    {
        try
        {
            string hosname = System.Net.Dns.GetHostName();
            IPHostEntry ent = Dns.GetHostEntry(hosname);
            string ip = ent.AddressList[0].ToString();
            bool ret = (ip != "127.0.0.1" && ip != "::1");
            //MessageBox.Show(ret.ToString());
            if (ret)
            {
                // MessageBox.Show("internet connected");

You have to ping google for example if a reply that means you have internet. What you've written is just checking if the device has ip address.
