I don't know what ndiswrapper is, would you mind doing a step by step on how to set that up?

I downloaded the XP driver from the website, and it came in an .exe that wanted to run the setup wizard for the wireless card.

I'm having the same problem, and tried mfillpot's fix by downloading and attempting to install the XP driver, but it doesn't appear to work. It tries to run the wizard, and is unsuccessful. It is unable to load. Any ideas on how to fix that?
