I can run Ethernet code using a NETMF project, as in code from GHI documentation, but when I run a NET Gadgeteer project using Ethernet J11D module, the network up event never fires.
Output of code that follows:
Ethernet cable is connected!
Enable DHCP
Network settings:
IP Address: 192.168.1.200
Subnet Mask: 255.255.255.0
Default Getway: 192.168.1.1
DNS Server: 192.168.1.1
Test Request
