From the developer: "This program will check an Internet or network connection by pinging a specified host. When the host replies, it will show a green light (or yellow to indicate lag). However when no reply was received in time or the IP address could not be found, it will show a red light. The program uses sounds to alert the user, and can be minimized to the system tray. New in version 2.0: spectrum graph showing response times; mulptiple profiles can be configured easily; real-time logging; separate logfile for each profile."
