To troubleshoot connectivity issues with your HP Tango printer, start by ensuring it's properly connected to the Wi-Fi network. Check the printer's Wi-Fi indicator light and restart both the printer and your router if necessary. Verify that your device is connected to the same network as the printer. Update the printer's firmware and ensure you have the latest version of the HP Smart app or software installed on your device. Resetting the printer's network settings or reconfiguring the Wi-Fi connection may also help.
