Hallo, i have a problem with Network connectivity from FEZ CerbuinoNet board. When I using the Board with Netmf4.3 and GHI SDK 2015 R1 is by following Code no response by ping to the board. The same Code and board with Netmf4.2 and GHI SDK 2015 R1 and Board answers by ping. With Monutaineer Eth 1 give no Problem, this Board answers by Netmf4.2 + Netmf4.3 correctly. The Firmware is in each case on topical state.

I hope you can help
many thanks

@ Leuthold -
I am not sure if your code still correct for 4.3 because a lot of change from 4.2 to 4.3.
But, you can try our example from here:
https://www.ghielectronics.com/docs/30/networking
There is no ENC28 but ENC28 is same Wifi, just has no Join() function.
More detail is below:
using GHI.Networking;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using Microsoft.SPOT.Net.NetworkInformation;
using System;
using System.Net;
using System.Threading;
public class Program
{
private static EthernetENC28J60 netif;
public static void Main()
{
bool useDHCP = false;
NetworkChange.NetworkAvailabilityChanged += NetworkChange_NetworkAvailabilityChanged;
NetworkChange.NetworkAddressChanged += NetworkChange_NetworkAddressChanged;
netif = new EthernetENC28J60(SPI.SPI_module.SPI1, chipSelectPin, externalInterruptPin, resetPin);
if (useDHCP == false)
{
Debug.Print("Set static IP...");
netif.EnableStaticIP("x.x.x.x", "x.x.x.x", "x.x.x.x");
netif.EnableStaticDns(new string[] { "x.x.x.x", "x.x.x.x" });
}
else
{
Debug.Print("Get DHCP IP...");
//// DHCP IP
if (netif.IsDhcpEnabled == false)
{
netif.EnableDhcp();
netif.EnableDynamicDns();
}
}
Debug.Print(Opening ...");
netif.Open();
while (!isReady )
{
Thread.Sleep(250);
}
Debug.Print(Network is ready to use...");
Thread.Sleep(-1);
}
static bool isReady = false;
private static void NetworkChange_NetworkAddressChanged(object sender, Microsoft.SPOT.EventArgs e)
{
Debug.Print("Network address changed");
Debug.Print("Is DhCp enabled: " + netif.NetworkInterface.IsDhcpEnabled);
Debug.Print("Is DynamicDnsEnabled enabled: " + netif.NetworkInterface.IsDynamicDnsEnabled);
Debug.Print("NetworkInterfaceType " + netif.NetworkInterface.NetworkInterfaceType);

Debug.Print("IP Address: " + netif.NetworkInterface.IPAddress);
Debug.Print("Subnet Mask: " + netif.NetworkInterface.SubnetMask);
Debug.Print("Default Gateway: " + netif.NetworkInterface.GatewayAddress);

{
Debug.Print(" " + netif.NetworkInterface.PhysicalAddress[i].ToString());
}
Debug.Print("Number of DNS servers:" + netif.NetworkInterface.DnsAddresses.Length);
for (int i = 0; i < netif.NetworkInterface.DnsAddresses.Length; i++)
Debug.Print("DNS Server " + i.ToString() + ":" + netif.NetworkInterface.DnsAddresses[i]);
