Score: 75/100Rankings
The ARRIS SURFboard SB8200 is a DOCSIS 3.1 cable modem delivering very high theoretical speeds and dual Gigabit Ethernet ports. It lacks built-in Wi-Fi and can run hot, with some users experiencing lag spikes and port issues. Best suited for households that already have a separate router and need a high-performance wired modem.
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.
