Buying Guide for the Best DOCSIS 3.1 Modem

For starters, you should never make the mistake of buying a used modem because if you do so, the modem will still be connected with the previous owner and his internet setup. So instead of wasting your money there, you should be ready to spend a little extra and get a DOCSIS 3.1 cable modem that brings you your desired results.

Here are a few important factors to consider when trying to find the best DOCSIS 3.1 cable modem for your exceptional internet connection needs;

ISP Compatibility

The very first thing you need to do is to confirm that your internet service provider is supporting the DOCSIS 3.1 technology in your area or not. You won’t be able to activate your modem if it’s not compatible with your internet service provider, which means that you’ll just be wasting your money here.

Signal Range

When looking for a combo that serves you both as a modem and as a router, you are supposed to consider the signal range offered. The signal range tells how much area it covers, and you also need to consider the number of devices that it can support all at the same time. The latest Wi-Fi technology is 802.11ax, but that can be quite expensive for you, so if you opt for a reasonably priced modem, then even the 802.11ac technology will be enough for you.

Security

Considering the WEP and WPA/WPA2 wireless security protocol is a must when you are looking for a modem that also serves as a router. Following this security protocol means that no random user or hacker can enter your network.

Price

Lastly, price is an important factor to consider, and when it comes to DOCSIS 3.1 cable modems, they can be quite expensive, so you better decide on a budget before time. If you want something cheaper, then the NETGEAR CM1100  will be the best one as it gives you the option to use different plans.

DOCSIS 3.0 vs 3.1

Whenever you are buying cable modems, the most important feature that you need to consider is that of the DOCSIS. As far as DOCSIS 3.0 and 3.1 are concerned, they are version numbers assigned to two different protocols.

The DOCSIS 3.1 cable modem efficiency is better than the 3.0 version, and due to the queue management technology, less energy is wasted and consumed. This is one of the biggest differences between the two DOCSIS versions.

2-Speed

DOCSIS 3.1 offers a downloading speed upto 10GB, and its uploading speed is 1GB per second, which is exactly what users look for nowadays.

3-DOCSIS 

3.1 comes with active queue management, which is probably the one difference and reason why people opt for this version instead of 3.0. With active queue management, you won’t have to worry about any lags or delays when streaming HD content or playing games. It will be a seamless and smooth experience due to no or very little network delay.
