Changing wi-fi

I need to change the Wi-Fi at my home to a different Wi-Fi. I tried going to “Device Settings” and selecting “Update Wi-Fi Network”. I get a message “Searching for your iro …” and nothing is ever found. I am not sure what to do from this point. Should I delete the device and start over?

It should fall back to the old wifi, try power cycling.
Is this gen 1 or 2

@JShearerii Here are the instructions for Gen 1

and Gen 2
