DWL-520+ will not ASSOCIATE

Been stuck for a while trying to install a DWL-520+. I
have Linux 2.4.21_0.13mdk and acx100_pci.o made
from code version 2003.11.16 -0.2.0pre6. I am trying
to persuade it to connect with a D-Link DSL-504 Router
through a 3Com Access point (WL-308). There is
already a wired connection with the router. The wireless
point and access card work OK in Windows.

The driver compiled nicely and the start_net script
seems to do its stuff except that the line trying to insert
into the routing table produces:

SIOCADDRT: File exists.

The big problem however is that the driver can not
associate. The warnings log shows that things are
rattling along nicely until it reaches iStatus = 3. The
next step is to try to associate and this fails eleven
times before it gives up. The LED on the card flashes at
each of these attempts so it looks as if it is really trying
to do something.

The startup script is using managed mode and the
ESSID is accepted as a match. ifconfig and iwconfig
give plausible results but, alas, still no association.

I am not sure if the SIOADDRT problem is connected to
the failure to associate but any useful pointers would
encourage me to keep trying.

The bit out of the warnings log where it hits the
problem and the details of ifconfig and iwconfig are
attached below.
