Mandriva 2008 immediately switches back to WEP instead of WPA
I have recently installed Mandriva 2008. It identifies my wifi-adaptor correctly, and it shows my wireless network in the list.
I don't manage to get a connection, though. The network uses WPA. I tried to configure Mandriva to use WPA, but when I reopen the configure window, after closing it with the OK-button, it says WEP again.
I installed the windows driver with ndiswrapper instead of de linux driver. I followed the steps in this tutorial: How to get Ndiswrapper with wpa_supplicant working - LinuxQuestions.org
With the step
It failed. A lot of "opperation not supported" errors and some other text.
wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -Dwext -w
I don't know how to fix it. Please help me!
