2.5 Gbps DOCSIS 3.1 Cable Modem (CODA56), Single Port, Xfinity Spectrum Cox
- This modem is designed exclusively for use with coaxial cable internet connections (the round cable with a screw-on connector). It is not compatible with fiber optic, DSL, satellite, or 5G home internet services. Even if your provider is Xfinity, Spectrum, or Cox, you must confirm you are subscribed to their cable internet service, not their fiber service. Please verify your wall connection type before purchase.
- This device functions solely as a modem, providing one Ethernet port to connect to your cable line. It does not include built-in WiFi, voice/telephone capabilities, or routing functions. To connect multiple devices wirelessly, a separate WiFi router is required.
- It delivers multi-gigabit performance, supporting internet plans up to 2.5 Gbps via its 2.5 Gbps Ethernet port. It is optimized for plans of 1 Gbps and higher from certified providers like Xfinity, Spectrum, and Cox. Please verify your plan speed and provider compatibility.
- Setup requires: (1) An active coaxial cable internet service (not fiber), (2) A separate WiFi router with a 2.5 Gbps port to achieve the full speeds, and (3) Contacting your ISP for activation. Without a router, you can only connect one device using the included single Ethernet cable.
- Featuring DOCSIS 3.1 technology with low latency, it is optimized for smooth 4K streaming, online gaming, and video calls. It remains backward compatible with DOCSIS 3.0 networks.
