What we check
The page reads navigator.onLine and, where a browser provides it, a general connection estimate.
Connection estimates are optional browser features and may be absent or imprecise.
What this test can’t tell you
It does not perform a speed test, measure latency, inspect Wi-Fi signal, or confirm that a particular service is available.
Something not working?
The estimate is unavailable
Many browsers do not expose connection information. The online/offline status can still appear.
It says online but a site fails
Online status does not prove that every destination is reachable. Compare another site or app.
Common questions
Is this a speed test?
No. It does not download a test file or report Mbps.
Why is the connection type missing?
Connection information is not supported consistently across browsers.
