The front of your 5G Gateway has five lights: one power and four signal indicators. Review the PDF to get all info related to the lights on your hub.

  • Green (solid): The number of lights indicates your signal. If you only have one or two green lights, you should check for a better location.
  • Amber (chasing): Your gateway is looking for the best signal tower.

    • One (E004): No IP address
    • Two (E400): SIM error
    • Three (E403): Authentication failure
    • Four (E013): DNS down
    • Off: If all signal indicator lights are off and the power button is red, there’s no connection to the 5G cellular network (E405).
