@Pat, thanks for the logs. I can see there are time periods where you lose registration for a while. Also, I see that initially two networks are found:
310/410 -> AT&T, GSM and UMTS bands compatible with MX4 310/120 -> Sprint, LTE bands non compatible with MX4 but after a while I see notifications showing only the Sprint network. Besides, Sprint should not appear here unless you can register there. Do you know if there is some agreement between Sprint and AT&T to share network in your area, maybe depending on the band? Also, could you try going to SystemSettings->Cellular->Carrier&APN->Carrier and check which operators do you see there? Try to select AT&T as your only operator and see if that improves the situation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1607823 Title: Cellular connection drops out To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1607823/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
