Comment 5 for bug 1371032

Instead of asking for specific logs and since this is a long running thing and ubuntu-bug isn't working well for the rtm images; I'm going to ask you to install network-test-session from https://launchpad.net/~phablet-team/+archive/ubuntu/testtools by either
- a wget dpkg -i on it should work.
- adding the sources list of the PPA to the rtm image is possible
   # echo "deb http://ppa.launchpad.net/phablet-team/testtools/ubuntu utopic main" > /etc/apt/sources.list.d/testools.list
   # apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 5E51A24C
   # apt update
   # echo this next command brings in the location test deb, but we need the # echo latest package
   # apt install network-test-session
- reboot

And read
https://github.com/sergiusens/network-test-session/blob/master/README.md

Once your test session is done, please upload the tar it creates.

A quick note, once start returns, you can disconnect the phone and wander around, just don't reboot.
