About this tag
NCSI, or Network Connectivity Status Indicator, is the Windows component that reports whether your PC has internet access. When NCSI malfunctions, Windows may show a "No Internet" warning even though web pages load normally. This tag covers troubleshooting steps for NCSI issues, including disabling IPv6, editing registry probe values, and running SFC/DISM to repair system files. It also explores which Windows services, such as DirectAccess, rely on NCSI for connectivity checks. Understanding NCSI helps resolve misleading network status icons and ensures accurate internet connectivity reporting.
