Followed the instructions on the RaspberryPi.org web site to configure my Raspberry Pi Zero W as a wireless access point. page 
**NOTE:** You need to configure the Pi using the console rather than SSH because the instructions will cause the Pi to disconnect from your local network. You may also need to follow the instructions completely in order for the static IP address to be assigned to wlan0.
To use as a wireless access point wlan0 must be assigned a static IP address so that it does not connect to any other wireless networks. Edit the DHCP configure file by entering:
sudo nano /etc/dhcpcd.conf
Add the following at the end of the file if it is not already there.
interface wlan0 static ip_address=192.168.4.1/24 nohook wpa_supplicant
At this point you can either restart the Raspberry Pi or enter the following. Note if you are connected to the Raspberry Pi via SSH you will likely lose access. The settings do not take affect until the Pi is restarted.
sudo systemctl restart dhcpcd
