Title:
[Kubuntu 14.04 and 14.10] Network manager stops working: iwl3945
0000:03:00.0: BSM uCode verification failed at addr ...; wlan0:
deauthenticating from... by local choice (Reason: 3=DEAUTH_LEAVING),
Status in linux-firmware package in Ubuntu:
Confirmed
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
From time to time, the system loses all wireles networks and kubuntu
network manager applet goes blank - not even one network is shown. All
wifi connections are broken. Rebooting fixes the issue, switching to
WICD on-the-fly enables to continue browsing without rebooting, so it
seems to be no hardware issue or iwl3945 issue.
What to expect: stable connections and flawless network managing.
What happens: so above.
Further informations about the system, the network configuration, the
package version can be found in the attachment, also parts of rsyslog
and dmesg.
Interesting, according to some helpers, are the following lines:
dmesg: wlan0: deauthenticating from 02:26:4d:ac:8f:45 by local choice (Reason: 3=DEAUTH_LEAVING)
lsb_release -a
