Модуль r8168, не используемый контроллером ethernet

Я обнаружил, что мой интерфейс eth0 постоянно недоступен (я использую wlan0 для WiFi). После некоторого googling я заменил модуль r8169 на r8168 (apt-get install r8168-dkms), но после перезагрузки не удалось найти строку «Kernel driver in use»:

Теперь интерфейс eth0 отсутствует на выходе ifconfig -a, возможно, потому, что r8168 не был обнаружен при запуске.

Может ли кто-нибудь сказать мне, что я сделал неправильно или забыл? Спасибо заранее!
