filtering, and DHCP function.
For more on checking the settings of the wireless router, refer to the instruction manual supplied with the wireless router or contact the
manufacturer.

• Depending on the wireless router, note that different network name (SSID) is assigned for a bandwidth (2.4 GHz or 5 GHz) or its usage (for
PC or game machine), using alphanumeric characters at the end of network name (SSID).
Once you complete checking the wireless router, configure the network settings for your computer. For the procedures, refer to the instruction
manual supplied with the computer, or contact the manufacturer.

• Checking the location of wireless router:
After checking the wireless router setting, make sure the printer is not placed too far away from the wireless router. The printer can be up 50
m (164 ft.) from the wireless router indoors if unobstructed. The printer is designed for indoor use. Make sure the printer is close enough to the
wireless router to be used.
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.
• Checking the location of printer:
Make sure that the printer is not placed behind an object. The printer may not be connected when placed behind a wall or on a shelf. Try to
place the printer in a location where there is no obstacle.
For details, see the instruction manual supplied with the wireless router or contact the manufacturer.
