Sou novo no Ubuntu. Versão instalada 17.10 ontem e tudo funcionou bem. Hoje tenho problemas com o adaptador Wifi.
Logo após iniciar o PC, ele não encontrará nenhuma rede ou se conectará ao padrão, mas, após alguns minutos, perderá a conexão e não se reconectará ou a encontrará.
Neste ponto, a GUI diz: Redes sem fio não estão disponíveis.
Ethernet funciona bem.
Eu encontrei este skript para diagnosticar o Adaptador, mas não sei o que devo procurar. link
Eu deixo o skript postar a saída para: link
Eu também encontrei este artigo Eu tenho um problema de detecção de hardware, em quais logs eu preciso investigar?
e olhou as coisas sugeridas.
