Connecting a Router to an ONT

Details

This information is intended for customers with Cox Internet service delivered to the home with fiber via an Optical Network Terminal (ONT) who are using their own router. You will know if you have fiber service based on your order confirmation email which will state you have an ONT, or information provided by a Cox representative.

We've installed your ONT already. Now it's time for you to connect your own third-party WiFi router so you can get online. Let's get started by reviewing some useful information.

  • To get Internet service in your home, a standalone WiFi router is required. You'll need to connect your router to either the Ethernet port on the ONT or an Ethernet jack on the wall.
  • Your router will broadcast WiFi or you can connect devices via Ethernet cable. For the best performance, we recommend a Gigabit Ethernet router with WiFi 5 or higher.

Note: WiFi modems are incompatible with the ONT.

Finding the ONT

We've installed your ONT in one of a few places depending on your home and property type. The ONT is labeled Alcatel-Lucent, Nokia, or Calix. Use the table below to determine which scenario fits your household best, and then click the link to open a connection guide.
