In the black window, type the following command and press Enter: netsh int ip reset restart tcp ip stack
Use this procedure if you experience:
"My internet is broken." IT: "Did you restart your router?" Me: "Yes." IT (quietly): Run CMD as admin → netsh int ip reset → netsh winsock reset → reboot netsh int ip reset In modern Windows versions,
If your internet is acting up but the router seems fine, try restarting the TCP/IP stack.
In older operating systems (Windows XP and Server 2003), the TCP/IP stack was managed by a specific service that could be stopped and started independently. In modern Windows architectures (Vista+), the TCP/IP driver ( tcpip.sys ) is a kernel-mode driver. It cannot be stopped while the OS is running. Therefore, a "restart" of the stack requires a registry reset and a system reboot. In older operating systems (Windows XP and Server

Navigate to /Library/Preferences/SystemConfiguration/ in Finder and move files like preferences.plist and NetworkInterfaces.plist to the Trash, then restart your Mac. macOS will automatically rebuild these files with default, clean settings upon reboot.
