ClearWiFi - WiFi Analyzer

ClearWiFi is a free WiFi analyzer and speed test that tells you why your WiFi is slow - in plain language, not just numbers. Walk around your home with Coverage Walk and see exactly where the signal dies.

Run the WiFi Doctor: it checks signal strength, channel congestion, DNS speed, ping and packet loss, security, and more - then explains what's wrong and exactly what to do about it. Tap a finding to jump straight to the fix. The first finding is free; unlock the full diagnosis.
