Debian Wheezy에 무선 네트워크가 표시되지 않음

이것이 계속이다다른 게시물이제 해결되었습니다.

이제 실제로 사용 가능한 무선 네트워크 목록을 얻으려고 합니다. Intel 7260이 올바르게 설치 및 감지되는 것으로 보이지만 "mar"라는 ESSID를 포함하려는 시도는 실패합니다. 나는 사용해 보았습니다 wpa_supplicant(문제 설명에서 자세한 내용을 참조하십시오).

사용된 네트워크 목록을 얻을 수 있지만 iwlist scan사용 결과는 없습니다 wpa_cli list_networks(자세한 내용 참조). 이것은 나에게 모두 새로운 것이기 때문에 나에게 큰 의미가 없습니다.

그런데 가장 놀라운 점은 iwlist scan네트워크 목록이 제공된다는 점이죠?

list_networks그런데 왜 결과가 나오지 않는지 아직도 잘 모르겠습니다 (?). 사용법을 잘못 이해한 것 같습니다.
