ARRIS SURFboard SBV2402 DOCSIS 3.0 Cable Modem - Xfinity Voice Ready

Our review of the ARRIS SURFboard SBV2402 finds it best for households that want to stop paying modem rental fees while keeping Xfinity Internet and Voice service. The bottom line: this is a straightforward DOCSIS 3.0 modem with telephony ports and a 1 Gbps Ethernet port, approved for Xfinity plans up to 800 Mbps. Setup is simple via the SURFboard Central App and a router is still required for Wi-Fi, so it fits users who want reliable wired speeds and integrated voice without paying monthly rental charges.

Key Features

• Save Money: Owning the modem reduces or eliminates monthly rental fees, lowering your cable bill over time.
• DOCSIS 3.0 Technology: Provides a reliable, broadly supported cable standard that delivers fast internet to home devices on approved plans.
• Xfinity Voice Support: Two telephony ports let you keep existing phone service through your provider without separate adapters.
• Easy Activation: Plug in the modem, use the SURFboard Central App, and follow the steps to activate with your ISP for a simple setup.
• 1 Gbps Port: A single gigabit Ethernet port allows a fast wired connection to a router or single device for maximum throughput.

Who It's For

This modem is ideal for renters or homeowners on Xfinity Internet and Voice plans who want to avoid ongoing rental fees and need reliable wired speeds up to the provider-approved maximum of 800 Mbps. It suits users who have or will add a separate Wi-Fi router, since the SBV2402 provides the modem and telephony functions but not built-in Wi-Fi.

It is less suitable for those seeking a modem-router combo with integrated wireless, or households that already subscribe to speeds well above the 800 Mbps approval, where a DOCSIS 3.1 modem would be a better long-term choice.
