I don't know about your card's compatibility (we would need exact make and model to check on that), but assuming it uses the Prisim 2 driver it should work. It's just a 802.11b card right? Not 11a or 11g? What is the output of lsmod? Try wlcardconfig. iwconfig will work, but if you're a newbie, you'll find wlcardconfig much easier.
