Eu tenho um Elitebook 8570w rodando o Ubuntu 16.04 e um roteador ac3200. Agora eu tenho o problema mais peculiar com esta configuração: quando estou perto do roteador não consigo me conectar a ele, mas quando vou mais longe, posso me conectar. Quando ele desconecta, ele me pede para me autenticar novamente (preencha a senha novamente). A experimentação demonstrou que não consigo me conectar quando estou a menos de -6 metros do roteador. Isso também parece acontecer quando eu movo o roteador para outro local (por isso não é interferência). Eu também troquei o canal do roteador e isso também não resolveu o problema (tentei os canais 1-4-8-11).
