WiFi DoctorWiFi analyzer & network tools for Android
Find the clues behind slow speeds, connection drops and websites that will not load. WiFi Doctor brings deep network diagnosis, speedtest, channel analysis and live monitoring together in one Android app.
Go beyond the signal bars
A Wi-Fi problem can start in your phone, the wireless link, your local network or the path to the internet. Follow nine connected stages to understand where the evidence points.
See how your connection really behaves
Measure download and upload throughput alongside ping, jitter and packet loss. Compare idle latency with latency during transfers to investigate lag, buffering and choppy calls.
Follow live device traffic, Wi-Fi signal and response times on readable charts. Watch for interruptions, mark important moments and review up to 30 minutes of chart history.
Give your wireless signal some room
Explore nearby networks on channel graphs, follow signal history and compare overlap. Channel ratings and recommendations help you make informed choices about placement, band and channel.
Look closer at both ends of a connection
Trace the connection through DNS, IPv4/IPv6, TCP, TLS and HTTP. Inspect redirects and certificates, compare DNS answers, and examine the route with traceroute where available.
Discover responding devices on your LAN and inspect available IP addresses, names, device types and advertised services. Make familiar computers, printers, TVs and smart devices easier to recognize.
Useful in the moments that matter
Use eight focused checks to review Wi-Fi, IP setup, network sign-in, DNS, Internet access and stability when you need a quick connection check.
Having trouble joining a network? Inspect the connection attempt and available system evidence to distinguish connection failures from later internet-access problems.
Revisit saved diagnoses and Speedtest results, inspect measurements and keep useful evidence for troubleshooting or a conversation with technical support.
Bring the evidence into the conversation
Give ChatGPT, Claude or another AI tool the diagnostic context behind your question. Export a report, review what you share, and ask about possible causes or useful next steps.
Sharing is your choice. Review the report before sending it. Analysis happens in the AI service you choose and follows that service’s terms and privacy policy.
A companion to every report
Explore all 83 checks, what they measure and how to interpret their values. Browse 132 sample results generated by the app’s diagnostic engine from synthetic inputs, with full JSON for deeper analysis.
Explore the diagnostic libraryWhat does RSSI mean? How should you read a dBm value? Go straight to the explanation for W30-010.
Read W30-010WiFi Doctor helps identify problems and opportunities to improve your connection. It provides measurements and guidance; actual improvements depend on the cause, router, device, and changes you make.
The catalog includes 83 checks. Some depend on hardware, permissions, available evidence, or an optional measurement. A check that cannot run is reported as unavailable or not applicable, rather than a confirmed fault.
Both are part of a wider Network Diagnosis workflow. WiFi Doctor combines Wi-Fi analysis and performance measurements with checks of device state, local connectivity, DNS, and internet access.
You can export diagnostic data and share it with ChatGPT, Claude, or another tool you choose. The external AI service interprets the report; WiFi Doctor provides the measurement evidence.
