Eu tenho lido outros tópicos e tentando as etapas sugeridas, mas nada parece funcionar para mim. 50% do tempo que a internet funciona bem, às vezes diminui a velocidade, às vezes não há conexão alguma. O problema mais comum parece ser "conectividade IPv6: sem acesso à rede" às vezes: o IPv4 exibe a mesma mensagem às vezes diz "rede não identificada" ou "acesso limitado à rede".
Eu copiei as especificações do meu computador, se isso for de alguma utilidade. Seria ótimo se o sb fosse capaz de me ajudar com isso.
Eu postei o terceiro ipconfig log para quando não há absolutamente nenhuma conexão (na parte inferior)
