[Tony Espy <1378416@xxxxxxxxxxxxxxxxxx>]

The current theory is that some event is causing rild to
disconnect/destroy the GPRS device, and that this event doesn't generate
the proper unsolicited event to ofono.

Unfortunately, we haven't yet been able to reliably reproduce this with
the latest images.

After discussing with Dave, he's described that this usually happens to
him when he leaves his flat via an elevator which when between floors,
causes signal to be lost.   That said, we have tested forcing modem
disconnects in the past on krillin, and they worked as expected.  It's
possible that the disconnect is operator induced...

That said, I've added an incomplete network-manager task to the bug as
we once we better understand this bug, it will probably be wise to add
logic to network-manager to mark the connection as invalid when the GPRS
device disappears.  This will make our stack more robust.

Title:
  [krillin] disable WiFi, Mobile Data not available

Status in “network-manager” package in Ubuntu:
  Incomplete
Status in “ofono” package in Ubuntu:
  In Progress

Bug description:
  STEPS:
  1. Install RTM88 on krillin
  2. Use the system a litlle on wifi
  3. Pull down the indicator network
  4. Disable Wifi

  EXPECTED:
  I expect the system to seemless flip over to using 3g

  ACTUAL:
  I got no page (see screen shot) I tried pinging google and got ping: unknown host google.com

  ip route gave no feedback
  phablet@ubuntu-phablet:~$ nmcli dev
  DEVICE     TYPE              STATE
  /ril_1     gsm               disconnected
  /ril_0     gsm               connected
  wlan0      802-11-wireless   unavailable

  Devices is correct.

  The debug.txt in comment #3 clearly shows that mobile data is
  connected via the list-modems output and list-contexts output.  This
  output also agrees with the nmcli output which shows /ril_0 as
  connected.  The smoking gun here looks to be the routing table, which
  is empty.
