Unable to connect with WPA PEAP/MSCHAPv2 authentication

[C Michal]

After updating my mini-9 yesterday (April 16) I can no longer connect with WPA PEAP/MSCHAPv2 authentication.

Syslog shows:

nm-applet: Unhandled setting secret type (write) '801-1x/private key' : 'GArray_gu_char_'
nm-applet: Unhandled setting secret type (write) '801-1x/phase2-private-key' : 'GArray_gu_char_'
nm-applet: <WARN> constructor (): Invalid connection: 'NMSettingConnection' / 'type' invalid 3

and /var/log/wpasupplicant.log shows:
Association request to the driver failed

a little googling shows similar problems here:

does it work if you create a new connection configuration?

[Alexander Sack (asac)]

also, assuming your setup wasn't a system connection, please attach gconftool-2 -R /system/networking

Oh. one obvious thing. which networkmanager did you use before and which version are you using now? (e.g. from where to where did you upgrade).

I went from network-manager-0.6.6-0ubuntu5_lpia to
network-manager-0.7~~svn20081018t105879+mbm.f2-0ubuntu1-hardy5

If I try to create a new connection configuration with network-manager, there is no option for WPA enterprise, the only security options are None, WEP40/128-bit key, WEP 128-bit Passphrase, and WPA&WPA2 Personal.

My previous set-up was always managed by network-manager. gconftool-2 -R /system/networking returns nothing.

Strangely, I can't seem to downgrade network-manager-gnome. Synaptic complains that I'm trying to install broken packages...

ok, a little more searching, and I found this:

https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/284211

which has some instructions on editing the connection profiles that network-manager (-gnome?) creates. I removed a wep40, wep104, and ccmp from the group field, and a ccmp from the pairwise field, and now it connects fine.

Canonical QA is unable to test this bug as we do not have the appropriate network configuration. Marking as confirmed to be looked at by the engineers.
