이 문제를 해결하는 방법을 모르겠습니다. 이 문제를 해결하려면 어떤 조치를 취해야 합니까?
답변1
대부분의 사람들에게 이 문제는 일시 중지/최대 절전 모드 후에 발생하는 것 같습니까? 아직 명확한 답을 찾지 못했지만 다음을 통해 더 가까워질 수 있습니다.
비슷한 것 같기도 합니다.
/etc/pm/sleep.d/일시 중지했다가 다시 시작하면 무선 카드 작동이 중지되므로 모듈을 제거한 wl다음 다시 로드 하는 작은 스크립트를 작성해야 합니다 . 이것이 어떤 식으로든 도움이 되기를 바랍니다!

분명히 당신이 사용하고 있는 "wl" 드라이버는 이런 무작위 오류를 일으키기 쉽습니다. "wl" 드라이버를 제거하고 Broadcom에서 다운로드한 드라이버를 직접 설치하여 문제를 해결한 동일한 Broadcom 브랜드의 다른 사람을 찾았습니다. (프랑스어 페이지, 영어로 번역됨)
행운을 빌며 이것이 효과가 있는지 알려 주시기 바랍니다.

전원 관리에 문제가 있을 수 있습니다. 질문에서 참조한 Wiki에 제공된 솔루션을 시도해 보셨나요 iwconfig wlan0 power off?
