Boa dia a todos, estou tendo um problema que ja venho tentando resolver a mais de uma semana. Um belo dia fui entrar na internet e esta havia parado de funcionar, fui em um outro computador que tem o winxp instalado na mesma rede e a internet estava funcionando. Pensei que poderia ser o cabo de rede, então coloque o que estava no winxp no linux e o problema persistia. Pesso ajuda a vocês conhecedores de linux que me ajudem a resolver este problema. Segue abaixo a lista de comando para que possam entender o meu sistema.
