An internet speed of 400 Mbps isn’t the fastest but it is “great” for gaming, streaming, working from home, and a lot of other activities. But is it ideal for you? Can it handle all the devices at your place? Let’s find out!

400 Mbps is equivalent to 400 Megabits per second. Therefore, you’ll get a download speed of 45-50 MB/s, as web browsers display download speeds in Megabytes.

Just so you know, it is faster than the average connection speed in the US. Hence, for online gaming, Netflix, YouTube videos, Instagram, Skype, Zoom calls, or even downloads, this speed is fast enough.

However, you may be wondering about its cost, which internet providers offer it, and how it differs from other speeds. Well, to answer these, I tested the Xfinity Blast service for 21 days, and have shared my findings below.

Downloading Experience

You can take up to 17 gaming sessions and download a file of 170 GB in just 1 hour. Also, the 400 Mbps of internet allows music lovers to stream up to 666 Spotify sessions. Even you can take Zoom HD video calls without any lag.

Anything above 25 Mbps is considered good for streaming videos, gaming, uploading, and downloading large files. The duration, however, depends upon the plan you are using. So, 400 megabits per second can allow you almost all data-intensive tasks.

Is 400 Mbps Good for Working From Home?

Encountering lag or slow network issues when video calls can be super annoying, but is it the same case with 400 Mbps?

Absolutely not!

This internet plan can make your Zoom, WhatsApp, or Skype calling experience pleasant. Zoom video calls have a bandwidth of 3.8 Mbps for HD calls. So, with 400 Mbps WiFi, you can make up to 10 HD Zoom calls simultaneously. In the case of 720p HD calls, an entire office can do the calling at the same time.

Coming to WhatsApp calls, almost 150 devices can remain connected at the same time. Similarly, Skype calls allow up to 300 connected devices with this plan.

How is 400 Mbps for Streaming and Gaming?

Netflix HD videos have a bandwidth of 25 Mbps per stream in case of download speed. So, yes, 400 Mbps is good for streaming.

To be more specific, you can stream Ultra HD Netflix videos almost 16 times. YouTube videos have even less bandwidth, a maximum of 5 Mbps, which means you can watch as many as 80 such videos.

Audio streaming platforms like Spotify or Apple Music require only up to 1 Mbps. So, with this plan, almost 666 Spotify streams can be enjoyed at the same time. A huge number indeed for the concerned speed plan.

In the case of gaming, you need to consider both upload and download speed for a smooth and lag-free gaming experience. A bandwidth of up to 3 Mbps is said to be ideal enough for gaming.

With the 400 Mbps, you can simultaneously have almost 60-70 online gaming sessions.

Note that you must have a good gaming modem and a capable dual-band or tri-band routing unit to experience low-ping gaming.

Another thing is downloading games. High-end games like Quantum Break, having a 178 GB file size, can be downloaded in just 1 hour with an internet speed of 400 Mbps. Also, low-end games like Minecraft and puzzle games will take you just 4-5 seconds.

The Cost of 400 Mbps Internet
