Something else that is *very* relevant; if you're running into the issue and filing a new bug, please follow the steps listed above for getting debug logs (see http://wiki.ubuntu.com/DebuggingNetworkManager); and look for the firmware version for your device. The lines should be similar to this:
modem-manager[5955]: <debug> [1337321031.098461] [mm-at-serial-port.c:333] debug_log(): (ttyUSB0): --> 'AT+CGMR<CR>' modem-manager[5955]: <debug> [1337321031.108098] [mm-at-serial-port.c:333] debug_log(): (ttyUSB0): <-- '<CR><LF>11.117.09.04.00<CR><LF><CR><LF>OK<CR><LF>' 11.117.09.04.00 might not be a recent enough firmware to work properly. Seems like the version on my own device: 11.310.16.03.149 might not be good enough or at least seems to crash and reconnect to USB frequently. There are newer revisions available on the Internet, I'll try to upgrade and see how well that works. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/868034 Title: Huawei E220 and E1550 can't connect on Ubuntu 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/modemmanager/+bug/868034/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
