Hmm, I see now that you have full coverage (5/5). I see that the modem suddenly loses the data connection port:
modem-manager[14730]: <debug> [1353275176.363323] [mm-serial-port.c:697] data_available(): (ttyUSB0) unexpected port hangup! But then right after it is connected: modem-manager[14730]: <info> [1353275176.364505] [mm-modem.c:764] mm_modem_set_state(): Modem /org/freedesktop/ModemManager/Modems/0: state changed (disconnecting -> connected) Aleksander: is there more Huawei port numbering lies? Or maybe the modem is not properly implemented/unstable for using LTE without QMI? ** Changed in: modemmanager (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1042456 Title: Huawei e398 doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1042456/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
