C# WPF how to connect a wifi with password

Question

I use Managed Wifi API library and ok to connect a "HasProfile" wifi AP like this:

WlanClient client = new WlanClient();
foreach (var item in client.Interfaces)
{
    ViewModel.CurrentWlan = item;
    Wlan.WlanAvailableNetwork[] networks = item.GetAvailableNetworkList(0);
    foreach (Wlan.WlanAvailableNetwork network in networks)
    {
         var name = Helpers.GetStringForSSID(network.dot11Ssid);
         ConnectionModel model = new ConnectionModel
         {
              DisplayName = string.Format("{0} (signal {1})", name, network.wlanSignalQuality),
              IsConnected = network.flags.HasFlag(Wlan.WlanAvailableNetworkFlags.Connected),
              SSID = network.dot11Ssid.SSID,
              SsidString = Convert.ToBase64String(network.dot11Ssid.SSID),
              ProfileName = network.profileName,
              Name = name
         };

        if (network.flags.HasFlag(Wlan.WlanAvailableNetworkFlags.HasProfile))
        {
             model.XmlProfile = item.GetProfileXml(model.ProfileName);
        }

        if (network.flags == Wlan.WlanAvailableNetworkFlags.HasProfile)
        {
             model.IsRemembered = true;
        }

        ViewModel.Connections.Add(model);
    }
}

OK now, all the availible APs are in the ViewModel.Connections. Then I can connect one of the AP that Has Profiles:

    private void OnConnect_Handler(object sender, RoutedEventArgs e)
    {
        Button button = sender as Button;
        ConnectionModel model = button.DataContext as ConnectionModel;

        ViewModel.CurrentWlan.SetProfile(Wlan.WlanProfileFlags.AllUser, model.XmlProfile, true);
        ViewModel.CurrentWlan.Connect(Wlan.WlanConnectionMode.Profile, Wlan.Dot11BssType.Any, model.ProfileName);
    }

and it's worked! then I found a problem that is, such code only can connect those APs Has Profile, if I want to connect to a AP without profile(I think that means 'AP never connected'), I should use the following code:

string profileName = model.ProfileName;
string mac = "1008B1CD976F";
string key = "IsThisPasswordField?";
string profile = string.Format("<?xml version=\"1.0\"?><WLANProfile xmlns=\"http://www.microsoft.com/networking/WLAN/profile/v1\"><name>{0}</name><SSIDConfig><SSID><hex>{1}</hex><name>{0}</name></SSID></SSIDConfig><connectionType>ESS</connectionType><MSM><security><authEncryption><authentication>open</authentication><encryption>WEP</encryption><useOneX>false</useOneX></authEncryption><sharedKey><keyType>networkKey</keyType><protected>false</protected><keyMaterial>{2}</keyMaterial></sharedKey><keyIndex>0</keyIndex></security></MSM></WLANProfile>", 
    profileName, mac, key);

ViewModel.CurrentWlan.SetProfile(Wlan.WlanProfileFlags.AllUser, profile, true);
ViewModel.CurrentWlan.Connect(Wlan.WlanConnectionMode.Profile, Wlan.Dot11BssType.Any, profileName);

But I tried serveral times always failed because:

(1) I don't know what the XML content is, why can't just input password then Connect(ssid, password)? is it because WIFI programming doesn't go like this? (2) If must set a profile, how to input the right things such as:

 string mac = "1008B1CD976F";
 string key = "IsThisPasswordField?";

how to know this 'mac', and how to encrypt this key(if it's the AP's password)?

EDIT: here's the Managed Wifi API site. But there's no documentation.

Answer 1

First: The hex-string, you want to insert into the profile is not the mac of the accesspoint, but the hex-string of the ssid. The profile xml is missleading here. I had the same problem, until I converted the hex-string back of a known profile. It was the ssid ;-)

You can just convert the ssid to it's hex representation by so:

string ssid = "YourSSID";
byte[] ssidBytes = Text.Encoding.Default.GetBytes(ssid);
string ssidHex = BitConverter.ToString(ssidBytes);
ssidHex = ssidHex.Replace("-", "");

Second: Because of a wrong hex-string of your ssid, your connection approach with the clear text password did not work either. So just use the hex-representation of the ssid and you can connect with the password in clear text, as you tried before.
