Arris SURFboard SBV3202
Score: 71/100Rankings

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.

The Netgear Nighthawk CM2050V is a DOCSIS 3.1 modem with integrated Xfinity Voice, supporting up to 2.5 Gbps and dual telephone ports. Its exclusivity to Xfinity Voice and single 2.5 Gbps Ethernet port limit broader use. Perfect for Xfinity Voice subscribers who need high-bandwidth and voice integration.

User feedback is sparse; the only cited rating is a 4-out-of-5 star review on Netgear.com, indicating generally positive reception but lacking detailed praise or criticism.

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 However, many express frustration over its provider-specific compatibility, lack of Wi-Fi, and the perception of outdated technology, resulting in mixed overall satisfaction.
