Tr4500 won't reconnect to WiFi after router change.

Having been on a copper wired router I've gone fibre optic and I've managed to get everything back except my  printer. Using the app from my phone it suggests pushing the button that Has two interlocking "c's" (not sure what the correct name is) and then following the  instructions on the readout. All the instructions say is about the paper size, and nowhere to put in the router password.  What do I do now please?

Greetings,

While manual set up is possible, Wireless connection and configuration updates are easier to perform using a cable and the printer's set up software.

Keep in mind the printer is only capable of connecting to a 2.4Ghz wireless broadcast which supports WPA2 security.

You sent a link for mac, I think. I'm on Windows 11.
