Ping command

A simple way to see if your internet is active, and to be able to access certain websites is the Ping command. From the Start menu, type Command Prompt, in the Command Prompt window enter the Ping Google.com command or Ping Genk.vn.

If you see the display of feedback signals at the same time, that means your internet network is working normally and can access that website.

If you do not receive a response from a website, you cannot access the site. If this is the same for other websites, then your internet has experienced problems. If the latency is high, you can still go to that site, but the page loading speed will be very long.

There are some websites that never respond to the Ping command, such as the Ping command microsoft.com will not give feedback, although you can still access the site.
