Kein WLAN nach dist-upgrade auf 15.10

**rstuby** · 24.10.15, 12:20

Hi!
Ich habe gleich am 22. mit meinem Tablet ein Upgrade auf Lubuntu 15.10 gemacht.
Jetzt bekomme ich keine WLAN-Verbindung mehr.
Das Notebook verbindet sich mit demselben WLAN weiterhin problemlos. Sonst würde ich direkt sagen, es läge am Router, denn die Verbindung wird angezeigt mit Signalstärke und allem, kommt aber nicht zustande. Entweder der Ladekringel wird einfach wieder durch das "nicht verbunden"-Symbol ersetzt, oder aber es kommt eine erneute Passwortabfrage.

Wie kann ich denn, wenn Networkmanager läuft, auf der Konsole die Verbindung herstellen, so dass man sehen kann, welche Fehlermeldungen es gibt? Oder welche Logs und Ausgaben könnten hilfreich sein? Meiner Ansicht nach sieht iwconfig und iwlist scan normal aus und dmesg auch, aber wenn ihr es sagt, werde ich es auch abtippen, per Stick rüberkopieren oder kurz mit mobilem Internet online gehen, um die Sachen zu posten.

Normal würde ich ja sagen, warten wir erst mal ein paar Updates ab...
Aber die alle mit mobilem Internet zu machen wird etwas teuer. Einen Kabelanschluss hat mein Tablet nicht.
Am Montag versuche ich noch mal, mich im Büro in ein anderes WLAN einzuwählen, und teile dann mit, ob das geht.

UPD: Eine saubere Neuinstallation wollte ich EIGENTLICH erst machen, wenn X... X... rauskommt.

Der Networkmanager loggt doch alles mit:

journalctl -b -t NetworkManager

Ist ja super! Das sieht bei mir so aus:

Ich kann aber noch nicht einmal herausfinden, was reason -3 heißt, und irgendwie sieht es mir nach einem Bug aus. Ich mache mir jetzt mal einen Livestick mit dem System und melde mich wieder.

Also, vom Stick mit http://cdimage.ubuntu.com/lubuntu/re...ktop-amd64.iso ist es noch schlimmer. Da wird gar kein WLAN angezeigt. Dann mache ich damit zumindest schon mal keine Neuinstallation.

Dann probier mal folgendes: schalte den NetworkManager komplett aus, leg dir eine /etc/wpa_supplicant.conf an, in die du dein Netzwerk einträgst, und dann rufst du auf:

Code:

sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf

Dessen Ausgabe wird dann interessant.

**rstuby** · 24.10.15, 20:05

Hoffentlich habe ich alles richtig gemacht!

Code:

Successfully inizialized wpa_supplicant
nl80211: Driver does not support authentication/association or connect commands
nl80211: deinit ifname=wlan0 disable_11b_rates=0
wlan0: Failed to initialize driver interface

Update: Gerade mit einem anderen WLAN erfolgreich verbunden. Mache gerade Updates und dann nachher mal sehen, ob es zu Hause auch läuft.

**rstuby** · 26.10.15, 14:39

Zu Hause geht es immer noch nicht. Der Provider ist der gleiche und auch die Router sind ähnlich, aber zu Hause ist eine Positivliste von MAC-Adressen eingerichtet. Kann sich durch das Update die MAC-Adresse von meinem Gerät geändert haben? Doch wohl nicht, oder?

**ThorstenHirsch** · 26.10.15, 20:00

Eigentlich hätte ich nein gesagt, aber viele WLAN-Treiber bestehen zum Teil aus einer Firmware und seitdem ich mal mit dem Aufspielen einer neuen Firmware die USB-ID eines DVB-T-Sticks geändert habe, halte ich sehr vieles für möglich mit so einer neuen Firmware (die sich ja von 15.04 auf 15.10 durchaus geändert haben kann). Ungewöhnlich wär's natürlich trotzdem. Aber ich hab' auch keine Idee mehr, warum die Verbindung plötzlich nicht mehr funktioniert.

Testweise ausschalten? Oder Router neustarten. Soll Wunder wirken.

Wohl eher nicht. Aber prüfen kannst Du das selber.

Danke für die Tipps, habe ich gerade beides versucht. Aber auch mit neugestartetem Router und ausgeschaltetem MAC-Filter verbindet er nicht. Laut ifconfig ist die MAC-Adresse richtig.

Aber da ich ja jetzt im Büro Updates einspielen kann, sehe ich das nicht mehr so kritisch. Ich vermute, irgendwann läuft es wieder.

Also inzwischen hat es ja schon Updates für NetworkManager, Kernel, Firmware und wpa-supplicant gegeben und trotzdem bekommt das Tablet zu Hause kein WLAN, sondern tut so, als würde das Passwort nicht stimmen (auch mehrfach neu eingegeben).

Jetzt habe ich mich daran erinnert, dass auf meinem Notebook und früher auch auf besagtem Tablet immer die Meldung kommt:

Code:

“Network service discovery disabled. Your current network has a .local domain, which is not recommended and incompatible with the Avahi network service discovery. The service has been disabled.”

Was bedeutet das? Wo ist diese .local-Domain definiert, auf dem Router? Könnte es sein, dass etwas, was schon jahrelang eine Warnung verursacht hat, nunmehr einfach gar nicht mehr unterstützt wird?
Kann man das mit der .local-Domain ändern (wenn ich z.B. den Admin frage)?

**ThorstenHirsch** · 07.12.15, 22:43

Das ist nur eine Meldung von Avahi, einem Bonjour/Zeroconf-Daemon. Das ist so etwas wie eine Auto-Erkennung von Netzwerkgeräten. Aber es hat keinen Einfluss darauf, ob die WLAN-Verbindung zustande kommt oder nicht. Und auch das, was avahi als Grund aufführt, weshalb es nicht starten will (.local domain) kann sich nur negativ auswirken, wenn du im Netz bist, aber es kann nicht den Aufbau der Netzwerkverbindung beeinflussen.
