There are many brands and models of access point, we put a sample DHCP configuration of a tp-link. Basically the configuration is the same in all.
We assume that windows assigned to the access point adapter ip 192.168.0.1
Gateway are IP assigned by windows at adapter with access point.
Configure your access point also in SSID if preferred. Remember not to put network security, deactivate wep, wpa, etc.
If your access point does not have dhcp server (eg ubiquiti some models), Hotspot incorporates a dhcp open source DHCP Server with detailed installation instructions.
