WPS (Wi-Fi Protected Setup) — fastest method
WPS works when your router has a WPS button, usually on the back or side. On the printer, go to the network or wireless menu and select WPS or Wi-Fi Protected Setup. Press the WPS button on the router within 2 minutes. The printer and router will pair automatically without you entering a password. This method is supported by most HP, Canon, Epson, and Brother models released after 2010.
