Motorola B12
Score: 83/100Rankings

The Motorola B12 is a compact DOCSIS 3.1 cable modem delivering up to 2.5 Gbps downstream with QoS and LED indicators, perfect for multi-gigabit internet plans. Its single Ethernet port and lack of built-in Wi-Fi mean you'll need an external router for multiple devices. Best suited for users who already own a high-performance router and want a future-proof 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.
