Oi Josimar,

Por favor, pode coletar um sosreport depois que o problema acontecer algumas vezes (por exemplo, 24 horas com o notebook ligado), e anexar nesse bug?

$ sudo sosreport --batch --case-id lp1880639

O arquivo será algo como /tmp/sosreport-*-lp1880639-2020-*.tar.xz

Seu kernel log mostra 2 mensagens interessantes do driver de wi-fi; gostaria de ver se elas sao consistentes entre os eventos de desconexão.
