Driver sem fio não detectado

Question

Ao digitar iwconfig, eu só recebo "sem extensões sem fio"

Como obtenho o driver sem fio do Ubuntu para ser detectado?

Answer 1

A saída para sudo rfkill list mostra que sua placa de rede é "bloqueada por software".

Isso pode acontecer quando a placa sem fio foi sinalizada para desligar - provavelmente por causa de um comutador do tipo Fn +.

Se você não identificar o teclado, execute as seguintes etapas:

1. executado em um terminal:

   sudo rfkill unblock hp-wifi; sudo rfkill unblock wifi; sudo rfkill unblock all

2. reexamine sudo rfkill list para confirmar que o cartão foi desbloqueado.

3. reboot

4. reexamine sudo rfkill list novamente para confirmar que o desbloqueio foi mantido.

5. rerun sudo lshw -class network - você deve ver agora que o kernel reconheceu (ou não) a placa wireless.

Se o módulo do kernel sem fio tiver sido reconhecido (não deverá dizer "não reivindicado"), o Network Manager agora poderá ver as redes sem fio disponíveis em seu espaço de tempo.
