I have managed to the my D-Link DWL-650 working OK with the wvlan_cs driver.But I find reference to a samsung driver that is also available and support the WEP encryption (for what it's worth).
I tried following some instruction on setting up the driver. I compiled it. put it in /lib/modules/2.4.9/pcmcia ran 'depmod -a' added a reference in /etc/pcmcia/config for the driver and it doesn't work. It keeps loading the wvlan driver instead. Any suggestions?
