To check the quality of the Internet connection, you may use the ping command.
Run the Command Prompt:
To do this in Windows OS, press Win + R.
In the window that appears, type cmd and click OK.
At the command prompt, type ping 188.8.131.52 and press Enter.
In the obtained results we are interested in the time parameter. The smaller it is, the better.
The maximum value, preferably, should not be above 150 ms.
Run the command ping 184.108.40.206 -t and press Enter.
The result will be displayed on the screen until you click Ctrl + C.
There should be no lost packets in the result.
Lost packets (Request timed out) indicate a problem with connecting to the resource that you ping.
Lost packets and high response time (above 150) can cause unstable broadcast, freezes, and pixels.
