Gaming, especially competitive gaming, has become increasingly popular through the years. When it comes to gaming, you can never have too much internet speed. Internet is used for both having low latency/pings, as well as being able to download patches and updates in a breeze.

400 mbps is an excellent speed for gaming, however something that should be noted is that download speed is not directly correlated with a low latency. Download speeds will help to a degree, but the MS of your internet service is what heavily affects your ping in game. If you have fiber optic internet, you can expect ping below 15ms.

If your service is not pure fiber optic, then you can expect ping anywhere between 20-40ms. A ping well under 100ms is generally preferred for the smoothest gaming experience possible.

If Wifi is your primary connection point, then we recommend using a high speed gaming router to help keep your as low as possible. Click here to check out the wide selection of Netgear Wifi Gaming Routers on Amazon.

Is 400 Mbps Worth It?

You will still be able to browse the internet, game, and watch 4K streams, but you will have a much lower bill.
