Ethernet, не работающий (ни один даже обнаруженный) на Ubuntu 12.04

Ethernet не обнаруживается на моем компьютере под управлением Ubuntu 12.04 с ЛАМПОЙ. Последняя вещь, которую я не забываю делать, следует этому учебному руководству: http://www.howtoforge.com/linux-basics-set-a-static-ip-on-ubuntu

Вот проверки, которые я выполнил. Надежда это могло помочь.Спасибо!
