[Bug 1445080] Re: Cellular data not activated after exiting flight mode
I did managed to reproduce this on arale ( vivid-proposed #165 ) with
the recent version of NM which fixes bug #1418077.
'nmcli d' shows the modem as disconnected. list-modems shows the
ConnectionManager interface both powered and attached per Alfonso's
original description. The modem is registered to a carrier using UMTS,
and list-contexts shows no active contexts.
** Changed in: network-manager (Ubuntu)
Status: Incomplete => Confirmed

Title:
Cellular data not activated after exiting flight mode
Status in the base for Ubuntu mobile products:
New
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
Cellular data is not activated in ~50% of the cases in arale after
setting then unsetting flight mode.
I obtained the attached log this way:
1. Disabled wifi (to have less noise) and removed syslog (to make smaller the attached one)
2. Reboot
3. See cellular data is on: route is right, I have network access
4. Set flight mode
5. Unset flight mode
6. Data is not restored even after waiting for a few minutes. ccmni0 interface is down.
list-modems shows that the modem is data-attached
list-contexts output shows that no IP context has been activated
Doing
usr/share/ofono/scripts/activate-context 1
sudo ip route add default dev ccmni0
ping 8.8.8.8
works and I receive the ping responses.
