When a video buffer while streaming, that means that your device is not able to get enough data from the server to keep it playing. It could be due to a slow or unstable internet connection, network congestion, weak Wi-Fi signal, device performance, browser issues or a high volume of streaming on the platform. In some situations, the video resolution is just too good for the link. The first step in buffering is to understand the cause. Changing the video quality, restarting the router, shutting down unnecessary programs, and making improvements to the WiFi signal can help in most cases.
What Causes Video Streaming To Buffer?
Streaming services continuously download a little bit of data about the video that you are watching. The process is known as buffering. A small buffer helps to smooth playback, but if consumption of the data stored in the buffer is outpaced by the downloading of new data, playback will pause.
There are a variety of causes that can cause this issue. Your internet speed is one of the most typical, but not the only things.
Common causes include:
- Slow internet speeds
- Unstable Wi-Fi connections
- The network appears to be overloaded with devices.
- Heavy usage of the network during peak periods.The load on the network during peak times.
- Using a high video quality setting.Using high video quality settings.
- Using an old browser or streaming applications.
- Device performance problems
- Virtual Private Networks (VPN’s) or proxy connections.
- Issues with the streaming service itself.
What matters is that buffing doesn’t necessarily indicate that your internet connection is slow. High advertised speed does not always mean that the connection will be uninterrupted as it may be affected by Wi-Fi interference, congestion or temporary network issues.
How Internet Speed Affects Streaming
To stream a video, the data must flow. The larger the video resolution, the more bandwidth it will use due to the amount of data contained in the video.
For instance, standard-definition video typically consumes a lot less bandwidth than that used for HD or 4K streaming. Bandwidth may be shared among several people watching videos, playing internet games, downloading files and/or using cloud services concurrently.
You can also have varying speeds throughout the day depending on the actual speed of your connection. In cases where many users are online at the same time, Internet providers can have network congestion.
To be sure if your connection is performing as expected, you can use a speed test. Perform the test when there are no large downloads occurring, and compare the result with the requirements of the streaming service used.
Wi-Fi Problems That Can Cause Buffering
Video buffering can occur even if you have a high-speed Internet connection, but your Wi-Fi is not working properly. It can be that your gadget is too far from the router, or walls and other electronic devices could interfere with the wireless signal.
The quality of the Wi-Fi connection can also suffer in cases where there are a lot of devices connected to one router. Devices such as phones, laptops, smart TVs, games and smart home devices all vie for network resources.
Try these fixes:
- Approach the router closer.
- Turn on your router and modem.
- Unplug equipment that isn’t being used.
- When possible, use 5 GHz or 6 GHz Wi-Fi network.
- Do not place the router in an enclosed area.
- Where possible use an Ethernet cable for smart TVs.
If streaming is fine via Ethernet but slows down when using Wi-Fi, then Wi-Fi may be a contributing factor.
Device, Browser, And App Issues
Not all the time, it’s not the network! Video may be struggling to be processed by your streaming device.
High-resolution video can be a challenge on older devices, such as phones, computers, smart TVs and streaming devices. Multiple applications (or browser tabs) running simultaneously can also consume memory and processing power.
Close all of the apps and browser tabs that you don’t need. Re-connect the device and attempt to stream again.
Keep an eye out for updates, too. Platforms like streaming services continually update their applications and websites to ensure compatibility, security and performance.
Clear the browser’s cache and keep the browser up to date when viewing videos using a web browser. You may need to try another browser to check if the issue persists.
Restarting the device will resolve temporary issues that can affect playability on smart TVs and streaming boxes.
Streaming Service And Network Congestion
Sometimes your home network can be functioning properly, but buffering still occurs. Streaming platforms have extensive networks to serve video to millions of users, but there can be occasional technical issues.
Traffic may be high, service outages may occur, or service disruptions may impact a region. You may also have congestion and/or routing problems with your internet service provider that impact access to a specific service.
There are many ways to determine where the source came from, but one easy method is to test a number of services.
For instance, if one stream buffers and the other services and sites function correctly, the issue might be limited to that service and/or that connection.
You can also see if there are issues reported by other users of the same service. If you’re experiencing an outage across the entire network, you might not be able to correct the problem by changing your settings on your device.
Quick Fixes For Video Buffering
Experiments with the basic solutions first, then the advanced ones. Most buffering issues are short-lived and can be fixed in a couple minutes.
- Restart your router. Unplug it, wait for a while and then reconnect it.
- Restart your device. This can resolve temporary software and memory problems.
- Reduce video resolution. Tune to switching resolution from 4K to HD or from HD to lower.
- Pause other downloads. Bandwidth can be used up by large downloads and uploads.
- Close unnecessary apps. Other applications can have network or system needs.
- Boost Wi-Fi connection. Get closer to the router or connect to it via the wired connection.
- Turn off the VPN for the time being. Some VPNs can slow down the streaming service.
- Update the app and/or browser. Newer versions may fix playback problems.
- Test another service. This will help identify if the problem is platform specific.
- Do an internet speed test. Make a comparison between what you actually receive and the connection you normally receive.
Continue buffering if these steps fail: Check if the problem is happening on one device or on the whole network. If you all have some problem, it is probably a problem with your internet connection or your provider.
How To Prevent Streaming Buffering
Buffering is easier to avoid, when your network and devices are well-maintained. Make sure you place your router in an open area where there’s no strong interference sources. Always have the latest versions of streaming services, operating systems and browsers.
If multiple users regularly use your connection at the same time, you should check if your internet plan has sufficient bandwidth for your family. If bandwidth really is a problem, a faster plan may be of help, but it won’t cure poor Wi-Fi or device performance.
Wherever possible, wired Ethernet is better for demanding applications like 4K streaming than Wi-Fi. Also get rid of unnecessary downloads while watching high-resolution video playback.
This will depend on the cause and can vary from the best. If it’s the same streaming device that is old or a feeble wireless sign, there’s little benefit to upgrading the internet plan.
Final Thoughts
There are many reasons why video buffers could be frustrating, but usually, it is easy to understand the reason. The basic steps are: Test your internet speed, restart your router and device, lower video resolution and boost WiFi signal.
If only one streaming service is affected, see if that service is having technical difficulties. If all devices are buffering, check your network or internet connection.
You can usually pinpoint the reason for your video buffering by testing each possible step in turn, thus avoiding unnecessary changes and finding a practical solution.
