At first, John thought it might be a problem with the conference software or the client's internet connection. But as the issues persisted, he realized that the problem might be with his own internet connection. He quickly grabbed his laptop and started searching for a way to test his internet jitter.
JIT-2026-04-14-001 Date of Test: April 14, 2026 Test Duration: [e.g., 10 minutes continuous] Test Tool(s): [e.g., PingPlotter Pro, iPerf3, WinMTR, Ookla] Target Endpoints: [e.g., 8.8.8.8, corporate VPN gateway, ISP gateway] test internet jitter
Testing internet jitter is the process of measuring the between data packets arriving at their destination. While speed tests show how much data you can move, a jitter test shows how stable that movement is, which is critical for real-time activities like video calls and gaming. What is Jitter? At first, John thought it might be a

John had heard of the term "jitter" before, but he wasn't entirely sure what it meant. In simple terms, jitter refers to the variation in delay between packets of data transmitted over the internet. In other words, it's a measure of how consistent or inconsistent the internet connection is.
When you send data over the internet, it is broken into small "packets." Ideally, these packets should arrive at regular intervals. Jitter occurs when there is an uneven delay between these packets, causing them to arrive out of order or in bursts. How to Test Jitter
: Older routers may struggle to process packets quickly during high-use periods.
