I am not at home to check, but WPA using PSK requires wpa_supplicant
and a very simple config file with your SSID and PSK (either text
string or numeric string). These setups are detailed on the ndiswrapper
site. See the WPA wiki for simple setup instructions:
http://ndiswrapper.sourceforge.net/phpwiki/index.php/WPA?PHPSESSID=792d7561f3d3a2741e9928e3fde4bcc6
I hope this helps.
Donn, what do your configuration files looks like with WPA enabled? I
haven't found (haven't looked very hard though) documentation for those
files yet.
