Score: 74/100
Arris SURFboard SBV3202
Score: 71/100Rankings
The NETGEAR CM1000 is a DOCSIS 3.1 modem delivering up to 1 Gbps download with IPv6 and QoS support. Its single Ethernet port and top-heavy chassis are trade-offs. Ideal for gigabit cable users who already have a separate router.
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.

Professional reviewers consider the CM1000 a reliable and straightforward DOCSIS 3.1 solution that delivers fast gigabit speeds, broad ISP support, and useful features like IPv6 and QoS. However, they caution about its unstable base and the limitation of a single Gigabit Ethernet port despite the high theoretical bandwidth.
Consumers generally appreciate the modem's consistent high-speed performance, easy setup, and cost savings from avoiding rental fees, but they frequently mention the top-heavy design that can tip over and the absence of built-in Wi-Fi as drawbacks.
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 However, many express frustration over its provider-specific compatibility, lack of Wi-Fi, and the perception of outdated technology, resulting in mixed overall satisfaction.
