WiFi Web Test Separates the Local Network from the Internet

Field notes

The local test uses paired browsers and a direct WebRTC path rather than routing the timed payload through the site’s server. The page specifies a bounded 1 MB seed file, bidirectional measurements, and metrics including latency, jitter, stability, and an experimental application-level loss estimate. For a more useful WiFi reading, it recommends testing a wireless phone or laptop against a computer connected to the router by Ethernet.
