Venho pedir a ajuda de vocês, pois quando estou conectado ao wi-fi pelo notebook, do nada desconecta e aparece a seguinte de mensagem de notificação : FALHA DE CONEXÃO - FALHA AO ATIVAR A CONEXÃO DE REDE. Após desconectar só consigo encontrar rede disponível e me conectar se eu desligar e ligar o notebook.
Uso ubuntu 18.04 LTS
Desde já agradeço

E poste aqui o resultado.

Para podermos ajudar, precisamos saber qual é o hardware de rede sem fio do seu computador.
