What is the DOCSIS 3.1 modem?

Internet transmission comes with technologies that enhance performance. One of these technologies is Data over Cable Service Internet Specification (DOCSIS 3.1). DOCSIS stands for Data Over Cable Service Interface Specification and is simply a way to transfer data over your home network via cable lines rather than through WiFi or phone lines like DSL does.

The main advantage that comes with DOCSIS 3.1 is that it has more compatibility and delivers excellent speeds. DOCSIS 3.1 allows for much faster transfer rates than previous versions (DOCSIS 1-3), but to take advantage of that speed, you need to have both a modem capable of supporting those high speeds as well as an ISP that supports them (and not all do).

When looking for gigabit plans, they, therefore, make the ideal choice. Without ignoring the fact that there are few DOCSIS 3.1 modems, many are designed for a specific purpose, and those are limited to particular ISPs. It may therefore be very hectic for you to get the best modem.

Do I need DOCSIS 3.1 Modem?

Cable companies are rolling out new modems that support speeds up to 10x faster than DOCSIS 3.0, but is it worth the investment?

The short answer is yes! If you want fast internet at home or in your office, upgrading to a DOCSIS 3.1 modem will give you the fastest and most reliable cable service available today! Here’s why -Faster Speeds – Up to 10x faster download speeds than DOCSIS 3.0 (up to 1 Gbps) means less time waiting for pages and files to load online and more time doing what you love on your computer or smartphone!

According to Comcast, who was one of the first companies out with products using this technology, they offer to access up to 10 Gbps download speeds (which would allow you to download an HD movie in less than 30 seconds)

Must haves for a DOCSIS 3.1 Modem

A DOCSIS 3.1 modem must have the following features to ensure they serve your home well. These features were all analyzed as we were carrying out our tests to identify the best modems. They include:


As mentioned above, a DOCSIS 3.1 modem is supposed to support gigabit internet speeds. However, not all modems are made the same. Therefore, it is important in this day and age to ensure that you get a modem that can serve gigabit speeds in your home or office.

Therefore, choose a DOCSIS 3.1 modem that can adequately serve higher speeds than what you are currently getting from your ISP. This will ensure that you get an exceptional service now and into the future.

Compatibility with your ISP

Why would you want to choose a modem that is not compatible with your ISP? Compatibility with your internet service provider is one of the most important features to check in a modem.

Several modems are universally compatible while others are compatible with a few ISPs. Therefore, as part of our duty in reviewing the modems, we identified the ISPs that each modem is compatible with.

For example, you need an Xfinity modem since it is compatible with Xfinity if it is your ISP.

Channel bonding

Every modern modem should have channel bonding. This is a technology where two radio channels that have different frequency bands are intertwined to give you enhanced bandwidth. This enables your modem to handle multiple and demanding internet activities.

We have reviewed all the modems and indicated your choice if they support channel bonding. This feature will ensure that your DOCSIS 3.1 modem serves your smart home perfectly.


Online hackers, malware, phishers, and other threats have become more pronounced these days. Therefore, you need a modem that can enable you to tackle these challenges every day.

Several modems and router combos have advanced security features to ensure your data and family are safe from threats. These features are as described for each modem that we have reviewed.

In addition, you also want to pick a DOCSIS 3.1 modem or router combo that automatically updates the security features and the main firmware. This will ensure that you are protected from the latest security threats available on the internet.

Ethernet ports

A good DOCSIS 3.1 modem or modem router combo should have several Ethernet ports. For a modem, having at least 2 Ethernet ports will go a long way in ensuring that your wired devices get the internet connection they need.

This is because one of the ports will be used to connect the router while the others can connect devices such as printers, gaming machines, computers, and laptops for a stable fast connection.

Of note is that you should choose a modem with Gigabit Ethernet ports. These will ensure that your devices get the fastest internet connection.

Finally, it is good to check as an addition, if your modem has USB ports. These will also enable you to connect storage devices where needed.

What is the difference between a 3.0 and 3.1 modem?

The latest DOCSIS standard, DOCSIS 3.1 is capable of 10 gigabits per second (Gbps) download speeds and 1 Gbps upload speeds. However, the most widespread DOCSIS standard that can be found in many homes today is DOCSIS 3.0 which allows for 32 channels to download data simultaneously at one time as well as over 1 Gbps download speed capacity. The first version has slower internet capabilities compared to its newer counterpart, but it may still work just fine depending on your needs!
