сбои соединения eth0
Я становлюсь действительно расстроенным Ubuntu 14.04 в этой точке после необходимости решить столько проблем с ним.
Я использую свой текущий ноутбук на работе, и там это, кажется, на самом деле может соединиться по проводной сети правильно. Но как только я пробую то же дома, оно перестало работать - это, кажется, не находит соединения по eth0, мой более старый ноутбук (с Ubuntu 12) делает очень хорошо с тем же кабелем.
Я понял, что уже существует много вопросов об этой проблеме со многими подобными / различные решения, и прежде, чем записать этот вопрос, я уже протестировал многих из них whitout успех:
Вещи я попробовал в любой комбинации / предложенный в других вопросах в качестве решений:
Я попробовал sudo service network-manager restart, sudo service network-interface restart INTERFACE=eth0 и подобные команды прежде и после редактирований - также перезагрузка компьютера completly несколько раз.
Я отредактировал /etc/network/interfaces, это в настоящее время похоже на это:
auto eth0
iface eth0 inet dhcp
Я отредактировал /etc/resolv.cong и добавил nameserver 8.8.8.8
Я отредактировал /etc/hosts
Я установил managed=true в /etc/NetworkManager/NetworkManager.conf (затем позже, назад к managed=false поскольку это, казалось, не работало),
Я пытался установить фиксированный IP согласно MAC моего ноутбука на моем маршрутизаторе.
Я ничего не могу отредактировать по GUI, все опции (Соединения редактирования..., и т.д.) отображаются серым.
Править: Добавленный ethtool eth0 вывод согласно просьбе. Должен был ввести его вниз вручную, теперь ссылка, по-видимому, не работает на работе ни один (не было никакого изменения на моей стороне, ноутбук был закрыт в течение ночи, и это вчера работало на работе - теперь, у меня нет соединения вообще).
Редактирование 2: Добавленный lscpi производится
Теперь, здесь /var/log/syslog и ifconfig после a sudo service network-manager restart:
