The debug log above seemed to have used the generic GSM driver. Attached here is the log using Ericsson MBM plugin. The last part where the connection problem occur is the same:

I also see that it seems to repeat "AT+CREG?". Maybe echo got enabled after disconnection and modemmanager can't handle it? ** Attachment added: "Debug output of modemmanager using Ericsson MBM plugin" https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/769497/+attachment/2105356/+files/modemmanager_ericsson_bug.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/769497 Title: Reconnect not possible after disconnection or lost connection using Ericsson MBM -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
