使用OID_802_11_DISASSOCIATE断开无线连接失败

    DWORD    dwBytesReturned = 0;

    ULONG    oid = OID_802_11_DISASSOCIATE;

    if (!DeviceIoControl(m_hDevice,
                        IOCTL_NDIS_QUERY_GLOBAL_STATS,
                        &oid,
                        sizeof(oid),
                        ( ULONG *) NULL,
                        0,
                        &dwBytesReturned,
                        NULL))
    {
        char szError[256] = {0};
        sprintf_s(szError, sizeof(szError), "断开失败(错误:%d)", GetLastError());
        m_strErrorInfo = szError;
        goto RELEASE;
    }
GetLastError()返回31。信息为：连到系统上的设备没有发挥作用。
请问我这代码有什么问题？

会不会是原先就根本没连接呢？

不会，我是在无线网卡已经连上一个AP的时候，来测试这函数的

IOCTL_NDIS_QUERY_GLOBAL_STATS is QUERY only and there is no way to set operation to NDIS miniport driver.

You should use native wifi function, e.g., WlanDisconnect, to facilitate this operation.

native wifi函数在XP SP2版本上使用，据说要装一个升级包？？

Here it is.

BTW, the native WiFi functions do not work COMPLETELY on some 802.11 network cards because driver implementation limitation.
