Question

I just got a cubox-i4 but have a big problem with the LAN connection. It establishes and crashes again. The thing is, that if I connect it via LAN to an Airport Express (connected via wifi), the connection is stable (=> no hardware problem). Direct Connection to the router is not working. Here is the log when connected to the router:
