Network Doctor
Network Doctor guides you through systematic network diagnostics without risky guesswork. It establishes baseline measurements first, isolates root causes across ISP, Wi-Fi, DNS, MTU, proxy, and background processes, then proposes only reversible fixes with before-and-after verification.
Network Doctor diagnoses slow internet and connectivity issues through safe, measurable troubleshooting steps.

What does Network Doctor do?
Network Doctor guides you through systematic network diagnostics without risky guesswork. It establishes baseline measurements first, isolates root causes across ISP, Wi-Fi, DNS, MTU, proxy, and background processes, then proposes only reversible fixes with before-and-after verification.
How can I diagnose network problems with Network Doctor?
Network Doctor starts by establishing baseline measurements to understand your normal performance. It then systematically isolates root causes across multiple layers—ISP connectivity, Wi-Fi signal quality, DNS resolution, MTU settings, proxy configuration, and background processes—pinpointing exactly where the issue originates.
Can Network Doctor check my network health?
Yes. Network Doctor monitors and assesses your overall network health status by measuring key performance indicators and comparing them against your baseline. This helps you understand whether your network is operating normally or experiencing degradation.
What kind of network issues can Network Doctor identify?
Network Doctor identifies root causes across ISP problems, Wi-Fi connectivity issues, DNS failures, MTU configuration errors, proxy misconfigurations, and background processes consuming bandwidth. It analyzes network performance metrics to pinpoint the exact source of your connectivity problems.
Are Network Doctor's fixes safe to apply?
Network Doctor proposes only reversible fixes, ensuring you can safely test solutions without permanent risk. Each fix includes before-and-after verification so you can confirm whether the change actually resolved your issue.
