What causes frequent buffering on Roku?

What causes buffering

The main reason you experience frequent buffering on your Roku is due to a slow internet connection. If your network service provider is experiencing issues providing a solid connection, your Roku will not be able to load properly. 

For Roku to stream content without the need to buffer, it requires;

  • At least 1.5Mbps for standard content
  • 3.0Mbps for an HD display 

Reason 2. Roku device is overheating

If your device overheats, Roku will begin to buffer while you watch content.

This is because the internal hardware gets too hot, and cannot function properly. It won’t be able to store the necessary data required to play the movie straight through.

Reason 3. Outdated Roku software

Your Roku software will automatically get updated, however, if there was an error during an update phase, the upgrade will not install properly.

It’s important to make sure your Roku’s operating system is on its latest version to ensure the device operates at an optimal level.

Reason 4. Congestion

A high volume of traffic to the Roku server, or on your internet provider will slow down processing times.

This is when you launch Roku and stream during ‘peak hours’ or there has just been a new release, and subscribers are all accessing their Roku to watch it at the same time.

(Fun Fact: ‘Roku’ means 6 in Japanese, and represents the 6th company the founder of Roku, Anthony Wood, started up.)

How can I improve Roku streaming quality?

You can improve your Roku streaming quality by tweaking a few settings;

Change 1. Change image quality

If you are trying to stream on your Roku with the highest quality display image, this will slow down the time it takes to buffer because there is more data to be downloaded.

Changing the image quality to a lower resolution will decrease the display standard, but improve the streaming on your Roku.

Change 2. Move router closer

To improve the playback on your Roku moving your Wifi router closer to your device can help improve the connection, and make it stronger.

Doing so gets rid of any potential interferences that may be blocking the signal.

Change 3. Use an ethernet cable

Connecting your Wifi router to your Roku device with an ethernet cable will provide a stronger connection for your Roku to buffer the complete movie or episode before you play the video.

An ethernet cable eradicates any external factors that can interfere with a wireless signal, as the link stays between the two devices connected via the cable.


With your Roku no longer buffering repeatedly, you can get back to enjoying your all-time favourites, and switch between all the different online streaming services Roku has to offer.
