O comando
dmesg | grep eth
[ 0.793336] i2c-core: driver [aat2870] using legacy suspend method
[ 0.793338] i2c-core: driver [aat2870] using legacy suspend method
Não lista nenhuma eth0 / eth1 / eth2 etc.
No entanto,

Existe algum problema com os drivers ou algo mais?
Qualquer ajuda seria muito apreciada.
(atualização)
Meu amigo tentou fazer algo novamente. E minha conexão com fio está funcionando agora.
lshw -C network
