Does My Cable Modem Need DOCSIS 3.1

March 17, 2022

If you need the fastest Internet connection you can get to support your devices and online activities, then you need a cable modem that supports DOCSIS 3.1.

Most Cable Internet Service Providers, like Comcast XFINITY, need an approved XFINITY cable modem.  You cannot buy any old cable modem and expect that it will work with XFINITY service.


When to Choose DOCSIS 3.1

When choosing a cable mode that is right for you, there are a few things to consider in your decision.  You should consider a certified DOCSIS 3.1 cable modem if your home network Internet usage and activities demand fast and reliable connections all of the time.  We have also covered what to avoid when choosing a cable modem.

If any of the following apply to you, DOCSIS 3.1 is your best bet:

You are an avid online gamer.
If you are a gamer, you need a reliable, fast connection to reduce lag. DOCSIS 3.1 technology delivers ultra-fast Internet because it is capable of 10 gigabits per second (Gbps) download speeds and 1 Gbps upload speeds.

You work from home.
Just like with online gaming, working from home requires consistent connectivity that is constantly reliable. DOCSIS 3.1’s ability to deliver extremely fast speeds and enhanced Internet performance is perfect for supporting video conference calls.

You or the kids in your home attend school online.
Online school requires reliable, fast connection for online classes and to avoid any dropped connection during important homework and exams. No risk in losing work when your connection is rock solid.

You enjoy video streaming.
Who among us wants buffering? No one. Get consistent video play without buffering with a DOCSIS 3.1 cable modem.

You have a lot of people in your home connecting to the Internet at the same time.
If this is your reality, you need a reliable cable modem that can support a robust home network, enabling your router to support everyone connecting at once.

DOCSIS 3.1 technology is a standard that your Cable Internet Service Provider has within their own networks.  When you connect your own DOCSIS 3.1 cable modem, it’s able to harness the true benefits of DOCSIS 3.1 technology, which is extremely fast speeds and higher data performance.

Even if your ISP is not using DOCSIS 3.1 in their network (check your ISP’s website or contact them before purchasing your cable modem), you can still use a DOCSIS 3.1 cable modem since its backwards compatible with DOCSIS 3.0.  We cover the difference between DOCSIS 3.0 and DOCSIS 3.1 in this article.  That means that you will still experience the benefits of faster performance today, and when your ISP offers DOCSIS 3.1, you will be able to get the fastest Gigabit speeds offered. Think of it as future-proofing your Internet connection.

Hitron’s CODA DOCSIS 3.1 Cable Modem is available on Amazon,  The CODA has DOCSIS 3.1 to deliver the fastest Multi-Gigabit speeds to your connected devices.  Learn more about cable modems or cable modem routers by reading Hitron’s ​Learn Page​.
