Instalei o CentOS, mas ele não se conectou automaticamente à Internet. Esse é o comportamento normal? Eu tenho Ethernet Broadband Router DI-604 e WebStar DPX2203 série Cablemodem com EMTA. O que devo fazer para me conectar à internet?
Atualização:
Uma prima me disse que meu adaptador de ethernet ou placa de rede dependerá da minha placa-mãe. Meu documento de atualização do computador diz que a placa-mãe é de vídeo GBabyte onboard. Ouvi dizer que os adaptadores de rede do GBabyte são GBabit ou Realtek.
No CentOS, Sistema - > Administração - > Rede - > Novo - > Ethernet, primeiro, apenas "Other Network Board" foi listado, então eu selecionei e cliquei em Next, então não havia GBabit, mas havia o Realtek, então eu selecionei o Realtek.
Eu ouvi com Net Virtua selecionando dhcp as coisas primeiro respondidas me pediram para dizer primeiro respondedor são configuradas automaticamente.
Então, experimentei o Realtek com dhcp
, mas eth0
não foi encontrado.
Veja asteriscos:
nós não atualizamos esse tempo, a placa-mãe é a Asus. /sbin/lspci -v
mostra que o controlador Ethernet é Atheros L2, o subsistema é Asustek .
