Best Cable Modem Buying Guide

Top 5 Best Cable Modems 2020 Tested Reviews & Guide 16

Here are the facts and features that you need to consider when purchasing the best internet modem on the market. Read on this modem buying guide to pick the best from above reviews section.

Who Should Buy A Cable Modem?

A cable modem is a must-have a product if you want to work efficiently from home or at the office using cable internet. Without a modem, it becomes hard to connect or get a stable & speedy internet as you have to do the settings every time.

However, many service providers, for the sake of retaining customers, gives you the option of renting a cable modem. When you rent a cable modem from them, you must pay a monthly fee in return. It is a good option until you are ok with basic settings and want to use the modem only for 2-3 months.

On the contrary, if you want to buy a modern and fastest cable modem, we will recommend you purchase one for yourself. It also becomes a good option if you want to use the modem for long as you will save on rent.

How to Buy The Best Cable Modems 2020?

How to Buy The Best Cable Modems 2020 -

So, you know, agree that it is better to buy a custom cable modem for you with the settings that you need. Thus, we will now learn what the best settings are and what features you must consider before buying the best cable modem for you.

ISP compatible

The first and foremost thing to consider before buying your best cable modem is to check whether it will support your ISP or not. If you are ready to purchase one, you must check the official site of your ISP. They usually display a list of the cable modems that their service supports. You must buy among those options to make sure you won’t be guilty in the future.


Another very critical factor to consider is the number of channels your modem supports. A channel usually means downloading and uploading channels of the internet. The more is better as it gives you more options to connect.

When you are buying a cable modem, you must know how many channels your ISP is offering. If your ISP is offering just 24 downstream channels, then 32 by eight modem will be useless for you. They are usually in options like 16 by 4, 24 by 8, or 32 by 8.

You must check the number of channels with your ISP and purchase the same cable modem. In this way, you will get the most out of your internet channels.


Though less important, the design also plays a vital role in selecting your Wi-Fi router. This factor is less critical than others. However, you must know where you want to keep your modem, and the shape must allow it to stay there.

Ethernet Ports

These ports have gained more importance than they deserve. An ethernet port is one that will allow a connection between a modem and your internet devices. The more ports mean, the more devices you can connect with the internet.

People always prefer to buy a cable modem that has so many ports. However, in reality, we just use one or two ports at a time. So, if you are getting a good modem with fewer ethernet ports, then you must not hesitate to buy it.


A modem will usually come with a 1-3 year warranty from the provider while most of them have the standard one year warranty. A warranty plays a crucial role in your purchase as any problem during this time will mean that your provider company will sort it for free. When you are buying the best cable modem, you will want to get some sort of security, and here the warranty becomes important.


Most regular modems come at a price between 60 to 80 bucks. The best ones with top speed internet come at a price of over 150 bucks. We know that more price is usually better, but things are slightly different in cable modems.

A modem with a medium price might prove enough in your case. In rare cases, you might need the most expensive router. So, an ISP might guide you the best about the modem that you need.


The best cable modem must not heat very fast. Usually, cable modems will come with high operating temperatures. So, you must know how much your modem will heat and buy the same.


Last but not least is the internet speed that your router offers. Usual routers will come with speeds of up to 100 to 300 MBPS. Most ISPs usually offer you speeds less than 100 MBPS. In this case, it is useless to purchase a modem that promises you very high speeds. On the safe side, you will get most modems with speeds of up to 300 MBPS.
