Eu tenho um servidor com Ethernet com e sem fio. Eu acredito que tudo é bom com os drivers de dispositivos e o WPA2 está configurado corretamente. Eu configurei dois dispositivos usando o system-network-config; eth0 que eu atribuí IP estático 192.168.0.100 e wlan0 que eu atribuí IP estático 192.168.0.101. (Por favor, confirme que com dois NICs devem ter IPs diferentes)
Se eu desconectar o CAT-5 e reiniciar a rede, posso fazer o ping do IP sem fio do servidor (192.168.0.101) de outros PCs na LAN.
No servidor, no entanto, não consigo fazer o ping do roteador ou de outros PCs na LAN. Quando tentei, recebi De 192.168.0.100 icmp_seq=1 Destination host unreachable . Observe que 192.168.0.100 é eth0 e não wlan0.
Assim, parece que meu servidor está configurado para usar apenas eth0. Ou talvez tenha duas interfaces na mesma sub-rede, mas eu realmente não sei. Idealmente, usaria eth0 se conectado, então padrão para wlan0. Como eu faço isso? Obrigado
PS. Desculpe se meu entendimento está incorreto, pois infelizmente estou longe de ser um especialista.
