These Roku buffering improvements are just a few of the things to try with Roku devices, from changes to some modem tips, and even Roku apps and operating systems.

The tips and improvements on this page apply to all Roku models, including the Roku Streaming Stick 4K, Roku Ultra, and Roku Express product lines.

Why Does the Roku Keep Buffering?

A slow Internet connection, overheating, or an outdated operating system can cause the Roku to buffer. Plus, some media apps that automatically switch to high-resolution video on slow connections that can’t handle large files can also cause buffering.

What should I do to stop buffering?

Here are all of the best ways to stop buffering when using a Roku to stream media.

  1. Restart your Roku: As always, a quick restart that only takes a few seconds can fix your buffering issue and other related issues.
  2. Reboot your Roku: Turning off your Roku frequently can fix most bugs and glitches.
  3. Update your Roku: Update your Roku’s operating system to the latest version. You can do this by selecting Settings > System > System update > Check now.
  4. Remove a channel or app and then re-add: You have to remove the app or channel which is causing a lot of buffering and then add it again.
  5. Check for overheating: If your Roku starts buffing after an hour or two of turning on, it may be overheating. Clean it frequently so it doesn’t collect dust, and make sure it’s on a hard surface rather than a cloth or cover. You may also want to place it on its side so that more of its surface is exposed to the air.
  6. Switch to a wired internet connection: If possible, connect your Roku device to a wired Internet connection. Wired connections can be faster than wireless connections and reduce the likelihood of media buffering.
  7. Disconnect other devices from your internet: Smartphones, tablets, computers, and video game consoles can all cause buffering when trying to stream media while using the Internet. The network becomes overwhelmed and cannot process all downloads and uploads at once. Try putting these other devices in airplane mode or canceling any downloads or updates they are playing.
  8. Restart your modem: A quick modem reset will create a new connection to your Internet service provider, which can often be faster than your first one.

If you have a 5G modem, turn it off for at least five minutes so that the connection is completely reset. Some models may require 10 minutes to completely disconnect from the initial connection.

  1. Use your Roku at a different time: Internet services often get a lot of traffic on Friday and Saturday nights which can slow down speeds for everyone. Experiment with streaming content on your Roku at different times on different days to see if you can get less traffic and faster speeds.
  2. Switch to a faster internet connection: Slow internet connection is a common cause of Roku buffering problems. If possible, see if you can connect to another one with faster speeds and less traffic.
  3. Talk to your internet provider: Your service provider can analyze your Internet usage to find possible reasons for slow download speeds. They may be able to suggest manual changes to your router settings or even offer to upgrade you to a faster Internet service.
  4. Manually change the video quality: Many Roku apps, such as YouTube, allow you to change the resolution of videos in their media players or app settings. Try selecting 1080p instead of 4K to see if it prevents buffering. If buffering persists, select a quality or resolution setting of 720p or lower.
  5. Clear the Roku’s cache: On your Roku remote, press Home five times, up once, twice, and fast forward twice to clear the Roku’s cache. It may take from several minutes to half an hour to complete.
  6. Reset your Roku: If nothing else works, you can try resetting your Roku to its factory settings. Doing so will delete all your preferences and get them back as you found them when you first set up the Roku.
  7. Upgrade to a newer Roku: If none of the above fixes stop buffering, the problem may be that your Roku is too old.
  8. Use another device: If your Roku doesn’t turn off buffering and buying a new model isn’t an option, try streaming content from apps on other devices. Smart TVs, video game consoles and some Blu-ray players support many popular streaming apps. You may also be able to cast content from your smartphone, tablet or computer to your TV.

How Do I Fix Frequent Buffering?

Frequent buffering is almost always caused by a slow internet connection or a hardware-related issue.
