If you are a professional who works from home, or have too many tabs open, or play games online, you understand how essential it is to have a good internet connection. If your computers are often starved of the internet, and you have decided to invest in a modem instead of wasting money renting one from your ISP, we suggest buying the modem that comes with DOCSIS 3.1 technology.
The DOCSIS 3.1 is a new technology which uses a cable interface for providing speeds up to 10 GB per second. The speed was previously only possible with fiber optic cables, this new technology brings blazing fast speeds to the door of every internet user.
Gigabit or Docsis 3.1 modems can ensure that there is never any lag in your online game and you can stream 4K videos on the go. It is also essential for people who work from home and don’t want to compromise their work because of slow internet. Of course, you can always rent a modem from your ISP – but that will cost you over the years and won’t be a high-quality one too. The best course is to simply get one for yourself.
Before getting it, you should make sure that your ISP supports the modem. To make it easier, we’ve mentioned the compatible and approved ISPs for the model we’ve listed in our guide. Additionally, in the table below you can also find out the ISPs which are not compatible.

What is DOCSIS 3.1?
The abbreviation stands for Data Over Cable Service Interface Specification. In order to make your cable system to work with a cable modem, this protocol is required. The Docsis 3.1 is the international standard used for transferring data over a cable TV system.
It is based on the latest digital technologies like LDPC encoding, support of QoS and low latencies, high modulation orders, and over 1 GHz of usable spectrum. The Docsis 3.1 has the ability to maintain backward compatibility and deploy it on an HFC network. Therefore, you don’t have to upgrade the plants.
With Docsis 3.1, you can get blazing speeds of up to 10 GB per second which were previously possible only with a fiber-optic connection. It is understandable why residential households prefer fiber optic connections, but all this is about to change with the introduction of DOCSIS 3.1.
With the introduction of this technology, cable service operators can meet the demand for high-speed connections and even rival the fiber optic market. Just using a DOCSIS 3.1 modem on one end cannot deliver high speeds, but if both ends of the connection are supported by the technology, it is completely possible to meet the standard set by fiber-optic companies.

If you don’t have DOCSIS 3.1 in your area, you don’t have to worry. The modem also has backward compatibility which allows it to work with Docsis 3.0 as well as 3.1 technology. It also supports IPv4 and IPv6 browsing standards.
The device is quite small compared to standard modem sizes. Since it comes with a Broadcom chipset, it runs fast and shows stable performance even with its small size. I used the device for nearly 3 months and it did not show a single drop.
There are some packet loss and heating issue with the device. When running for a long time, the modem can get hot enough to throttle download and upload speeds. In fact, the latency issues and packet loss are directly connecting to the overheating of the chipset.
To counter the problem, I ended up installing a small fan to keep the device running at room temperatures. Some users have also complained about the poor customer service and warranty replacement services offered by Arris. Since my unit worked perfectly, I didn’t get to check that claim, but I would keep that in mind when committing to the device.
Please note that the modem does not work with Verizon, AT&T, or CenturyLink.

One of my favorite features of this modem is that it comes with network expanding features. MU-MIMO support and native mesh support are integrated. However, if you are thinking of supporting more than 12 connections with this modem, it is better to invest in a device that comes with specialized support for such connections.
This Netgear modem is a great looking device, there is no doubt about that. It is shaped like a hexagon, and it looks pretty different and neat, even if the external design does nothing for the connectivity of the modem. However, without the stand, the modem struggles to stand upright.
It is highly recommended that you use the modem in its upright position. Of it is laid horizontally, it is highly likely that you will reduce airflow and may cause throttling of speed due to overheating.
The company provides this modem with 1 year of warranty and 3 months of tech support. After that, you will have to work with their web-based services for any issues you may be encountering. Although that is not a bad deal per se, it is also not a great one.

With twice the channel bonding capacity of other modems, this Netgear device is a highly recommended modem when it comes to Docsis 3.1 capacities. The company was the first to create modems that work with this technology, and clearly, it is still number one in this regard.
The CM1000 is one of the oldest and best products put forth by the company. It offers download speeds of 1.2 GB per second and upload speeds of 304 MB per second. If you are working with a 8 x 4 modem at the moment, you will notice a massive change in your browsing and streaming speeds if you get this device.
The back panel of this modem has a very simple and user-oriented design such that there is one Gigabit ethernet connection, one coaxial connection, a reset button, power input socket and the power switch. The intuitive design is brilliantly thought-out.
On the front, there are five indicator LEDs, along with an aluminium strip. As a result, the device looks extremely elegant and sophisticated. My only complaint with the device is that the indicator lights are very difficult to see from across the room.
The five LEDs are for power, downstream, upstream, internet, and ethernet. You should keep an eye on the power light – a red light indicates that the device is too hot and throttling of speed may occur due to the heat. If the downstream light is blinking, it means that the modem is looking for a downstream channel.
Upstream blinking is again, indicative of the modem’s search for a channel. If your internet light is blinking, the modem is syncing with the provider’s cable modem termination system (CMTS). A blinking green or amber ethernet light indicates that the Ethernet port is processing traffic.
Another thing to be noted is that unlike Arris, Netgear only offers one year warranty for its devices. You can connect with the support team using phone or email. You can also use live chat for getting information quickly. In my experience, working with the team was extremely easy and they resolved all my issues smoothly.

Differences between Docsis 3.0 and 3.1
When buying modems, DOCSIS is one of the most important features to consider. 3.0 and 3.1 are actually version numbers of protocols used by modems. The main difference between them comes down to the speed and number of channels you can use at the same time.
Some of the advantages of a DOCSIS 3.1 over 3.0 are highlighted as follows:
- Speed – as mentioned before, it is one of the major and perhaps, the only important features that consumers care about. When it comes to downloading speeds, there is nothing that can counter DOCSIS 3.1, because it offers speed up to 10 GB per second and upload network capacity of 1 GB per second.
- AQM – active queue management ensures that there is very little network delay because data traffic is handled at home network level. The result? No lag when playing games online, fast responses when engaging with other players, faster movie downloads, faster streaming, and graphics display at an even higher resolution.
- Increased capacity on existing networks: Docsis 3.1 also offers an increase in network capacity because it can transmit 50 percent more data over the same spectrum compared to 3.0 technology.
- Less energy wastage – active queue management also ensures that there is very little wastage of energy because of increased cable modem efficiency.
Ultimately, it all comes down to what your service provider can give you. If your ISP offers internet speed of more than 1 GB, you should invest in 3.1 modems. But if the average speed offers if less, DOCSIS 3.0 will do just fine.
Since these devices tend to cost upwards of $100, and a 3.0 modem only costs $50 – you should only invest in such devices if you are in need of speed like that.
Major Gigabit ISPs in the US
The network is one of the most versatile ISPs in the US, as it provides cable television, internet, and wireless services. XFINITY offers various packages and allows the user to choose according to their requirements. Therefore, it is very user-oriented and easy to customize.
There are XFINITY bundles you can choose from that combine both TV and internet. Internet speed is 150 Mbps in almost all of the bundles, which is sufficient for the average person. You can stream 4K videos on the go, and all the internet speed tiers are suitable for online gaming. Latency is not an issue when you game via this provider.
In 2017, it was also rated as the fastest internet provider by SpeedTest and Netflix. Advanced XFi gateways can give you the speed up to 1 Gigabit per second with XFINITY.
Spectrum Gig has offered gigabit speed to large enterprises for years and now it has offers for small and medium-sized firms. Spectrum Business Internet Gig delivers you a constant IP, remote network access to ensure you uninterrupted service even on the road.
In some regions, the plans of this ISP provide you a speed up to 940 MB per second. If you do not live in such area, rest assured – Spectrum internet speeds starting at 60 Mbps which is more than enough for a fast internet experience. Spectrum gig is one of the best ISPs for large homes with multiple connections who enjoy heavy internet activities.
It is the third-largest cable provider in the US delivering internet over coaxial cables. COX communications give you high-speed internet across 18 states. Cable and internet from COX are cost-effective for the average consumer as compared to other companies.
The ISP is a good option if you have a tight budget and need a reliable internet along with a decent cable TV. For small businesses, Cox offers a variety of plans ranging from internet speed of 25 Mbps to 300 Mbps. Each of these plans includes static IP addresses, online backups up to 25 GB, branded email addresses, along with security suite licenses which protect your computer from viruses and online threats.
Mediacom promotes TV and internet services starting as low as 40$. This bundle unlocks 60 Mbps of speed and 100+ channels. However, the modems provided by Medicom are mediocre, and most of the dropouts of service are a result of poor maintenance. Therefore, if you are on this plan, we highly recommend getting a brand-new modem.
A plan of 100/500 MB per second will provide you with the mentioned speed very consistently. There are slowdowns here and there but these only reduce speed 20-25%. In certain cases, downloading speed has been reported to be excellent but it is not very consistent for a prolonged time. Medicom also offers a Wifi mesh which helps to remove dead zones from the house.
Wow gives cheap internet plans in the south and the Midwest US. Internet packages go from 30$ to 80$ per month. Compared to other top ISPs, Wow is relatively cheap. Wow came 8th out of 67 ISPs in May 2018 as part of a survey conducted by Netflix. Uncapped data is the biggest perk of Wow. The maximum speed of Wow’s plans tends to fall above-average range.
To take advantage of its great prices, customers need to stick around for at least one or two years of service. Among current customers, the reviews are up and down. The quality of service largely depends on the consumer’s area. One can cancel the contract during the first 30-day testing period without any extra charges.
Ultimately, it all comes down to what your needs are when you think of buying a modem. The quality of experience with a DOCSIS 3.1 modem is definitely unparalleled. With over 10 GB per second speed, you will get to experience the smoothest internet experience of your lifetime.
All six models featured here are the best in their category. Arris has proved over and over again that the company has products that are reliable and worthy of trust. You can rest assured that this device will earn its hefty price tag with its unbeatable performance and easy to use set up.
