Motorola MB8600 Ultra-fast DOCSIS 3.1 Cable Modem

Get your own cable modem and save on monthly modem rental fees. The Motorola MB8600 is a great choice for customers who want ultra-fast cable modem performance both today and for years to come.

The cable modem is designed to work with U.S. cable Internet providers including Comcast XFINITY, Comcast Business, and Cox Communications. It supports ultra-fast DOCSIS 3.1 and also falls back to the fastest DOCSIS 3.0 32x8 speeds, great for smooth video streaming, fast downloads, high-speed gaming, web browsing, and more. For maximum flexibility, it’s also backward compatible with DOCSIS 2.0 and 1.1 services. It includes DOCSIS 3.1 Active Queue Management (AQM), which accelerates page loads, gaming, and video conferencing. Other highlights include advanced surge and lightning protection, easy installation, superb customer support, and more.

  • The MB8600 supports ultra-fast DOCSIS 3.1 - the only cable modem standard that can deliver speeds over 1 Gigabit per second (Gbps)*. It also has 32x8 support for the fastest possible speeds using the older DOCSIS 3.0 standard. Even if you don’t have DOCSIS 3.1 service now, you can benefit from the 32x8 DOCSIS 3.0 capability that’s also built into this cable modem.
  • The MB8600 supports Ethernet Port bonding which is essential for delivering 1 Gbps and higher speeds, and comes support for the fastest available cable modem services. It delivers blazing-fast upstream speeds of up to 1 Gbps and downstream speeds of up to 3.8 Gbps when supported by your cable service speed and a router that can bond Ethernet ports.
  • Active Queue Management (AQM) significantly reduces Internet latency. AQM results in faster page loads for all Web traffic and greatly enhances interactive applications like online gaming and video conferencing.
  • The MB8600 includes Broadcom Full-Band Capture digital tuner to enhance speed and save energy.
