怎么获取无线网络MAC地址

如何获取无线网络MAC地址？
下面的代码可以获取物理网线连接机器的MAC地址， 但是连接无线网络的笔记本就获取不到MAC， 求大神分析， 我的代码需要怎么改？

STDMETHODIMP CWin32ShellCore::GetMACAddress(BSTR* bstrRet)

{

	CStringA cstrMac;


	IP_ADAPTER_INFO pAdapterInfo; 

	ULONG len = sizeof(pAdapterInfo); 

	if(GetAdaptersInfo(&pAdapterInfo, &len) != ERROR_SUCCESS) 

	{

		LOG_WARN("GetAdaptersInfo ERROR!");


		//GetAdaptersInfo获取失败，尝试用NetBios去获取

		NCB   ncb;     

		UCHAR   uRetCode;   

		int   num   =   0;   

		LANA_ENUM   lana_enum;     

		memset(&ncb,   0,   sizeof(ncb)   );     

		ncb.ncb_command   =   NCBENUM;       // 对网卡发送请求的命令,获取网卡数

		ncb.ncb_buffer   =   (unsigned   char*)&lana_enum;     

		ncb.ncb_length   =   sizeof(lana_enum);     

	    

		struct ASTAT                 //copy头文件中定义

		{

			ADAPTER_STATUS adapt;

			NAME_BUFFER NameBuf[30];

		};


		//向网卡发送NCBENUM命令,以获取当前机器的网卡信息,如有多少个网卡   

		//每张网卡的编号等     

		uRetCode   =   Netbios(&ncb);   

		if   (uRetCode   ==   0)     

		{   

			num   =   lana_enum.length;

			LOG_DEBUG(_T("num = ")<<num);

			//对每一张网卡,以其网卡编号为输入编号,获取其MAC地址

			for(int i = 0; i < num; i++)   

			{   

				ASTAT   Adapter;   

				/*if(GetAddressByIndex(lana_enum.lana[i],Adapter)   ==   0)   

				{   

					pMacAddr[i].b1   =   Adapter.adapt.adapter_address[0];   

					pMacAddr[i].b2   =   Adapter.adapt.adapter_address[1];   

					pMacAddr[i].b3   =   Adapter.adapt.adapter_address[2];   

					pMacAddr[i].b4   =   Adapter.adapt.adapter_address[3];   

					pMacAddr[i].b5   =   Adapter.adapt.adapter_address[4];   

					pMacAddr[i].b6   =   Adapter.adapt.adapter_address[5];   

				}   */

				memset(&ncb,0,sizeof(ncb));    //使用之前要使ncb结构清0

				ncb.ncb_command=NCBRESET;      //对选定的网卡发送命令,以便进行初始化

				ncb.ncb_lana_num=lana_enum.lana[i];

				uRetCode=Netbios(&ncb);

				//

				memset(&ncb,0,sizeof(ncb)); 

				ncb.ncb_command=NCBASTAT;

				strcpy((char*)ncb.ncb_callname,"*");

				ncb.ncb_buffer=(UCHAR*)&Adapter;

				ncb.ncb_length=sizeof(Adapter);

				//接着发送命令获取网卡信息

				uRetCode=Netbios(&ncb);

				if(uRetCode==0)

				{

					char mac[15];

					sprintf(mac,"%02X%02X%02X%02X%02X%02X",

							Adapter.adapt.adapter_address[0],

							Adapter.adapt.adapter_address[1],
