			=== Take down WiFi when not needed ===



			=== Restore WiFi ===

			There are few circumstances in which I want the phone to decide for itself to reenable WiFi, however it would be helpful to do so when I arrive home and put it on charge.

			So we need to

			* trigger when the phone is placed on charge
			* enable WiFi interface
			* attempt autoconnect to home wireless network
			* consider whether to disable WiFi if not successful in reaching home network
