16.04 conexão wifi soltando intel 7265

Question

Ultimamente tenho problemas com o meu wifi (Intel 7265). A conexão com a Internet está saindo a cada dois minutos. Aqui está o dmesg:

Alguém pode me dizer qual é o problema?

    

Answer 1

Sua placa sem fio está caindo para um ponto de acesso diferente. Você pode ver em dmesg que sai 84: a4: 23: 61: 56: 30 para se conectar a 84: a4: 23: 61: 56: 31. Eu suspeito que esses sejam os canais de 2,4 gHz e 5 gHz do seu roteador.

Sugiro que você tente ligar o Network Manager a um ou outro como este: gotas de conexão do Ubuntu. Trabalhou por um tempo e começou a cair novamente

Se isso for ineficaz, renomeie os SSIDs para algo como roteador2.4 e roteador5 . Conecte-se a um e cumpra-o.
