[ solved ] LAN won't stay connected

[oskarn97Member]

Hello,

I just got my cubox-i4 but LAN isn’t working at all. The connection interrupts after some seconds and reestablished. Internet and Mac is sometimes “busy”. Please help me!

Edit:

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:
