If its a wmp11 v2.5 and below, its just another prism2 card:
ifconfig ethX up
iwconfig ethX essid nameofnetwork
Might need to add an "iwconfig ethX enc 21321321" if you're running encryption.
If its the WMP11 v2.7, that's a broadcom card that is not currently covered by any linux drivers.
Get stuck, post back,
