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.

    Windows 11 now has an internet speed test in the taskbar's network menu. To be clear about what it is: Windows does not run the test itself. The menu item opens a speed-test web page in your browser. It is a faster way to check a connection than searching for a test site, as long as you know...

    Why Full Wi-Fi Bars Can Still Mean a Bad Connection

    Full Wi-Fi bars on a Windows PC are reassuring, but they do not certify that the connection is fast, stable, or reliably delivering packets. The icon maps Wi-Fi link or signal quality; it is not a measurement of the entire route from the PC, through the router, and out to the internet. That...
