Monitoring Access Point Usage

First….I’m new here so let me apologize before hand if I didn’t search correctly and this has been covered before. Neat Forum though!

I am looking for a piece of software that will monitor our APs from the stand point of who is connected. I can find lots of programs that monitor alot of aspects but what I am looking for I can’t seem to locate. Simply put, I want to know any of the following: number of people connected, user names, mac addresses, etc. Anything that tells me who and/or how many are using our APs.

Thanks in advance.
