What are the benefits of using my own cable modem?

Owning a certified DOCSIS 3.1 modem lets you manage your network through the Nighthawk app or browser. Mid/high-split unlocks faster uploads, plus OFDMA for steadier peak-hour speeds.

Do I need a WiFi router with this modem?

Yes. This modem has no built-in WiFi. Pair it with any WiFi router or mesh system, such as a NETGEAR router or Orbi. Wired devices connect directly to the modem's Ethernet ports.

Do I need to activate with my ISP after setup?

Plug in the modem, then contact your ISP with the MAC address on the bottom label to activate. Xfinity self-activates via app; Spectrum and Cox can activate by phone.

What is mid/high-split?

Mid/high-split is a cable network upgrade that unlocks faster upload speeds. Availability varies by ISP and region. Without it, uploads are limited to standard DOCSIS 3.0.

Will this work with my home phone or bundled voice plan?

This modem does not support telephone service. A bundled voice plan such as Xfinity Voice will not work with your existing home phone. Contact your ISP for compatible equipment.
