win7 suddenly not detecting wireless

i upgraded my desktop machine to windows 7 a few months ago. i had absolutely no trouble whatsoever - everything was a dream right off the bat. however, suddenly today it is no longer detecting any wireless networks. I did not install any software or upgrades of any kind or change any settings. used the internet a few hours ago (just for email, though), then suddenly nothing. i know its not my network b/c there are two other machines in the house that are still connected (incl my netbook that i am writing this from). i haven't spent a lot of time doing any troubleshooting with win7, so i am a little at a loss here. i rebooted the machine, tried disabling and re-enabling the wireless adapter, but it still just doesn't recognize any connections.

Any suggestions?

Thanks,
Drake

i can't imagine the wireless card just suddenly up & died, but i suppose it can happen.

its not picking up any wireless signals, and there are many to choose from in my neighborhood.

i have not tried updating the drivers (mainly b/c i hadn't yet wanted to deal with the pain of burning them to a disc from another machine), but i can try that.

i haven't tried wired connecting b/c my desktop is across the apartment from the router & modem.

let me try updating the drivers and doing the system restore and see what happens...
