I guess that leaves us with the possibility my AP is not sending some packets (see Larry's message about that) during the association, which makes the driver not work as it should... Is there anything else I can try to help you guys figure out what may be wrong? Stefan Zwanenburg PS: I'll keep running this kernel for a few days to see if I get the same problem as in mentioned in the discussion "3.1-rc6 + rtl8192se issue", even though I apparently don't have the very latest kernel source.
