WPA-PSK w/ ndiswrapper
 

Ok, I've got a wireless network set up at home w/ WPA-PSK enabled. The broadcom driver will allow WPA-PSK to work in windows, so theoretically it should work under ndiswrapper right? How do I enable WPA-PSK?

In addition to the driver, you need something called a supplicant to handle the authentication part of WPA. Windows now includes a supplicant with XP. (For earlier Windows versions, 802.1x authentication requires a commercial solution).

Try wpa_supplicant: http://hostap.epitest.fi/wpa_supplicant/
