I'm using an iwl3945 wireless network card, that was working like a
charm with Intrepid. Now, after upgrade to Jaunty, I have many
disconnections of wireless connection : NetworkManager seems to
disassociate the SSID by choice. This is a WPA EAP-TLS network. I
haven't been experiencing this kind of behavior on a clear wireless ssid
(at school).
Once NetworkManager has lost the connection, it will retry several times
to reassociate with the access point, often failing for around 5
minutes. Thus, it also regularly asks for the EAP-TLS configuration that
it already has (just need to revalidate).
Just killing and restarting NetworkManager allows for a faster
reconnection process : as soon as NetworkManager gets restarted, it
associates in a couple of seconds to the access point.
Disconnections seems to occurs on a more-or-less regular time base : I
experience disconnection each 3800-4000 secs. Roughly every hour.
I checked using Jaunty LiveCD, and I still experience the issue, on the
same time base. I already tried the linux-backports-modules-jaunty. No
success. I even tried to upgrade iwl3945 firmware with latest available
from http://intellinuxwireless.org, and no change. I also tried to
switch on the 'proposed' repos, upgrade everything that was available
(there were kernel updates inside), rebooted and still no evolution.
This behavior is *really* annoying.

+ NB: Check comments, I was wrongt about NM, it's lying in WPA Supplicant.
