i have been using a WRT54GS LINKSYS ROUTER for 2.5 years problem free until now. All of a sudden i cant connect to the internet through it at all. when i diconnect it and hook my desktop directly to the modem it works but i need the wireless to use my laptop. I have tried everything to get it working again, no dice. when using w7 diag tool it reports back local area connection doesnt have a valid ip config. anyhelp would be appreciated. thanks stv357
