Plex Keeps Buffering - How to Fix?

It is frustrating to experience buffering during video playback. Recently many users complain that they encounter buffering on Plex. At first, they think it is temporary and it will improve after a while. But later on, they find Plex keeps buffering for a long period of time and does not seem to improve. This is the main topic today. How to fix Plex buffering issue? Aside, we may dig further to learn why buffering happens and what to do if Plex keeps buffering?

Part 1: Why is Plex Constantly Buffering?

First things first. Why Plex suffer buffering constantly while other media servers in the same category do not seem to have so much buffering? Problems with video buffering can be frustrating and have a negative impact on your live video streaming experience. Reasons for constant buffering may blame various causes. One of the most common causes is your network connectivity. If your network does not work fast enough, or your network is suddenly disabled, you will definitely not be able to stream any video playback online so buffering may blame the poor network.

Second, the Plex media server has different video quality categories. To ensure smooth playback on Plex, you may need to choose the correct streaming quality for your situation. That means if your streaming quality is set too high, you may easily get buffering during playback. Third, the streaming devices may also be the cause for constant buffering on Plex. If your streaming device is not working properly, how can Plex stream videos smoothly?

Last but not least, buffering on Plex may blame the transcoder throttle buffer. As you may know, the Plex media server has a default setting for buffer and many would adjust the default settings but that may lead to buffering. In a normal situation, it is a way to reset the transcoder throttle buffer to allow Plex to stream the data closer to real-time.

Part 2: How to Fix ‘Plex Keeps Buffering’

Aforementioned, we learn that Plex buffering may blame network connection, streaming quality setting on Plex media server, streaming device, and transcoder throttle buffer settings. The point is what to do if Plex keeps buffering? Hence how to fix Plex suffering has become a heated topic nowadays. We will share some insight on this topic.

To begin with, we can check our network connectivity. There are websites to test network speed such as SpeedTest. If your network does not work fast enough, it is very likely to experience buffering on the internet suffering. There are several ways to stop and prevent buffering on your network, such as upgrading your router, reducing background processes, and removing malware from your system.

Adjusting the streaming quality is a way to fix Plex buffering issue. If your streaming quality is set way beyond your system capability, Plex will surely experience buffering all the time no matter how fast your network is. The correct thing to do is lower the stream quality to one that can be supported by your system, which will help to stop the buffering.


Making sure your streaming device works correctly is also a solution to stop Plex from buffering. We know if we are running on an age-old system, it might easily get us into the trap of buffering. An old system or device will surely need to be replaced or at least we need to ensure it can work properly if we want to eliminate the buffering.

Another solution to fix Plex buffering is adjusting the buffer setting on Plex media server. Test the transcoder throttle buffer and set the right one to make sure Plex stream the data closer to real-time.
