[Bug 1378416] Re: turned off wifi to test 3g I see H in the indicator but I recieve nothing from the system

 

This looks like the culprit, according to Mathieu, -12 indicates object-
not-found from libnl ( netlink ):

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.
