Estou trabalhando no Arch Linux e, em 99% do tempo, conecto à Internet por WLAN, mas às vezes preciso usar uma conexão ethernet, por isso hoje vejo algo estranho. Meu dispositivo eth0 está desativado e não consigo mais. Eu tentei
# ip link set eth0 up
# ifconfig eth0 up
Mas depois de qualquer um dos comandos acima, ip link
mostra:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN mode DEFAULT
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
