답변1
이는 버전을 찾고 유효한 버전을 찾아 로드할 때까지 로드하지 못하는 표준 deb 커널의 일반적인 현상입니다.
예를 들어 내 로그 파일에 있습니다.
10월 23일 16:39:43 mike-laptop4 커널: [7.432898] iwlwifi 0000:03:00.0: iwlwifi-7265D-24.ucode의 직접 펌웨어 로드가 오류 -2로 인해 실패했습니다. 10월 23일 16:39:43 mike -laptop4 커널: [7.432921] iwlwifi 0000:03:00.0: iwlwifi-7265D-23.ucode의 직접 펌웨어 로드가 오류 -2로 인해 실패했습니다.
(내 펌웨어 디렉토리에 iwlwifi-7265D-22.ucode가 있지만 23 또는 24는 없습니다)
따라서 어떤 이유로 Wi-Fi가 로드되지 않으면 올바른 펌웨어 버전을 찾을 수 없습니다.
펌웨어 다운로드를 위해 커널 Wi-Fi를 확인하는 것이 좋습니다.
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi
lspci를 실행하여 Wi-Fi 칩을 확인한 다음 커널 버전과 Wi-Fi 카드를 기반으로 적절한 펌웨어 Blob을 다운로드할 수 있습니다.
전원 관리에 대한 몇 가지 유용한 팁도 있습니다.
