Hello lois waisbrooker !Copy this code snippets and paste where which you want, This method return a bool type value and its parameter get a long value for minimumSpeed of your internet.public static bool IsNetworkAvailable(long minimumSpeed) { if (!NetworkInterface.GetIsNetworkAvailable()) return false; foreach (NetworkInterface ni in NetworkInterface.GetAllNetworkInterfaces()) { // discard because of standard reasons if ((ni.OperationalStatus != OperationalStatus.Up) || (ni.NetworkInterfaceType == NetworkInterfaceType.Loopback) || (ni.NetworkInterfaceType == NetworkInterfaceType.Tunnel)) continue; // this allow to filter modems, serial, etc. // I use 10000000 as a minimum speed for most cases if (ni.Speed &lt; minimumSpeed) continue; // discard virtual cards (virtual box, virtual pc, etc.) if ((ni.Description.IndexOf("virtual", StringComparison.OrdinalIgnoreCase) &gt;= 0) || (ni.Name.IndexOf("virtual", StringComparison.OrdinalIgnoreCase) &gt;= 0)) continue; // discard "Microsoft Loopback Adapter", it will not show as NetworkInterfaceType.Loopback but as Ethernet Card. if (ni.Description.Equals("Microsoft Loopback Adapter", StringComparison.OrdinalIgnoreCase)) continue; return true; } return false; }
