Troubleshooting
Cannot Connect to the Network
Check the following items to make sure that the machine is ready to be connected to a network.
Proceed to the next page if you still cannot connect the machine to the network.
 Check the status of the computer.
• Have the settings for the computer, the wireless LAN router, or access point been
completed?
• Are the cables (power cable or network cables) for the wireless LAN router or access point
disconnected?
• Is the wireless LAN router or access point turned ON?
If you cannot connect to the Internet even after checking:
• Turn OFF each device and turn each one back ON.
• Wait a few moments, and reconnect to the Internet.
Check the installation sites for the machine and the wireless LAN router
(access point).
• Is the distance between the machine and the wireless LAN router (access point) close
enough to communicate?
• Is there any obstacle, such as a wall, between the machine and the wireless LAN router
(access point)?
• Is there any electronic device, such as a microwave or a digital cordless phone, that emit
electronic wave?
