My first guess is that you have not installed the chipset drivers for your motherboard for Vista. Without them the wifi driver will not be able to communicate with the wifi device through the motherboard.

Check your device manager. Right click My Computer - Manage computer - device manager. If you see any yellow symbols on the devices, then it is most likely missing a driver. If you have your laptop/pc model. You can go to the site for support and download the latest drivers (which you should do for all devices anyway) and install those.
