Hi folks,

I installed on my SuSE 9.0 laptop the experimental driver (acx100) for
the WLAN card DWL 650+ by D-Link. The card seems recognised (iwconfig
dixit) and the logs indicate that the DHCP server I'm trying to connect
to is found and the association request is accepted. I still don't
have access to the network, though (1).

I have no idea, whether it's a hardware or software problem... you
can find the details below:

Any ideas?
