Martin,
Have a look at this which should help you:

>From memory with WEP don't use wpa_supplicant for these but use Linux
kernel directly. The reason for this is the bugs in the 2100 code.
2200 has similar issues that were reported to the list. With the
latest Linux kernels you only need wpa_supplicant for WPA and Jouni is
helping migrate more of that into the kernel as well - hopefully we
are not too far away from where WPA just works - Linus has said it is
one of his main goals to get working also.
The parent URL also has lots of useful info:
