Are network settings of your smartphone/tablet identical with those of wireless
router?
Make sure the network settings of your smartphone/tablet (e.g. wireless router name, SSID, network key, etc.)
are identical with those of the wireless router.
To check the settings of your smartphone/tablet, refer to the instruction manual provided with it.
If the network settings of your smartphone/tablet are not identical with those of the wireless router, change the
network settings of it to match with those of the wireless router.
Check6
Make sure the printer is not placed too far away from the wireless router.
If the distance between the printer and wireless router is too far, wireless communication becomes poor. Place
the printer and wireless router close to each other.
Note
• Though an antenna is attached to most wireless routers, note that some of them have it inside.
Check7
Make sure wireless signal is strong. Monitor signal status and move printer
and wireless router as necessary.
Place the wireless router and printer where there are no obstacles between them. Wireless communication
between different rooms or floors is generally poor. Wireless communication can be impeded by building
materials containing metal or concrete. If the printer cannot communicate with the computer over a wireless
LAN due to a wall, place the printer and the computer in the same room.
