imageCLASS MF642Cdw cannot connect to Wi-Fi

[sketty55]

Hi everyone. I have an issue with a Canon printer model mf642cdw which was connect to wifi for the past year and working fine. I haven't changed any settings, but now it is not connected to wifi and when i try to connect to the network on the printers screen, it says It can’t connect to my internet with the following message: 

Could not connect. Make sure the security settings configured for the device and the access point are the same.

What do I need to do?

Greetings , 

The MF642Cdw supports a 2.4 GHz broadcast that supports WPA2 encryption.  Please ensure your network meets these requirements.

Things that might cause issues:

Using the same SSID name on a dual or tri-band router.

Specifying and incorrect encryption type WPA3 versus WPA2.
