with those of the wireless router.
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 machine, print out the network setting information.

Make sure computer network settings are correct.

Make sure the computer can communicate with the wireless router over the wireless LAN.
Make sure machine is not placed too far away from the wireless router.
Check9
Place the wireless router and machine 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 machine cannot communicate with the computer over a wireless
LAN due to a wall, place the machine 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.
Make sure wireless signal is strong. Monitor signal status and move machine

If you are using any programs that switch between network environments, check their settings. Some programs
use a firewall by default.
