What is jitter?

Jitter is the variation in the time between packets arriving, caused by network congestion, or route changes. The longer packets take to arrive usually affects audio. Jitter is measured in milliseconds (ms). If you are receiving jitter greater than 15-20ms, it can increase latency and result in packet loss.

Jitter, latency and packet loss can cause the following issues: choppy audio, delayed or dropped calls, static or garbled audio.


What can you do to resolve jitter issues?

  • Perform a Bandwidth test with a computer plugged directly into your modem. If you still have high jitter it’s most likely an issues with the Internet Service Provider (ISP). If you’re unable to test plugged directly into the modem, your ISP should be able to run the test for you. If they see any jitter issues on their end, they should be able to resolve them.
  • If the results are good plugged directly in the modem then it could be a couple of things
  • First check to see if you are experiencing any issues while the jitter is good. Jitter results can vary making it very difficult to diagnose. The jitter might have been high when the issue was occurring, and corrected itself by the time the test was run.
  • If everything is good on the ISP’s end then we could be looking at an internal network issue. Try running the test plugged directly in your router and work your way back until you find what network device is causing the jitter.
