Pi3 / Jessie Lite WiFi issue

	root@raspberrypi:/home/pi# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
	Successfully initialized wpa_supplicant
	ctrl_iface exists and seems to be in use - cannot override it
	Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore
	Failed to initialize control interface 'DIR=/var/run/wpa_supplicant GROUP=netdev'.
	You may have another wpa_supplicant process already running or the file was
	left by an unclean termination of wpa_supplicant in which case you will need
	to manually remove this file before starting wpa_supplicant again.
