Hallo alle,

auf meinem ThinkPad habe ich sowohl Windows 7 als auch Ubuntu installiert und habe unter Ubuntu massive Verbindungsprobleme mit dem eduroam der TU Berlin. Unter Windows läuft das eduroam einwandfrei und unter Ubuntu hatte ich bis jetzt auch keine Probleme mit anderen Netzwerken. Wenn ich mit dem eduroam ins Internet will, zeigt der Network-Manager eine Verbindung an, aber Firefox kann keine Seiten laden. Das eduroam habe ich eingerichtet wie hier beschrieben: https://www.tubit.tu-berlin.de/wlan/zugang_und_anleitungen/eduroam_mit_linux_gnome/

Sehr sporadisch funktioniert es auch, an der eduroam-Konfiguration kann es also eigentlich nicht liegen.

Hier erstmal ein paar Terminal-Ausgaben:

Hier hat der Router beim Pingen nicht geantwortet, es kam aber auch schon vor, dass der Router geantwortet hat und das Problem trotzdem auftrat.

Letztens habe ich den Network-Manager deinstalliert und mein Glück mit wicd versucht, aber das hat nicht geholfen.

Außerdem habe ich versucht, im Network-Manager eine konkrete BSSID anzugeben, da es anscheinend mehrere eduroams mit gleicher SSID gibt, aber das hat auch nichts gebracht.

Vielleicht kann jemand mit den Ausgaben etwas anfangen und hat eine Idee, was ich noch versuchen kann?

Beste Grüße

Judith

Hallo und willkommen bei uu.de.

Viele gleichnamige Netze wie "eduroam" verwirren den Networkmanager beim Neuverbinden. Gib die MAC-Adresse des nächstgelegenen AP im Feld BSSID an.

Hi praseodym,

danke für den Willkommens-Gruß und die Antwort.

Wie schon gesagt, ich habe bereits probiert, eine BSSID im Network-Manager einzugeben, das hat aber nicht geholfen. Was genau meinst du mit 'nächstgelegener AP'? Ich hatte die MAC-Adresse des AP angegeben, bei dem der Quality-Wert am höchsten war. Als das nicht funktioniert hat, habe ich auch noch ein paar andere ausprobiert, aber das Problem bestand trotzdem weiterhin.

Hast du noch eine andere Idee, woran das liegen könnte?

Deaktiviere die Warteschlange des Treibermoduls:

echo "options iwlwifi wd_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

Hallo,

das hat leider auch nicht geholfen.

Bei

echo "options iwlwifi wd_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf

kam

options iwlwifi wd_disable=1

als Output, bei

sudo modprobe -rfv iwlwifi

war der Output

modprobe: FATAL: Module iwlwifi is in use.

Hab dann geguckt, welches Modul iwlwifi benutzt und das dann versucht zu entladen:

sudo modprobe -rfv iwldvm

Als Output kam

rmmod iwldvm

rmmod mac80211

rmmod iwlwifi

rmmod cfg80211

Danach hat auch

sudo modprobe -rfv iwlwifi

sudo modprobe -v iwlwifi

keine Fehler mehr gemeldet.

Aber dann konnte gar keine Verbundung mehr mit dem eduroam hergestellt werden. Woran kann das liegen?

Hallo,

nicht wirklich. Im gezeigten Logauszug wird in kürzester Zeit eine Verbindung zu mindesten vier verschiedenen Accespoints aufgebaut. Das funktioniert natürlich nicht.

Lege für die jeweils verwendeten Standorte ein eigenes Verbindungsprofil an (z.B. Hörsaal XY, Mensa, Bibliothek usw.) und trage manuell die MAC-Adresse (BSSID) des empfangsstärksten Accesspoint an diesem Standort für dieses Profil ein. Damit wird Roaming zwischen den in Reichweite befindlichen AP mit identischer ESSID vermieden.

Den Originalzustand der /etc/modprobe.d/iwlwifi.conf wiederherstellen:

echo -e "# /etc/modprobe.d/iwlwifi.conf\n# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the\n# microcode file installed on the system. When removing iwlwifi, first\n# remove the iwl?vm module and then iwlwifi.\nremove iwlwifi \ \r(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \ \r&& /sbin/modprobe -r mac80211" | sudo tee /etc/modprobe.d/iwlwifi.conf

(das ist eine lange zusammenhängende Befehlszeile)

Kontrolle:

cat /etc/modprobe.d/iwlwifi.conf

Die Option wd_disable schaltet die Eigenüberwachung des Chipsatz ab (Watchdog), was hier vermutlich Probleme mit der Firmware im Zusammenhang mit der überschriebenen Konfigurationsdatei dann nicht behebt, falls Fehler auftreten. Kein Reload der FW:

Hallo,

ich hatte die BSSID dann wieder rausgenommen, als das nicht geholfen hatte. Jetzt habe ich nochmal die BSSID des AP eingetragen, bei dem der Quality-Wert am höchsten ist (69/79 war's gerade), aber nach wie vor keine Änderung.

echo -e "# /etc/modprobe.d/iwlwifi.conf\n# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the\n# microcode file installed on the system.

liefert

Rebootest Du den Rechner direkt aus Windows heraus?

Nein, ich fahre den Rechner runter und starte dann Ubuntu.

Habt ihr noch mehr Vorschläge?

Vielen Dank für die ganze Hilfe, ich wäre wirklich erleichtert, wenn das bald mal laufen würde.

Hallo,
die Firmware wird dann ja im dritten Versuch geladen, möglicherweise braucht die Karte etwas länger für den Startup-Vorgang. Die Rekonfiguration der iwlwifi.conf und Rücknahme der Moduloption sorgt für einen Restart der Firmware, sollte dieser Fehler im laufenden Betrieb auftreten.

Das aktuelle Verbindungsproblem mit dem AP ...

[  270.559416] wlan0: a0:cf:5b:3d:7c:ef denied association (code=17)

... beruht anscheinend auf einer fehlerhaften Athentifizierung (fehlerhafter Handshake). Der AP verweigert die Verbindung. Da stimmt möglicherweise etwas mit den Zugangsdaten oder der Konfiguration des Verbindungsprofils des Network-Manager nicht.

Nachtrag: dies scheint neben den ständigen Wechseln des AP die eigentliche Ursache zu sein. Beim AP a0:cf:5b:3f:a5:9f wurde eine Verbindung hergestellt. Der Logauszug endete dann allerdings, so dass die weiteren Ereignisse nicht erkennbar sind.

Hallo,

aber mit dem AP a0:cf:5b:3d:7c:ef wird doch dann auch irgendwann eine Verbindung hergestellt, oder nicht?

Sehr selten funktioniert es ja auch, daher kann es eigentlich nicht an der Konfiguration des Netzwerk-Profils liegen, oder?

Mir ist übrigens auch aufgefallen, dass es oft direkt nach dem Hochfahren kurz funktioniert, ich kann meistens eine Seite laden und dann ist es vorbei. Das kann aber auch Zufall sein.

Habt ihr noch Vorschläge, was ich probieren kann? Ich hatte jetzt immer den empfangsstärksten AP eingetragen, aber es funktioniert trotzdem nicht.

Ja, in diesem Moment hat es geklappt:

Es folgt dann die Zuweisung einer IP-Adresse über DHCP, ob das funktioniert ist nicht erkennbar.

Was zeigt

iwconfig wlan0

Hallo,

wenn der Network-Manager eine Verbindung anzeigt, aber keine Internetseite geladen werden kann, zeigt

iwconfig wlan0

folgendes:

Der AP A0:CF:5B:3D:7C:EF ist momentan als BSSID im Network-Manager eingetragen. Gestern habe ich es noch mit zwei anderen APs versucht, da hat der Network-Manager dann aber keine Verbindung angezeigt.

Versuche es mal mit Wicd & AddOn

Mit wicd habe ich es vor ein paar Wochen mal versucht, das hat auch nicht funktioniert.

Im Terminal kam immer eine Warnung, etwas mit "Source ID was not found when attempting to remove it", ist dir der Fehler bekannt?

Aber damals hatte ich auch das AddOn nicht installiert, sondern habe das die Verschlüsselung fürs eduroam eingerichtet wie hier beschrieben: http://wiki.freitagsrunde.org/WLAN

Ich installier wicd nochmal mit AddOn, vielleicht klappt es ja dann.

Geht es denn auch um die TU-Berlin?

Ja, die Freitagsrunde sind Informatiker und Elektrotechniker der TU Berlin.

Ich habe wicd und das AddOn jetzt installiert. Als Verschlüsselungstyp fürs eduroam habe ich WPA2 Enterprise gewählt, dann werde ich aber nach einer anonymen Identität gefragt und das Feld kann ich auch nicht leer lassen. Wenn ich z.B. ein Leerzeichen eintrage, kommt ein "Connection failed: Bad password"-Fehler.

Im Network-Manager sollte laut Anleitung der TU das Feld für die anonyme Identität leer sein. Das geht bei wicd nicht, weißt du, was ich da eintragen muss?
