Ubuntu 12.04 не показывает проводное соединение, Windows 7 делает [закрыт]

У меня есть проводное соединение в моей студенческой общежитии, которая не появляется в сетевом менеджере с 12.04. Он действительно работает с Windows 7, поэтому я не говорю о каком-либо аппаратном обеспечении.

На запасном разделе на моем HD я попытался установить еще 12.04, просто чтобы убедиться, что это не какая-то конфигурация моего ошибочный: получается, он тоже не работает.

Самое смешное, что NM признал связь до вчерашнего дня, поэтому я подумал, что с этим связано некоторое обновление, но в журналах ничего не было что, похоже, может сломать что-то связанное с сетью.

My /etc/NetworkManager/NetworkManager.conf

[main]
plugins=ifupdown,keyfile
dns=dnsmasq

[ifupdown]
managed=false

My /etc/network/interfaces

auto lo
iface lo inet loopback

auto eth0
#iface eth0 inet dhcp

Я не знаю, почему прокомментирована последняя строка, но я попробовал раскомментировав его, но это не сработает, и еще хуже будет сказать, что «устройство неуправляемо». Затем я попытался установить managed=true, но он вернулся к тому, чтобы не распознавать соединение, поэтому я просто все вернул.

ifconfig eth0:
