Acabei de instalar o BackBox 4.7 2016. No backbox ao vivo enquanto ele estava instalando, eu tinha acesso a vários Pontos de Acesso próximos e, portanto, tinha uma interface eth0. Quando a instalação estava na metade do seu trabalho, meu wifi desapareceu de repente. Eu tentei um monte de comandos que não me lembro agora, mas lembro-me de digitar sudo rfkill unblock all , reiniciar o serviço de rede e assim por diante. Depois disso, minha segunda interface eth0 desapareceu. Minhas interfaces no Win7 funcionam muito bem.
Quando digito sudo ifconfig , ele mostra apenas a interface de loopback local e nada mais. Eu também instalei o linux-firmware-nonfree_1.14 e nada aconteceu depois da reinicialização. Alguma sugestão, pessoal?
Aqui algumas informações:
