Hi,

 

I have not been able to go very far with wpa_supplicant on XP.
Ndis_events.exe was running when I started wpa_supplicant.  And, my
supplicant stopped at "NDIS: Could not find interface .".  I have included
with this email the conf file, win_if_list output, wpa_supplicant output and
some system settings.  I'd appreciate some advice.

 

Thanks in advance, - Wen

 

Basic Configuration:

~~~~~~~~~~~~~~~

Host Configuration: Windows XP Pro SP2, Thinkpad 41, IPW 2100 card

wpa_supplicant: from wpa_supplicant-windows-bin-0.3.8.zip

similar result)
