Ranked #4 in Best Standalone DOCSIS 3.1 Cable Modems

Motorola MB8600

3.0

The Motorola MB8600 is a DOCSIS 3.1 cable modem offering up to 6Gbps speeds with a straightforward setup process. Reviewers noted its simple design and reliable performance, though some observed it runs hotter than competitors like the Arris SB8200 due to less effective cooling. It supports WAN Link Aggregation and works with major ISPs including Comcast Xfinity and Cox. This modem is ideal for users upgrading to Gigabit plans but may not suit those seeking premium build quality or minimal heat output.
