Common Causes Of Buffering And How To Prevent It

The internet has given us many things to view and interact with, such as TV shows, live streams, and games. However, with access to the internet, certain technical problems occur, such as buffering, which slows down the experience. It’s helpful to understand the common causes of buffering to know how to prevent it.

Common Causes of Buffering and How To Prevent It


The Source of Wi-Fi Is Stretched Thin

If you have numerous devices connected to the internet at once, this may cause the signal strength of each device to drop significantly. Routers will have a certain amount of signal strength they may supply to devices. But if multiple devices take too much of the signal, this may lead to buffering and longer loading times because the connection to the internet isn’t strong enough. Taking the time to power down devices and only connecting to the internet on your device will help reduce buffering.



There are times when signals are demanding and will waver due to the environment that surrounds the device. Interference is one of the most common causes of buffering, with most of it occurring because of other signals or the physical objects through which a signal travels. For instance, if you have thick concrete walls in a building, this may interfere with the strength and speed of a Wi-Fi signal. The walls can cause buffering in downloading or uploading data because of their density.

The different signals surrounding a device may also be a common source of interference, such as radio waves or electromagnetic signals. EM interference is a frequent issue in wired networks. It’s why manufacturers continue to find ways to improve network cables and reduce crosstalk in data communication. Crosstalk can cause weaker signals that lead to buffering and gaps in connectivity.

The best way to prevent interference, regardless of connection type, is to maintain a clear path for the signal to travel through. It’s best to keep routers and network cables isolated from other technology that may emit interfering signals.


Your Device Is Processing Too Much

Computer technology can perform various tasks at once, which greatly helps us in life. However, this multitasking ability comes with the downside of slower processing speeds, which are detrimental to actions like transferring information. If you have multiple tabs open on your computer or multiple downloads running in the background, the central processing unit (CPU) may become stretched thin. This is a common cause of buffering for tasks.

Keep actions that involve connecting to the internet to a minimum and only have tabs open that you intend to use within a few minutes. Your device will have less to focus on and will channel more of its processing ability into your current work.

Buffering is an annoying occurrence you should know how to prevent, and there are numerous causes for it. But by understanding why things are buffering and lagging, you’ll have a better chance of regaining a quality connection and getting back to the content you want to upload, download, or stream.
