Hello,

first of all, please excuse me for my english.

I used the following code to connect to pre-configured Wi-Fi network by it's ssid _ON WINDOWS MOBILE_.

void connectWireless(string ssid)
  {
   NetworkInterface[] interfaces = (NetworkInterface[])NetworkInterface.GetAllNetworkInterfaces();
   WirelessZeroConfigNetworkInterface wzcInterface = null;
   foreach (NetworkInterface ni in interfaces)
   {
    if (!(ni is WirelessZeroConfigNetworkInterface)) continue;
    wzcInterface = ni as WirelessZeroConfigNetworkInterface;

    try
    {
     for (int i = 0; i < wzcInterface.PreferredAccessPoints.Count; i++)
     {
      string apName = wzcInterface.PreferredAccessPoints[i].Name;
      if (apName.Equals(ssid))
      {
           if (!wzcInterface.AssociatedAccessPoint.Equals(apName))
       {        bool b = wzcInterface.ConnectToPreferredNetwork(apName);         }
      }

     }
    }
    catch (Exception ee)
    {
     MessageBox.Show(ee.Message);
     return ;
    }

     }
   return ;
  }

Now I'm trying to use code on Windows CE 5.0 (Doplhin 7600 handheld computer), and problem is that in

  foreach (NetworkInterface ni in interfaces)
   {
    if (!(ni is WirelessZeroConfigNetworkInterface)) continue;
    wzcInterface = ni as WirelessZeroConfigNetworkInterface;...

wi-fi interface returned is not of type WirelessZeroConfigNetworkInterface, but of type WirelessNetworkInterface.

It doesn't have PreferredAccessPoint properties and ConnectToPreferredNetwork method. So I use

foreach (NetworkInterface ni in interfaces) {
if (!(ni is WirelessNetworkInterface)) continue;
wzcInterface = ni as WirelessNetworkInterface;

try {
if (!wzcInterface.AssociatedAccessPoint.Equals(ssid))
{
wzcInterface.Connect(ssid);
bool b = true;
}
......

And looks like it doesn't work.

Does anybody has an explanation except DNA error?

Thanks in advance,

Gleb.
