My HP Deskjet 2700 won't connect to my Wi-Fi network. What troubleshooting steps should I take?

First, ensure your Wi-Fi network is functioning correctly. Restart your router. Then, put the printer into Wi-Fi setup mode (usually by pressing and holding the Wi-Fi button on the printer). Use the HP Smart app to search for and connect to the printer. Double-check that you're entering the correct Wi-Fi password. If problems persist, try temporarily disabling your firewall or moving the printer closer to the router.
