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.

드라이버 설치 요령에 대한 포럼도 검색되었다: http://askubuntu.com/questions/607707/ath10k-installation

리눅스 민트 설치 후 아무런 변경을 하지 않은 상태에서 다음 명령을 수행햐 봤다.

그런데 이상하게도 ls로 보면

ls -l /lib/firmware/ath10k/QCA988X/hw2.0/
total 256

-rwxr-xr-x 1 root root   5402  5월 13 23:33 otp.bin

firmware-2.bin 이라는 파일이 안 보인다. 이게 뭐지?

첫번째로는 https://github.com/kvalo/ath10k-firmware 이 사이트에서 받은 firmware를 firmware-2.bin으로 복사하는 방법을 취해 보았다. 이 쪽의 문서를 참고하였고.

$ sudo rmmod ath10k_pci
$ sudo rmmod ath10k_core
$ sudo modprobe -v ath10k_pci
sudo modprobe -v ath10k_pci
insmod /lib/modules/3.16.0-38-generic/kernel/drivers/net/wireless/ath/ath10k/ath10k_core.ko 
insmod /lib/modules/3.16.0-38-generic/kernel/drivers/net/wireless/ath/ath10k/ath10k_pci.ko

실패. 그렇다면 혹시 펌웨어를 완전히 변경하면?

무선랜 동작시키기

론치패드 링크에서 'Diego'라는 사람이 쓴 코멘트를 통해 무선랜을 동작하게 만들 수 있었다. 코멘트 28번을 참고하자. 34번 코멘트에 부가적으로 설명이 되어 있으니 이것도 참고하라.

리눅스 민트 18(Ubuntu 16.04)에 와서는 커널 4.4로 업그레이드 되어 이 모델의 와이파이가 지원된다. 그러나 펌웨어 때문에 와이파이가 도작하지 않는 것으로 보인다. 같은 페이지에 새로운 해설이 실렸다 다음과 같이 하면 된다.

sudo cp -r ath10k-firmware-master/QCA6174/ /lib/firmware/ath10k/
cd /lib/firmware/ath10k/QCA6174/hw2.1/

# firmware-5, firmware-4 이름 변경
sudo mv firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 firmware-5.bin
cd /lib/firmware/ath10k/QCA6174/hw3.0/
sudo mv firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1 firmware-4.bin

블루투스 동작시키기

무선랜은 동작했지만 칩셋은 아직 블루투스 디바이스를 제대로 인식하지 못한다.

리눅스 민트 18(Ubuntu 16.04)에서 블루투스 인식을 올바르게 한다.
