One of the components of the Internet connection on your computer is a built-in protocol called TCP/IP. TCP/IP can sometimes become corrupted. If your connection to the Internet is really slow or you cannot connect to the Internet and you have tried all other methods to resolve the problem, TCP/IP might be causing it. Because TCP/IP is a core component of Windows, you cannot remove it. However, you can reset TCP/IP to its original state.
In this article we are explaining how to reset TCP/IP Internet protocol in Windows 8. There are several ways to reset the TCP/IP Internet protocol. If you have any custom settings (default gateway, DNS server, etc.) you will need to manually set these again.
