An access point AP interface needs to know its network and broadcast details. A client is required to receive dns and dhcp requests.

• Enable builtin wireless interface at boot auto wlan0
• Set static ipv4 settings iface wlan0 inet static to receive dns and dhcp requests
  • address 192.168.7.1
  • netmask 255.255.255.0

	      # Configure wifi as access point
	      auto wlan0
	      iface wlan0 inet static
	          hostapd /etc/hostapd/hostapd.conf
	          address 192.168.7.1
	          netmask 255.255.255.0
