Best DOCSIS 3.1 Modems For GIGABIT Ethernet In 2022 – [Ultimate List]

Remember the days when you went to an arcade, took out some quarters, and played Pac-Man for hours? Back then we would never have imagined that gaming would take the turn that it has over the last decade.

Today gaming is almost entirely online and has grown to such an extent that sizable amounts of money can be won for competitors turning it into a profession. This kind of profession requires some pretty robust technology behind it.

Besides gaming, amid a global pandemic, we have all learned pretty quickly how to work remotely. This has also required us to spend some time and money investing in better network solutions that support our daily online meetings and schedules.

Today we need a modem that will go the extra mile so that we can work or game in comfort. Let’s take a look at some of the best DOCSIS 3.1 modems.

Your Guide For Selecting Best DOCSIS 3.1 Modem in 2022


With technology evolving continuously, we do not want to buy today and be stuck tomorrow.

Many DOCSIS 3.1 internet modems are implementing what they call future-proofing protocols. This means that they are installing software and features that will be switched on as technology needs change. Check if your potential new buy supports this.


Typically you will find four Ethernet ports on a router modem. This allows for multiple direct-wired to connect to the network.

You also have the benefit of link aggregation which combines more than one port or link to increase the traffic flow capabilities.


In a day and age where security for your network I paramount, you need to investigate what security protocols your potential new device accommodates.

WPA and WPA2 are the latest security encryption protocol that is used to secure the data flowing on your network.


It makes sense that the more antennas you have the better your correlation between signal strength and speed.

However, the software behind the antenna is equally important. Specs such as MU-MIMO will better the transmission capacity of the router and allow for faster send and receive functionality.


Most modem router providers have apps that allow you ease of use from inception. This means that you can use the app right from the start when it’s time to set up, set usage limitations, monitor the speed that your network is running at, and even allow for guest network sign-ins.

An app gives you more freedom as it is also accessible remotely and can even give you alerts to potential risks.

When you are looking for a DOCSIS 3.1 router-modem combo, the size is a factor to consider. The space that the modem needs to go into will be affected by the size of the device.

Some modems are a lot bulkier than others and are more suited to bigger open-plan spaces. Before you choose, have a look at the space around where the device will go.


If your DOCSIS router-modem combo only needs to cover a small area then it’s relatively easy to choose one. but when you need a modem that will cover a bigger area with more obstacles, you need to think about its bandwidth.

Dual-band router-modem combos support 2.4 GHz and 5 GHz frequencies giving you more freedom to transmit data at better speeds.


Do you need a modem that will give you access to email and Facebook or that will give you flawless gaming and HD streaming?

It is important to know what you will be using the modem for so that you can tie that up with the features that the modem you choose offers.


The DOCSIS capability of a cable modem is the protocol that your ISP will use to provide you with the internet. The difference between DOCSIS 3.0 and 3.1 is the number of concurrent connections you can have and the speed at which they run.

DOCSIS 3.1 can provide speeds of more than 1 Gigabit which is very important if your intended use requires higher processing capabilities.


Firstly you need to check with your ISP as to what their capabilities are. It is pointless buying even one of the best DOCSIS 3.1 modem that your service does not support.

You will need to carefully compare what your service provider’s speeds are capped at before you invest in a modem that will complement those speeds.



All of us experience dust landing on every surface conceivable. Your DOCSIS 3.1 internet modem is no different. It attracts dust and if this gets into the interior of the router can start to cause problems.

It is recommended that you wipe your router down often with s damp cloth or a dust cloth. You can also tilt it to the side to blow out any excess dust that has accumulated inside.


Our modems tend to work hard for us especially during those peak times when everyone is gaming and streaming concurrently.

Remember to keep your modem free of obstacles such as papers and socks gone awry. It needs to be in a cool place that allows the airflow technology to perform properly.


Can you lubricate your modem’s internal parts? Yes, there is a dry lubricant spray that you can purchase which will allow you to keep your device running smoothly without damage.

You can also buy a special lubricant spray if you need to place your device in storage and do not want it to suffer internal damage.


Technical devices do not like the sun. Modems are no exception. If your modem is placed near a window, close the blinds or draw the drapes closed so that the sun is not shining directly on your modem.

Direct exposure will lead to the outer casing fading and distorting and the heat generated will make the device overheat and potentially cause internal damage.


1. Can I leave my modem on to cool down?

DOCSIS 3.1 modems can be bought off pretty much any store that sells network equipment. Cable modems are very common, but the problem with buying them online is that you get a much smaller range of products when compared to buying it online. Amazon is an ideal platform to get hold of some of the best DOCSIS 3.1 modems out there. Amazon gives you not only a much larger range, but also reviews, discounts, and an easy return policy.

If your plan supports a maximum speed of 600 Mbps but your DOCSIS 3.1 modem supports a maximum speed of 2.5 Gbps, you will still get speeds only up to 600 Mbps. This is something that you need to keep in mind while buying your modem.
