I have had this issue for a while and have spent quite a bit of time debugging this problem. Here's my progress so far:
Problem: The wpa_supplicant included with Ubuntu is too old, doesn't support EAP-FAST
Proof: From syslog
NetworkManager[1252]: <warn> EAP-FAST is not supported by the supplicant
Solution:
12.10 didn't upgrade the wpa_supplicant version, so I was left to compiling it myself. After a few attempts I could successfully compile the code, downloaded from this location. I then replaced the default version of wpa_supplicant manually (copied it to /sbin, luckily after having backed up the existing executable)
Complications:
- Turns out, the new wpa_supplicant doesn't play well with the older parameters. During startup, the wpa_supplicant is called as a dbus service. The exact call is stored at /usr/share/dbus-1/system-services/fi.w1.wpa_supplicant1.service. This call fails as the older parameters passed to the wpa_supplicant no longer work. This, in turn, leaves the network manager completely unusable.
- You can manually call the new wpa_supplicant with your own configuration and it does work properly, but network manager integration is missing in this scenario.
- I would greatly appreciate further suggestions.
