Eu tenho tido muitos problemas em fazer com que meu wireless funcione de maneira confiável no meu Dell XPS 15z. Há muita conversa sobre isso em outro fóruns , e parece ter algo a ver com o Bluetooth interferindo no Wireless.
Então, para explicar onde estou: posso me conectar por cerca de 15 minutos antes que ele se desconecte e não se conecte novamente. Selecionar minha rede na lista apenas faz com que ela fique lá por um tempo antes de me pedir novamente a senha .
A outra coisa que é muito estranha e MUITO irritante é que se eu desabilitar o Bluetooth através do painel do gnome ( B
- > Desativar o Bluetooth), ele desligará ambos o bluetooth e o sem fio, e ENTÃO não posso ligá-lo novamente porque ele alega que "a rede sem fio está desativada por meio da troca de hardware" e o mesmo acontece com o Bluetooth. Mesmo reiniciar daqui não ajuda. O interruptor de hardware real ( fn + F2 ) não faz nada, a menos que eu inicie no Windows, o que obviamente é menos do que satisfatório.
Então! Eu não uso nenhum dispositivo Bluetooth, então se eu realmente desativá-lo, o wireless pode voltar. Mas eu não sei como fazer isso ...
Qualquer ajuda ou conselho?
