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 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.

Interessting, acording to some helpers, are the following lines:
dmesg: wlan0: deauthenticating from 02:26:4d:ac:8f:45 by local choice (Reason: 3=DEAUTH_LEAVING)
