On other interesting point is that settings for the mobile data context
are a bit odd in that the gateway and address returned from the operator
are both the same:

Interface=ccmni0 DomainNameServers=149.254.230.7,149.254.192.126,
Gateway=10.129.20.112 Address=10.129.20.112 Netmask=255.255.255.0
Method=static

This doesn't appear to cause problems when the mobile data connection is
initially configured, however for some reason when WiFi is disabled it
is causing an issue.

On initial configuration, we setup up the route for mobile data and then
set it as default.

When WiFi connection, we setup a route for WiFi, then make it the
default route ( ie. we don't remove the mobile data route ).

When WiFi is again disabled, we remove the WiFi route, and attempt to
set the mobile data route as the default again.  It's during this logic
that the failure occurs.

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

Status in “network-manager” package in Ubuntu:
  Confirmed

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.
