What AP (model & firmware version) is this?

Configuring CA certificate is highly recommended for PEAP, even though
this kind of configuration should work. Without CA configuration, the
authentication is open for man-in-the-middle attacks.

OK, AP scanning seems to be working.

However, IEEE 802.11 association did not succeed in five seconds.

This can be increased, but five seconds should be enough time for
association.. If you like to test this, you would need to change the
following call in wpa_supplicant_associate() function of
/* Timeout for IEEE 802.11 authentication and association */
wpa_supplicant_req_auth_timeout(wpa_s, 5, 0);
The second parameter (5) is number of seconds that the association is
allowed to take.

IEEE 802.11 association seems to be failing for some reason. The best
way for debugging this would be to use a wireless sniffer to verify
whether the client is sending out association request. Since ndiswrapper
has been successfully used with a Broadcom card and wpa_supplicant, I
would also consider testing with another NDIS driver. Please also let me
know which NDIS driver you are using (URL for a download site would be
useful) and which ndiswrapper version you have tested.
