Failed to connect to the wireless router Canon Pixma MG7720

[Pixma7720]

- I switched to a new Internet Provider and got new router.

Company: Quantum Fiber

Router model: C5500XK

- Firmwares: Both Router and Printer are up to date with firmwares

- Issue: During printer wireless setup, printer finds my Wifi name, I select it, but it errors out with "failed to connect to the wireless router" I have tried everything, including resetting everything in the printer, but nothing works. Called Quantum fiber, Tech support says their router can automatically pick up all frequencies 2.4, 5GHz etc, and since everything else is being connected in my home with 2.4 and 5Ghz, that the issue is not them, that it is Canon. 

I can connect printer via LAN and Direct print, but not wirelessly. I was able to connect before with (through WPS button) but the new router does not have a WPS button or a code available. My printer is a sitting duck and I need help please, thank you.

Hello!

Try running this on one of the computers on your network: https://canon.us/MG7720Setup 

It should uninstall the Canon software, re-install it, and pair the printer to your new network.

Greetings,

The C5500XK is an ONT/Router.  It does not have wireless capability.

Are you using it in conjunction with a WiFi360 or your own device?

Quantum offers different pods WiFi 6 or WiFi 7.  According to the Quantum site the pods should not be mixed.  Both are backwards compatible with WiFi 5 and 2.4Ghz.  

The MG7720 supports 2.4Ghz wireless and WPA2 /AES encryption.  The first thing to do is confirm the new wireless is properly configured to support these standards.  Often new devices come preconfigured to utilize the same SSID name for all broadcasting networks and in many cases are configured to use WPA3 encryption (only).  

After some digging, I found this information about their WiFi7 pods.  

Their WiFi7 pods have good specs.  They may however be preconfigured to use WiFi3.  Use the Quantum App to check. 

See if there is a WPA3/WPA2 or WPA2.  See my example.

The other thing you can try is (if supported) giving each broadcast and unique name (example) MyHouse2.4, MyHouse5, MyHouse7 and connect the printer to the 2.4 Ghz broadcast.  You can also temporarily disable all but the 2.4Ghz band, make the connection and then turn the others back on.  

Stephen's recommendations are spot on, but if the Quantum wireless is not configured to support the printers requirements (2.4 & WPA2) its not going to connect.

The same will apply if you are using your own wireless hardware in conjunction with the C5500XK.  🙂
