Network Doctor

Network Doctor makes it easy to understand what’s happening with your internet connection. Run a simple network check and Network Doctor will examine the key parts of your connection, then explain the results in plain language. Network Doctor checks: • Network connection and connection path • Local networking and addressing • DNS resolution • Internet access over HTTPS • Internet responsiveness • Connection reliability When the check is complete, Network Doctor gives you an overall diagnosis along with individual results and useful recommendations for what to try next. Easy-to-understand results See whether your connection looks healthy, whether DNS may be causing problems, whether internet access is failing, or whether the connection appears slow or unstable. Diagnostic history Save completed checks locally so you can compare results or revisit a previous network problem. Technical details when you want them View additional information about your network interface, local addresses, and individual diagnostic results. Share reports Generate and share a diagnostic report when you need to send network information to a friend, technician, or support provider. Built with privacy in mind Network Doctor does not require an account. Diagnostic history is stored locally on your device and can be cleared at any time. Network Doctor is designed as a troubleshooting tool and does not measure internet bandwidth, Wi-Fi signal strength, router health, or ISP performance.
