Ambas as redes Ethernet e Wifi estão desconectadas de cerca de 3 horas antes de postar esta pergunta na minha máquina do Ubuntu 16.04. Coisas que eu tentei ler antes de postar aqui:
sudo service network-manager restart - > não está funcionando sudo touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf_orig e sudo service network-manager restart - > não está funcionando Eu noto que, por exemplo, em "Configurações do Sistema > Redes", o cabo diz desconectado. Mas eu tenho o cabo ligado e essa é a primeira coisa que eu verifiquei. Mesmo que minha rede a cabo esteja inoperante, por que Wifi? É possível que a porta Ethernet física e o adaptador wi-fi tenham sido ruins? Eu até tentei atualizar meus drivers de realtek como determinado aqui .
Por favor, ajude-me a resolver este problema. Se houver algo que eu esteja sentindo falta aqui, por favor, indique.
Alguns detalhes que podem ser úteis: nmcli dev
