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.
sudo modinfo /lib/modules/3.16.0-38-generic/kernel/drivers/net/wireless/ath/ath10k/ath10k_pci.ko filename: /lib/modules/3.16.0-38-generic/kernel/drivers/net/wireless/ath/ath10k/ath10k_pci.ko firmware: ath10k/QCA988X/hw2.0/board.bin firmware: ath10k/QCA988X/hw2.0/firmware-2.bin license: Dual BSD/GPL description: Driver support for Atheros QCA988X PCIe devices author: Qualcomm Atheros srcversion: 5D423944FD14FDF5261FFF8 alias: pci:v0000168Cd0000003Csv*sd*bc*sc*i* depends: ath10k_core intree: Y vermagic: 3.16.0-38-generic SMP mod_unload modversions signer: Magrathea: Glacier signing key sig_key: C2:84:ED:AC:CF:0B:47:36:52:C3:4D:23:BE:C3:56:94:42:36:E6:3B sig_hashalgo: sha512 parm: target_ps:Enable ath10k Target (SoC) PS option (uint) parm: irq_mode:0: auto, 1: legacy, 2: msi (default: 0) (uint) parm: reset_mode:0: auto, 1: warm only (default: 0) (uint)
그런데 이상하게도 ls로 보면
ls -l /lib/firmware/ath10k/QCA988X/hw2.0/ total 256 -rwxr-xr-x 1 root root 2116 5월 13 23:33 board.bin -rwxr-xr-x 1 root root 249093 5월 13 23:33 firmware.bin -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
위 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.
- https://github.com/kvalo/ath10k-firmware/archive/master.zip에서 파일을 받고 압축을 푼다.
/lib/firmware/ath10k/QCA6174디렉토리를 지우든지 다른 곳으로 이동한다.
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.
