Ranked #5 in Best Standalone DOCSIS 3.1 Cable Modems

Motorola MB8611

2.7

The Motorola MB8611 is a DOCSIS 3.1 modem offering fast internet speeds with a 2.5Gbps Ethernet port and support for up to 32 downstream and 8 upstream channels. Tech Reviews called it a great modem with backward compatibility and AQM for low-latency performance. However, some users have reported firmware-related stability issues, particularly with version 21.3.7, leading one user to switch to an Arris S34 after prolonged problems.

This modem is ideal for users seeking high-speed internet but may not be suitable for those requiring voice capabilities or who experience firmware instability.

Strengths

— 2.5Gbps Ethernet port for high-speed wired connections
— Fast DOCSIS 3.1 speeds with support for 32 downstream and 8 upstream channels
— Backward compatible with DOCSIS 3.0
