Można zredukować prędkość z obecnego 1Gbps do 100mbps lub 10mbs. Można też bawić się ustawieniem duplexu ale na początek może wystarczy sama prędkość.
Na moim przykładzie (w Twoim przypadku zmieniasz eth1 na enp12s0):
Zmiana na 10:

Kod:

$sudo ethtool -s eth1 autoneg off speed 10

Podgląd czy speed zmieniło się na 10:

Kod:

$ethtool eth1
