Connecting a Panoramic Wifi Gateway to an ONT Ethernet Port


Use the steps below to help you connect your Panoramic Wifi Gateway to the Ethernet port on the ONT when your ONT is in one of the following places in your home.

  • In a bracket mounted to an inside wall.
  • In a plastic media panel. Most plastic media panels have a shelf for the Panoramic Wifi Gateway.

Check the ONT to confirm it is plugged in to power and that the following lights are solid green.


Note: If the lights are not solid green, then contact us to help you get set up.


Locate the Ethernet cable that is visible from the ONT.

Note: If there is no Ethernet cable visible from the ONT, then remove the faceplate. Depending on the ONT, either slide down the faceplate or pinch the sides to lift off. Then connect the Ethernet cable to the Ethernet port on the ONT and then re-attach the faceplate.

Do not touch the thin fiber cable or the connector in the PON or WAN port on the ONT. Lasers are in use, and serious eye damage could occur.


Connect the other end of the Ethernet cable into the designated port on the Panoramic Wifi Gateway. The port varies based on the gateway version, so use your gateway color listed below to determine the port.

  • Black gateway (CGM4141COX): Use the ETH1 port.
  • White gateway (CGM4331COX): Use Ethernet port 4 marked with an orange line on the bottom right. This is the 2.5Gbps port. No other Ethernet ports on the back will work with the ONT.

Plug the power adapter into the Panoramic Wifi Gateway and electrical wall outlet.

Result: During connection, the LED light at the top of the Gateway will blink. After about 10 minutes, a solid white light indicates that the Gateway is online and ready to use.


Set up the network name (SSID) and password. Refer to Using a Single WiFi Network Name and Password.

Note: If you have Cox Voice service and a Panoramic Wifi Gateway, you can connect the phone cord in the telephone port on the back of the gateway as follows by model.

  • Black gateway (CGM4141COX): Use TEL 1.
  • White gateway (CGM4331COX): Use Telephone Port 1 on the top left side for the first line of Cox Voice service.
