Solve : Network not pinging?

Answer»

I have set up a home network, the two pcs are showing in the network and the ip addresses are showing diffenent (one ends 0.101 the other 0.102) when I tested them on PC1. On the other PC2 it shows the network name, but cannot open the folder without an error message occuring and computers dont show. The LAN connection (shown through main PC1) ends 0.100 and the standard gateway 0.1, also I am not on PPPoE but dynamical assigned IP address from the provider.

Whilst opening the 2nd PC in the network on the main PC, the error message "communication with the 2nd PC is not possible" occurs. The network DIAGNOSIS sent a ping-signal to the remote host but didnt receive an answer. Internet works on PC2 though through the wireless connection and Zonealarm firewall on PC2 is set to accept the IP address on PC1.

On the main PC under 'ipconfig' there are 4 tunnel adapter LAN-connections Whilst the local connection IPv6 -address is filled in, DNS-suffix and standard gateway arent. I have no idea what this concerns.

I can only think that Windows Live OneCare is having some bad influence with the connections on the main PC as I cannot set the IP address of PC2 to be set in the firewall. But OneCare shouldnt cause a problem, because I am trying to access PC2 from PC1 (pinging OUT shouldnt be a problem?)

I have also read that on the Vista machine I have to make sure the LAN connection is set to "Private". What does that mean, because my LAN status is set to IPv4 connectivity "internet" and IPv6 connectivity "local"  are there no network specialists out there....

I HAVE THE INTERNET CONNECTION GOING NOW - PLEASE READ FROM MY NEXT POST BELOW.
(occasional disconnection)First thing I would do is run this command on all computers. 

ipconfig /release

and then run this one

ipconfig /renew

Your router has to be assigning IP addresses via DHCP though.  What this will do is release all information pertaining to DHCP and then reassign it all.  Hope that helps a little bit.Try disabling all your firewalls temporarily... does that change anything?Finally I SOMEHOW got the wireless network working by manually setting the ip address on the host PC etc.

Now the only problem I have left, is that the internet connection keeps on cutting off after several minutes and then comes back again after about 10 seconds. I thought at first it would be the other PC taking bandwith away, but I cant get in the internet (browser) on that other PC (I dont need it there anyway).

The reason why I think the internet connection keeps on dropping is because the ip goes through the router via standard gateway. So it isnt REALLY a direct ip connection to the provider. Otherwise it could be a not well enough defined setting in the router configuration panel?

How about fine-tuning the DNS or the buffer... I saw those settings on the advanced tab in the LAN connection properties (Network configuration). Also I noticed that the RPC-service is blank in the lower 'Client for Microsoft Network' option - dont know if this means anything, as there one can select 'Windows Locator' or 'DCE-Cell' in the drop-down bar.There are some fine configuration settings in the router browser available...

False. I have no idea for those disconections, but it is not what you said about IP "goes through the router". I don't know about that setting for disconecting after a idle period of TIME, you'd better check (both on conection settings on your computer, and also on your router).

You don't get disconections because of DNS or buffer. I have no idea about that RPC-service.

Well seeing as you know what I am talking about you already seem to be very experienced 

I checked in the router browser the modem settings and yes, it was set to 30min idle time. But seeing as the check box "Backup dial-up modem when the broadband connection is not working" wasnt activated, it shouldnt have any effect. Anyhow I'll try this and get back to you if it doesnt work.

I dont know where I should find the time out settings on my computer?OK I did that, but the internet connection still drops from time to time. Here's what else I did:

- tried to set the dynamical ip to static and inserted the actual ip address in the router settings. But the LAN IP settings (TCP/IPv6) wouldnt accept the same ip address and had to change back to dynamical (Error message: The inserted network address is invalid)

I searched again in the router browser "Advanced settings":
Dynamic Routing - Dynamic settings:
send:  is on disable (options available are RIP1, RIP1 compatible or RIP2)
receive: is on disable (options available are RIP1 only, RIP2 only or both RIP1/RIP2)

Modem settings:
Is set to 115200bps (28.8k/33/6k/56k modem or ISDN TA) - should I change to the lower 57600 bps settings (14.4k/28.8k)?
I have a cable connection of 4000 (hispeed download speed I suppose, so not ISDN)
Otherwise maybe the settings are set too low and should go to the higher modem settings?

I have no idea if I am on the right track here.... 



No, don't play with dynamic routing section of your router; those settings are ok (disable on send/receive RIP packets). RIP is used to create a network map common to all routers inside a small (but not so small) network, with at least a few network adresses and at least 2 routers, so each router would know where to send data for a certain part of the network.

Modem settings: connection to your ISP is through: a) phone cable, b) tv cable, c) ethernet cat5e cable, d) fiber optic cable?
I really don't think that a) or c)  are true (but you know better and for sure , so please tell us). I don't think you are using an ISDN WAN connection. My assumptions is that your are using an ADSL connection (through tv cable) or fiber optic.
Anyway, it does not have anything to do with those interruptions. There is something else.I have a cable connection on a hispeed 'tv' connection, not ADSL nor ISDN (those are on analog copper WIRES, like the telephone, or slower ISDN-fibre wires)

I have actually just moved my wireless telefone into another room - that may have had some influence.


EDIT: Nope, unfortunately the internet connection still occasionally has a signal loss - then comes back again after a few seconds.
I think the problem is local because if I do a direct connection to the provider without the router then the connection is normal ! (no weak signal)
Is there not some kinda freeware log-program to track (not measure) the signal strength and find out the cause?
