To connect your HP DeskJet 3722 printer to Wi-Fi, first put the printer into wireless setup mode by pressing and holding the wireless button for about 3 seconds until the wireless light starts blinking. Then, on your laptop or smartphone, open the HP Smart app, add a new printer, and select your DeskJet 3722 from the list to connect it to your Wi-Fi network. You will need to enter your Wi-Fi password (case sensitive) during the setup[1][3][4].
If you have changed your internet provider or Wi-Fi network, you may need to reset the printer’s network settings before reconnecting it to the new Wi-Fi. This can be done by following instructions in the HP Smart app or using the WPS push button method if your router supports it. However, sometimes WPS may not work, and the manual Wi-Fi setup via the app is preferred[1][5].
Steps in brief:
1. Turn on your printer.
2. Press and hold the wireless button for about 3 seconds until it blinks.
3. On your phone or computer, open HP Smart app.
4. Add a printer and select your DeskJet 3722.
5. Choose your Wi-Fi network and enter the password.
6. Complete the setup as prompted.
If connection problems persist, ensure the printer and device are on the same network and restart your devices[1][4].
