If your wireless LAN router is compatible with the WPS function, push the WPS buttons on both PCS and the wireless LAN router to establish a wireless LAN connection.
For details on the location of the WPS button on your wireless LAN router, refer to the instruction manual of your wireless LAN router.
If the smartphone/tablet is already connected to the same wireless LAN router as PCS, connection between PCS and the smartphone/tablet via wireless LAN router will be established with only this operation.
If the smartphone/tablet is not connected to the wireless LAN router, connect it following the instructions in Establishing a wireless LAN connection between a smartphone/tablet and a wireless LAN router.
