What Does 400 Mbps Mean?

400 Mbps actually means that your internet connection can transfer data at a rate of 400 megabits per second.

However, don’t confuse Megabits and MegaBytes. Because their use cases are so dissimilar. The size of any file is measured in MegaBytes/MB, whereas internet connection speed is measured in Megabits/Mb.

In this case, one byte equals eight bits. As a result, 400 Megabits equals 50 MegaBytes.

Because the abbreviations are nearly identical, people frequently mix up megabits and megabytes. As a result, they believe that a 400 Mbps connection means a download speed of 400 MB per second.

That, however, is incorrect. With a 400 Mbps connection, you can download (400/8)MB per second, or 50 MB per second.

Furthermore, the actual download speed can vary depending on server distance, network traffic, and a variety of other factors.

Is 400 Mbps Fast Enough For Streaming?

Yes, a 400 Mbps internet connection is more than adequate for streaming.

Streaming necessitates more bandwidth. Because the content you stream is delivered to your device from a server via the internet. As a result, it necessitates both low latency and faster speed. But how fast do you need to be to stream?

Actually, it is determined by the quality of the content being streamed. Here is a chart of the speed required to stream various content quality levels.

Content QualitySpeed Needed 
Standard Definition (480p)3 Mbps
High Definition (720p)5 Mbps
High Definition (1080)9-10 Mbps
Ultra HD/ 4K(2160p)25-35 Mbps

As a result, it is clear that 400 Mbps is more than sufficient for streaming at any content quality.

Furthermore, with 400 Mbps, you can stream on multiple devices simultaneously without buffering. To be more specific, you can stream 4k on 16 devices at 400 Mbps!

Is 400 Mbps Fast For Gaming?

Yes, 400 Mbps is insanely fast for any kind of gaming.

There is a widespread misconception that online gaming necessitates a higher bandwidth. However, this is not entirely correct.

Because, like streaming, online PC games do not transmit large amounts of data or render high-quality images or video over the internet. Only the console or player control data is sent over the internet. The graphics are rendered on your PC/dedicated device’s graphics card.

However, both download and upload speeds are critical for gaming. Because you send a significant amount of data while gaming. Furthermore, latency is critical in gaming. That is why, when playing an online game, you will notice different server locations and it is recommended that you select the closest server. But how fast do you need to be to play smoothly?

For PC games, 5 Mbps+ download speed and 3 Mbps+ upload speed with a latency of 50-100 ms are sufficient.

Cloud-based gaming, such as PlayStation or Xbox, requires more bandwidth than standard PC games. Because the rendering is performed on a cloud server, the data is transmitted to you via the internet.

As a result, 25-35 Mbps download and upload speed and 50 ms latency are required to play cloud-based 4k games smoothly. In this case, higher speed and lower latency equal smooth gaming.

So, with a 400 Mbps connection, you can clearly play 4k games on multiple devices and stream on multiple devices at the same time.

Best Router For 400 Mbps Buying Guide

If you’re looking for a 400 Mbps router for the first time, you might need some assistance narrowing down your options. We’ve put together a buyer’s guide to assist you. This guide will explain all of the important features of a router. These are the features or parameters to look for when purchasing a 4000 Mbps router.


After your ISP bandwidth, the most important factor for fast internet is your wifi speed. Because no matter how fast your connection is, if your router can’t handle the bandwidth, your internet will be slow.

As a result, try to buy a router with a faster speed than your bandwidth. Furthermore, a high-speed router can be useful for creating a personal LAN or for file transfer.

The good news is that all of the routers we tested can handle more than 400 Mbps.

Number of Wireless Bands

The number of wireless bands also has an impact on a router’s overall performance. There are three router bands available right now: single-band, dual-band, and tri-band.

For those who are unfamiliar, 5 GHz means faster and 2.4 GHz means longer range. A dual-band router is required to make the most of your 400 Mbps connection.

If you want to use a mesh router system, we recommend getting a tri-band unit. The additional 5 GHz band ensures a secure connection between the extenders and the router.


The range is the second most important consideration when selecting the best wireless router for 400 Mbps. Because if the router’s range is shorter than your house, you won’t be able to access high-speed internet from every room.

You must first determine the range.

  • Find the size of your house. 
  • Then, depending on the size of your home, add 500-1000 square feet. That’s the range you’ll need to cover your entire home.

Number of Antennas/Satellites

It’s a common misconception that router antennas are a gimmick. However, these antennas are a functional component of the router.

Because they send signals in all directions. Choose a router with more than three antennas.

Furthermore, if you need coverage in a specific area, simply tilt one or two antennas in that direction and you will have a good connection.

Furthermore, if you are selecting a mesh router for a multi-story home, try to select a router with satellites equal to the number of floors.

Ethernet Ports

A router with enough ethernet ports is required for a better internet experience. Because a wired connection always outperforms a wireless connection.

Furthermore, for better performance, important or non-portable devices should have a wired connection.

So, to determine the appropriate number of ports, determine how many of your devices require a wired connection and then add 2-3 to the total for futureproofing.

That is the exact number of ports required.


To keep up with the increased bandwidth and ensure a stable connection to all devices, your router should have a powerful CPU and plenty of RAM.

Because each connected device consumes a portion of your router’s CPU and RAM and competes with other devices for internet access.

So, if you have a lot of devices, try to get a router with a good CPU and plenty of RAM.

Built-In Security Features

When selecting a router, built-in security features and parental control should be prioritized.

Otherwise, you’ll have to spend a lot of money on VPN and antivirus subscriptions.

Furthermore, a router with built-in security will keep cybercriminals out of your home and workplace.

So, look for a router with built-in security features.

Frequently Asked Questions

How fast is 400 Mbps internet?

400 Mbps internet is the best option for lag-free browsing. It is approximately 40 times faster than traditional internet connections.

How Many Mbps Can My Router Handle?

Actually, this is determined by the model of your router. The bandwidth of your router can be found on the package it came in, or you can search the model on the internet and look for its speed.

This is the maximum bandwidth that your router can support. If it’s a gigabit router, it can handle speeds of 1024 Mbps or higher. Otherwise, the exact Mbps will be listed on the website or in the package.

Does Having 2 Routers Increase Internet Speed?

No, adding another router will not improve your internet speed. Because you will receive the speed that your ISP provides.

No router can change that. A second router, on the other hand, can improve device connectivity and the overall performance of your internet connection.

Does Router Speed Matter?

Yes, router speed does matter to some extent. Because a faster router can better handle your internet bandwidth. Furthermore, a faster router can improve file transfer speeds between your devices and aid in the setup of a better-performing LAN.

Most modern routers, on the other hand, are close to ten times faster than your ISP connection speed. So you don’t have to be concerned about speed.


You should now understand how to select the best router for 400 Mbps. If you don’t want to go through the trouble of comparing dozens of routers, choose one from our list. We have only included the best products so that you can have a pleasant browsing experience. These routers are suitable for a wide range of online activities, including streaming, online gaming, and web conferencing. We hope you find the right router model for you.
