I need an application that can tell me the signal strength of my wifi connection in real time that uses the wifi adapter. Kind of like back in the day when people used to move the television antenna around until the picture was clear, I was looking for something with the same type of thing that has a percentage based scoring system like 1-100% and it changes as I move the Wifi adapter, because I am trying to find the best position for my adapter to pick up my router that is about 15-20 yards away inside my work shed.
If you have a android phone you can use Wifi analyzer it can measure dBm.
Good Luck.
