Public bug reported:
First, I reported bug 1164023 as there was also a crash of modemmanager,
but after this crash being fixed I still do not get a connection to
mobile broadband.
This bug is a regression against 12.10. Booting from a 12.10 live CD I
can use the mobile broadband.
The modem is built-in (Ericsson Business Mobile Networks BV).
I do not get any crashes any more, but no connection. According to
syslog, modem-manager is trying something infinitely.
I do not know whether really modemmanager or network-manager is the
culprit.
I have switched to debug logging via
sudo python debug-helper.py --mm debug
sudo python debug-helper.py --nm debug
Then I have captured the syslog via
tail -n0 -f /var/log/syslog > /tmp/syslog
While capturing, I have first clicked "Enable Mobile Broadband" in the
Network Manager menu, near the bottom. After some seconds I got an OSD
pop-up that I am registered for GSN or so. Now I clicked on "T-Mobile
(Telekom) Default" in the "Mobile Broadband" section. The indicator
applet icon of the Network Manager started spinning, telling that it is
searched for a network. After some time it stopped spinning without
connection established. After that, modem-manager is still active in the
syslog. I waited some minutes before stopping to capture.
syslog is attached.
