Who Is On My Wifi is a simplified network scanner that shows you all the computers that are connected to your wireless (or wired) network. The program provides you with a lists of all the computers currently connected to your network, along with their computer name, IP address, Mac address and allows you to classify them as either Known or Unknown. Whenever an unknown computer connects to your network, the program will notify you via pop-up alert, sound or email message.Unfortunately, the program does not provide an option to limit monitoring to the wireless network adapter, therefore all your network devices are listed, wireless or not.
