Here's a quick summary of the key benefits you'll get from Docsis 3.1 technology:
For you to benefit from this technology, you'll need to invest in the best Docsis 3.1 cable modem. Although you can rent a modem from your cable provider, having your own modem will help you save a lot of cash in the long run. Plus, you'll get a chance to pick a high-quality modem that meets your unique specifications.
There's more into Docsis 3.1 modems than the ability to support the latest DOCSIS 3.1 technology. The modems feature varying capabilities and performances.
Your ability to pick the perfect modem for your needs will dictate how well you can enjoy the goodies that come with the newest doses 3.1 technology.
Let's take you through some key considerations to help you get the right modem for your internet needs.
The number one thing to look for in a cable modem is whether it will work with the cable internet provider of your choice.
If you buy a modem that doesn't work with the cable provider in your area, it will be a waste of money as you won't be able to activate it. Always make a point of going through the list of compatible modems on your ISP website before making a choice.
Manufacturers of these modems also a list of ISPs their products can work with. For instance, most units we have featured on this list work with the major cable providers and are labeled the best Docsis 3.1 modem for cox, infinity, Comcast, spectrum, etc.
Additionally, check that the ISP you plan to work with offers a gigabit internet package to ensure total compatibility.
You'll also need to pay attention to how many Ethernet ports a cable modem comes with. This is crucial as it dictates how many devices you can connect to your modem for fast wired connections.
Most Docsis 3.1 modems feature 1, 2, or 4 Ethernet ports. If you go for a modem featuring 1 port, you'd want to use it with a router to connect more devices.
Some modems, mostly those from Netgear, feature link aggregation to allow you to use half the total number of the ports available to make even faster gigabit Ethernet connections.
Apart from compatibility, you should also check your internet plan. Why is this necessary? It's simple…if you go for a modem designed to offer high levels of internet speeds, but your internet package doesn't support that speed, then it means you won't be able to enjoy the full benefits of your modem.
As you might have noticed from our outline of the top-rated modems above, a good number of them can support gigabit packages of up to 2Gbps. And subscribing to a corresponding package is the surest way to enjoy these crazy speeds.
You can also come across a unit featuring a cable modem and router, all in one box. Such units are worth considering as they help you cut the cost of buying separate devices and also eliminate the clutter that comes with connecting multiple devices.
The only downside of these combos is that they might be easily upgradeable, unlike a separate router and modem. Whether to get a combo unit is a matter of personal preference.
Weighing the upsides and downsides of each will help you make a more informed decision.
A cable modem that comes with a Broadcom chipset enhances the security of your network in that it offers protection from denial of service (DoS) attacks.
If you go for a modem with a router, then you should also ensure the router supports WEP and WPA/WPA2 wireless security protocol to prevent unauthorized users' access.
At first, you can get easily intimidated by the high costs that come with most of the Docsis 3.1 modems on the market. But the truth is, you don't need to spend hundreds of dollars to get a high-performance modem.
You can take your time to look for models within an affordable range that have great performance and loads of positive feedback from previous users.
An example if the Netgear CM1100, which is quite an affordable way to let you enjoy the gigabit internet plans.
The two common types of Docsis technology you'll come across include Docsis 3.0 and 3.1. The latter is the latest version and a predecessor of the former.
Both technologies enjoy wide usage today, so it's important to understand how they compare to each other.
|Docsis 3.0||Docsis 3.1|
|Key improvement||Enhanced capacity, IPv6 implementation, and channel bonding||Increased speed, efficiency OFDM, progression, wideband channel|
|Date of issue||2006||2013|
|Downstream capacity||Up to 1Gbps||Up to 10Gbps|
|Upstream capacity||Up to 200Mbps||1-2Gbps|
|Channel bonding||8×4, 16×8, 24×8, 32×8||32×8|
From this quick comparison table, we can see that there are noticeable differences between the two technologies.
The right technology to choose, however, will depend on your unique needs and preferences.
For instance, if you live in a big city and you use the internet for normal things like watching movies on Netflix, checking mails, browsing the web, etc., then Docsis 3.0 will meet your needs. It might be a bit slow when downloading large files, but this won't be a deal-breaker for you. You can even stream movies in H.D. using Docsis 3.0.
However, the 3.0 compatible modems can only handle speeds below 1Gbps. And this brings us to our next question…
Well, in this case, a Docsis 3.1 modem will be a great option for you. This technology is ideal if you require high bandwidth for demanding tasks such as online gaming, fast internet on multiple devices, 4K ultra-HD media streaming, etc.
As we have mentioned above, one of the major considerations when choosing a new Docsis 3.1 modem is ISP (Internet Service Provider) compatibility. This is because different modems are only compatible with specific cable internet providers.
With that said, there are some popular cable providers in the U.S. that work with the majority of the cable modems on the market today.
These providers include:
Cox makes our list as one of the most popular cable providers for gigabit internet plans in the U.S. The company is known for its highly reliable cable internet and stretch their services across 18 states.
The ISP offers cost-effective plans and is a viable option if you're working on a tight budget and need reliable cable internet.

To take advantage of their affordably priced plans, you'll need to stick around for at least 1-2 years of service.
According to previous customers, the quality of Wow! internet mainly depends on your area of residence.
In case you're not satisfied with their services, you can always cancel the contract within a 30-day testing period without paying a cent.
We also have Mediacom Cable as another major cable internet provider in the U.S. This ISP has plans starting as low as $40 for a speed of up to 60Mbps and 100plus channels.
One thing to note about Mediacom, however, is that they provide mediocre cable modems. So, if you go with this ISP, your best bet is to get your own modem.
You can also access a 100/500Mbps plan to offer you the mentioned connection speed at a constant rate. You might experience slowdowns along the way, but this reduces the speed by around 20-25%.
Mediacom ISP also offers you WiFi mesh functionality to help get rid of dead zones in your home.
If you're using the services of a cable internet provider, then you'll need a Docsis 3.1 as it supports gigabit download speeds. But in the case of fiber, you don't need Docsis 3.1 as fiber internet only works with fiber optic specific modems.
If your ISP offers internet packages of over 1Gbps, then a Docsis router a worthy investment for you. If your ISP doesn't support Docsis 3.0, you'll also find the Docsis 3.1 modem as the only cable modem option available for you.
Yes. One of the key aspects of Docsis 3.1 technology involves Active Queue management, which helps minimize traffic congestion and keep the latency minimal, speeding up your streaming, gaming, and other tasks.
Absolutely! The Docsis 3.1 modems are backward compatible with Docsis 3.0. this means that if your ISP doesn't support Docsis 3.1, or you have no access to the same in your area, your new cable modem will still work using Docsis 3.0
Sure! There are Docsis 3.1 cable modems that come with built-in routers. If you want to save space and reduce technology clutter in your home, you can go for this combo. If you want to save money spent on buying separate devices, you should also consider a combo unit.
These numbers simply describe the number of downstream and upstream channels a modem comes with, in that order. A modem with 32×8 means it has up to 32 downstream channels and up to 8 upstream channels.
Say no to renting your cable provider's rental modem again! Getting your own cable modem helps save on rental fee while letting you choose a modem that meets your unique internet needs. Having outlined the best-performing Docsis 3.1 cable models on the market today in this guide, we've no doubt that you'll have an easy time identifying the best Docsis 3.1 modem that works with the ISP of your choice.
