Public bug reported:

Sorry for my English, still is not good.

This bug is similar to https://bugs.launchpad.net/ubuntu/+source
/network-manager/+bug/1436427 Connection is established but system
doesn't set a route. Executing ip route is empty.

phablet@ubuntu-phablet:~$ sudo system-image-cli -i
current build number: 26
device name: krillin
channel: ubuntu-touch/stable/bq-aquaris.en

This bug is very very difficult to reproduce. You can follow this steps
and sometimes fail:

1- Keep always screen off.
2- Go to a zone without wifi nor mobile coverage, for example, an underground parking.
3- Stay in for a few minutes.
4- When you go out and screen on mobile you observe connection is established, but sometimes system doesn't set a route, so you don't have Internet access regardless you have a connection established.

In the screenshot attached you can view that.

Workaround: enable plane mode then disable.

This bug happens with wifi connected or disconnected, and with wifi
enabled or disabled. And happens only when phone is suspended. It seems
it's too many suspended and NetworkManager can't perform certain
actions.

I will attach 4 syslog's from early days ago, here you can see when it's
working well and when not.

I've observed that when it works this line is present:
NetworkManager[1500]: <info> Policy set ......[(ccmni0) or (wlan0)] as
default for IPv4 routing and DNS.

If this line is not present it doesn't works.
