Answer» Hi all.
I have attached a drawing of my set up.
I have had this set up for a few years now.
The problem is that since I changed my ISP and router I cannot get the AP in the loft to keep it's settings.
I have a HUAWEI HG523a router as used by TalkTalk. (Was a Thomson)
The loft AP is a D-Link DWL-900AP+, Ver C2.
This is a step by step of what I have done since the connection dropped.
Went up the loft to reset the AP.
Logged in to the IP via web browser, 192.168.0.50.
Went to ‘Advanced’ and chose ‘Wireless Client’, did a site survey and chose my network.
I then set the AP back to an ‘Access Point’.
The site survey loaded all the settings in the ‘Wireless’ options, SSID, channel number etc.
I didn’t bother with any WEP Encryption at this point.
I gave the LAN settings an IP in the same range as my ISP router and entered the gateway number.
I gave the AP an SSID ‘Workshop’
I restarted the AP and logged in using the new IP.
All settings HELD.
My iPhone found the new ‘Workshop’ network and connected no problem.
I went to my workshop to see what was going on up there.
I was again able to use the ‘Workshop’ network to browse with my iPhone.
I found the ‘Workshop’ network on my workshop PC and asked it to connect.
As expected It told me there was no security, I asked it to connect anyway.
It did, signal strength excellent, status=connected.
As soon as I tried to use the internet all connections were lost from the AP.
I tried accessing the AP from my HOME PC but somehow the settings had been changed and I had to reset it again.
So I tried these settings in the AP.
192.168.1.254 for IP
255.255.255.0 for Subnet
192.168.1.1 for gateway
Password protected the AP.
WEP encrypted the wireless network.
Tried my iPhone, works perfectly.
Tried my Vista laptop, works perfectly.
Left the house for an hour or so, came back and the AP is inaccessible again.
Laptop not able to connect nor iPhone.
This is without turning on the workshop PC.
I don't see how the AP can have it's IP changed?
This is something simple but what?
It must be something to do with the new router, like a lease time issue??
The workshop PC is XP
The laptop is Vista
The home PC is 7
Then there is the iPhone
I have tried changing the security in the router to WEP so it matches the AP form of security, still no good.
Has anyone got a clue as to what I can try next?
Cheers.
[recovering disk space, attachment deleted by admin]If settings are not holding the AP is either getting hacked by someone who is messing with your settings or for some reason the AP is LOSING its settings when power is disrupted etc. If you configure it to work and then unplug the AP from power and then wait a few minutes and then plug it back in, does it still work? I am guessing your using a password for your wireless devices that is not easy to guess and not the default from manufacturer such as password or admin etc.
Your picture is interesting as for I am not sure why you have 2 cables going to the AP, when only 1 is needed to the router.Hi Dave, thanks for the reply.
It is definitely not a security issue, I have tried leaving it open to make it simple and password protecting the AP and the network.
The failure happens the same way after pretty much the same time.
I am doing exactly the same as before I had a router change and never had any issues.
Not sure what you mean by the two cables?
The router shown in green is in my lounge and that is connected by Ethernet, the short brown cable on the right of the router,
to my home PC.
The brown Ethernet cable coming out of the back of the router is the one that is feeding the AP in the loft which in turn is connected to the antenna via the purple cable.
The only other cable is the one marked 'A' which is doing nothing at the moment (it is on there as I was going to change my set up at one stage so you can ignore it).
Today I am going to reconfigure my old router to see what happens.
If all runs ok then there must be a compatibility issue with the AP/router.
The AP is 802.11b only so I'm wondering if that is the grief.
I know the n/g stuff is usually backward compatible but not sure if it works the other way around (probably not without a firmware update and this AP is now obsolete).
I may end up having to use power line adapters, I think these use the earth cable on the electricity circuit?Quote I may end up having to use power line adapters, I think these use the earth cable on the electricity circuit?
I used a pair of these at a food store vs stringing Cat5e plenum cable about 200 ft through the rafters 30 ft up above the sales floor. I found that they worked as a good network bridge when connected to outlets that were running off the same phase, but if plugged into an outlet on a different line phase they didnt work. You would probably be ok with them, but just wanted to mention this observation from my use of them. I lucked out and an outlet on the opposite wall of the network switch that we were adding was on the same phase, so I just had to dress a Cat5e cable around the storage room where this device was used. Never tried using these other than as a quick and simple bridge to the servers at the back of the store to the pos systems and deli scales at the expanded portion of the store when the store bought out the neighbors space to knock down the wall and expand in. (Really happy I was able to convince the GM not to go with a wifi cafe setup to the modern cafe they wanted. My statement of that it would cause people to never leave and the limited seating would anger people, so just make the food and beverages available, but dont give them a reason to stay beyond that! )
QuoteThe failure happens the same way after pretty much the same time.
Strange that it happens after a same period of time. If the power is noisy, I'd have the AP powered through a line conditioner or a UPS which will ensure that dips in power dont cause the AP to act up.
QuoteNot sure what you mean by the two cables? I saw the unused cable labelled "A" that went diagonal and it appears that its left over from an earlier setup possibly. Since an AP only needs 1 cat5 cable connection.
Well, not quite sure which setting sorted it, but sorted it appears to be.
I started again with different but identical AP.
Left everything as basic a possible.
Changed the Beacon Interval to 197 from default of 100.
Got solid connection but a very weak signal.
Changed the Antenna to external from the default of diversity and over a minute or so the signal strength changed to very good.
Been a good connection for over a week so it looks like it is sorted.
One day all this will be simple!!
Thanks for the help and suggestions.Glad its working ok now. And thanks for reporting back what fixed this in case anyone else out there hits this on google search for similar problem.Can't Decide Which Network Gear You Need
