When watching a movie or playing a video game, then the dreaded spinning circle appears. The annoying pause in your streaming/gaming experience. In this blog we will explain what can cause buffering and ways to stop it from happening.
What is buffering?
Buffering is when your device, like a TV pauses a video stream to load more data before it resumes playing. If your internet connection can’t download the media quick enough to keep up with the playback, your TV stops and waits until enough data has been downloaded to commence playing.
What are the common causes/fixes for buffering?
Below are the most common causes and possible fixes for buffering:
Slow internet connection: Streaming services require a minimum internet speed to deliver playback without buffering:
- Standard Definition: 3-4 Mbps
- High Definition: 5-8 Mbps
- 4K/Ultra HD: 15-25 Mbps
If you have multiple devices using the network at the same time, or you are on a slow internet speed plan, you may not have enough bandwidth (data transfer rate) to use the streaming service.

Wi-Fi issues
Even with the quickest internet speed plan, an unstable or weak Wi-Fi connection can cause buffering. Interference from electrical appliances, too many devices on the Wi-Fi network, thick walls or distance from the router can weaken your signal. Try moving closer to the router, using a Wi-Fi extender, or connect your device directly to the router with an Ethernet cable for better performance.
Network Congestion
If you are streaming during peak times like at weekends or in the evening, your internet service provider (ISP) may throttle your internet speed due to high consumer demand. Check with your ISP if they offer a higher priority plan when using the internet at peak times or limit other devices using the network when you are streaming.
Outdated app or streaming device
Buffering can occur if the app/software you are using is outdated, or your streaming device may not be able handle the newer high-resolution streams. Update your streaming apps/software. If your streaming device is several years old, consider upgrading to a newer model.
Video Quality
Streaming your TV programme or game at a high resolution requires more bandwidth (data transfer rate). Try adjusting the video setting to a lower resolution, such as from 1080p to 720p. This will reduce the amount of bandwidth required and improve stability.
Restart your router
Your router can slow down over time due to data build-up or long periods of use. Restarting your router will clear any temporary glitches and can improve performance.
Downloads or running background apps
If your device or another device in your home is downloading files or using apps which can consume a lot of bandwidth (data transfer rate) at the same time you are streaming, this can cause buffering. If possible, stop or pause unnecessary downloads/apps.
The streaming service
Occasionally, the problem is on the streaming provider's end. If a programme or game has just been launched there could be millions of people trying to access it at the same time, which can overwhelm the servers. Try pausing the show or game for a few minutes to let more data buffer or check social media to see if other people are experiencing the same issue.
In Summary
Your viewing/gaming experience doesn’t have to be ruined by buffering. Understanding the root cause, whether it’s your internet speed, your device or the streaming service. Checking the common causes outlined in this blog can help you find the correct fix so you can enjoy smooth, uninterrupted streaming.
