Best DOCSIS 3.1 Modems Reviews in 2022

DOCSIS 3.1 is the latest standard of technology on which the new-gen modems are based. Thanks to this latest DOCSIS 3.1 version, the new-age modems are capable of delivering reliable and fast internet speeds up to 10Gbps.

While most ISPs out there are still offering plans up to 1Gbps only, you can switch to a DOCSIS 3.1 modem as its future-proof and works better than any DOCSIS 3.0 modem that you might be using these days. Hence, if you are interested in buying a new DOCSIS 3.1 modem, we have picked up several good options from the market on the basis of these few aspects such as:

  • Max-supported Internet Speed: The most important factor of all that an individual should check in a modem is its max-supported internet speed. As you might already know, DOCSIS 3.1 is a standard that supports up to 10Gbps internet speed, yet there are no ISPs that offer such high-speed plans. So, you should pick the one that matches your internet plan’s speed. Hence, if you have a 1 Gbps plan, you can definitely pick a 1Gbps DOCSIS 3.1 modem as well, it’ll work great for you.
  • Compatibility: As you might already know that most ISPs out there install their own modem while you subscribe to their internet connection. However, the rental fees they charge you for that is too much. Therefore, if you are deciding to install your own modem, you should check if your modem is compatible with your current ISP or not. Otherwise, you will have to change it.
  • Design and Build quality: Apart from the technical specs, the design and the build quality of the modem also matter a lot. If you look at the design of any old modem, they look quite hideous. However, most of the new-age modems come with attractive designs and also offer wall-mounting options as well.

Similar to these factors, there are several things that a buyer should consider while looking for a new DOCSIS 3.1 modem. For the beginners out there, we have also included a detailed buying guide in this article below that will help everyone to pick the best suitable DOCSIS 3.1 modem for themselves. Hence, if you feel confused to make your final decision, you can also take help from the Buying Guide. Until then, let’s quickly check out the list of best DOCSIS 3.1 modems that we have shortlisted for you.

We can easily understand that you are just another tech-enthusiasts like us who like to be around all the latest technologies and use the best available products in the market. That being said, in case you want to experience the best and fastest internet speed, it is a must to switch to the newest DOCSIS 3.1 standard modem.

We have already discussed some of the best DOCSIS 3.1 modems in this article so far. Hence, you can simply check out their features and pick the best suitable one that suits your internet plan. In this buying guide, we will be discussing all the important factors that one can consider checking before buying. Therefore, if you have no prior knowledge about DOCSIS 3.1 modems, make sure to read this buying guide until the end.

1. Max Supported Internet Speed

Without a doubt, a modem based on the latest DOCSIS 3.1 technology will definitely offer you a better internet speed. As compared to its predecessor DOCSIS 3.0 technology, DOCSIS 3.1 is capable of delivering internet speeds up to 10Gbps. While the DOCSIS 3.0 is only capable of handling up to 1Gbps.

With that said, if you have a DOCSIS 3.1 modem, the doors to subscribing to much better internet plans open up for you. However, there are barely any ISPs out there that offer a better internet plan than 1Gbps. However, DOCSIS 3.1 is better in terms of connection stability as well and is also future-proof. So, in case your ISP provides an internet plan that delivers more than 1Gbps speed, you should pick the right modem that suits your requirements and budget.

2. Compatibility

As we discussed earlier, there are not many ISPs out there that offer internet plans with more than 1Gbps internet speed. Meanwhile, most of the ISPs recommend you to install their modem for which they charge your monthly rental fees. Thinking about it wisely, you can save a lot of money in the long run if you install your own modem as they are not usually that expensive.

However, there are some ISPs that don’t provide their internet services to people who have a third-party modem. Therefore, while you pick a new DOCSIS 3.1 modem for yourself, make sure that the modem is compatible with your ISP. Otherwise, you will have to change your internet service provider to use that modem.

3. Gigabit Ports

While checking the specifications of the DOCSIS 3.1 modem that you like, make sure to check for the number of gigabit ports present on the modem. While some DOCSIS 3.1 modems only come with 1 Gigabit Ethernet port, there are several options available in the market which offer up to 4 Gigabit ports as well. With multiple ports, there’s an opportunity of using link aggregation to get double internet speed on a wired network.

4. Design and Build Quality

Checking the specifications of a DOCSIS 3.1 modem is definitely an important task. However, you should not forget to compare the modems on the basis of their design and build quality. These days, the new-gen modems come in quite a stylish design that will look aesthetic with your computer setup. Unlike the older modems which were too hideous, the new ones that come these days are quite attractive. Moreover, several DOCSIS 3.1 modems even come with a wall-mount design that will make it easier for you to keep your setup cleaner and do better cable management.

5. Warranty

When it comes to cable modems, there are only a few brands out there in the market that are ruling the entire industry. We have tried to include multiple modem options from all the top brands of the industry. Hence, you don’t necessarily have to worry about the build quality of the modems that we have listed on our list. Not just that, all the top brands in the market also offer either 1 or 2-year warranty for their modems as well which is always a plus point for the customer.

FAQs about DOCSIS 3.1 Modem

1. Is DOCSIS 3.0 outdated these days?

Ans. Even though we have DOCSIS 3.1 technology as the latest, the DOCSIS 3.0 standard is still in use and not yet outdated. The reason is that the majority of the ISPs offer internet plans up to 1 Gbps speed only which DOCSIS 3.0 can easily handle. So, at the current moment, DOCSIS 3.0 is also usable. But, as soon as any ISP starts to offer better plans, you will not be able to subscribe to them, that is why upgrading to a DOCSIS 3.1 modem is future-safe.

2. Does DOCSIS 3.1 modems offer better internet speed?

Ans. If you compare both DOCSIS 3.0 and DOCSIS 3.1 technologies, you will find that DOCSIS 3.1 simply offers better connection stability. It is because DOCSIS 3.1 is designed to handle more data traffic, and offer better upstream and downstream data with more efficiency.

3. Do you need to upgrade to DOCSIS 3.1 modem for using a Wi-Fi 6 Router?

Ans. Although you can simply use your Wi-Fi 6 router with your older DOCSIS 3.0 modem as it will work just fine as long as you have a 1 Gbps internet plan or lower. However, if you want better internet speed, you will need to subscribe to a better internet plan for which DOCSIS 3.1 modem is a major requirement.

Conclusion

Although DOCSIS 3.0 modems are still usable and work great, if you still want to improve your internet experience, upgrading to a new DOCSIS 3.1 modem will be a great choice. Even though you are not using a high-speed plan of more than 1 Gbps at the moment, upgrading to a DOCSIS 3.1 modem will still show great improvement as it highly reduces the latency and makes your internet connection more stable and reliable.
