FYI, I've got this kinda working with wpa_supplicant in wext mode.

First: on it's own wpa_supplicant keeps doing the 4 way handshake, while
 cfg80211 pumps out the following:

Cfg80211 is trying to select the bss we've authenticated against.
Unfortunately the BSS list is empty.

If before starting wpa_supplicant I run:

iw dev eth1 scan ssid <SSID>

Then wpa_supplicant connects fine. The AP in question is configured with
a hidden SSID.

Any suggestions as to how I need to address this?


Regards,

Dave.
