What is Bufferbloat? Causes, Testing, and Fixes

Listen to this post

In this article, we'll discuss the conclusion of bufferbloat- what it is, how to test for it, and how to fix it. Bufferbloat is a term used to describe latency spikes in broadband networks that are caused by excessive buffering.

One of the primary causes of bufferbloat is excessive buffering in routers and other networking devices. This can be caused by a number of factors, including inadequate memory or processing power, incorrect settings, or simply too much traffic for the device to handle.

Another common cause of bufferbloat is latency introduced by queuing. When packets arrive at a router faster than they can be processed, they are placed into a queue. The longer the queue, the more latency is introduced. This can be exacerbated by insufficient bandwidth or overloaded routers.

What is Bufferbloat?

Bufferbloat is a particular lag that occurs when your home Network is suffering from too much traffic.

Why is Bufferbloat important?

Gameplay will be extremely choppy once packats are lost.
Speed does not matter as much, the quality of the connection is crucial.
Movies can be buffered ahead of time, the computer can sort and compensate for lost packets.
Not desirable for online gaming, alla data need to be correct and sorted in real time

How To Diagnose Bufferbloat?

To test for bufferbloat, you can use the BufferBloat Test tool or the DSLReports Speedtest.

To fix bufferbloat, you can use the CeroWrt firmware or the Bottleneck Bandwidth Estimator.


Bufferbloat is a problem with the internet that results in a lot of data being sent over the network unnecessarily. This can slow down your internet connection and cost you money.

There are ways to reduce bufferbloat, but it takes effort and some knowledge about how the internet works. We hope you enjoyed this primer on how to get started with reducing you lag!
