Por anos eu usei uma conexão física de Ethernet para o meu acesso à internet, então alguns dias atrás ele caiu e disse que era uma rede não identificada sem acesso à internet. Eu tirei uma placa wifi e liguei e funciona (não é ideal devido à distância do roteador, mas ele se conecta). Os outros computadores conectados via wifi / cabo também funcionam.
Eu desinstalei e reinstalei a placa de rede, atualizei os drivers, reiniciei a pilha TCP / IP, libertei e renovei o endereço IP, habilitei o DHCP, verifiquei as configurações do firewall, removi e reinstalei o antivírus, configurei manualmente o IP e o gateway padrão ainda nada ...
Quando você executa o recurso de diagnóstico no Windows, ele retorna: "Ethernet 2" não possui uma configuração IP válida. Não corrigido.
