Network Doctor: WiFi Check

Speed looks normal, but calls still lag? Check loaded latency, DNS, and the services you rely on—then keep and share the complete evidence.

Network Doctor helps you find why Wi-Fi or cellular connections feel slow—even when a basic speed test looks normal.

Run Quick Check or Full Check for: • Download and upload speed • Idle and loaded latency • DNS response time • Reachability of websites and services you rely on • Complete evidence, likely explanations, and practical next steps

Full Check is included in the app. Save any number of custom HTTPS targets, keep your complete local history, add notes, share the full report, and export CSV evidence when you need help from your ISP or IT team.

Results separate measured evidence from likely explanations and practical next steps. Compare latency under load, keep reports for recurring issues, and share evidence without creating an account.

Privacy: • No account required • No ads or third-party analytics • Reports stay on your device until you share them • Delete saved reports at any time
