This might help. I am not familiar with that model number. Is it usb or pcmcia?
If it uses prism54 drivers then check out
http://prism54.org . They are making big changes. They might be able to help you. Email them for help.
Here is a link on wg511 v2 I have done.
http://www.linuxquestions.org/questi...hreadid=295200
Post output of the followning commands. Requires root access?
/sbin/cardctl status
/sbin/cardctl ident
/sbin/cardctl info
If all else fails look into using ndiswrapper
Hope this helps.
