Просто пытаюсь заставить работать мое Ethernet-соединение в Oneiric, и когда я подключаю кабель, оно подключается и отключается бесконечно. /var/syslog говорит следующее (повторяет это снова и снова):

решение1
Поправьте меня, если я ошибаюсь, но похоже, что вы пытаетесь использовать общее соединение. В oneiric есть ошибка по этому поводу. Пожалуйста, посмотрите другой ответ на обходной путь и ссылку на ошибку. Проводное соединение, используемое совместно с другими компьютерами, подключается и отключается в nm-applet Обходной путь — настроить IPv6 на игнорирование при редактировании соединения, а затем выполнить sudo killall dnsmasq
решение2
То же самое происходит, когда я пытаюсь организовать беспроводной интернет-доступ по сети ad hoc на Ubuntu 11.10
sudo killall dnsmasqнаконец-то помогла.
решение3
Выполните диагностику драйвера, щелкнув значок локальной сети, открыв «Сетевой общий доступ», щелкнув «Подключения по локальной сети», «Диагностика».
Мне это помогло. Это сбросит настройки адаптера локальной сети, и он будет работать нормально.
