You may encounter the error “One or more network protocols are missing on this computer” if you have tried to connect to the Internet or even if you were online and suddenly none of the pages open.

You’ve probably already run Windows’ built-in network troubleshooter and this error has occurred. Finding the cause of this error and fixing it can be very tedious, especially if you are not connected to the Internet.

Below are several ways to solve this problem.

What causes the “One or more network protocols are missing” error?

This error occurs when you run a Windows network diagnostic. It appears when your system fails to connect to the Internet and you click the “Diagnostic” button. This error may be caused by your Internet Service Provider. However, if other devices on the same network are working fine (and connecting to the Internet), then your computer is probably the problem.

Network protocols must be validated and installed by both the sender and receiver to ensure network or data interoperability. Networks use many protocols, often implemented at different levels. Without network protocols, you would not be able to send instant messages to your friends, emails would not reach their destination, and Web sites would not show up on your screen.
