To check the settings of the wireless router, refer to the instruction manual provided with it or contact its manufacturer. To check the current network settings of the printer, print out the network setting information.

Network Settings (IJ Network Device Setup Utility) (Windows) Network Communication (Mac OS) Check3 Make sure the printer is not placed too far away from the wireless router. 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. 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. 1091
