The printer will start searching for the access points, which support WPS. If the push button method appears on the screen and you are not sure if your router or access point supports that technology or not, then you must go to the standard setup screen.
According to the push button method, there are three setup procedures.
Standard Setup: For connecting the access point by entering the password for the network.
WPS: Connect to an access point that is compatible with WPS.
Other Setup : Connect with the network for entering the settings of the access point on your printer directly.
