WiFi Health Check
Measure latency, jitter, and connection stability — what browsers can actually test about your wireless link.
What your browser can see
Web browsers cannot scan Wi‑Fi networks or read signal strength. This check measures latency, jitter, stability, and a short throughput burst — the same experience your apps feel on this connection.
Frequently Asked Questions
Can this page show my WiFi signal strength or network name?▾
No. Browsers block access to SSIDs, signal bars, RSSI, and noise levels for privacy. This tool measures latency, jitter, packet loss, and a short download burst — how your connection actually performs.
What is a good WiFi health score?▾
Scores above 85 are excellent — low latency and stable jitter, suitable for gaming and video calls. 70–84 is good for everyday use. Below 50 suggests noticeable lag, drops, or interference.
Why does it say cellular or ethernet instead of WiFi?▾
When available, your browser reports connection type via the Network Information API. On desktop Safari or some browsers the type may be unknown. Run the test on the device and network you want to evaluate.
How is this different from a speed test?▾
A speed test measures maximum download and upload over ~12 seconds. This health check focuses on stability — ping consistency, jitter, and spikes — which predict call quality and gaming lag even when raw Mbps looks fine.
How can I improve a poor WiFi score?▾
Move closer to the router, switch to 5 GHz, reduce interference, restart your router, or compare against ethernet. If speed is fine near the router but poor elsewhere, consider mesh WiFi or an access point.
