Do you know the exact spot which has the maximum Wi-Fi signal strength in your house? Well, you can probably tell that by the number of solid bars in the Wi-Fi icon in the taskbar. But that might not be the best way for you. The solid bars give you an abstract idea about how the signal strength but will not give you an exact number or value. The exact value can help you in your analysis and will also provide you results that can be used to improve Wi-Fi signal strength at your home or office.
Check Wi-Fi signal strength
1] Command Line Way
The simplest way of doing so will be by typing in some commands in a CMD window. This method does not require any software installation, it is simple and quick. Make sure you are connected to the Wi-Fi you want to run a signal test on. Now open a CMD window and execute the following command:
netsh wlan show interface
This will give you detailed information about the wireless network. This type of information is not available in network and sharing centre or even the settings app. You can view GUID, Physical Address, State, SSID, BSSID, Network Type, Radio Type, Authentication, Cipher, Channel, Receive/Transmit rate and most importantly the signal. The signal is represented as a percentage value and is the most accurate measure of the strength. You can run this command as many times and you will notice the change in signal values every time you move around your device a little bit.
