Arris SURFboard SBV3202
Score: 71/100Rankings

The Motorola MT7711 is an all-in-one DOCSIS 3.0 modem, AC1900 Wi-Fi router, and two-port Xfinity Voice solution. Its 600 Mbps speed ceiling and Xfinity-only certification restrict its use for higher-speed or non-Xfinity services. Best suited for Comcast customers needing integrated voice and Wi-Fi.

The ARRIS SURFboard SBV3202 is a DOCSIS 3.0 cable modem designed for Xfinity Internet and Voice, offering up to 800 Mbps download speeds and a built-in firewall with battery-backup support. It lacks Wi-Fi, uses an older DOCSIS standard, and provides only a single Ethernet port, limiting future-proofing and multi-device wiring. Best suited for Xfinity subscribers needing VoIP lines on modest-speed plans.

Products in the top-left offer the best value (high score, low price).

Professional reviewers commend the MT7711 for its straightforward, sub-15-minute installation and the value of an all-in-one modem-router-phone solution tailored to Xfinity customers.
Everyday users praise the quick plug-and-play setup, reliable Wi-Fi coverage for multiple devices, clear VoIP calls, and the savings from consolidating three devices into one. Common complaints revolve around the 600-Mbps speed ceiling, occasional activation reboots, limited 2.4 GHz range in larger homes, and the fact that the unit only works with Comcast Xfinity services.

Professional reviewers and editors describe the SBV3202 as a solid, budget-friendly option for Xfinity customers who need reliable wired connectivity and VoIP support. They commend its easy setup, LED indicators, and battery-backup feature, but caution that the older DOCSIS 3.0 standard and single Ethernet port limit its longevity and multi-device use.
Everyday users generally appreciate the modem's ability to hit advertised speeds and its space-saving mounting options, especially when paired with a separate router. However, many express frustration over its provider-specific compatibility, lack of Wi-Fi, and the perception of outdated technology, resulting in mixed overall satisfaction.
