To reconnect your HP printer to WiFi, you can use the printer’s Wireless Setup Wizard if it has a touchscreen, or use the HP Smart app on your mobile device to guide you through the process. The basic steps are:

1. On the printer, go to the Wireless or Network settings menu.
2. Select **Wireless Setup Wizard** or similar option.
3. Choose your WiFi network from the list.
4. Enter the WiFi password.
5. Wait for the printer to connect to the network.

If your printer does not have a touchscreen, you can alternatively:

– Press and hold the Wireless button and Cancel button simultaneously until the printer restarts and the wireless light blinks to enter setup mode, then connect via the HP Smart app[1][4].

– Use the HP Smart app on your smartphone or tablet: open the app, tap the plus (+) sign to add a printer, then follow on-screen instructions to connect it to WiFi[1][5].

– If needed, connect the printer temporarily to your computer with a USB cable, run the HP software or app to configure the wireless settings, then disconnect the USB cable after setup[5].

Additional useful tips:

– Make sure your printer is within range of your WiFi.
– Verify the wireless button on the printer shows a stable blue light, indicating connection; flashing means it’s not connected yet[2].
– If your printer supports WPS, you can use the router’s WPS button to connect without entering a password manually[1][3].
– After successful connection, print a test page to confirm.

These approaches cover most HP printer models and are detailed in the official HP instructions and videos for 2024[1][3][5].
