wpa_supplicant/TTLS/EAP-MD-5 on XP complains "NDIS: Couldnotfind interface ... "

Hi,

It turns out the Windows' version of wpa_supplicant needs to be executed in
cygwin shell. The interface initialization problem happens only if I launch
the supplicant from DOS shell.

I wonder if anyone why that's the case?

Hi Jouni,

Thanks for the feedback.  You were right that I was using an older winpcap.
But, the interface initialization problem appears to be persistingafter I
upgraded to WinPcap_3_1_beta4.exe.

The following supplicant output shows that wpa_supplicant is figuring out a
few more information before it stopped.  

Thanks for the help,

Wen

Which version of WinPcap are you using? Please re-test with 3.1 beta 4
unless you have already tested that.
