Conversely, the send light pertains to the modem’s ability to send upstream signals to the ISP.

  • A solid green send light assures proper transmission.
  • A flashing green light suggests that the modem is in the process of seeking an upstream connection.

1.3 Online Light

The online light is your confirmation of a successful connection to the internet.

  • A solid green light indicates that your modem is online and ready for action.
  • A flashing green light suggests that the modem is still in the registration process with the network.

1.4 2.4 GHz Light and 1.5 5 GHz Light

These lights relate to the Wi-Fi functionality of your Arris modem.

  • A solid green 2.4 GHz light signifies the operational status of the 2.4 GHz Wi-Fi radio.
