Make sure the printer is not placed too far away from the device.
Place the device 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.
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.
Place devices a suitable distance from the printer.
