Overview

2x2 DOCSIS 3.1
32x8 DOCSIS 3.0

Response to a question on the Amazon page from MTRLC LLC (Motorola) dated

7/14/2017 says, "Model MB8600 and all Motorola products use Broadcom
chipsets and do not have the problem associated with the Puma 6 chipset."

Specifications

  • Four 10/100/1000 Gigabit Ethernet (GigE) ports allow connection of any SINGLE device with an Ethernet port including a router, Windows or Mac computer, HDTV, or game station.
  • The multiple Ethernet ports are NOT for connecting multiple devices; they allow connection to a router that can bond two Ethernet ports to achieve speeds over 1 Gbps when supported by your cable service.
  • Supports IPv4 and IPv6. Includes Broadcom full-band capture digital tuner to enhance speed and save energy.
  • Active Queue Management (AQM) significantly reduces Internet latency, much better than popular 32x8 3.0-only cable modems.
  • AQM results in faster page loads for all Web traffic and greatly enhances interactive applications like online gaming and video conferencing.
