New Post: How to turn radio off/on?

cityking — Tue, 04 Aug 2009 08:17:14 GMT

How can we turn wifi radio on/off with native wifi or managed wifi?

I have seen that it's simple when using VISTA, however, I want to do this on Windows XP.

Can anyone tell me how can I manage to do it?

I have tried many IOCTL OIDs... but ... can not...

New Post: InterfaceState.Connected not being set?

cmayen — Mon, 03 Aug 2009 21:27:23 GMT

Hello all,

First, thanks for this great API, I had a wild idea and this made it much easier since i didnt neet to handle creating a wireless manager. However... after sending the command to connect to the wireless access point, the interface state does not seem to be updating all the way to Connected. Using the following code in a timed loop to monitor it, i've noticed the interface state always shows as "Authenticating."

It could be something silly that i have missed, any help would be appreciated! Thanks!

The function below is always returning false, even after successful connections are established.

        public bool wirelessConnectedToProfile(string profileName)
        {
            WlanClient client = new WlanClient();
            foreach (WlanClient.WlanInterface wlanIface in client.Interfaces)
            {
                Console.WriteLine("WlanInterfaceState: " + wlanIface.InterfaceState.ToString());
                if (wlanIface.InterfaceState == Wlan.WlanInterfaceState.Connected)
                {
                    if (wlanIface.CurrentConnection.profileName == profileName)
                    {
                        return true;
                    }
                }
            }
            return false;
        }

New Post: About Wlan connect

cityking — Thu, 23 Jul 2009 02:54:45 GMT

Hi, everybody,

This is a very perfect API. I have a question here that I don't know how to use the function "Connect(Wlan.WlanConnectionMode connectionMode, Wlan.Dot11BssType bssType, string profile)" to connect to a specific network... How should I set the parameters? Can anyone provide me an example of Connect to a specific network ? thank you very much!

I have tried the codes bellow, but got the Win32Exception, the error is located at the Connect function, maybe the parameters are invalid.

//=======================================================================

namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

WlanClient WC = new WlanClient();

//We must define the flags for using the "GetAvailableNetworkList" function.

Wlan.WlanGetAvailableNetworkFlags flag = new Wlan.WlanGetAvailableNetworkFlags();

//refreshing the network list.

WC.Interfaces[0].Scan();

//The array that contains the networks details.

Wlan.WlanAvailableNetwork[] WList;

WList = WC.Interfaces[0].GetAvailableNetworkList(flag);

foreach (Wlan.WlanAvailableNetwork ssid in WList)

{

Console.WriteLine("SSID is : " + Encoding.ASCII.GetString(ssid.dot11Ssid.SSID));

//Console.Read();

}

WC.Interfaces[0].Connect(Wlan.WlanConnectionMode.Profile, Wlan.Dot11BssType.Any, null);

}

namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

WlanClient WC = new WlanClient();

//We must define the flags for using the "GetAvailableNetworkList" function.

Wlan.WlanGetAvailableNetworkFlags flag = new Wlan.WlanGetAvailableNetworkFlags();

//refreshing the network list.

WC.Interfaces[0].Scan();

//The array that contains the networks details.

Wlan.WlanAvailableNetwork[] WList;

WList = WC.Interfaces[0].GetAvailableNetworkList(flag);

foreach (Wlan.WlanAvailableNetwork ssid in WList)

{

Console.WriteLine("SSID is : " + Encoding.ASCII.GetString(ssid.dot11Ssid.SSID));

//Console.Read();

}

WC.Interfaces[0].Connect(Wlan.WlanConnectionMode.Profile, Wlan.Dot11BssType.Any, null);

}

//============================================================

How should I set the parameters? my OS is Windows XP SP3.

New Post: How to convert Passphrase to Hex

bradman — Thu, 25 Jun 2009 13:54:47 GMT

Hello,

This is pretty cool library. I am planning to use this in our application to allow users to browse wireless networks, and allow them to connect to a secured wireless network (WEP, WPA or WPA2).

The question I have is, how do I convert the user entered passphrase to a 64 hex digits in case of WPA?

Are there any built-in .Net types/methods available to achieve this?

Any help/suggestions grealy appreciated

Thanks

New Post: Does this API work with non-WZC drivers?

rherrick — Wed, 03 Jun 2009 04:51:12 GMT

I've gotten the ManagedWiFi API to work with the standard Windows wireless network connection stuff. But I have a Dell laptop that has the Dell Wireless WLAN card utility running the wireless connection and when that's going, I get this error:

System.ComponentModel.Win32Exception: The service has not been started
   at NativeWifi.Wlan.ThrowIfError(Int32 win32ErrorCode)
   at NativeWifi.WlanClient..ctor()
   at LessNetworks.Scoop.ConnectionInfo.WapConnectionInfo.Update() in C:\Development\Scoop\trunk\Scoop\ConnectionInfo\WapConnectionInfo.cs:line 28

This is dependent on using the WINDOWS wifi stuff and not any old wifi management utility, isn't it? Is there any way to get info about wireless connections regardless of what's managing that connection? Do I have to go through NDIS or something?

On Interop.cs you should add :

[DllImport("wlanapi.dll")]
public static extern int WlanDisconnect(
[In] IntPtr clientHandle,
[In, MarshalAs(UnmanagedType.LPStruct)] Guid interfaceGuid,
IntPtr pReserved);

And on WlanApi:

/// <summary>
/// Disconnects to a network
/// </summary>
public void Disconnect()
{

Wlan.ThrowIfError(
Wlan.WlanDisconnect(client.clientHandle, info.interfaceGuid, IntPtr.Zero));
}

With these you'll be able to call the Disconnect method!! ;)
