Explore here 5 Best Modem Router Combo for Xfinity (Comcast), Spectrum, or Cox internet based on DOCSIS 3.1 technology. Most of the cable internet providers like Comcast Xfinity, Spectrum, Cox, and CenturyLink are providing the gigabit internet plans. Cable providers have started rolling out DOCSIS 3.1 nationwide. With new DOCSIS 3.1 cable modems it is now possible to get Gigabit Internet speeds on your existing Cable connection.
In order to connect devices to the internet, a modem and a router are required. A modem connects your device to your Internet Service Provider (ISP) and receives information from them. From there, a Wi-Fi router distributes the signal to other devices through wire or wireless, allowing them to connect to the same network.
In the past, it was necessary to purchase the two separately. Advances in technology have made it possible to fit both into one machine, known as a modem router combo. There are many different cable modem router combos (DOCSIS 3.1) in the market; each providing a different set of features and specs. Making informed purchases can help consumers save money and improve their internet speed.

Gigabit internet plans may be costly, but the high speeds make it worthwhile for avid streamers and online gamers. One way to mitigate this cost is by ditching your rented networking equipment and providing your own gigabit modem and router.
If your endgame is Gigabit-speed Internet, then you will have to upgrade to a DOCSIS 3.1 modem sooner or later. The main benefit of this technology is that its max downstream caps out at 10 Gbps and its upstream caps out at 2 Gbps. Gigabit speeds are offered by the nation’s largest ISPs, including Comcast Xfinity, AT&T, Cox, CenturyLink, and Google Fiber. If you live in a metropolitan area, you are probably in one of these networks.
What is DOCSIS Cable Modems?
DOCSIS (Data Over Cable Service Interface Specification) is a technology developed by CableLabs for transfer of data over coaxial cable that are deployed and used for cable TV connection. Cable operators across the world have adopted DOCSIS standards in Cable Modems for providing internet data, voice and video services using existing cable TV systems.
DOCSIS 3.1 offers a huge jump in download and upload internet speeds over DOCSIS 3.0, supporting up to 10 Gbps download and 1 Gbps upload speeds. Using DOCSIS 3.1, Comcast is offering Gigabit and Gigabit Pro Internet service with 1 and 2 Gigabit download speeds.
