Sorry for the delay in responding - I was out of town for a few days.

The driver provided by Cisco with the card.  From the log-

	 ndiswrapper: driver net21 (,08/27/2004,1.2.0.3) 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 (,12/03/2003,2.4.2.33) 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.)
