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.
- Open up a command prompt by clicking start, type cmd then click “Command Prompt”.
- Enter the following command and press “Enter”.
netsh wlan show interfaces
- 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.
