1. sudo apt-get update

2. sudo apt-get upgrade

3. sudo apt-get install dnsmasq hostapd screen

4. Edit /etc/rc.local and add the following ABOVE exit 0

service hostapd stop
service dnsmasq start
iw dev wlan0 interface add uap0 type __ap
iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
ifdown wlan0
ip link set uap0 up
ip addr add 192.168.99.1/24 broadcast 192.168.99.255 dev uap0
service hostapd start
ifup wlan0
service dnsmasq start

5. Edit the /etc/dnsmasq file and add and/or adjust the following for your AP's DHCP network scope:

interface=uap0
dhcp-range=192.168.4.20,192.168.4.100,255.255.255.0,12h

6. Edit your /etc/hostapd/hostapd.conf file and change your SSID and passphrase appropriately.

interface=uap0
driver=nl80211
ssid=YOUR-SSID
hw_mode=g
channel=7
wmm_enabled=0
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=YOUR-PASSPHRASE
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

7. Edit /etc/default/hostapd and add this line:
   DAEMON_CONF="/etc/hostapd/hostapd.conf"

8. If you intend to use an attached ethernet usb dongle or the Pi Zero as a wireless client WHILE it is an AP, you will need to allow for routing by editing /etc/sysctl.conf and uncommenting: net.ipv4.ip_forward=1

9. Reboot

10. Connect the Zero to the network device via USB.

11. Login to the Zero remotely and run screen /dev/ttyUSB0

12. CTRL-A then type K will break out and kill the "screen"
