Reformatted a computer, and now...

[Blitz]

I have no wireless.

I have this old laptop that I wanted to completely reformat and reinstall Windows on. I didn't have the original disc, so I downloaded XP to put on it (whether that could contribute to the issue, I dunno).

So I reformatted and reinstalled and it all went swimmingly. But there is no icon for the wireless network in my Network Connections. I go to devices and there's no wireless card listed, even when I click hidden devices. It's as if it's gone from the computer, but it's not, because it had wireless before I reinstalled everything.

Only thing I can think of is that the laptop had taken to running really hot, so maybe the card got fried? But even that doesn't make sense, because the wireless was working before I reinstalled. I dunno if it's a driver issue or what. But I can't find out because I can't even find the card.

Help?
