The Very Best Gigabit Modems for Blazing Fast Internet Speeds

Working from home (the norm with Covid-19), with far too many tabs, videos, Zoom calls, and the odd game or two running throughout the day, means that my computers are often stretched for internet speed. Additionally, living in a condominium with more and more people working from home means that our regular, run-of-the-mill internet speeds will soon become far less than what we need to ensure our working speeds remain the same. This is why many are turning to gigabit modems. If you can relate to the above, or perhaps you are experiencing this in your physical office, read on.

 

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.

Gigabit Modem Common Question and Answers

  • Q: Why is my gigabit internet so slow?
    A: It can be a couple of things. First, can your modem handle your speeds? Second, can your router handle speed. Generally speaking, it’s going to be one of those two things that are slowing your speeds down. If you have ruled both of those things out, your next step is to contact your ISP and see if they can do some testing.

 

  • Q: How do I know if my Ethernet cable is gigabit?
    A: Most likely you will have a Cat5E or Cat5 that’s been around for a long time and can handle gigabit speeds. You should see some writing on the cable itself or if that fails look to make sure it has 4 twisted pairs (Orange, Green, Blue, Brown) in the cable.
