WPS stands for Wi-Fi Protected Setup. It is a method to connect devices to a Wi-Fi network. It works only for the WPA or WPA2 protected networks. The two WPS methods are the WPS Push button and the WPS PIN methods. The WPS PIN method does not ask you to enter the Wi-Fi network name and password to connect to the network. The encrypted WPS PIN of the router is available on the router’s web-based setup page. The WPS PIN is an 8 digit number. You can connect a device using its WPS PIN.
