Nowadays, using fiber optic cables for internet speed up to Gigabit level is possible. Fiber optic cables were used back then which provided speed equal to 10Gbps (Gigabits per second). It was a technology that required home running of fiber optic wires from the ISP’s office to our homes. And this method was expensive as well as complicated, resulting in slower broadband speeds.
Currently, the most popular one among the top 4 ISPs is DOCSIS 3.1 modems. All these big companies including Cox, Spectrum and Comcast are providing customers with DOCSIS 3.1 compatible modem at an extra monthly fee along with their package plans. When you have your own DOCSIS 3.1 modem, you can save money every month because it does not require an extra fee to lease.

How We Tested
To determine the best DOCSIS 3.1 modems, we looked at a variety of factors. The most important factors were performance and compatibility.
To test the performance of each modem, we used the Netflix ISP speed index. This tool measures the average streaming speeds achieved by Netflix customers on different ISPs. We looked at the results for both download and upload speeds.
We also tested the range of each modem’s signal strength. For this test, we used an app called WiFi Signal Strength to measure the connectivity of the different modems from a distance of 25 feet.
We looked at how easy it is to install each modem and considered customer reviews, as well as feedback from third-party review sites such as PCMag and Tom’s Guide. We also took into account the availability of user manuals, installation kits, and other necessary accessories for each modem.
Things To Consider
When shopping for a new modem, there are three key factors to consider: speed, compatibility, and whether to buy a modem-router combo.
- Speed: Speed is probably the most important factor when choosing a modem. DOCSIS 3.1 technology allows you to enjoy faster speeds than ever before, so it’s important to make sure your modem can handle them. Most routers and modems can only handle a few megabytes (MB), but DOCSIS 3.1 modems can support gigabyte speeds. This means that you’ll be able to use more of the latest technologies, without experiencing lag.
- Compatibility: Compatibility is another important consideration when purchasing a new modem. Make sure your new modem is compatible with your internet service provider. Many modems include information about the providers they are compatible with in their product specifications.
- Standalone Modem or Modem/Router Combo: Finally, if you’re not interested in renting a modem from your internet service provider, you’ll need to decide whether to buy a modem alone or a combo modem-router. A standalone modem is likely to be more affordable than a combo, but you’ll still need a router to get super-fast speeds. On the other hand, modem-router combos usually come at a higher price tag, but you won’t need to purchase a separate WiFi router. To help you make the best decision for your needs, weigh the pros and cons of each option.
