Network Doctor: WiFi Check

Speed test looks normal, but calls still lag? Check idle and loaded latency, DNS, and service reachability—then see measured evidence and practical next steps.

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

Run a guided check for: • Download and upload speed • Idle and loaded latency • DNS response time • Reachability of websites and services you rely on

Quick Check gives you a practical health check. Network Doctor Pro adds deeper Full Checks, more test targets, complete evidence, full local history, and report and CSV sharing through a one-time lifetime purchase.

Results separate measured evidence from likely explanations and practical next steps. Compare latency under load, keep reports for recurring issues, and share evidence with your ISP or IT team.
