If your HP printer won’t connect to Wi-Fi, you can fix the issue by restarting your printer and router, verifying Wi-Fi network name (SSID) and password, and reconnecting the printer to the correct Wi-Fi network using the Wireless Setup Wizard on the printer’s control panel[1][3][4].

Key steps include:

– **Restart both the router and printer** by turning them off, waiting about 30 seconds, and powering them back on to resolve temporary connectivity issues[1][3].

– **Ensure your computer and printer are on the same Wi-Fi network**, and you have the correct network password[1][3].

– **Use the printer’s control panel to reconnect:**
– Navigate to Setup or Network Settings.
– Select Wireless Setup Wizard or Wireless Settings.
– Choose your Wi-Fi network from the list and enter the password[1][4].

– **Check the wireless indicator light on the printer:**
– No light or blinking indicates not connected.
– A stable blue light means the printer is connected[2].

– If problems persist, **reset the printer’s network settings**, then reconnect to Wi-Fi[3].

– Consider **reinstalling the HP Smart app** on your computer or device to ensure proper communication between printer and network[3].

Following these steps typically resolves most Wi-Fi connectivity problems with HP printers[1][3][4].
