Note
• For Windows, you can use IJ Network Device Setup Utility to change printer's settings according to those
of wireless router.
Make sure the printer is not placed too far away from the wireless router.
Check6
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.
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.
To check the signal strength:

Check10
If your security software's firewall is on, a message may appear warning you that Canon software is attempting
to access the network. If this warning message appears, set security software to always allow access.
If you are using any programs that switch between network environments, check their settings. Some programs
use a firewall by default.
