Same bug on Alienware 17 R4 running ubuntu 16.04 LTS kernel 4.4.0-31-generic
#50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux.
sudo service network-manager restart
does fix it.
Still no official fix though ?

Title:
Network manager applet unable to control wifi after suspend in 16.04
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
After resume from suspend network manager no longer allows me to
control my wifi card, view available wireless networks, or select new
ones. Oddly enough, I'm still able to communicate on the network that
I was connected to prior to suspend.
Running
# sudo service network-manager restart
resolves the issue until the next suspend/resume.
I'll copy what I think is the relevant portion of syslog below
