I just reinstall a new windows xp on a friend's laptop after her last OS was damaged when an anti-spyware/virus deleted a system file in a scan. The problem is that the product-key under her laptop wasn't working when it tried to verify it. I used a makeshift one that was old so I can later on change the product key and do a genuine verification online. Here is the problem. Her wireless adapter was not visible on device manager or control panel. Is there a starting point where I can find the solution to this problem?
