I want a software that would tell me what other devices are connected to the Wireless Network I am connected to. Maybe it could offer some more info about them. Better if free.
Scanning a network that does not belong to you is illegal. That said, how do you want to scan. If your know your IP and how to get it, I would recommend Colasoft Mac Scanner. http://www.colasoft.com/mac_scanner/index.php?act=mac_scanner
