Vista - Windows Cannot Find Any Networks

I've just formatted my desktop PC and reinstalled Vista but now I can't update drivers because I haven't got the drivers for my network card. I'm connected directly via ethernet cable to my router but it still doesn't see any networks. What can I do?

If you cannot get online to get the necessary drivers. Go to the website using a friends or even an enemys computer. Donwload the driver to thumb drive and then install from the thumb drive.

Thanks i'll give it a try.
