Privacy Separator/SSID Separator/Network Separation Function
- Turning off the band steering feature (determines the appropriate frequency band to connect to when the number of devices connected increases and the 2.4 GHz and 5 GHz frequency bands are congested) in your wireless router's settings may help.
- If the same SSID is set for both 2.4 GHz and 5 GHz, changing them to different SSIDs may enable you to connect.If your printer does not support 5 GHz connection, connect the PC to a Wi-Fi router with 2.4 GHz enabled and set it up again.
- If your printer does not support 5 GHz connection, the wireless router must have 2.4 GHz enabled.If your printer does not support 5 GHz connection, connect the PC to a Wi-Fi router with 2.4 GHz enabled and set it up again.
In the following cases, set up the printer again.
-
When you buy a new computer or wireless router
-
When you change the settings on your wireless router
-
When the connection method (Wi-Fi / USB) of the printer is changed
-
When you forget the administrator password of the printer
When you forget the administrator password of the printer, select Settings on HOME screen and Device settings > Reset settings > Reset all > Yes and redo setup to restore to default administrator password.

In Other Cases Than Above:
If the printer suddenly stops working, even though you have not changed the settings of the device or network to which it is connected, or if you cannot find the printer during the setup process, check and solve the problem, using Wi-Fi Connection Assistant. After the condition improves, redo the setup of the printer.
Wi-Fi Connection Assistant is a powerful solution tool for network problems.
Step1 : Check Basic Items for Network.
-
Check1 Check power status.
Check your printer and the network device (wireless router, etc.) are turned on.
If you are in the process of setting up, interrupt it and check if the wireless router (modem) is turned on and then check if the printer is turned on.
-
Check if network device such as router is turned on.
If network devices are not turned on, turn on the power. If the network devices are on, turn them off and on again.
It may take a while for the network device to become ready for use once they are turned on.
Proceed once the network device such as router is ready for use.
-
Check if printer is turned on
If printer is not turned on, turn on the power. If the printer is on, turn it off and on again.
Proceed once you complete checking the power status above.
-
-
Check2 Check PC network connection.
If your computer and network devices (wireless router, etc.) are fully configured, your computer is ready to connect to the network.
-
Check the settings of the network device (wireless router, etc.).
Connect to the Internet and see if you can browse any web page. If you cannot view web pages on your computer, check wireless router network connection settings, such as IP address filtering, MAC address filtering, and DHCP function.
To check the network name (SSID) of the wireless router the printer is connected to, print the network settings.
Note
-
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).
-
For more on checking the settings of the wireless router, refer to the instruction manual supplied with the wireless router or contact the manufacturer.
If you use an encryption key, specify it for the network name (SSID) you are using. For details, see Setting an Encryption Key.
-
-
Check PC network connection.
For the procedures, refer to the instruction manual supplied with the computer, or contact the manufacturer.
Once you complete setting up the wireless router and your computer, configure the settings on your computer in order to view web pages, using the information of the wireless router.
Proceed once you complete checking the network connection above.

Check3 Check printer's network settings.
Make sure the (Wi-Fi) icon is displayed on the upper left corner of HOME screen.
If (Wi-Fi not connect) icon is displayed.
(Wi-Fi not connect) icon indicates that the wireless router and the printer are not connected. Check the setting of printer. Reconsider the location of the wireless router and the printer in the next check.
If Easy wireless connect button(Easy wireless connect) is on.
"Easy wireless connect" is waiting for setup. Connect a device to the printer with the application on computer, smartphone or tablet.
If only (Wi-Fi off) or (Wireless direct) icon is displayed.
The printer is not set to use Wi-Fi.
Select Settings on HOME screen > Device settings > LAN settings > Wi-Fi in this order, and select Enable for Advanced mode.

Check4 Check location of wireless router.
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. 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.
Step2 : Solve Problems, Using Wi-Fi Connection Assistant.
Diagnose and repair the network connections using Wi-Fi Connection Assistant.
Download Wi-Fi Connection Assistant from the below page, and install it on your computer.
Refer to below in regard to starting up Wi-Fi Connection Assistant.

For macOS:
Step3 : If the Solution Tool Does Not Solve the Problem.
-
Check1 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.
-
Check2 If printer is connected to AirPort Base Station via LAN, make sure you use alphanumeric characters for network name (SSID). (macOS)
If characters other than single-byte alphanumeric characters are used in the network name (SSID), you will not be able to connect correctly. Change the network name (SSID) to single-byte alphanumeric characters only.
