I've successfully connected my HP 2700 to Wi-Fi, but now I want to change the Wi-Fi network it's connected to. How do I do that?

You'll need to forget the current Wi-Fi network and reconnect to the new one. Access the Wireless settings on the printer's control panel. Look for an option like 'Forget Network' or 'Clear Wireless Settings'. Once the old network is forgotten, you can then use the Wireless Setup Wizard to connect to your desired Wi-Fi network.
