First of all I'm using Knoppix 3.4 booting from CD! (no HD inst.)
After unplug and plug etc. I got my DWL-122 to recognize and connect to the AP but I'm unable to set up the WEP encryption key.
wlcardconfig reports something like this function is not supported...

OK. The AP uses a 128bit ASCII WEP Encryption.
What commands do I have to type in

'cause I'm a noob to linux I would appreciate your help.

By the way...Is the recognition problem of a prism USB adapter in the actual version of Knoppix solved?
