Alguém por favor pode me ajudar? Obrigado!
Algumas coisas para verificar ou lembrar 1. Verifique se outro dispositivo sem fio conectará e navegará. Ethernet é cabeada e um roteador pode funcionar bem usando a Ethernet, enquanto a seção sem fio é kaput. 2. Verifique seu Firewall, pois isso pode bloquear o acesso a conexões sem fio. Parece que o seu computador está funcionando corretamente, você está apenas bloqueado. Você também pode tentar 'dhclient wlan0', que deve redefinir o seu IP e pode corrigir o problema.
