Соединитесь с Интернетом на Ubuntu 14.10

Я недавно загрузил Ubuntu 14.10 на своем HP Pavilion. Я пытаюсь соединиться с Интернетом проводным соединением, но Ubuntu не распознает плату Ethernet.

Когда я следую инструкциям в:

http://www.pcworld.com/article/2455972/how-to-fix-your-internet-connection-in-ubuntu-linux.html

Сначала это говорит, что "Кабель отключил" для Проводного соединения - хотя кабель соединен - также кнопка "сохраняет" все еще закрытый даже после редактирования вручную Настроек IPv4.

С наилучшими пожеланиями.

Вот вывод lspci
