WlanGetAvailableNetworkList函数为什么搜索不到未连接过的wifi信息

[大师救我10086]

以下是源码
m_dwResult = WlanScan(m_hClient,&m_pIfList->InterfaceInfo[0].InterfaceGuid,NULL,NULL,NULL);
Sleep(4000);
//由可用列表便可以找到当前哪个AP正在连接，并显示信号强度。
m_dwResult = WlanGetAvailableNetworkList(m_hClient, &m_pIfList->InterfaceInfo[0].InterfaceGuid,
WLAN_AVAILABLE_NETWORK_INCLUDE_ALL_ADHOC_PROFILES,
NULL, &pWLAN_AVAILABLE_NETWORK_LIST);
if (m_dwResult != ERROR_SUCCESS)
{
printf("WlanGetAvailableNetworkList failed with error: %u\n",m_dwResult);
str = L"WlanGetAvailableNetworkList failed with error:" + m_dwResult;
addmessage(str);
WlanFreeMemory(pWLAN_AVAILABLE_NETWORK_LIST);
return;
//return -1;
}

WLAN_CONNECTION_PARAMETERS wlanConnPara;
wlanConnPara.wlanConnectionMode =wlan_connection_mode_profile ; //YES,WE CONNECT AP VIA THE PROFILE
wlanConnPara.strProfile =m_pProfileName; // set the profile name ssid
wlanConnPara.pDot11Ssid = NULL; // SET SSID NULL
wlanConnPara.dot11BssType = dot11_BSS_type_infrastructure; //dot11_BSS_type_any,I do not need it this time.
wlanConnPara.pDesiredBssidList = NULL; // the desired BSSID list is empty
wlanConnPara.dwFlags = WLAN_CONNECTION_HIDDEN_NETWORK; //it works on my WIN7\8
m_dwResult=WlanConnect(m_hClient,&m_pIfList->InterfaceInfo[0].InterfaceGuid,&wlanConnPara ,NULL);


在我用WlanScan进行4s搜索之后，再用WlanGetAvailableNetworkList去获取wifi信息，不知道为什么只能获取到曾经已经连接过的wifiAP，但是其他从未连接过的信息是获取不到的，同样的，WlanConnect也是连接不上以前没有连接过的wifi，返回errorcode 87
萌新请问到底是为什么？

The WlanScan function returns immediately. To be notified when the network scan is complete, a client must register for notifications by calling WlanRegisterNotification.
