A conexão sem fio está desativada por hardware

1

Eu tentei usar o Wi-Fi no meu notebook, mas apareceu uma mensagem "O dispositivo sem fio está desativado por hardware"

Eu tentei alterar o interruptor físico, mas não o corrigi. E use fn também, mas nada corrigiu esse problema com o hardware.

Meu notebook é um Philco PHN14005 e eu uso um Ubuntu 14.04 64 bits.

Como posso consertar este hardware wifi?

sudo apt-get purge bcmwl-kernel-source e, em seguida, sudo apt-get install firmware-b43-installer e reinicialize. Se não funcionar após a reinicialização, adicione os resultados de lsmod | grep -e wmi -e laptop

Você pode por favor experimentar o comando abaixo

sudo rmmod -f dell-laptop

sudo rfkill desbloquear todos

Verifique se funcionou

Acho que isso pode ser semelhante ao seu problema.

Sem fio aparece desativado, como posso fazê-lo funcionar?

a solução foi:

sudo rm /dev/rfkill && sudo reboot
