The WPS button on a router stands for Wi-Fi Protected Setup. It is a feature that makes it easier to connect devices to a secure wireless network without having to enter a password. The WPS button is usually located on the back or front panel of the router. When you press the WPS button on the router, it turns on the discovery of new devices and allows them to connect to the wireless network without having to enter the network password. The WPS feature is not the same as Wi-Fi, which is your wireless network. It is important to note that the WPS feature should be disabled when not in use to prevent unauthorized access to your network.
