How to check Wi-Fi signal strength on Windows using command prompt (cmd)

On Windows 10 / 11 there are a number of ways to check the wi-fi signal strength but I find the most accurate and simple way is using command prompt.

  1. Open up a command prompt by clicking start, type cmd then click “Command Prompt”.
  2. Enter the following command and press “Enter”.
    netsh wlan show interfaces
  3. Check out the “Signal” value to determine the quality of your connection.

If the number is equal or higher than 80%, then the strength of the signal is good. Anything below 60% is pretty poor.
