나는 여러 날 동안 Wi-Fi를 사용해 왔지만 오늘 네트워크 관리자에는 Wi-Fi 활성화 옵션이 표시되지 않습니다. Wi-Fi 작동이 중단되기 전에 Wi-Fi 토글을 여러 번 눌렀습니다. 이전에 사용 가능한 네트워크가 표시되었지만 이제는 발견된 네트워크 확장이 표시되지 않습니다.
다음에 대한 출력이 없습니다.
lspci -knn | grep Net -A2 && rfkill 목록.

터미널에서 이 명령을 실행 sudo rfkill list all하고 소프트 차단된 항목이 있는지 확인하세요. 무선 LAN이 소프트 차단된 것으로 확인되면 를 입력합니다 sudo rfkill unblock all.
