About this tag
Network troubleshooting on Windows covers a range of issues from DNS cache errors and Ethernet connectivity problems to Wi-Fi connection difficulties and SMB version checks. Common topics include flushing DNS to resolve server errors, verifying network settings when a connection shows as active but fails, and using built-in tools like the taskbar speed test or Microsoft Defender Firewall logging to diagnose blocked traffic. Users also troubleshoot router stability and file share access by checking SMB versions. These discussions focus on practical steps for home and small office networks, often leveraging Windows 11 features to reduce reliance on third-party utilities.
