Vista - Wireless network problems

Hey guys first of all I'm on my iPhone posting this, so sorry if there's spelling mistakes,

I've got a problem with my wireless network, I've got a dlink adsl2+ router 604gt or something (not at home ATM) it was working fine last night not a problem at all, had dinner then went back to the Internet and it wouldn't work page could not be displayed etc, logged into modem all is good it's got internet acces and working fine.

So I left it for the night and this morning I tried again and windows can't seem to get an ip address from the router it comes up with the 169.254 etc etc takes agesbto identify the network and then finally displays limited connectivity.
Tried manual settings to no avail, tried restarting both computers and still doesn't work,
I just don't know what could have changed in the 45min that I was away from it. Any help would be good.

Ps, modem still registers inter access and looks to be I'm full working order just the computers have a coniption when trying to be friends with it. Ta guys

try unplugging everything for thirty seconds, then restart.

Hey mate,
I have tried that a few times, I havnt spent a real lot of time on it, hopefully this arvo I can have a real good look, I might try disabling wep etc

hi again
