The Motorola MB8600 is a DOCSIS 3.1 cable modem rated up to 6Gbps, and setting it up takes little effort. Reviewers liked the simple design and found performance reliable, though several noticed it runs hotter than competitors like the Arris SB8200 because the cooling is less effective. It supports WAN Link Aggregation and works with major ISPs including Comcast Xfinity and Cox. Anyone moving up to a Gigabit plan is the right buyer; anyone who cares about premium build quality or a cool-running box isn't.

  • — Capable of DOCSIS 3.1 standard with 6Gbps top WAN speed
  • — Simple setup process with clear status lights, per Dong Knows Tech
  • — Supports WAN Link Aggregation for improved connection, per MBReviews
