Why Roku Keeps Buffering Even With Excellent Connection – Tips And Tricks


If you’re an avid Roku user, you may have experienced the frustrating issue of buffering during a movie or TV show. Even with an excellent internet connection, this problem can persist. In this article, we will explore the reasons behind why Roku keeps buffering and provide tips and tricks to resolve the issue.

What Causes Roku to Buffer?

There can be several reasons why your Roku keeps buffering, including:

1. Slow Internet Speed

One of the most common reasons for buffering is a slow internet connection. While Roku requires a minimum internet speed of 3 Mbps for standard definition streaming and 9 Mbps for high definition streaming, it’s recommended that you have at least 25 Mbps for smooth streaming.

2. Network Congestion

Network congestion can also cause buffering, particularly during peak hours. This occurs when too many devices are connected to the same network, using up the bandwidth.

3. Router Placement

The placement of your router can also affect buffering. If it’s too far away from your Roku device or obstructed by walls or other objects, the signal strength may weaken, resulting in buffering.

4. Outdated Software

If your Roku software is outdated, it may not be able to handle the latest streaming technology, resulting in buffering.

How to Fix Buffering on Roku

Now that we’ve identified the causes of buffering, let’s explore some ways to fix it.

1. Check Your Internet Speed

Start by checking your internet speed using an online speed test. If it’s less than the recommended speed, contact your internet service provider to upgrade your plan.

2. Reduce Network Congestion

To reduce network congestion, limit the number of devices connected to your network, particularly during peak hours. You can also prioritize your Roku device for bandwidth allocation in your router settings.

3. Improve Router Placement

Place your router in a central location, away from walls and other obstructions. You can also consider a Wi-Fi range extender or a mesh network to improve signal strength.

4. Update Roku Software

Ensure that your Roku software is up-to-date by going to Settings > System > System Update. If an update is available, download and install it.

Additional Tips to Prevent Buffering

In addition to the above fixes, here are some additional tips to prevent buffering on Roku:

1. Clear Cache

Clear your Roku’s cache by going to Settings > System > Advanced system settings > Storage > Clear cache. This helps to free up memory and prevent buffering.

2. Use Wired Connection

If possible, use a wired connection instead of Wi-Fi to prevent signal interference and improve speed.

3. Close Other Apps

Close any other apps running in the background to free up memory and improve streaming performance.

4. Upgrade Your Roku Device

If your Roku device is outdated, consider upgrading to a newer model that can handle the latest streaming technology.


Buffering on Roku can be frustrating, but it’s not inevitable. By following the tips and tricks outlined in this article, you can enjoy uninterrupted streaming on your Roku device. Remember to regularly check your internet speed, reduce network congestion, improve router placement, update software, and use additional tips to prevent buffering. Happy streaming!
