MBN Api: интерфейсы не найдены при использовании mbnInfMgrInterface.GetInterfaces()

Question

Добрый день

У меня странная проблема при использовании API мобильной широкополосной сети (MBN API). При использовании netshell и запуске netsh mbn>show interfaces я получаю 1 интерфейс. Это правильно, потому что у меня есть одно широкополосное соединение в моей системе.

Когда я иду к своему коду (который работает в других системах), и я делаю

IMbnInterface[] mobileInterfaces = mbnInfMgrInterface.GetInterfaces() as IMbnInterface[];

Я не получаю интерфейсы.

Разве это не должно быть как-то связано? Есть ли особая настройка, которую я забыл?

Моя функция readstate:

private void ReadStateMobileNetwork()
    {
        Log.Info("Reading mobile network state");
        try
        {
            MbnInterfaceManager mbnInfMgr = new MbnInterfaceManager();
            IMbnInterfaceManager mbnInfMgrInterface = mbnInfMgr as IMbnInterfaceManager;
            if (mbnInfMgrInterface != null)
            {
                IMbnInterface[] mobileInterfaces = mbnInfMgrInterface.GetInterfaces() as IMbnInterface[];
                Log.Info("Interfaces: " + mobileInterfaces);
                if (mobileInterfaces != null && mobileInterfaces.Length > 0)
                {
                    // Use the first interface, as there should only be one mobile data adapter
                    IMbnSignal signalDetails = mobileInterfaces[0] as IMbnSignal;

                    Int32.TryParse(signalDetails.GetSignalStrength().ToString(), out _signalStrength);
                    SignalStrength = Convert.ToInt32(((float)SignalStrength / 33) * 100);

                    MBN_PROVIDER provider = mobileInterfaces[0].GetHomeProvider();
                    MobileProvider = provider.providerName.ToString();

                    if (String.IsNullOrEmpty(SIMkaartnumber))
                    {
                        try
                        {
                            IMbnSubscriberInformation subInfo = mobileInterfaces[0].GetSubscriberInformation();

                            if (subInfo != null)
                            {
                                SIMkaartnumber = subInfo.SimIccID;
                            }
                            else
                            {
                                Connected = false;
                                SIMkaartnumber = "";

                                SignalStrength = 0;
                                State = MobileNetworkMonitorState.UnableToReadSimInfo;

                        }
                    }

Спасибо за помощь. Надеюсь, кто-то сталкивался с этой проблемой раньше и сможет мне помочь.
