When your computer's Internet connection is bogged down due to heavy traffic on your network, it can cause your "ping" to get excessively high. A ping is the amount of time it takes for a data packet to make a round trip from your computer to a remote computer. It is one measure used to tell how fast your Internet connection is. While you normally want a low ping, you can artificially inflate your ping by inducing an abnormally large traffic pattern on your computer.
Click the Windows "Start" button. Type "cmd" into the search field at the bottom of the Start menu, then press Enter to open a Command Prompt window.

Type "ping 127.0.0.1 -t" into the Command Prompt.
Press Enter and your computer will start pinging itself, creating more traffic that will help to cause a higher ping on your connection. When you are finished, you can close the Command Prompt window to stop your computer from pinging itself.
