I'm experiencing this with the regular Gnome 15.04. It happened while I've been continuously switching "Enable Wi-fi" on/off while messing with my router because my SSID wasn't showing. It was from a desktop after a reboot. Restarting the "NetworkManager.service" (which was still active and running) brought back the wifi functionality.
