It may take a while for the computer to obtain the IP address, or you may need to restart your computer.

Search for the machine again after confirming a valid IP address is assigned to the computer.

Cannot Communicate with the Machine over the Wireless LAN

1. Check1 Make sure that the machine is turned on.

2. Check2 Are the network settings of the machine identical with those of the wireless router?

   Make sure that the network settings of the machine (e.g. wireless router name, SSID, network key, etc.) are identical 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.

   Printing Out Network Setting Information

   If the network settings of the machine are not identical with those of the wireless router, change the network settings of the machine to match with those of the wireless router using IJ Network Tool.

3. Check3 Make sure that the machine is not placed far away from the wireless router.

   The wireless router is located indoors within the effective range for wireless communication. Locate the machine within 164 ft. / 50 m from the wireless router.

4. Check4 Make sure that there is no obstruction.

   Wireless communication between different rooms or floors is generally poor. Adjust the location of the devices.

5. Check5 Make sure that there is no source of radio wave interference in your vicinity.

   If a device (e.g. microwave oven) using the same frequency bandwidth as the wireless station is placed nearby, the device may cause interference. Place the wireless station as far away from the interference source as possible.

6. Check6 Make sure that the network settings of the computer are correct.

   For the procedures to connect a network device to the computer and set them up, refer to the instruction manual of your network device or contact its manufacturer.

7. Check7 Make sure that the radio status is good and adjust the installation positions while monitoring the radio status with IJ Network Tool.

   Monitoring Wireless Network Status

8. Check8 Make sure that a valid wireless channel is used.

   The wireless channel to be used may be limited depending on wireless network devices installed in the computer. Refer to the instruction manual provided with your computer or your wireless network device to specify the valid wireless channel.

9. Check9 Make sure that the channel confirmed in Check 8 can communicate with the computer.

   If not, change the channel set to the wireless router.

10. Check10 Make sure that the firewall of the security software is disabled.

    If the firewall function of your security software is turned on, a message may appear warning that Canon software is attempting to access the network. If the warning message appears, set the security software to always allow access.

    If using any programs that switch the network environment, check their settings. Some programs will enable a firewall by default.

11. Check11 When using a router, connect the machine and computer to the LAN side (same network segment).

If the problem is not resolved, perform setup again with the Setup CD-ROM or perform it according to the instructions on our website.

• For placement:

  Make sure that there is no barrier or obstacle between the wireless router and the machine.
