무선 네트워크 문제 해결 기록
이 노트북에 설치된 무선 모듈은 아래와 같다.
Network controller [0280]: Qualcomm Atheros Device [168c:0041] (rev 20)
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1436940 론치패드의 설명에 따르면 장치에 해당하는 드라이버는 우분투에서 동작하지 않는다는 보고가 있다. 168c:0041은 QCA6164라고 하고 ath10k라는 커널 모듈과 관련 있으나, 사용 중인 리눅스 민트 17.2에서는 modprobe로 오류 없이 실행은 되지만 무선 연결이 인식되지 않는다.
https://wikidevi.com/wiki/Ath10k 링크의 “Qualcomm Atheros QCNFA34AC“항목이 있고, 여기서 github 링크를 찾을 수 있다.
https://wireless.wiki.kernel.org/en/users/Drivers/ath10k Linux wireless 위키에도 비슷한 항목을 검색할 수 있었다.
