When trying to connect a two FEZ boards (Feather and Portal) via wifi, an exception is thrown.

Setup:

Feather (setup as Access Point) Wifi Code:

public static GpioPin led;

 static void Main()
 {
     led = GpioController.GetDefault().OpenPin(SC20260.GpioPin.PE11);
     led.SetDriveMode(GpioPinDriveMode.Output);

     InitializeWifi();
 }

  public static void InitializeWifi()

Portal (setup as Station) Wifi Code:

    var gpioControllerName = SC20260.GpioPin.Id;

    var gpio = GpioController.GetDefault();
    var enablePin = gpio.OpenPin(enablePinNumber);
    enablePin.SetDriveMode(GpioPinDriveMode.Output);
    enablePin.Write(GpioPinValue.High);

    };
    networkCommunicationInterfaceSettings.SpiApiName = spiControllerName;
    networkCommunicationInterfaceSettings.GpioApiName = gpioControllerName;
    networkCommunicationInterfaceSettings.SpiSettings = settings;
    networkCommunicationInterfaceSettings.InterruptPin = gpio.OpenPin(irqPinNumber);
    networkCommunicationInterfaceSettings.InterruptEdge = GpioPinEdge.FallingEdge;
    networkCommunicationInterfaceSettings.InterruptDriveMode = GpioPinDriveMode.InputPullUp;
    networkCommunicationInterfaceSettings.ResetPin = gpio.OpenPin(resetPinNumber);
    networkCommunicationInterfaceSettings.ResetActiveState = GpioPinValue.Low;
    networkController.SetCommunicationInterfaceSettings(networkCommunicationInterfaceSettings);

    string[] ssidList = Winc15x0Interface.Scan();
    foreach (var s in ssidList)
        Debug.WriteLine(s);

    WiFiNetworkInterfaceSettings networkSettings = new WiFiNetworkInterfaceSettings();
    networkSettings.Ssid = "StableSwitch Net";
    networkSettings.Password = "0123456789";
    networkSettings.Mode = WiFiMode.Station;
    networkSettings.Channel = 6;

    networkSettings.DhcpEnable = true;
    networkSettings.DynamicDnsEnable = true;
    networkController.SetInterfaceSettings(networkSettings);
    networkController.SetAsDefaultController();

   //this is where the exception is thrown....
    Debug.WriteLine("Enable the network controller.");
    try
    {
        networkController.Enable();
    }
    catch (Exception e) {
        Debug.WriteLine(e.ToString());
    }

    Debug.WriteLine("Network controller is enabled.");

    networkController.NetworkAddressChanged += NetworkController_NetworkAddressChanged;

    //just a pause for test in debug
    while (true)
    {
        Thread.Sleep(100);

    }

    IPHostEntry ip = Dns.GetHostEntry("GHIElectronics.com");
    Debug.WriteLine("GHI Electronics' IP = " + ip.AddressList[0].ToString());

}

private static void NetworkController_NetworkAddressChanged(NetworkController sender, NetworkAddressChangedEventArgs e)
{
    //throw new NotImplementedException();
    var ipProperties = sender.GetIPProperties();
    Debug.WriteLine("IP: " + ipProperties.Address);
    var address = ipProperties.Address.GetAddressBytes();

}

When trying to connect the Portal as a client to the Feather, the following exception is thrown when enabling the netWorkController on the Portal.


Enable the network controller.
    #### Exception System.ArgumentException - 0xfd000000 (1) ####
    #### Message:

Exception thrown: 'System.ArgumentException' in GHIElectronics.TinyCLR.Devices.Network.dll

Note, I am able to connect my phone to the Feather Access Point and I am able to connect the Portal to my house wifi without trouble.

I remove the wifi password from both the Feather and Portal and the systems connect and provides an IP address to the client. However, the AccessPointClientConnectionChanged event does not fire. When I connect via my phone, the event does fire.
