Quick Start
- Click Check WiFi Strength.
- Wait for the test to complete.
- Review your estimated signal quality and dBm.
What the Results Mean
- -30 to -50 dBm — Excellent signal.
- -51 to -60 dBm — Good signal.
- -61 to -70 dBm — Fair signal.
- -71+ dBm — Poor signal.
Troubleshooting
- Move closer to your router.
- Avoid walls, floors, and metal objects.
- Restart your router if signal is unstable.
- Switch to 5GHz for speed or 2.4GHz for range.
Tips & Notes
- Browser‑based WiFi tests are estimates — real dBm requires hardware access.
- Run the test multiple times for accuracy.
- WiFi performance varies by device and antenna quality.

Why does my signal vary?
Interference, walls, distance, and router load affect WiFi strength.
Does this work on phones?
Yes — mobile browsers support this test.
