Public bug reported:
Steps: Suspend, wait, resume, a few times.
The Network Manager applet shows WiFi is enabled and shows just one or a
handful of WiFi names, they don't include some that are known to be
available and in use on other computers.
Disabling and enabling WiFi does not fix the problem.
Disabling and enabling networking does not fix the problem.
Adding the following does not help:
/etc/pm/config.d/unload_modules
SUSPEND_MODULES="$SUSPEND_MODULES iwlwifi"
Only workaround which works perfectly and instantly is to run:
sudo service network-manager restart
