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 No LSB modules are available.
