I have new Mac Mini. He worked well in Internet. Then began issuing common IP-address local 168. *. *. *. Occasionally assisted on-off cable and IP-address appear correctly. Turn cable to the laptop Lenovo G550 - works. Turn cable to the Mac Mini - Ethernet is not connected [/ b].

Opened in WindowsBootcamp. A network cable is connected. Repair of drivers in the Windows did not help.
