O dispositivo sem fio é exibido e está ativado no Network Manager, mas nenhuma rede é exibida.
Isso acontece com frequência e sem motivo visível.
Quando eu desligar o computador, desconecte o cabo de energia, conte até dez, reconecte o cabo de energia e ligue o computador novamente. A lista de redes sem fio fica disponível novamente. Se eu não desconectar o cabo de energia, essa solução alternativa não funciona.
Isso muitas vezes aconteceu há algum tempo. Minha máquina não tem uma tecla de atalho para ativar / desativar a rede sem fio, eu ainda não tinha a solução "desconectar cabo de energia", então a solução foi reiniciada no Windows (inicialização dupla), habilitar a rede sem fio no controle painel e de volta para o Ubuntu.
Como posso ter minha rede sem fio funcionando novamente sem nenhuma dessas soluções estranhas?
