@Michael Thanks for the updates to the bug. I mentioned the custom APN as when I examined your syslog, it appeared that Network Manager was only trying to activate context3, which was the __ubuntu_custom_internet_apn.
Regarding the APN editor, it's been in rough shape, and one bug ( now fixed ) was that if you just happened to visit the settings page, but didn't do anything, a custom APN would be created automatically. We actually spent time working on APN editor improvements at a sprint last week. Finally after looking at your logs, a couple of observations: 1. You're roaming, and have enabled data roaming 2. At times ( 14:11, 15:30, 22:29, 22:35 - 23:14 ) it looks like you have poor cell reception as your phone is dropping of GPRS quite a bit, and usually when the phone re-attaches, NM fails to activate context1 every time, and the error is 'no-secrets'. Note, GPRS detaching and re- attaching usually means you're losing a connection from your operator, but as we don't log operator registration itself, I can't tell if it's just GPRS that's dropping. 3. The only time NM succeeds activating context1 is after reboots, which I can see from your syslog. 4. Are you aware that your phone tried to attach to a LasarJet printer?? ;)- Finally, I think this may be related to bug #1435776 as it deals with an APN with 'Username', but no 'Password', but that's just because both involve secrets. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1450790 Title: Phone not connecting to mobile data until rebooting To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1450790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
