Ubuntu 14.04 ifconfig не показывает eth0

У меня Ubuntu 14.04 LTS на Asus EeePC 1215b, и я не могу подключиться к проводному интернету. Я знаю, что это не настройка BIOS (Lan включен). Я попытался узнать больше о состоянии соединения, поэтому я нашел следующие решения:

Я действительно не знаю, как снова заставить работать мое проводное соединение. Пожалуйста, кто-нибудь может мне помочь?
