I wasnt able to find a driver.
I did find an experimental am1771 driver from SMC at
http://www.emota.com.br/wireless/extra/
This should at least be tried.
This may be a longshot, but can try
http://ndiswrapper.sourceforge.net
this seems to have decent docs
from
http://lists.freebsd.org/pipermail/f...ry/001005.html
- AMD Am1771/Am1772 wireless LAN chipset. This one probably won't
work: the supplied AMD driver calls lots of functions in ntoskrnl.exe
which I haven't implemented yet. This chipset is present on the
SMC 2602w version 3 card. I repeat: that's the SMC 2602w VERSION THREE.
The version 1 card is a Prism chipset. I don't know what the v2 card is.
Another note, I was able to get more hits googling "am1772"
Hope this helps. If no luck at all then maybe try returning it.
