WiFi Doctor: Fix Slow Internet

Is your WiFi slow, dropping or lagging? WiFi Doctor is a WiFi analyzer and internet speed test in one app. It finds out why your internet is slow in about 30 seconds and tells you how to fix it, in plain language.

Fix WiFi connection problems, check your WiFi signal strength, test ping and lag for games, and see if your internet provider gives you the speed you pay for. No technical knowledge needed.

⚡ INTERNET SPEED TEST
Measure your real download speed, upload speed and ping (latency). Run a WiFi speed test in any room and compare the result with the speed promised by your provider.

📶 WIFI ANALYZER & SIGNAL STRENGTH METER
See your WiFi network name, signal strength (dBm), frequency band (2.4 GHz / 5 GHz), channel and link speed in real time. Walk around your home to find where the WiFi signal is weak.

🩺 WIFI DIAGNOSIS IN ONE TAP
