The Very Best Gigabit Modems for Blazing Fast Internet Speeds

Do you want to experience blazing-fast internet speeds at home? Do you want to stream, game, download, and upload without any interruptions? If you answered yes, then you need a gigabit modem. A gigabit modem is a device that can handle internet speeds of up to 1 Gbps (gigabit per second) or more. In this article, we will help you find the best gigabit modem for your home network.


So What are Gigabit Modems?

Gigabit Modems are routers that utilize DOCSIS 3.1, which is a new tech that allows internet speeds up to 10 gigabits per second. Until now you would have needed fiber cable to reach those speeds. What was once used only in large buildings have now become ‘mass-produced’ for residential users who are seeking to obtain faster internet speeds.


Why You Need a Gigabit Modem 

I find that these devices are primarily valuable to people, who work from home and require a fast internet speed, those who love gaming (e-gamers!), and more. You also want to buy your own modem, because even though you can rent one from your ISP, buying your own gives you more control and is cheaper in the long run.


How to Install a Gigabit Modem 

Typically, you will need to plug in your internet line and then call your Internet Service Provider (ISP) to register it with them. Each modem can have its own configurations and settings you may want to play with, and then you connect your router to the modem and you should be up and running.


How much does a Gigabit Modem cost? 

The devices I have included on this list range between $50 to $300. Considering you might be making your living from online work, investing in great equipment and speed from your IPS is a good thing to consider.
