Network Test — Check Connection Type & Speed

Check your network connection details using standard browser APIs. This test reads your connection status, effective connection type (4g, 3g, etc.), estimated downlink speed, round-trip time, and whether Save-Data mode is enabled.

Network Diagnostics

Inspect your live connection using standard browser APIs. Online/offline and connection metrics are read directly — nothing is estimated.

Before you start

  • Online/offline detection works in every modern browser.
  • Detailed connection metrics depend on the Network Information API.
  • Reported speeds and RTT are browser estimates, not measured throughput.
  • The "4g" label is the highest effective type — it does not confirm 4G/5G radio.

Reported speeds and RTT are browser estimates, not measured throughput. We never fabricate them.
