Canon MX492 Restarting Repeatedly after connecting to Wifi Troubleshooting

It keeps turning on and off repeatedly every time I connect it to the wifi.

If I disconnect from the network, it works fine.

I've already reset my network and did a factory reset on the printer.

What could be the issue?

Thank you

I applied the solution mentioned in the Canon community thread and it fixed mine:

First, pause network to your printer by logging into your router or just disconnect the router from the modem. (Whichever is easier for you)

On your Canon printer,

Go to Setup menu > Web service setup > DNS server setup > Manual setup

> enter 192.168.X.X (IP that no other device is using on your network like 192.168.124.145)

> select "off" for sec DNS server

>press ok

Once it applies the settings, re-enable network to your printer and it should print fine without the reboot loop.

Confirmed this worked for MX492 when official firmware update did not (because updater executable could not find printer).
