wpa_supplicant fails with ndiswrapper andmadwifi driver for Atheros 802.11a/b/g card

[Michael Reilly]

Just a quick follow up.  I tried an 802.11a access point last night (D-Link 
DWL-7100AP).  Same problem.  Atheros based cards do not work using 
ndiswrapper and WPA-PSK (wpa_supplicant).  Didn't try madwifi last night but 
it hasn't worked in past tests so I expect it fail with this AP also.

Driverloader works fine using the same wireless card drivers, same 
wpa_supplicant with same wpa_supplicant config file.  Only change was to 
specify ndiswrapper driver vs hostap driver (-Dndiswrapper vs -Dhostap).

Anyone have any ideas how to debug this?
