Performance, compatibility, and real‑world use

This refurbished unit is approved for use with major U.S. providers such as Comcast Xfinity, Cox, and Charter Spectrum, among others.

Installation is straightforward: plug in the device, install the SURFboard Central App, and follow the guided steps to activate and personalize your network. The companion app offers real‑time visibility into connected devices and simple parental controls to manage screen time. The four gigabit ports help keep wired devices performing at their best, especially during peak usage times when wireless bandwidth is in high demand.
