Comment 44 for bug 1574347

One more try:
- new clean released xenial 16.04 amd64 install on a spare partition
- set update server to Main
- update & upgrade
- reboot
- enable -proposed
- update & upgrade
- all relevant package versions precisely as in #32 (@Aron Xu: please note that not all libnm-* are 1.2.0-0ubuntu0.16.04.2, namely libnm-gtk-common and libnm-gtk0:amd64 which are 16.04.1)
-reboot

Result: still not working properly after wifi/AP/suspend off/on.
The only improvement is that now I can make it work after a boot/login with a 'sudo systemctl restart NetworkManager.service' as I wrote in #33.
I can upload a movie for non-believers :)
