I just tested a simple script (called "network_restar") to make NM
restart upon resume... and IT HAS WORKED!
Rather than creating it via terminal right into the relative folder
(/lib/systemd/system-sleep), I did it thru text editor, saved it in Home
and moved it to that folder as sudo.
>> Script content:
case "${1}" in
resume|thaw)
sudo service network-manager restart
;;
esac
>> After this, run (line by line, supposing you have saved script your
Home dir):
sudo su
(type your root password!)
mv network_restart /lib/systemd/system-sleep
chmod +x /lib/systemd/system-sleep/network_restart
>> Script seen on: http://askubuntu.com/questions/766718/script-to-
restart-network-manager-after-resume-from-sleep

Title:
nm-applet not showing existing wifi connection
Status in network-manager-applet package in Ubuntu:
Incomplete
Bug description:
Frequently, not always, the wifi connection and the existing wifi
networks don't show up on nm-applet. Still, the default network
connection is established in the background. But nm-applet does not
allow connection management.
In the picture: nm-applet shows no connections/netowrks but in the
connection information dialog you can confirm that the wifi connection
was established
