Ethernet nie działa na Ubuntu 16.04 Dell Vostro

Mam Dell Vostro 3446, podwójnie uruchamiany z systemem Windows 10 i Ubuntu 16.04. Sieć Ethernet działa w systemie Windows, ale nie w systemie Ubuntu, a także nie mogę znaleźć sterowników sieci Ethernet dla systemu Ubuntu na oficjalnej stronie firmy Dell. Działało to wcześniej, ale ostatnio musiałem sformatować i ponownie zainstalować system Windows i Ubuntu.

Twój Ethernet nie uruchamia się, ponieważ sterownik nie załadował się automatycznie zgodnie z oczekiwaniami. Najpierw zobaczmy, czy ustalimy dlaczego. Czy to jest na czarnej liście? Sprawdź z terminala:

grep r8169 /etc/modprobe.d/*

Jeśli znajdziesz wynik, opublikuj go, a ja wyedytuję tę odpowiedź, aby zasugerować poprawkę.

Możemy uzyskać automatyczne ładowanie sterownika za pomocą:

sudo -i
echo r8169 >> /etc/modules
exit

Powinieneś być gotowy.
