[Mathieu Trudel-Lapierre <mathieu.tl@xxxxxxxxx>]

I'm seeing this peculiar message in syslog:
Oct  7 13:22:03 ubuntu-phablet kernel: [14655.999891] (0)[1956:rild][ccci/net] (1)CCMNI0 close 

I'm not sure why rild decides it suddently wants to turn ccmni0 off; but
that could well explain why there is no ip address on the interface, and
no routes to support setting the default gateway back to mobile later
on.

I don't think it's requested by NM; because there is earlier evidence in the same log that when NM asks for it; you instead see a message like:
(0)[1956:NetworkManager][ccci/net] (1)CCMNI0 close 

Along with NM's own logs for the disconnection; but I'll keep looking at
that side anyway.

Reassigning to Tony for now, until we can verify if it's rild that is
doing something it shouldn't.

Title:
  turned off wifi to test 3g I see H in the indicator but I recieve
  nothing from the system

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.
