Gelöst _ Ubuntu 14.04 , WWAN im X61 kaputt

wileE · 14 Mai 2015

Ich habe hier ein Problem mit dem WWAN in meinem X61.
Installiert ist Ubuntu Gnome 14.04, Kernel 3.13.0-52-generic. Das Problem besteht ebenso bei Ubuntu 14.04 mit Unity oder Mate. Auch mit 15.04 Ubuntu Gnome.

Mit Ubuntu 12.04 oder Win7 geht dagegen alles. Hardware und SIM sind also OK.

Problem: Die Verbindung zum Vodafone Netz kommt nicht zustande. Nach etwa einer Minute bricht der Verbindungsversuch ab.
Und es muss ein Problem mit diesem X61 sein, denn es geht nicht mit der intenen Sierra ~~und auch nicht mit einem Expresscard Modem.~~

Die Hardware in diesem X61 etwas anders als Standard: das Modem steckt in einem dritten Mini PCIe Slot mit eigenem Stromschalter und es hat einen Expresscard Slot. Aber Ubuntu 12.04 kommt da mit klar.

Jemand eine Idee was da schiefgeht?

Das interne Modem wird nicht über rfkill geschaltet.

Prost!

Ist die Firmware geladen?

Wie ich schon sagte: die Sierra steckt in einem dritten Slot und hat einen eigenen Schalter. Das sieht TLP nicht.

Firmware? Bei ner alten Sierra? Ich dachte da muss ich mich nur bei Gobi 2000 & Co. drum kümmern.

linrunner · 14 Mai 2015

TLP sieht alles

:

Bus 002 Device 002 ID 1199:683c control = on, autosuspend_delay_ms = 2000 -- Sierra Wireless, Inc. MC8790 Device (sierra)

Am Autosuspend liegts jedenfalls nicht. Übrigens ist explizites Blacklisting der ID nicht mehr nötig, USB_BLACKLIST_WWAN=1 findet die Karte über den Treiber (sierra). Firmware ist in der Karte und wird nicht vom OS aus geladen.

Einbuchen ins Netz tut er sich:

<info> Modem /org/freedesktop/ModemManager1/Modem/0: 3GPP Registration state changed (registering -> home)
<info> Modem /org/freedesktop/ModemManager1/Modem/0: 3GPP location updated (MCC: '0', MNC: '0', Location area code: '18B3', Cell ID: '9C9305F')

<info> Modem /org/freedesktop/ModemManager1/Modem/0: state changed (enabling -> registered)

Die Meldung beim Herstellen der Datenverbindung ist leider wahnsinnig aussagekräftig:

failed to connect modem: No cause information available

Vielleicht die Rechnung nicht bezahlt/kein Guthaben?

Stimmt der APN? Für Vodafone Prepaid (oben steht "Websessions") event.vodafone.de sonst web.vodafone.de

Darüber hinaus fehlt mir im Moment die Phantasie was es sein könnte.

sigur · 14 Mai 2015

Nee es gab da mal ein Firmwareupdate was 1. die Geschwindigkeit von Up und Download verbesserte und 2. was wichtiger war die Stabilitaet im System verbesserte. Mit der Stockfirmware hatte ich teilweise enorme Probleme in der Verbindungsstabilitaet die danach verschwunden war(bzw. das WWAN Modem unter Linux ueberhaupt erkannt wurde). Aber frag mich jetzt bitte nicht wie das Update hies und wo ich das her hatte. Kam soweit ich weiss mit dem Update von einem AT&T EInwahl Programm zusammen.

Prepaid. APN stimmt. So viele verschiedene Ubuntu Versionen wie ich probiert habe, da kann selbst ich nicht konsequent immer falsch eintippen. SIM geht ja auch in anderen Geräten mit Ubuntu Gnome 14.04.
Es ist nur dieses X61 wo es mit nur den Ubuntus ab 14.04 nicht klappt.

danica_talos · 16 Mai 2015

Kommt dir vielleicht eine andere Hardware in die Quere? Ggf. mal andere Sachen (WLAN, BT etc) deaktivieren.

ggrohmann · 16 Mai 2015

Gabs diese Karten auch mit SIMlock?

wileE · 16 Mai 2015

Es liegt weder an anderer Funkhardware, noch an einem SIMlock. Es funktionierte doch unter Ubuntu 12.04 und W7. Außerdem habe ich auch andere Sierras probiert.

Ich habe noch ein paar Distros ausprobiert. Die jüngste Distro mit der WWAN funktioniert ist Ubuntu Gnome 13.10. Alles was älter ist geht sowieso.

Bei allen aktuellen probierten Distros (-buntus, Fedora 21, -puppys) geht es nicht. Da kommt keine richtige Verbindung zustande. Auch die unelegante Methode mit ixconn geht nicht.

In irgendeiner beteiligten Komponente wurde etwas geändert oder weggelassen. Nur was?

Hast du denn, wie von mir vorgeschlagen, alle anderen Sachen deaktiviert um zu schauen, ob eventuell andere Treiber oder ähnliches dein WWAN stören?

Klar hab ich das. Ich hab auch einmal die Funkhardware getauscht. Das Verbindungsproblem gab sich unbeeindruckt.

EDIT

Ich habe auch mal im ubuntuusers Forum einen Thread erstellt.

Lösung: Downgrade des Modem Managers auf Version 0.5.2.0 aus Ubuntu 12.04

Gelöst _ Ubuntu 14.04 , WWAN im X61 kaputt
