Checking wireless router location
After checking the wireless router setting, make sure the printer is not placed far away from the wireless router.
The printer can be up to 50 m (164 ft) from the wireless router indoors. Make sure the printer is close enough to the wireless router to be used.
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.

Tap the icon on the lower left and select See settings.
For more on the wireless router, refer to the instruction manual supplied with the wireless router or contact its manufacturer.
After taking measures above, click Redetect on the Check Printer Settings screen to redetect the printer.

If the printer cannot be detected, the printer is not connected to the wireless router. Connect the printer to the wireless router.
