Score: 74/100
Motorola MB8600
Score: 82/100Rankings
The Motorola MB8600 is a DOCSIS 3.1 cable modem delivering up to 3.8 Gbps downstream speeds and four Gigabit Ethernet ports. Its lack of built-in Wi-Fi and masked Ethernet ports limit flexibility for some users. Ideal for gigabit plans where a separate router is already in use.
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.

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 view the MB8600 as a solid, no-frills DOCSIS 3.1 modem that excels in raw speed potential and low-latency performance thanks to its Broadcom chipset and AQM.
Consumers generally praise the MB8600 for delivering consistent gigabit-class speeds and an easy setup with major ISPs. Common praise centers on its stability and the ability to handle multiple static IPs, while recurring complaints focus on the hidden Ethernet ports, occasional distance-related speed loss, and the need for an external router due to the absence of Wi-Fi.
“"valuable" frill-free DOCSIS 3.1 modem ideal for 1 Gbps plans”
“"Reliable high speeds (e.g., 900+ Mbps down at 20 ft in tests, stable for gigabit plans)"”
