[Bug 1450790] Re: Phone not connecting to mobile data until rebooting

 

@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.

Bug description:
  Whenever I walk out of WiFi range, my phone does not connect to mobile
  data. Toggling flight mode does not help. I have to reboot the phone.
  When then I finally manage to connect after rebooting, if the signal
  strength drops and the phone would want to switch from 3G to 2G, it
  disconnects and I have to reboot again to get mobile data.
