Cannot Find Printer while Using Wi-Fi

First, make sure printer is turned on. Next, make sure that you can view any web page on the Internet with your computer. After confirming the two, use the IJ Network Device Setup Utility to diagnose and repair network status.

Select the link below to download IJ Network Device Setup Utility and install it.

See below for starting up IJ Network Device Setup Utility.

If the problem persists after diagnosis and repair with IJ Network Device Setup Utility, check the following items.

  1. Check1 Check the icon on LCD.

    The icon appears by pressing COPY button, SCAN button, or Setup button.

    If the icon is not displayed, from the setup menu select Device settings > LAN settings > Wi-Fi > Wi-Fi enab./disable and then select Enable.

    If the icon is displayed, see the following check to make sure whether printer setup is complete or the settings of wireless router to connect are correct.

  2. Check2 Make sure printer setup is complete on the computer.

    If it is not, click here and perform setup.

  3. Check3 Make sure printer and wireless router network settings match.

    Make sure the network settings of the printer (e.g. network name (SSID) or network key (password), 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.

    Note

    • Use 2.4 GHz frequency band to connect to a wireless router. Match the network name (SSID) set for the printer with that for 2.4 GHz frequency band of the wireless router.

    To check the network name (SSID) set for the printer, print out the network setting information of the printer.

  4. Check4 Make sure the printer is not placed too far away from the wireless router.

    If the distance between the printer and wireless router is too far, wireless communication becomes poor. Place the printer and wireless router close to each other.

  5. Check5 Make sure wireless signal is strong. Monitor signal strength and move printer and wireless router as necessary.

    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.

    Check the signal strength on the LCD.

  6. Check6 Make sure Enable bidirectional support is selected in the Ports sheet of the Printer properties dialog box. (Windows)

    If not, select it to enable bidirectional support.

  7. Check7 Make sure security software's firewall is off.

    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.

  8. Check8 If printer is connected to an AirPort Base Station via LAN, make sure you use alphanumeric characters for network name (SSID). (macOS)

If the problem is not resolved, click here and redo setup.
