Public bug reported:
Sometimes, after waking up the laptop from hibernation, nm-applet won't
scan for networks. In these cases, the list of available Wifis can be
just outdated or directly empty.
Switching Wireless on/off and Network on/off doesn't trigger a scan.
Usually running sudo iwlist <interface> scan on a terminal makes the
wifi networks available immediately in nm-applet
I'm using 16.04 (ubt had the same problem on 15.10)
network-manager-gnome:
Installed: 1.2.0-0ubuntu0.16.04.4
