Nowadays the market offers a great variety of models so it may be difficult for you to find the best DOCSIS 3.0 modem that will deliver high speed. The top models feature similar technical characteristics, however, they are compatible with different ISPs. I have compiled this list of the eight greatest DOCSIS 3.0 modems to help you select the most appropriate one.

The ARRIS SURFboard SB6190 is a modem that can work with numerous USA ISPs. The only providers it does not support are ATT, Verizon, CenturyLink, DSL and Fiber.

This model has 32 downstream and 8 upstream channels. This is an optimal solution for the users who are subscribed to 600 Mbps speed plans. Besides, by buying a modem, you won’t need to pay the rental costs each month.

Thanks to DOCSIS 3.0 support, this model is 16x speedier than 2.0 devices. It can work with a great variety of USA Internet companies, including Comcast XFINITY. However, it does not allow using your cable service as your telephone provider.

Speed: 400 Mbps | Connectivity: ethernet | Features: Certified for Xfinity, Spectrum, Cox, 16 downstream & 4 upstream

The Arris SURFboard AC1900 is probably the best DOCSIS 3.0 modem, as it does not only ensure a stable and reliable Internet connection but is also compatible with almost all major USA Internet providers. It would be a great option if you are using an Internet plan with speeds of up to 400 Mbps.

Besides, the installation process is quite easy. Maximize Internet speeds with this 16x4 cable modem, Wave 2 AC1900 Dual Band Concurrent Wi-Fi Access Point and a router with four Gigabit ports.

To choose the best DOCSIS 3.0 modem, you need to pay attention to the number of download and upload channels. Take a closer look at the unit, and you will see such numbers as 16x4, 24x8 or 32×8 that define the number of channels a modem can access. The greater this number is, the speedier connection the device can deliver. With DOCSIS 3.0 support, this speed is even faster.

If your Internet company only offers sixteen download channels in your region, there is no need to buy a 24×8 modem, as it won’t improve the connection. The number of channels your ISP offers should match the number of channels supported by a modem.

If a company offers speeds that range from 100 to 300 Mbps, opt for a modem with sixteen downstream and four upstream channels.

If your ISP provides a speed higher than 300 Mbps, I advise you to purchase a 24×8 or an even more advanced modem. The models that I have selected for you are great for any plan up to 600 Mbps.

When subscribing to an Internet plan, make sure to select the one that offers the necessary downstream speeds for fulfilling your everyday tasks. Your task is to choose a DOCSIS 3.0 modem that can handle those speeds for the best possible performance.
