AVM USB Stick does not work

I have a problem :wink: I decided to use Linux and so I installed Susu 11.1 (well, I am not a real expert in Suse).
I have a Fritz USB stick and I followed the advices on that link:AVM Fritz!WLAN Stick USB unter openSUSE 11 einrichten - openSUSE
After I installed ndiswrapper and the driver windows driver, I checked it with the command ndiswrapper -l:
fwlan : driver installed …
But when I try do start a connection iwth KWiFi, i can not find any.
When I say: iwconfig
lo no wireless extensions
eth0 no wireless extensions

can anyone help me? I have no idea what to do :frowning:
