I am in need of a usb 802.11 network adapter that likes Linux. I bought a 
D-Link DWL-120 (may return to BestBuy) and have yet to make it work. The 
only thing I have found on the internet in regards to a driver that might 
work is the pegasus driver. However it is for 10/100 baseT. I haven't 
"really" tried to make it work yet. I have not found any Hardware 
Compatability lists that even speak of such a device.
Has anyone played with 802.11/USB devices under Linux? I found a couple of 
projects on freshmeat that look promising. Maybe I'm better off just 
getting pci cards.(but I don't want to).
