The SURFboard S33 is a DOCSIS 3.1 cable modem. It uses DOCSIS 3.1 technology to provide ultra-high-speed internet access on your home or small business network.
For whole-home connectivity, you can use the Ethernet port on your S33 to connect a Wi-Fi router (separate purchase). To use the second Ethernet port, you will need a second IP address. Please contact your service provider for assistance.
Note: For Cox customers, a second IP address is not supported on the Residential service.
Using the connection capabilities of the S33, you can connect your computer and other network-enabled devices via the two Ethernet ports. The S33 connects to the existing coaxial cable connection in your home. The S33 will not work with DSL, Fiber to the home, or satellite internet service.

Let’s get started

A.Connect the coaxial cable (not included) from the able wall outlet or RF splitter to the Cable connector on the rear of your S33.
