imageCLASS MF232w new router communication issue, Wi-Fi light flashing

[Maestro1]

Spectrum/Charter recently sent me a new, super-duper router. I have connected it up, and everything seems working fine...EXCEPT that I now cannot use my Canon MF232w printer. The blue WiFi light on the printer keeps flashing. The router came with a new password, so I'm wondering if I need to enter this new password somewhere in the printer's settings. But where?!

Some printers operate on 2.4GHz WiFi and some newer routers only operate on 5GHz WiFi.

Thank you! Is there a way to check whether mine is 2.4GHz or 5GHz?

Greetings,

Your new ISP issued router may have a sticker on the bottom or side with login and connection information.  

If the sticker displays 2.4 and 5ghz SSID's with respective passwords. It's a dual band router.

You can also log into the router's admin portal and review its wireless settings to see what bands it supports. 

If it uses the same SSID name for all wireless broadcasts, it could keep the printer from making a successful connection.  It might be helpful to give each broadcast a unique name or temporarily disable the broadcast the printer doesn't support and re-enable after a successful connection is made.
