GNOME Bugzilla – Bug 574636
Can't connect to 3G/CDMA network since 0.7.1-RC3
Last modified: 2009-03-28 17:09:44 UTC
Please describe the problem: I'm testing Ubuntu Janty with NM 0.7.99 (0.7.1-RC3). The connection for my usb 3G/HSDPA modem sometimes doesn't work. I select the connection through nm-applet and it seems to start connecting but after few seconds I get the message that the network is disconnected. I use the same configuration as in Intrepid w/ NM-0.7 where the connection works flawlessy every time I use it. I've tried to restart NM with /etc/init.d/NetworkManager restart and to unplug/replug the modem's usb cable, or to reboot the system and sometimes the connection works fine. Steps to reproduce: 1. Click on nm-applet and select a GSM/3G network to start connection. 2. Wait few seconds while the connection seems to start 3. nm-applet says that the connection is closed. Actual results: The modem don't start the connection. Expected results: The modem connects to the net. Does this happen every time? Not every time. Other information: I have an Option Icon 1.8mb/s modem : Bus 002 Device 002: ID 0af0:6600 Option GlobeTrotter 3G+ datacard I use a tool switch the modem from usb-storage to modem called 'icon_switch' and I have udev rules the manage this tool.

Created attachment 130329 [details] Nm log of a successfully connection. This happened after restarting NM daemon and unplugging/replugging the modem's usb cable.
Seems like a transient issue; in both cases the modem initialization times out but in the "success" case the modem responds after a suspend/resume. Can you attach the output of "lshal" for your system?

I'm sorry for double posting the attachment but bugzilla was working bad in the last few days. I did some tests and I can't connect with NM when rebooting or unplugging/replugging the device with the system turned on. The only way I have to get it working is to shutdown the system and than boot up (no reboot or NM/Hal daemons restart).
Could it be related to this? Sometimes after unplugging and re-plugging the modem I have double entry in nm-applet. http://bugs.freedesktop.org/show_bug.cgi?id=20703
Installed this morning the updated package (0.7.1~rc3.2.gitb8fc83a7-0ubuntu1), seems to fix the bug. Well done guys! I mark the bug as fixed.
