So I agree that the modem disconnect seen when WiFi is toggled off is
rare, that said, per my previous comment #38, it looks NM definitely
gets in a state where it doesn't recover.  I didn't see where you
specified how long you waited after the disconnect; it's possible that
this is a permutation of bug #1418077, but as I didn't see a state
message showing the modem transition to "searching", I don't think this
is the case.

This may just be a timing issue.  In this case, the route failures cause
the connection failure, which is different than a connection failing due
to the context being de-activated.   Maybe it's this case which leaves
the modem in 'connected' state?

I will try my force-route failure experiment on krillin/RTM and see if
it triggers the same scenario.

Also, this may be related to the FM failures seen in RTM on arale and
mako; see bug #1445080 for details.

Title:
  Leaving Wifi does not connect to mobile carrier data (GSM)

Status in the base for Ubuntu mobile products:
  Confirmed
Status in ofono package in Ubuntu:
  In Progress
Status in ofono package in Ubuntu RTM:
  In Progress

Bug description:
  After leaving my home or work wifi, my Bq phone cannot connect to the
  data from my mobile carrier. The only thing that works is rebooting
  the phone.

  Steps to reproduce:

  1- Connect your phone to password secure Wifi.
  2- Suspend phone.
  3- Leave wifi area and resume phone
  4- Wait for 3g data to kick in (appears 3g indicator instead of wifi)
  5- No connection established. I have waited for more than 30 mins.

  6- A reboot of the phone fixes this issue.

  Really annoying to have to reboot phone 3-4 times a day.
