Conectar-se à rede doméstica cai a Internet após cerca de 10 segundos (Ubuntu 16.04)

  • 772

Hoje tive um problema realmente estranho (e confuso), que não consigo resolver. Quando me conecto à minha rede local (usando ethernet ou wi-fi), a rede parece se conectar bem e as páginas da web são carregadas. Mas depois de cerca de 10 segundos, parece que as páginas não podem mais carregar e vejo o erro cromado 'Não há conexão com a Internet'.

Observe, porém, que a internet ainda está conectada.

Encontrei outros blogs que mencionavam coisas semelhantes, e algumas informações úteis que posso obter estão abaixo.

  1. ping 8.8.8.8 Isso realmente não funciona, apenas retorna o abaixo e congela

    PING 8.8.8.8 (8.8.8.8) 56(84) bytes de dados.

  2. Desativei a ethernet/wifi para ver se a outra funcionava, não funcionou.

  3. Com wifi funcionando, executei ifconfig, que retornou o bloco esperado incluindo a linha de endereço IP

    endereço inet: 192.168.0.1 Bcast:192.168.0.255 Máscara:255.255.255.0

Não tenho certeza de onde tentar a seguir, estava pensando em uma atualização (como estou no Ubuntu 16.04), mas acho que não posso sem uma conexão com a Internet (observe que tenho outros computadores nos quais posso baixar e usar USBs).

Qualquer ajuda seria muito apreciada, pois isso tem sido um problema por meio dia até agora e eu realmente preciso saber como corrigi-lo (espero que sem formatar minha máquina completamente).

Primeiro desativei o wifi, executei este comando e reiniciei. Nada apareceu no cli, a página da web funcionou, mas após ~ 15s de atualização, parou de funcionar novamente.

Adicionando outros domínios DNS, entrei em Rede, selecionei a rede wi-fi à qual estou conectado e adicionei a linha abaixo a 'Servidores DNS adicionais'. Em seguida, reiniciei o gerenciador de rede para testar novamente, infelizmente sem alterações.

    Possível solução (temporária) encontrada. Eu trabalho muito com o Docker e havia muitas redes docker na minha máquina. Correr docker network prunepara remover algumas das redes não utilizadas parece ter ajudado.

    Observe, porém, que não sei por que isso resolveu o problema, talvez houvesse um site docker com um IP duvidoso ou possivelmente apenas a grande quantidade de sites do Docker que eu tinha localmente. Verei se/quando ele voltar e atualizarei este tíquete conforme eu souber mais.
