It’s so simple, open a Command Prompt from “Search” or “Cortana”. Type Command Prompt or CMD then click Command Prompt.

In the Command Prompt type ping google.com -t then press enter on your keyboard. The -t means it will continue to ping google.com until you stop it. To stop the ping press Ctrl + C on your keyboard or close the Command Prompt window.

The Request timed out means that the packet request sent by the ping command to google.com servers was not able to receive an answer in due time that’s why the packet request was discarded and therefor gave us a Request timed out response.

If there are too many users that are downloading at the same time you can also see Request timed out while ping is running. It will be gone as soon as the downloads are finished. You can see on your router on which users are using large bandwidth at the moment, use it to compliment ping in troubleshooting your internet.

If your modem or router is having a hard time in processing all the request you should see a higher value in time=1ms, if the value shoots up to 1000ms or higher than 1ms it’s an indication that it is busy or hanging-up. Hanging-up could be caused when the device is getting hotter than normal.
