Since DHCP was also failing, this could also be triggered with something
going wrong in key configuration. I've seen ethereal showing "LLC
headers" with madwifi under Linux when the group key was being
configured without group key flag. Anyway, it looks like you are already
aware of some changes needed to the ethereal/kernel, so that could of
course also explain this.

I'm not particularly interested in driver specific issue under any OS
;-) if it is clear that the authentication part itself worked correctly.
