I believe that this card has the Ralink chipset... If so, you need to get the rt2500 or rt2400 driver. Hope this helps. If you can't get the driver working, post back and I'll walk you through installing the Windoze driver with NDISWrapper.
My only problem was the sound card. I got this to work under DreamLinux using the Asla 1.0.14. When I tried to replace Alsa 1.0.13 in Elive Synaptic wanted to remove most of the packages so I did not go ahead.
