The driver provided by Cisco with the card. From the log-
ndiswrapper: driver net21 (,08/27/2004,126.96.36.199) added
I tried with a Linksys WPC55AG card last night (also Atheros based). Same
failure. The Linksys card also works fine with driverloader.
The Linksys driver -
ndiswrapper: driver ar5211.sys (,12/03/2003,188.8.131.52) added

Yes to both. I also tried a WRT54GS last night and neither card worked with
ndiswrapper but both work fine with driverloader.

Something seems to have broken since you tested it. I have the same failure
with ndiswrapper 0.10 and 0.11 so it has been broken at least that long.
(Re-tested both last night.)
