Internet Speed Test

Signal quality is a composite score built from measured latency and throughput. Browsers do not expose raw Wi-Fi RSSI, so this proxy is the honest maximum we can compute without a native app.

Distance from access point is estimated from the log-distance path-loss model applied to the derived signal score. Treat it as a directional hint, not a survey.

How this compares. fast.com hides everything but download; fiber.google.com shows dual meters but no jitter or signal. LAFIA shows all five in one glance — analog and digital, mobile-first.
