무선 드라이버가 감지되지 않음

iwconfig를 입력하면 "무선 확장 없음"만 표시됩니다.

Ubuntu 무선 드라이버를 감지하려면 어떻게 해야 합니까?

답변1

출력에는 sudo rfkill list네트워크 카드가 "소프트 차단"되어 있음이 표시됩니다.

무선 카드가 꺼지라는 신호를 받았을 때 이런 일이 발생할 수 있습니다. 이는 아마도 Fn+ 유형 스위치 때문일 것입니다.

키보드 스위치를 식별할 수 없는 경우 다음 단계를 수행하십시오.

  1. 터미널에서 실행:

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

  2. 다시 실행하여 sudo rfkill list카드가 차단 해제되었는지 확인하세요.

  3. 재부팅

  4. 다시 실행하여 sudo rfkill list차단 해제가 유지되었는지 확인하세요.

  5. 다시 실행 sudo lshw -class network- 이제 커널이 무선 카드를 인식했는지 여부를 확인할 수 있습니다.

무선 커널 모듈이 인식된 경우("청구되지 않음"이라고 표시되어서는 안 됨) 이제 Network Manager는 귀하의 공간에서 사용 가능한 무선 네트워크를 볼 수 있습니다.
