Проблема проводного соединения Ubuntu 14.04 LTS

Я недавно добавил раздел к своему компьютеру с Ubuntu 14.04 64-разрядный LTS.

Это - Турбо-X двойная загрузка с Windows 7. Работы Ethernet, хорошие в Windows, но в Ubuntu, не работают.

Проводное соединение пытается соединиться с переключателем все время, но это не соединяется.
