Eth0 faltando no Linux 3.18.8 com cartão Realtek onboard

Question

A Ethernet desapareceu completamente em um laptop com o Linux Mint Cinnamon 64 e o Kernel 3.18.8. Eu instalei o driver realtek em seu site, mas isso não está resolvendo o problema.

ifconfig -a apenas lista lo , wlan0 e não esse controlador como eth0 ou algo semelhante.

sudo lspci -v mostra que nenhum módulo do kernel está em uso:

finalmente sudo lshw -numeric -C network me dá:

Answer 1

Instalar o pacote Debian para a placa Ethernet resolve o problema. link

Dito isto, não será necessário instalar o pacote Debian, já que o Kernel deve fornecer a placa Ethernet. No entanto, não funcionou sem. Depois de instalar o Kernel 4.0, tive o mesmo problema novamente.
