우리 회사는 Digital Guardian의 제품 요구 사항 때문에 특정 커널로 다운그레이드하도록 강요합니다(원칙은 변경할 수 없음). 내 경우에는 6.2.0-32-일반에서 5.19.0-45-일반까지입니다. Lenovo P53(우분투 인증)의 이전 커널을 사용하면 Wi-Fi 모듈이 작동하지 않습니다. 누군가 누락된 내용을 찾는 방법("작동하는" 커널에서 부팅하는 동안)과 이전 커널에서도 작동하게 만드는 방법을 추천할 수 있습니까?
참고: 최신 커널로 다시 재부팅하면 모든 것이 다시 작동합니다.

답변1
죄송합니다. 저는 이 패키지에 대해 잘 모릅니다. 나에게 도움이 된 것은
sudo apt-get install linux-modules-extra-5.19.0-45-generic
저는 이 패키지를 몰랐습니다. 이 스레드에 언급된 backport-iwlwifi-dkms를 제거하지 않았으며 여전히 작동하므로 그대로 유지하겠습니다.
