Servus, liebe Netzwerk-Götter!
Seit einigen Tagen lassen sich die (leider) üblichen, aber unregelmäßigen Verbindungsabbrüche nicht durch ein Ein- und Ausschalten der Hardware richten. Das Network Manager-Applet von KDE bleibt in diesem Fall schlicht blank, es wird nicht eines der deutzenden Netzwerke um mich herum mehr angzeigt. Nach einem Neustart ist alles in Butter. rsyslog hängt an. uname -a

Einige Angaben habe ich im Gedanken weggelassen, dass der Fehler am laptop und nicht im Wifi-Netz liegt, da im problemfall ja keines mehr erkannt wird. Falls vor Kurzem erst ein ähnlicher Fehler behandelt wurde, einfach darauf verweisen - ich habe auf die Schnelle keinen entdecken können. Einen schönen Abend noch!

[ 709.557910] wlan0: deauthenticating from 02:26:4d:ac:8f:45 by local choice (Reason: 3=DEAUTH_LEAVING) Offenbar ein Netzwerkmanager-Problem. Teste Wicd mit Add-On: wget http://www.elektronenblitz63.de/download/wicd-1.6.x_addon01441.tar.gz
sudo apt-get install --reinstall wicd
tar xvf wicd-1.6.x_addon01441.tar.gz
cd wicd-1.6.x_addon01441
sudo ./install_wicd_addon
sudo service network-manager stop
sudo killall wpa_supplicant
sudo service wicd restart Wähle als Schnittstelle wlan0 und als Treiber wext. Die Konfigurationsdatei kann weg, der Treiber ist iwl3945:
sudo rm /etc/modprobe.d/iwlwifi.conf Welche Verschlüsselung wird verwendet?

WICD mag ich eigentlich nicht so, da es wie ein Fremdkörper wirkt. Trotzdem versuche ich es einmal. Danke für die schnelle Antwort. Verwendet wird ausschließlich WPA2 PSK. Aber wie gesagt - solange kein Netzwerk im Netzwerk-Manager auftaucht, nicht einmal die unverschlüsselten, sollte (tm) es daran nicht liegen.

In der Tat kann ich bei erneuten Problemen einfach den network-manager und wpa-supplicant abschießen und WICD starten, um weiter im Netz arbeiten zu können. Danke. Morgen öffne ich mal einen Bugreport.
Die Konfigurationsdatei kann weg, der Treiber ist iwl3945.
KLingt logisch. 😀 Danke.

Hallo,
das Problem dürfte unabhängig vom verwendeten Netzwerk-Manager auftreten, da es sich ja anscheinend um einen Firmwarefehler handelt.

Ich zweifele die Analyse nicht an, aber es interessiert mit, weshalb dann teilweise WICD noch funktioniert, nachdem der Network Manager streikt.
Du startest das System nicht zufällig aus dem Standby/Ruhezustand?
Sehr oft. Der Fehler tritt allerdings erst einige Zeit, teilweise Stunden später auf, selten direkt danach. Also bleibt abzuwarten, bis die Sache im Kernel gerichtet wurde. Gegen welches Paket soll ich den Fehler melden? Linux-Firmware?

Hallo,
teste dennoch versuchsweise mal pm-utils (Abschnitt „Module-vor-SUSPEND-entladen-nach-RESUME-wieder-laden“) -„Module vor SUSPEND entladen nach RESUME wieder laden" echo -e 'SUSPEND_MODULES="$SUSPEND_MODULES iwl3945"\n/sbin/ifconfig wlan0 up\nservice wicd restart' | sudo tee /etc/pm/config.d/00sleep_module
Dann noch ausführbar machen:
sudo chmod +x /etc/pm/config.d/00sleep_module
Standby und Funktion testen. Einstellung der Karte?
iwconfig wlan0
iw reg get
Wie hoch ist die Sendeleistung? In letzter Zeit gab es öfters Probleme mit überhitzten Chipsätzen, auch bei Intel und in Verbindung mit Ubuntu 14.10.

Welchen WLAN-Router benutzt Du und seit wann? Wie sind auf deinem Laptop die Ausgaben von:
lsmod | grep -i iwl
cat /var/log/syslog | grep -i deauth
sudo tcpdump -c 300 -vvveni any arp
? EDIT: Hattest Du die "üblichen, aber unregelmäßigen Verbindungsabbrüche", mit deinem Laptop auch mit anderen Ubuntu-Versionen?

Hattest Du die "üblichen, aber unregelmäßigen Verbindungsabbrüche", mit deinem Laptop auch mit anderen Ubuntu-Versionen?
Ja, eigentlich seit ich das Gerät habe. Und mit dem Vorgängergerät, gleiche Hardware, gleiches Modell, gleiche Wifi-Karte. Das Wlan einmal entladen und wieder laden, oder den Hardware-Switch bedienen löste das Problem immer schnell. Hute morgen hat sich das T500 einmal komplett aufgehängt.

Diese Probleme (d. h.: "deauthenticating from ...") hatte ich auch mit meinem:
:~$ lspci -nnk | grep -i net -A2
03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4227] (rev 02)
Subsystem: Intel Corporation ThinkPad R60e/X60s [8086:1011]
Kernel driver in use: iwl3945
Als workaround benutze ich:
einen statischen arp-Cache-Eintrag für den Router und
mit cron, ein Script mit arping, das alle 3 Minuten einen arp-request (wenn beantwortet wird) für den Router sendet und zusätzlich 2 "Gratuitous ARP" (das sind arp-replys) für den Laptop, in das WLAN sendet.
