In your home you may only have a WiFi network that you can connect to, that is, the one you pay or pay at home. In the unlikely scenario that your neighbor has an unprotected network, you could connect to it, but that is not ethical or legal. Instead, if you have the option to choose which network to connect to, you should definitely connect to the strongest one. Next I will show you how to measure WiFi signal strength in Windows 10.
Ways to measure the Wi-Fi signal
List of available networks
When you click on the WiFi icon in the system tray, you will see the list of nearby networks in a pop-up window. The WiFi icon next to each network will indicate the signal strength. The fuller the icon is, the stronger the signal. However, this is not very accurate and two networks may appear to have the same strength, even though they differ.
WiFi signal strength values
If you need a more accurate way of knowing which network is transmitting the strongest signal, download the WiFiInfoView app and run it.
This application will provide you with information about nearby networks. In this case we are interested in the intensity of the signal, so you can obtain it in the Signal Quality column . The higher the value of a network in that column, the stronger the signal that is transmitted from it.
You can also check the Average Signal Strength column . This allows you to verify if the network can consistently provide the power that it is transmitting at that moment. You should let the application run for a few minutes so that it can collect information more accurately.
All this information can be obtained regardless of whether you are connected to a network or whether it is password protected or not.
Symbol of the system
This method only works for the network you are connected to. Open Command Prompt and run the following command:
netsh wlan show interfaces
Go to the bottom of the window and you will see the Signal input that tells you how strong the signal is from the network you are connected to.
As with the Command Prompt, with PowerShell it only works for the network you are currently connected to.
Open PowerShell and run the following command:
(netsh wlan show interfaces) -Match '^ \ s + Signal' -Replace '^ \ s + Signal \ s +: \ s +', ''
The command will return the signal strength as a percentage.
