Speed ​​of downloading YouTube videos is as slow as slugs, this is a fix

YouTube is one of the largest and most popular online video hosting and sharing websites. However, while watching videos on YouTube, many users complained about the "slow slug" video loading speed of this site.

In the article below, Network Administrator will guide you and show you some ways to overcome this situation when watching videos on YouTube.

1. The cause may be due to a slow Internet connection

If your Internet connection is slow, it may cause some problems. Then try:

1. Switch to using 5 GHz band (if your router supports it).

2. Perform a speed test: If your network speed is less than 5 Mbps, then you must find and connect to another network to stream YouTube videos.

Refer to this article to learn how to correctly check the speed of Internet connection!

3. Alternatively, apply a 20% faster Internet acceleration procedure on your Windows computer.

This trick sounds quite old, but this is one of the best ways to improve Internet speed directly on your Windows computer. When Internet speed has improved, the speed of loading videos on YouTube will also be improved.

On Windows versions, Microsoft always reserves 20% of the system's total bandwidth to use for other purposes such as Windows Update and controlling users' computers. However, users can completely remove this mode and use the entire bandwidth to speed up internet connection.

Refer to the steps to speed up internet 20% faster in Windows here.

2. Other causes

If your Internet connection speed is stable, you can connect to other websites fast, but opening YouTube videos is quite slow, then:

1. Check to see if the YouTube connection problem fixes the problem.

2. Switch to using a video player with HTML5.

This mode uses the latest HTML5 technology for video presentation. It means that instead of using Flash Player that is too old, YouTube will use HTML5 instead.

In theory, there will be no difference, but actually using HTML5 will help videos load faster than using Flash Player. But there is one limitation: not all videos support HTML5. You can access this mode here .
