노트북의 무선 연결에 문제가 있습니다 Thinkpad X201. 설치했는데 CentOs 6.5 Minimal유선(케이블) 네트워크가 완벽하게 작동합니다. 하지만 무선은 감지되지 않습니다. 다음 링크를 보았지만 도움이되지 않았습니다.

를 통해 무선을 설정했는데도 실행 하면 ifconfig -a볼 수 없습니다 .wlan0NetWork ManagerGnome
아, 그런데 제 노트북에는 Windows7이 있는데, 깨끗하게 지우고 Linux를 설치했어요.

답변1
lspci -v 출력을 보면 "Intel Corporation Centrino Wireless-N 1000"이 무선 어댑터라고 가정합니다.
다음 페이지에 언급된 펌웨어가 도움이 되는지 확인해 주시겠습니까?

인텔® 센트리노® Wireless-N 1000 3.2+ iwlwifi-1000-ucode-39.31.5.1.tgz 2.6.30+ iwlwifi-1000-ucode-128.50.3.1.tgz
lsmod 출력에 iwlwifi 모듈이 설치되어 있는 것을 확인했습니다. 하지만 버전이 맞는지 확실하지 않습니다. 또한 커널이 2.6.30보다 오래된 경우 작동하지 않을 수도 있습니다.
