on the client desktop software .MANY options out there RDP, VNC, GotoMyPC, Crossloop, PC Anywhere.... You will need the client physically to accept connections on 2 of the 5 listed. RDP, VNC, and PC Anywhere are accessible if you have credentials without user allowing/disallowing, however RDP locks out the current user while VNC and PC Anywhere allows for concurrent access. VNC is free to use for home users although for Windows 7 I believe you have to buy a license.

VNC use to be my favorite method until my one SERVER got hit by BlackVNC when running 3.7. An update to latest FIXES for BlackVNC exploit.

I have used 4 of the 5 above. Haven't used gotomypc but its out there. My favorite for friends and family tech support was crossloop in which you have to be on phone or chat room to share the 6 digit passcode to enter the clients machine. The clients machine generated a passcode and the code is GOOD for only a certain period of time and you enter that code in at your END as the person giving support and you are then given access to their system, (display, keyboard, mouse).

In order to have access you need to know the credentials or contact the client for them. There is no help here for hacking into peoples systems.

Hey! i just got my computer less than a month ago, desktop
for the first 3 weeks, it worked flawlessly, and connected with my Wifi with no problems. All of a sudden, it started to take longer to connect for some reason.

Now, it randomly disconnects and stays disconnected for some reason. ALL other computers in the house are PERFECTLY connected, so the router is definitely not the problem.
Also, i'm using a USB network adapter that is also new.

I currently have AVG anti virus and the standard Windows firewall so i'm not sure what could be stopping the connection. Windows 7 OS.
It says i'm connected, but there is a yellow exclamation saying No internet access, and sometimes saying limited connectivity. Also, it will Re-connect after 30MINS to an hour by it's self. I am so confused. Could it be someone trying to use my wireless connection? doubtful, since the password is very complicated.

Please let me know if you have any suggestions on how to fix this problem. Very frustrated! Any advice is more than welcome. Thanks! Have you tried reinstalling the USB wifi adapter setup driver?No i haven't. I will try doing that now.
In that time, any other suggestions? Thanks! will keep you updated.Well if you are not satisfied with the adapter and still under warranty, you could always return it for a REPLACEMENT. Although you forgot to mention what brand/model is it together with your router.I tried uninstalling the program and re-installing, nothing has changed. The network adapter is the ASUS USB-N13 802.11n, the Router is one given by VERIZON.
I really don't think the problem lies with the router, since all other computers in the house work perfectly. I believe that somewhere in the firewall settings, or AVG settings, that there is something blocking the signal.
I really don't know.
Do you get a good signal? How far is your desktop from the router? Have you tried power cycling the modem/router and with your computer also?The signal is excellent when i'm connected, and is never inbetween. What do you mean cycling?
and also, do you think it could be a firewall problem? Power down the modem for a minute or two together with your PC. Let them re establish connection and see if that changes anything.

do you think it could be a firewall problem?

Greetings - I am trying to add another pc to my wireless lan but can't get it to connect. Here is what I've got:

Modem connected to XP Pro Core2duo

Dlink Gamer Lounge Router DGL 4300

1 Windows 7 I3 TP Link 150Mbps Wireless N Adapter
2 Windows XP Pro core2Duo - Dlink DWA 510 Wireless G Desktop Adapter
3 Asus Laptop EEE 900HA XP Pro

These three are secured by pc #2's Dlink software. The fourth pc is an XP Pro dual core with a Dlink DWL G510 Adapter. It seems this adapter is no longer supported but has been working OK in the past on pc #2. Since I can't get it to connect to the secure network after many attempts at all of the possible Windows options and settings and Dlink software, I bought a new ASUS USB-N13 Wireless-N Adapter thinking my Dlink card was crapped out. Now I can't get this new adapter to connect either. It finds the secured connection but will not connect. It comes back either with an encryption error or it says out of range. Here is the Encryption - WPA-PSK/TKIP (also known as WPA Personal). The distance is only about 30 feet and one thin wood wall to go through. The unsecured connection I had showed an excellent connection too. When I get these windows, I don't get the screen to put in my secured password. Earlier I had a new un-secured connection on this pc, but it screwed up my secured connections on the other three. So I fixed the secured ones again and now I need to know what the heck this old pc wants. I would prefer to use the old Dlink internal card if possible, but the new USB would be fine too if necessary. Every time I have to do this, it's a struggle to get it done right with all of the various windows to check out for various settings. All help is greatly appreciated.

Jim


On the one that is not connecting what happens and what message do you get when you execute the "repair" FUNCTION on your connection?truenorthWindows woodworking is never easy, Except for those people that never have problems.
You can fully uninstall the adapter. Restart Windows and do the network wizard all over again. And this timeline, put the computer near the router. You MAY have to restart the router.
Once you get the connection, put the router and computer back in place.

Also, it there are other wireless things in your area, you should change the channel. Is does matter. Sometimes.

Repair just says it can't do it. I've un-installed the adapter and re-installed both of them depending which one was being used at that time, and that didn't help. There is something wrong between the four of them as when I do get #4 connected as Dlink and not secured, that seems to blow away my secured connections to the others. Also, on some of the pc's still show the OLD connection SSID, so how do I get rid of those? I've removed them from one of the Windows options but they still show up sometimes. Could there be a conflict some place there with the old connections?

JimGood evening frog

If I am reading your post correct you are having an issue changing the sec key.
Can't you go into the Dlink software pick the network ssid and then modify that profile then put in your sec key that you set up? for your network.

Plus I am assuming that your network is set up as such.
Cable modem > Router > then all PC's are connected to the router thru the wireless

Hope this help you, Mike
UPDATE - I been messing with these pc's and finally got them all connected to my new Dlink UN-SECURED connection, so it seems things go to *censored* when I try to make this connection secured. So there is no problem with any distance between them and the router. One of the ORIGINAL Windows errors was something about encryption. Referring to my original post above, pc #2, #3, and #4 were previously secured before adding the new pc #1, so I'm guessing that the new technology in that pc might be screwing up the older ones. Might just be a setting or something, but I'm not Windows 7 literate yet, so I don't know where to go without screwing up something else. Any ideas on this is appreciated.The most likely cause of the problem is having to use a security of WEP or WPA/WPA2 which some of the computer OS or adapter might not support since running without encryption have them connected. The SSID should be understood is your own router access point. Try also going to this link, just in case : http://www.mydigitallife.info/unable-and-cannot-connect-to-wpa-and-wpa2-encrypted-wireless-wi-fi-network-in-windows-xp/Hey Jason, that link looks like the solution for me. Thanks, I'll start messing with it and see what happens. jason2074,
Excellent post and link.
That explains a lot of things about XP wireless.Yes it sure does and when i read it i said this is going to solve the issue.Well done jason2074.truenorthThanks. Hopefully frog would resolve the problem finally.I just now got all pc's on a new secured network, which was the original problem. I used one of the XP's to do it since I'm familiar with the Dlink adapters and their utility PROGRAM. The TP Link adapter utility for W7 doesn't seem to be on the system. I don't know what happened, or how it happened, or why, but all are now secured and problem solved. Must have been a setting someplace that got the right tweek this time. Thanks to all of the input here.
Jim

Ok, so here i go

I will be RUNNING some dell rack mount SERVERS very soon, and i would very much so like to take care of setting up the sub domains to them myself from another server in my network, if possible.

I have heard of the functionality for websites using a built in feature to apache, which i would also like to know more about, but my my main concern is the fact of how i can create sub domains to route to different computers on the same network.

Something like in this summary:

192.168.1.101 runs main website (of the default domain of domain.net)
192.168.1.102 runs sub domains to the rest of the servers
192.168.1.103 runs server, accessible publicly through domain.net, game server. (port 25565)
192.168.1.103 runs server, accessible publicly through 104.domain.net or so running a game server (port 25566)
192.168.1.104 runs server, accessible publicly through 105.domain.net or so running another game server (port 25567)
192.168.1.105 runs server, accessible publicly through 106.domain.net or so running yet another game server (port 25568)

i would like the sub domains to re-direct to the address of the server with a port, so the user does not type in the port. however, have the same sub-domains on the website, as to have the web server have the map of
192.168.1.101 has sub domain 104.domain.net direct to a website folder of /var/www/104/
192.168.1.101 has sub domain 105.domain.net direct to a website folder of /var/www/105/
192.168.1.101 has sub domain 106.domain.net direct to a website folder of /var/www/106/
192.168.1.101 has subdomain mc.domain.net direct to a website folder of /var/www/mc/
192.168.1.101 has subdomain mchosting.domain.net direct to a website folder of /var/www/mchosting/
192.168.1.101 has subdomain kat.domain.net direct to a website folder of /var/www/kat/

A setup like this would make me happy right now, but if ANYONE knows of a better way to make this, please do let me know, thanks.

ubuntu 11.10
apache/2.2.20 (ubuntu)
can install other packages if needed, thanks. Good evening zeroburn

Are all the servers you have listed other than 192.168.1.101 box real servers or will some of them going to be virtual?

Mike These servers are all actual servers with MOTHERBOARD and whatnot. Although learning how to make the virtual servers work with a domain would not be a bad route as well, if you have links, i will read through the information

Right now, i am mainly concerned with the subdomains pointing to other real machines in the network

Basically, just wondering if I can connect my Router to my Modem without haveing to run a CAT 5E. Just wondered what had to be the same on the router so that it can see the modem an let my other wired machine connect too it.Welcome to CH.
Are you now using DSL? What did you have before?

One provider PUTS it this way:
Quote

Using the provided Ethernet cable, connect the modem TON the WAN of your wireless router. Both the modem and ant router must be off. You rcomputer should be connected to one of the LAN ports of the router. Then computer also should be in the power off state.
Next turn on the power in this order:
1. Turn on the modem, wait 30 seconds.
2. Turn of the router and wait 30 seconds.
3. Last turn on your computer and let it do the normal start-up. This may TAKE two minutes for some computers.

I all ways had DSL but, I dont want to have to run a cable through the ceiling.

Will using the home wireless from a phone or laptop track the activity to the computer? If so, where? THANKS. Are you looking to track the activity of the Wireless devices, or the wired ones?

I'm assuming the computer you've mentioned is wired into a WiFi router on a ADSL broadband connection.

The short anwser is: probably not.

The long answer is: maybe, depending on how the network is setup.

If you're looking to set something up, please let us know more about exactly what you're trying to achive.it will track a lap but maybe not your phone depending on how your SECURITY is set up, you are trying to prevent tracking on your phone and lap, correct???.........................gettingthereGood evening mej0709 and welcome to CH

If I am understanding your question correct you are wondering if anyone (your ISP)(Cell phone company) is tracking you and if so how?

If you are hooking your laptop thru your cellphone (like tethering) then chances being "yes you are" most smart phones have a GPS CHIP and IMEI most cell phone companies will tell you that you are NOT being tracked but they can do it and if court ordered can do so.

If you are not running the laptop thru your cell phone and your laptop is on your home network like connected to your home router and that goes to your (ISP's) cable / DSL modem well once again yes they can but only while you are on your home network and really you are not physically moving anywhere they can track all web sites, files downloaded etc. All ISP's have to keep track off every customer because if they are Court ordered they have to turn the info over to the courts.

If you are using your home wireless network for SURFING the internet with your cell phone than the same hold true about the above with the ISP (internet provider) will still keep track of what web sites, files downloaded etc. The ISP will also know it was done with a cell because of the IMEI which is uniquely identifiable to each cell phone.

Well I hope this helps to answer your questions and hopefully doesn't make you to paranoid.

Hello
I am setting up a free wireless internet using router for a Coffee SHOP. as it will be free then everyone can connect. i WANT to mange user connected and limit the internet for costumers of the shop.
can you introduce best software for managing the wireless network and its users ?
thank you

is there a software that manage wireless network look like Bluetooth.
when a Bluetooth device try to connect to PC, the manager software on PC creates a code for the Device. when the PC verifies the code then the device can connect.
do you know any software that has this feature for wireless network?PLEASE use separate threads for multiple unrelated questions.

To answer your first - if you use a Linux box with a wireless network card, you can provide browser-based access to wifi using something like ChiliBox: http://www.chillispot.info/. Or you can install the OpenWRT router FIRMWARE on certain routers: http://wiki.openwrt.org/doc/howto/wireless.hotspot

This article lists a few alternatives: http://www.smallnetbuilder.com/wireless/wireless-howto/30150-how-to-build-an-open-source-wi-fi-hotspot-with-dd-wrtthank you for replying
i apologize for sending 2 posts. i forgot to post part 2 with 1 then i had to TYPE second part in another post.

Hi,

At home I have a tenda router (not WIRELESS) which is then connected to a wireless tenda router. I sort of inherited this setup. I've had the two ROUTERS connected to each other for a while now and have been using the wireless internet with the yellow unsecured badge showing and I want to get rid of it.

I am computer savvy enough to know how to hardwire into the router, do the admin/admin thing, go into security settings change it to WPA2, choose my password etc. But when I finish doing this I am able to CONNECT to the wireless but I have no internet access.

I am unsure of whether both routers need to both be passworded? Does the wireless router need a password on it? Or just the ONE feeding the wireless router? Is there some other setting which needs to be coordinated between the routers so I can have secure wifi?

I have experimented around hardwiring into each router and changing the security settings but always end up in the same situation of being able to connect to the wifi but having no internet access. If I choose unsecured then I have my wifi with internet access back.

Any help appreciated.Wireless router should preferably be in bridge mode. If it has a DHCP server, it should be set to give the other router's IP address as the default gateway.

Does that help?

hey guys i just bought a new dlink n750 router, and im having some problems setting it up
i followed the installation tutorial via the cd, and SUPPOSEDLY SET up the 2.4ghz and 5ghz bands, however only the 2.4ghz one shows up.

-im not SURE where to look for the software or w.e to check whether the 5ghz band is hidden, as the setup cd didnt seem to install anything?
-despite being able to connect to the 2.4ghz, my download speed is terrible/non-existent. this is a problem because im trying to deal with an entire other can of worms on another computer, and im trying to download drivers for that one from here. The downloads start, but they promptly lag out and stop (est. download time goes through the roof).

can someone possibly walk me through this setup again/point me in the right direction/shoot me a link to a guide/tutorial for this? i couldnt really find anything USEFUL via a PRELIMINARY search

Hello, I just PURCHASED a USB 3.5G modem - model: K190 made by KTech and I need its drivers/software.
It doesn't work (EXCEPT the extra SD memory card capability) as it doesn't have any drivers or software on it, CONTRARY to what the store clerk said, maybe there's a defect because I already tried it on two different laptops.
Certainly, it didn't come with any CD or manual nor can I give it back. The company doesn't have any website and there are no drivers to be found on the INTERNET.. I spent hours looking for the modem's drivers..
I would be very grateful if somebody could help me out and if possible, send me the software/driver of this modem to my email address: [emailprotected]
If somebody from this website doesn't help me, I will have to throw it away:( I paid $25 for it.. I realize that for some folks it's nothing, but I'm quite poor and I can't AFFORD to buy another model..
Thank you for your time and help in advance.
Greg

Hi there, I'm MOVING to university in the next few days, and I've been informed the HALLS I'm staying in come standard with a 10mb broadband connection via an Ethernet port, but some former students have informed me I can convert this to make it WIRELESS. What would I need to BUY to do this? A router? Or a wireless access point? Or do I need to do more than just plug one of those in?
ThanksA wireless router.Not a router. A WAP will be sufficient, given that you have an ethernet port. Many of these are pretty much plug and play - very easy to set up and use. EG:

http://www.misco.co.uk/product/164579/TP-Link-Wireless-N-150Mbps-Access-Point
http://www.misco.co.uk/product/Q122554/D-Link-Wireless-G-Open-Source-Access-Point
http://www.misco.co.uk/product/164207/ZyXEL-WAP3205-802-11n-Wireless-Access-Point

Personally, I would avoid the cheap and nasty option, but that might be adequate and within budget for student uses. Plus, the chances are that someone else will already have done this in a nearby room and you might be able to share the access point and the cost.Thanks for the help

There was a discussion many years ago that this guy claimed at a computer show to have teamed up NICs between 2 systems to have 200mbps bandwidth between 2 systems in a peer-to-peer running linux, where each computer tower had 2 NICs and each computer was networked together with 2 cross over cables. I was thinking about this today as I was LOOKING over one of my computers with 2 NICs and was thinking I wonder how hard it would be to team NICs and multiply bandwidth between them using cross over cables that wont compete for bandwidth thru a shared switch which would bottleneck at 100mbps if a 100mbps switch. Each cable has dedicated 100mbps bandwidth with nothing to compete with.

Has anyone done this or seen it done to explain how you do this? I am interested in trying this out if it can be done easily. The guy stated that this is SIMILAR to an earlier project in which 2 x 56k modems were teamed to give 106k bandwidth due to 53k limit of 56k modems, with 106kbps connection to the internet thru 2 independent connections to ISP using 2 phone lines.

I was thinking about doing this with 2 computers both with Gigabit NICs to have potentially 2000mbps bandwidth between them if its doable. I prefer MS OS, but have knowledge of Linux as well. Reason for MS choice is that most applications I have that can use better bandwidth are MS compatible software with local file sharing.I've never seen or heard of this myself, but when thinking about it I still think that there is going to be a bottleneck somewhere in the line that would limit the connection.

• First, doing this on a broadband connection It's likely that you're only going to be getting at most around 10MB down, which is plenty for one 100MB cable can card to support without needing an extra card.
• Second, most websites and services will limit how much each visitor can download. Usually you're going to probably only get a max of a few hundred KB from one site and maybe lucky to get up to 5MB from some sites and download services. Having an extra card on the same network is going to share the same IP (I'd imagine) so it wouldn't be possible to bypass this for a single site.
• Finally, if this is possible I'd imagine you'd only get support and steps on how to do it in Linux and not Windows (if it was even possible in Windows).

I was thinking about doing this with 2 computers both with Gigabit NICs to have potentially 2000mbps bandwidth between them if its doable.

Hi everyone, here's the situation. I visited my mother Friday evening. Mom has a desktop PC and connects to the Internet via Ethernet cable running from modem to PC; her current ISP is Time Warner Cable. My sister-in-law left her Toshiba laptop at my mother's house and wanted me to install antivirus software on it. To connect to the Internet with her laptop to download antivirus software, I disconnected the Ethernet cable from mom's PC and connected it to the laptop. This did not work; the laptop would not connect to the Internet. I TURNED off the modem and restarted it with it connected to the laptop. This established an Internet connection for the laptop and I was able to download the software.

Now, when I disconnected the Ethernet cable from the laptop and connected it to the PC, the PC would not connect to the Internet. I turned off the modem and restarted it. Again, the Internet connection was restored, this time for the PC.

I'm wondering why I needed to do the restarts of the modem. I have taken my Compaq laptop to my mother's house and connected via the Ethernet cable; this was with an older modem and a previous ISP and I did not have to restart the modem. And, my son visited me about 2 weeks ago and brought his MacBook computer and I simply connected an Ethernet cable to it so that he could connect to the Internet; no restart of the modem was required. Cable modems have no routing capability, so everything you describe is normal. The first device connected to the modem gets a public IP, different device...different public IP. If the older modem didn't do it, it was probably due to different CMTS (head-end) hardware, on the ISP's side. ROUTERS give additional security because of Network Address Translation (NAT). Most LAN's USE the same addresses, i.e. 192.168.x.y
BTW, DSL modems almost always have a built-in router.Thanks, CC, that all makes sense. The previous modem I mentioned was the one she had with her previous ISP, which was a DSL provider. So, it must have had a built-in router. Some cable providers give you a combined modem/router, mine is a rebadged Netgear. If you see more than one Ethernet socket it's probably a router.Just to make it more complicated:
Some cable modems have an integrated cable modem telephone for VoIP, aka E-MTA (EMBEDDED multimedia terminal adapter).Quote from: Salmon Trout on September 16, 2012, 03:50:32 PM

It only has one Ethernet socket.

Ok, so i have one of these addtron adh-1016 16 port HUBS. I connected it through some CAT5 to the router of the home, then out to the computers, plugged it in, and nothing. It is my understanding through experience and through reading that network hubs, switches and whatnot do not need to be installed with a CD or other type of media.

Question is, why is this not working.

I have several computers hooked into an 8 port switch right now, and i am looking to expand, and they all work with the 8 port with all the same cords and everything. My main question is why would the new (well, old, but new to the network) not decide to work.

I can not, for the life of me, find a manual anywhere on the net for one of these.

I might as well TRADE it in for a rack mount switch if i cant get this solved.

thanks everyone. Welcome to CH

Hello to all. I am running my network and am wanting to create a subnet, if thats what i am actually looking for.

I would like to have my server rack to have a firewall and seen by the rest of the network as one ip, i guess is my goal.

I want to do this so that my EXPERIMENTATION and projects would not disrupt the rest of the network, and so i can set up DHCP, a firewall, ext inside the network.

If anyone knows how to do this, let me know. Thanks. You could use a NATing firewall/router, or you could configure one of your SERVERS as a router - ideally it would need at least two network cards for that. Then use separate physical network switches for each network, or use the VLAN capabilities of a managed switch.I have some Entresys Matrix E7 chassis with managed switches, but i am in need of reading the manual through first (over 1000 pages). On the servers using the new sub-network, what configurations would need to be changed? (Ubuntu Server 12.04)

Thanks for helping out. I agree with Robs suggestion to have 2 NICs and physically isolate the networks as the best and easiest method.

I have never run 2 DHCP's on the same network, but I suppose one way to have 2 DHCP networks running on the same network and not compete would be to assign reservations for devices by MAC ADDRESS to designate which DHCP's would handle each NIC. Lots of work, and if you have DHCP (A) and DHCP (B) and a reservation for 01:55:EF:04:77:3A on DHCP (B), I would think that you would have to black list it from DHCP (A) so that DHCP (A) does not give it a dynamic IP from its subnet. This is hypothetically speaking since I have never attempted to run 2 DHCP's on the same LAN. There is the chance that both DHCPs would battle it out competing to be heard. As well as what happens when you introduce a new Networked device to the network that has no reservation on either, would both DHCP servers try to give it an IP or would it be the DHCP server with the fastest response to the request for the stack. And the worst scenario a network storm crippling the network! Quote from: zeroburn on September 11, 2012, 03:48:41 PM

I am paranoid that google is watching me, because they have been sending me tracking cookies, i formatted my PC and when i go to google stuff, it still auto completes, and sites i been before are purple in link....how does google know i have been there before? I did 3 clean installs of windows today.

Does my isp TRACK my browsing then tell google and everyone?

what all can i do?

i need to secure my PC - then all my emails - and restore my tablet and cellphones with custom firmware.

I am tired of being a victim of the system!

What else do i need to do?

Does my ISP track my history? will a modem reset fix clean it?also i have started using secure search engine.Have you thought about SEEING a doctor?
If he is really paranoid, Here are six things he can do:
0. Take Prozac daily
1. Legally change his name.
2. Move to another city.
3. Buy a new PC and cell phone.
4. Ignore all his friends.
5. With no friends, no need for e-mail.


Hey what is the most private email?
Found hushmail, but the fact they try to prove themselves with testimonials makes me think its a trap

Don't trust google so either hotmail or yahooQuote

OK.

I have a machine running on windows xp x86, and a laptop running on windows 7 x64. I have an HP laserjet 1009 printer attached to the xp machine, with sharing turned on. Until yesterday, the printer SET up that I had was fine - the windows 7 laptop was recognising the printer and would send documents to it to print. Last night, this stopped working for no apparent reason. The only thing I have done is to replace the adapter on the xp machine, because it was broken I discovered, but I have set up the share again since INSTALLING it and now the windows 7 machine wont find either the xp machine or the printer on the network.

Any ADVICE regarding how I could solve this problem would be appreciated.

Cheers, guys. :-)

feenixWhen discovering wifi devices does the xp system with the new wifi nic not show? Did you install the driver in the correct order, where most have you install the driver CD first before the adapter is installed so that the adapter is associated with the MFR drivers and not MS default? Most adapters like this have a label on the device or CD warning that order of INSTALLATION is critical.

My web site, www.geekk9pm.com, is bering blocked my Malwarebyrtes AV SOFTWARE. I bought the software just a few days AGO. It seems the host company I USE sends out something to the computer that is flagged as dangerous.

Anybody else every had this sort of thing?
Never been blacklisted like that. Does your site have any routines / scripts in it that are showing as a false positive to potentially dangerous sites? The MailTo: Form Data routine use to nab me with Norton Internet Security a long time ago until I did away with that.

I cant go there from work computer to take a peek, but is this a free web host that has redirection advertising which could be black flagged?My web site has been on four different servers. Most of the content is a WORDPRESS blog. I start up the site with a blank WordPress blog. It is the only script I use.
It seems there is no way of knowing if content is being the TRIGGER. At least on on-line scanner gave the site a clean green ratting.
I don't have the tools to tell me why the site is being blocked. Some research only implicates the IP address, and from a time prior to my first use of that IP.
Maybe the only solution is to get another server. Again.

Hi all people .

I have been trying for a while but cannot join 2 Pc's together and although many sites online say I can do this easy ..I cannot ,,,,maybe its just me ,......

what I have is ......

Computer A , a Dell running Win XP this is the main ONE and connect through an ethernet cable to a small D-link box to broadband ....USB 2.0

Computer B .....A Compaq ...also running win XP ,..not connected to anything , but would run onlie OK if i transferd the connection over ., USB 1

I also have a USB netwoking cable from BELKIN , i belive , wich is USB to USB 2.0

It would be best if I could actually share the internet connection between them but failing that the at least send files between one to the other .....

The idea is that to stop the kids bugging me they can use the other computer (compaq) so I came up with the brilliant idea of joining them together so i dont have to upload games save them on a Memory stick then manually put them into the other one ......

ANyway no matter what I do I cannot make any computer see the other one ....i try it from both ends and have the same software on both computers ......


Question ,, what is the best way of doing this ?
Maybe its just a different approach ?

But thanks for trying in advance .....
You may have to reply USING small words for me ,,,..... You sure its USB to USB. Also is the driver installed? I think so ... but Im really not sure ,i will check and maybe just do a complete re-install to make sure..Now I have a better idea , some one point me in the direction of a cable and software that will do the job and i will have a look at that instead , it may be quicker and simpler for all ( me and you ) in the long run .....Deal?
What ISP modem and router model are currently being used? The WAN port is better and widely used nowadays.http://www.leeindy.com/connecting_two_computers_using_crossover_cables.shtml
truenorthTo add to the cross over cable you will have to setup the computer that is connected to the modem to internet to act as a gateway for the other computer that is connected via cross over cable. This is an unusual setup for DSL or Broadband but would work. I setup a setup like this for a dial-up user who had 2 windows xp computers that they wanted both to be online at same time competing for the 56k bandwidth vs just 1 system.

If you have DSL or Broadband, I would buy a router that has 4 or 5 network ports, and then connect Cat5 CABLES from both systems to the router. This will allow for the computers to operate online independently.

The problem with a cross over / ( internet sharing ) gateway setup is that the system that is acting as the gateway has to be running for the computer sharing internet thru it to operate online!

As far as PC to PC communications over USB, I have only seen USB used for TRANSFERRING files from PC to PC similar to the old LapLink setup.

Hi Everyone,

I NEED help on how to effectively utilize my internet bandwidth provided by my ISP. I am using a DIAL up type of network through a usb modem. The indicated connection speed is 7Mbps but during browsing i experience slow and choppy network. Download run at a speed of 12kbps.

I want help on how to effectively utilize about 1/3 of my bandwidth.

Thanks in advance.
~Akod7mbps leads me to believe you have DSL, But 12kbps sounds like Dial-up unless the sites your visiting to download have a slow backbone to the internet.

Please run www.speedtest.net
and reply back with upload and download speed.

What is the make/model of the modem and computer as well as OS of the computer?Quote

network through a usb modem

this is the error that appears http://attachments.techguy.org/attachments/177591d1282515017/techsupportguy.png

this is all worked GROUPED too. Not sure if it's realities to this home group thing
Good MORNING Ryuk and welcome back to CH

Sorry but I am not trying to be a wise guy

The attachment you gave us it looks like the PC is trying to connect to "Server" is this sever in a domain? or are these PC in a home network?

If this PC is trying to log into the domain make sure the user name and password are correct. If this is being done in a Domain click on "use another account" and just put in Laurel with the password.

Hope to hear from you soon, Mike

I'm trying to set up a music-streaming program called Icecast and I'm running into trouble portforwarding. I followed all the steps from Portforwarding.com's tutorial but I still can't connect to my own computer through my external IP. Firefox just says the server "is taking too long to RESPOND", but it should work. I managed to connect successfully to http://localhost:8000/stream , but when I change that to my external IP (and change it in my config file) I can't connect to it through the remote IP (and obviously not localhost either).Port Forwarding is different for every router, so I don't know if I could solve the PROBLEM router-wise.
However, I had the same problem once, and I solved it by ALLOWING connections through the Windows Firewall.I checked Windows Firewall and I set rules for both TCP and UDP for incoming, and for ANY connection on outgoing, yet it still fails. Comodo Firewall is set to allow all requests inbound and outbound for the program as well...

I don't know what I could have messed up on portforwarding-wise. It's a fairly straightforward procedure for my router. The only part I actually needed to look up was how to set a static IP on Windows 7.Oh well, I just decided to RUN Icecast through my server and USE *censored* on my computer to send the music directly.have you tried lowering your routers firewall?If you're trying to connect to your own external IP address from within your LAN, you may encounter a problem called "hairpin NAT". Very few consumer routers are good at handling "out and back in again" connections. Most DrayTek or Cisco routers can handle this, but cheaper kit is often going to struggle.
