iwl3945 dropping from network

iwl3945 dropping from network

[Kalle Valo]

Good morning,

during the weekend I have noticed that my iwl3945 is dropping from
network and wpa_supplicant can't connect to the network anymore, only
'wpa_action wlan0 stop' (which essentially quits wpa_supplicant) and
'ifup wlan0' (which starts wpa_supplicant, debian is weird here) makes
it work again. I think I'm seeing similar behaviour also when I resume.

I'm using debian unstable on Lenovo x60s with wpa_supplicant 0.6.9-3, so
the old wext interface is used. wpa_supplicant isn't updated since May
which points that this a problem in the wireless-testing kernel.

Here's one log from a situation when the connection suddenly dropped:

I started seeing the exact same thing last friday with my 5100. In my
setup I am using networkmanager and it did not give me much debug
information when the problem occurred. I had to restart networkmanager
to be able to connect again. My logs look the same as yours though. I am
now running with wpa_supplicant in foreground with full debugging but so
far it has not happened yet.
