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 CM1200 is a DOCSIS 3.1 desktop modem with integrated Wi-Fi 6, four Gigabit Ethernet ports, and USB 3.0, supporting up to 2 Gbps download via link aggregation. While it provides extensive connectivity, it still relies on a separate router for advanced networking and lacks 2.5 Gbps Ethernet ports. It fits power users who need high-speed wired and wireless performance on gigabit-class plans.
