Want a Wi-Fi signal strength reading on your Windows laptop that’s more granular than those little bars? Here’s a batch file that will show the Received Strength Signal Indicator (RSSI) as a percentage. It updates the reading every two seconds. You can walk around the building or your home and see how the signal changes.
@echo off
cd\
cls
:HERE
echo.
netsh wlan show interfaces | find "Signal"
timeout /t 2
goto HERE
