In Windows, you can use different ways to measure and determine WiFi signal strength. If you are ever in doubt, follow the below steps to see the signal strength in numbers.
Windows makes it quite a lot easier to connect to any WiFi network you want as long as it is open or you have the password. When you connect to a WiFi network the signal strength will determine the connection quality and even the speed of your internet connection. If the WiFi signal is poor, the connection will be unreliable with frequent disconnects and unresponsive internet.
There is any number of reasons why your WiFi signal strength is low or poor. One of the most common reasons is that your system is too far away from the WiFi access point or there are too many obstacles, like thick walls and concrete between you and the WiFi access point.
See WiFi Signal Strength in Numbers
Typically, Windows shows the signal bar to check the WiFi signal strength in numbers. You can see that both on the taskbar and in the network connections flyout menu. Additional, the same signal strength bar will also appear in the Network Connections page. This is good if you want an approximation.
However, if you want solid numbers like percentage, you need to dig a bit deeper. It's pretty easy to do. Follow the steps shown below as is and you will be good.
Since Windows doesn't show the signal strength in number in the UI, we are going to use the good old Command Prompt or PowerShell.
1. First, open the start menu, search for Command Prompt and click on the first result to open the Command Prompt window.
2. In the Command Prompt window, execute the below command.
netsh wlan show interfaces
3. As soon as you execute the command, the Command Prompt will show your WiFi connection information. In that, you can see WiFi strength in number right next to "Signal".
Windows will show the signal strength in the percentage. The higher the percentage (up to 100%), the better the signal strength is. In my see, the WiFi signal strength is 100%. If your WiFi access point is further away from you or if there is a thick wall(s) between your system and the WiFi access point then you will see a lower number suggesting the low signal strength.
You can also execute the same command in PowerShell to get the exact same response.
As you can see, the process is pretty simple and a single line of command away. When your WiFi signal strength is low, you can improve it either by moving your WiFi access point closer or you moving closer to the WiFi access point or buying a good WiFi repeater to extend the signal. I recommend you buy a WiFi repeater or extender since they are cheaper and get the job done much more efficiently. Most of all, you don't have to move things around just for a good signal.
