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.

Make sure wireless signal is strong. Monitor signal strength and move printer
and wireless router as necessary.
Place the printer and wireless router 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 Wi-Fi due to
a wall, place the printer and the computer in the same room.
In addition, if a device like a microwave oven that emits radio waves of the same frequency bandwidth as a
wireless router is nearby, it may cause interference. Place the wireless router as far away from interference
sources as possible.
