What the test will show

Monitor brief disconnections, latency spikes and unanswered requests. Save a chart and event log to share with your internet provider.

How to take the test

  1. Stop downloads and select a duration.
  2. Run the test and leave the tab visible.
  3. Compare the results using Wi-Fi and cable under similar conditions.

How to understand the result

A failed HTTP probe does not equal a lost IP packet. Time in a sleeping device is not considered an interruption.

Compare multiple runs under the same conditions. Then change one factor: connection, device, or setting. If the symptom persists, repeat the test on another device and save the conditions - this will help to more accurately describe the problem to support.
