  • Compatible with all major cable internet providers: Including certification by Xfinity by Comcast and COX. Not compatible with Spectrum, Verizon, AT&T, CenturyLink, DSL providers, DirecTV, DISH and any bundled voice service.

The primitive cable technology has a limit of speed that it can provide, therefore, fibre-optic cables were developed, which are capable of delivering unprecedented speeds but at a much higher cost.

What if I tell you that now it’s possible to get speeds up to 10 Gbps using your old coax cable. I know you won’t believe me, but it is true and several customers have shifted to this technology since its introduction.

DOCSIS stands for Data Over Cable Service Interface Specification and its 3.1 version is the latest one around, and it is 10x faster than its predecessor, 3.0.

DOCSIS 3.1 is the latest international standard that makes it possible to transmit high-speed data using a traditional coax cable TV system.

But wait! To get the benefit of this standard you need a modem that can work on this standard. So, for a starter, you should say goodbye to the modem provided by your ISP, because most probably it won’t be DOCSIS 3.1 modem.

Secondly, you need to make sure the modem you are going to buy is compatible with your ISP and they can deliver high-speed internet as well.

So, are you ready to say goodbye to the old rented modem and replace it with your own DOCSIS 3.1 modem?

Before reviewing the details of the best modems, the following section points a few factors that you should consider before buying one of the best DOCSIS 3.1 modem.

Best DOCSIS 3.1 ModemFactors To Consider

The first and foremost thing to consider is whether your local ISP supports DOCSIS 3.1 technology or not? Because if they are not supporting it then there is no use in getting any of the best DOCSIS 3.1 modems we have listed in this article.

Secondly, although the DOCSIS 3.1 standard can support up to 10 Gbps, different modems have an upper cap at a lower data transfer rate. For example, some modems may support up to 6 Gbps, while others only up to 2 Gbps.

Thirdly, the number of GigE ports the modem has will come in handy if you don’t have a separate Wi-Fi router at your place. In such a case you have to attach each device via GigE port to this modem to access the internet.

However, it is recommended to use a LAN-hub or a Wi-Fi router that is connected to the modem and all devices are connected to that router.

Review and Features

With ARRIS SURFboard SB8200, you can get high download speeds and low lag.

The ARRIS SB8200 can bring you the much-desired gigabit internet speed in a smaller form factor and with a reliable connection service. Moreover, one of its best features is that it is compatible with most of the major US internet service providers (ISPs).

  • The modem is great for cable connections that can provide up to 2 Gbps internet plans.

However, the catch is that it cannot support 2Gbps directly as it outputs the internet through its two 1Gbps Ethernet ports. These ports support one Gigabit of connection individually, and you have to contact your ISP to assign you a second IP to be used in parallel with the first one.

Furthermore, tt uses the Broadcom BCM3390 chipset to outperform the older variants. There are also LEDs in the front that give out the modem status and provide a visual indication about the internet connection.

The ARRIS SB8200 provides a reliable connection so you have to restart your modem less and have access to high-speed internet for 4K streaming and faster upload speeds. The 32×8 channels allow for a higher bandwidth connection so you can connect more devices in parallel without the fear of throttling down the internet speed.

The two Ethernet output ports can be used to get a combined speed of up to 2 Gbps. The modem is docsis3.1 so the hardware inside it supports up to 10Gbps connections, but the output limits to around 2Gbps.

Let us list a few worth mentioning features of the ARRIS SURFboard SB8200 Do below:

  • Easy setup and reliable operation.

  • 32×8 downstream/upstream channels.

  • Up to 2 Gbps internet speed support.

Check Price from Amazon

Review and Features

The NetGear Nighthawk CM1150V delivers fast Gigabit internet speeds with voice connection support.

The NetGear CM1150V is certified by Comcast by Xfinity for the high-speed internet and voice bundled packages. However, the downside is that this device is not compatible with Verizon, AT&T, DSL providers, or other non-Xfinity voice services.

In terms of internet speeds, it can support data plans of up to 2 Gbps, however, the actual speed depends on the ISP and the data plans you select. It works with almost any wifi router, so connectivity is not a problem.

The voice phone works with Xfinity voices services to provide you with call features such as call forwarding, conference calling, and caller id. Additionally, up to two telephones can be connected through the two telephone ports included in the modem.

Furthermore, the CM1150V supports Xfinity internet plans of up to 2 Gbps for 4k streaming and HD online gaming. Two ports can be aggregated to enhance the connection to 2Gbps. The modem also works seamlessly with any wifi router. Moreover, DOCSIS 3.1 with 32×8 channel bonding and ODFM 2×2 ensure high-speed connectivity with multiple users.

While the overall performance in terms of internet connectivity is as good as you can get on the NetGear Nighthawk modems, we feel like the non-compatibility with other ISPs is a big downside. Then again, this was design to be compatible with Xfinity, and if you are using the service, it is going to be a good upgrade over the DOCSIS 3.0 modems.

In short few worth-mentioning features of the NETGEAR Nighthawk CM1150V are as follows:

  • Bundled voice package support for Xfinity by Comcast.

  • 2x phone lines that can be connected with Xfinity voice services that offer caller id, conference calling, and caller id.

  • Simple and easy to establish connection and wifi setup.

  • Up to 2 Gbps internet speed through link aggregation.

  • DOCSIS 3.1 with 32×8 channel bonding and ODFM 2×2.
