There exists a Linux driver for your card at
http://acx100.sourceforge.net and lots of generic information on wireless networking with Linux
here. Note that the driver was a bit unstable the last time I used it (admittedly with a DWL-
G650+), on certain rare occasions it would even crash the whole system, and the project doesn't look terribly active.
An alternative would be to use the Windows driver with
NdisWrapper. I can't say much about it as I haven't used it myself.
In any case, if you need help installing one of these, please post your distribution along with detailed information on where you're stuck and, if applicable, exact error messages you see.
Good luck!
