If you think you are connected to your ISP but you still can’t communicate, you can use some of the command-line tools provided with Windows to trace TCP/IP problems. (TCP/IP is the network language or protocol used by the Internet.)
To run the command-line utilities, first open a Command Prompt window by right-clicking the very bottom-left corner of the screen and selecting Command Prompt. Then, type in the commands as we describe them later. If you’re not familiar with a particular command-line utility, type the command name followed by /?, as in this example:
ping /?
