I recently converted from RedHat 9.0 to SuSE 9.0, and am trying to figure
out how to get my wireless card to work.

It is based on the ADMTek 8211 chip set and worked flawlessly in RedHat.

ADMTek has a driver on their Web site that needs to be compiled and copied
into the right place for the modules. I used the same driver under RH 9.0
with the 2.4.20 kernel without a problem.

The compile went fairly smoothly. The driver is intended for any 2.4
kernel, nothing RH specific to my knowledge.

In SuSE, however, I have quite a few individual problems:

- YaST creates a device wlan0 for this driver. When I later try "ifup
wlan0" I get an error message "Could not get a valid interface name: ->
skipped." iwconfig, meanwhile, sees the card as eth1. So what gives? Is
this card supposed to be under eth1? But then YaST does not allow me to
set any wireless options. Manually changing modules.conf, and renaming
/etc/sysconfig/network/ifcfg-wlan0 to ifcfg-eth1 resolves this problem.
But that is probably not the proper solution, since YaST insists on the
wlan0 name.

- after this hack, ifup eth1 will return an error message "Could not set
encryption, device does not support it". Under RH, encryption worked just
fine.

- most iwconfig commands do not do anything. The only thing I can
successfully set is the encryption key and the mode. Setting essid and
channel reports success but does not do anything. Setting AP or calling
commit fails with an error message.

Thanks!
