I want to monitor wlan area and I want to read all information such as RSSI about the connected devices to wlan. There are many applications which use ping to retrieve information but I want to retrieve them directly from the access point. I don't know how to connect to wlan router and retrieve the data and which language should I use. thank in advance for any kind of help.

What I have tried:

I want to build tool to monitor the wifi area in a building.So now I want access to my access point and retrieve all information about the devices like the signal strength and the noise rate and other information that will help me to analysis and manage the wireless network.
