Here's an easy way to do it by calling the API function InternetGetConnectedState: using System; using System.Runtime.InteropServices; class Test { [DllImport(wininet.dll)] extern static bool InternetGetConnectedState(out uint lpdwFlags uint dwReserved); static void Main() { uint flags; bool isConnected = InternetGetConnectedState(out flags 0); if (isConnected) Console.WriteLine(This machine is currently connected to the internet); else Console.WriteLine(This machine is not currently connected to the internet); Console.ReadKey(); } } If you need it it's also possible to tell what sort of connection you have by examining the 'flags' variable after the call.
