Is it just one PC or all of them?

Have you tried turning the router on and off?

Presumably everything under TCP-IP settings is set to automatic?

Drop to a dos prompt and type in "ipconfig /all", check in the information listed that the dhcp server is actually the address of the router in question.

If it is then type in "ipconfig /release" followed by "ipconfig /renew". If dhcp (within the router) is active and setup correctly the adapter should get a new ip address, assuming the nic card is not faulty, or in the case of the wireless the access key/encryption settings have been set accordingly.

its just his pc. been happening in two different houses, with two different connections and routers.
i think its all set to automatic. i'll double check.
andd. i'll do that ip config thing in a minute and see what happens

i probably should have mentioned. its the connection in our house that hes trying to connect to. the rest of us can and could in our last house. but hes not been able to connect to either or his one at home

I had an issue with this, check ipconfig /all on command line, you might get an RPC Server error, in which case 'sfc /scannow' should fix this

Infact, the sfc /scannow wouldn't hurt anyway.

Did you resolve, any joy? Might be worth refreshing winsock as well using the following at the command prompt, type in "netsh winsock /reset".

Focus on fixing the wired connection issue forst, once you know what's wrong with that you can then deal with the wifi issue.

DHCP is enabled on the router isn't it ?
Is the NIC showing up in Device Manager ?
Is he running any firewall software ? If so disable to eliminate it as a variable.
Has he reinstalled/updated the NIC drivers ?
What happens if he set's the IP manually in the correct range/gateway set etc ?
Have you used a different cable and swapped the NIC out to eliminate it being a hardware issue ?
Does the NIC light up to indicate the connection is good ?
Have you tried a live CD as if you have the hardware support then this will often confirm the hardware works when correctly configured and point to it being a software issue on the host OS ?

Haven't mentioned if your friend is using Vista. If so, then it may be the well documented 'network but no internet' issue.

My take on this is that the Vista TCP/IP stack is causing problems with some routers.

The router gives out a working IP address via DHCP, but doesn't give the DNS gateway information. Hence PC connects to the LAN, but can't see beyond it to the Internet.

Solution ? (at least in my case)

Set up TCP/IP profile manually - works a treat (and a lot easier than trying to update router firmware, when in all other respects the router is stable.
