Bug Description

Binary package hint: network-manager

I upgraded from 9.04 to 9.10 and my wireless connection stopped working.

Disabling NetworkManager the connection works again.

My wifi connection is not protected but it filters MACs.

The problem is in the way NetworkManager uses wpa_supplicant.

I loaded iwlagn with debug=65535 and this is the output of /var/log/syslog

Nov 6 20:42:49 Mobiligor4 kernel: [ 36.193582] wlan0: authenticate with AP 00:18:f8:xx:xx:xx

Nov 6 20:42:49 Mobiligor4 wpa_supplicant[741]: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

I must add that I have a /etc/wpa_supplicant.conf with one network of type WPA-PSK

It took some time to pin down the problem because
1) if the interface wlan0 was down and I configured the essid for wlan0 manually with iwconfig the essid was accepted (as it could be verified by iwconfig) but the essid was lost as soon as I brought the interface up

2) if the interface wlan0 was up and I tried to configure its essid with iwconfig wlan0 simply did not accept the essid and iwconfig showed no essid assigned to wlan0.

Does "iwconfig wlan0 power off" fix the problem (until reboot)?
