MiniPing

MiniPing is the minimal keep-connection-alive tool for your Microsoft Windows system tray area; the area next to the clock in the taskbar. To keep your internet connection active, MiniPing will try to fetch the first 16 bits of an online resource with a 60 second interval. This practically means that MiniPing will use less than 1 KB of your bandwidth per hour, which should be more than acceptable.
