Wi-Fi 카드가 작동하지 않음, rfkill 하드 블록, modprobe가 작동하지 않음, 레거시 드라이버 재설치, 재부팅 등.

첫 글이라 게시 위치나 형식 등 수정해야 할 부분이 있으면 알려주세요.

간단히 말해서, 내 Wi-Fi 카드(Intel Centrino Wireless-N 2200)가 lshw -class netowkr작동을 멈췄는데 솔직히 어떻게 해결해야 할지 모르겠습니다. 이 문제를 해결하는 데 도움이 될 수 있는 여러 명령의 출력을 포함시켰습니다. 추가 정보가 필요한 경우 알려주시기 바랍니다.

Thinkpad x230에서는 Fn + F5를 눌러 Wi-Fi를 전환할 수 없습니다. Fedora에서 비행기 모드를 켜는 것은 Wi-Fi 기능이 손상될 수 있는 일반적인 실수라는 것을 언급한 것을 보았습니다.

내가 시도한 것:
- sudo rfkill unblock all
재부팅
- 커널 5.5.6에서 5.5.7 및 5.5.8로 업그레이드되었습니다. 문제는 모든 커널 버전에 존재하며
그 sudo rmmod iwldvm뒤에는 sudo modprobe iwldvm. 그 후 rfkill은 하드 차단되지 않았지만 Wi-Fi 활성화 시도가 실패했음을 보여줍니다.
GUI를 사용하여 Wi-Fi를 활성화하고
BIOS에서 wlan을 비활성화한 다음 다시 활성화하여
BIOS에서 모든 무선 관련 설정을 활성화합니다. Bluetooth 및 WWAN 활성화 여부에 관계없이 Wi-Fi가 작동하는 것 같습니다.
- 따랐습니다.이 링크, 관련 드라이버를 설치하고 cp iwlwifi-2000-6.ucode /lib/firmware드라이버와 함께 제공되는 추가 정보 파일에 설명된 대로 실행하십시오.

시스템 설정에 나열된 내 사양은 다음과 같습니다.
