CentOS 7이 설치된 Intel NUC의 WiFi가 계속 끊어지는 이유를 알아내려고 합니다. 내가 아는 한, 나는 5개 노드 Hadoop 클러스터를 가지고 있고 모두 동일하게 구성되어 있지만(내가 아는 한) WiFi를 사용하는 다른 컴퓨터는 충돌하지 않습니다. 이 특정 기계에 어떤 문제가 있는지 모르겠습니다.
에서 발생하는 오류입니다 /var/log/messages. 며칠 동안 이 문제를 추적해왔기 때문에 저도 많이 보는 메시지입니다.

답변1
Wi-Fi 드라이버가 NUC의 Wi-Fi 하드웨어를 관리할 수 없는 것 같습니다.
여러 Linux 배포판을 설치 없이 직접 사용해 볼 수 있습니다. 내 생각에 NUC에는 Intel Wi-Fi가 있고 내장된 Linux 드라이버와 함께 작동해야 하지만 충분히 새로운 것이어야 합니다.
Intel 6세대 하드웨어가 탑재된 NUC가 있습니다. 이전 버전의 OS에서는 Wi-Fi 하드웨어를 관리할 수 없지만 최신 버전에서는 아무런 조정 없이 "즉시" Wi-Fi 하드웨어를 관리할 수 있다는 것을 알았습니다.
- 편집 1: NUC6i3SYH의 유무선 하드웨어를 모두 관리할 수 있는 라이브 시스템인 Ubuntu 18.04.1 LTS를 사용하여 테스트했습니다. Debian 9, Stretch는 유선 네트워크를 자동으로 관리할 수 있습니다. 내 Wi-Fi가 실패했지만 다른 사람이 고칠 수 있습니다. (드라이버 문제가 있는지, 아니면 데비안에서 Wi-Fi의 UI를 관리할 수 없는지 모르겠습니다.)
- 편집 2: 다운로드
CentOS-7-x86_64-LiveGNOME-1810.iso하여 실행했는데 NUC6i3SYH의 유선 및 무선 하드웨어를 관리합니다. Ubuntu 18.04.1 LTS만큼 쉽게 부팅됩니다. 하지만 오랫동안 안정성을 테스트하지 않았습니다.
편집 3: 하드웨어가 손상될 수 있다는 점을 고려해야 합니다(예: 뜨거워지면 오작동). 하지만 다른 운영체제에서도 잘 돌아가면 하드웨어가 좋다는 결론을 내릴 수 있다.
NUC 하드웨어는 언제 개발되었으며 CentOS 7 소프트웨어는 언제 개발되었습니까?
Centos 7에는 이전 커널 시리즈인 3.10이 있습니다. 시스템 "1810"의 현재 커널 버전은
3.10.0-957.el7.x86_64 #1 SMP.- 최신 Linux 커널과 최신 하드웨어 드라이버가 포함된 다른 운영 체제를 사용해 보십시오.
