통나무

Lenovo Ideapad 500S-14ISK를 구입하고 Debian 8을 설치했습니다. 새로 설치한 것이므로 이 컴퓨터에는 다른 운영 체제가 없습니다.

Wi-Fi 연결에 문제가 있어 며칠 동안 인터넷 검색을 통해 팁을 찾았지만 소용이 없었습니다.

답변1

필수 펌웨어를 설치하고 백포팅하면 Wi-Fi가 활성화됩니다.
이 명령은 Lenovo Ideapad 500S-14ISK의 Debian 8에서 완벽하게 실행됩니다.

몇 가지 기본 도구를 설치하여 시작하십시오(아직 설치하지 않은 경우).

sudo apt-get install vim git build-essential

펌웨어 받기github에서 필요한 파일을 시스템 폴더에 복사하세요.

# assuming that you use your Downloads folder to store the files needed.
cd ~/Downloads
git clone https://github.com/kvalo/ath10k-firmware.git
cd ath10k-firmware/QCA9377/hw1.0
sudo mkdir -p /lib/firmware/ath10k/QCA9377/hw1.0
sudo cp board.bin  /lib/firmware/ath10k/QCA9377/hw1.0
sudo cp firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin
sudo modprobe -r ath10k_pci

(마지막 줄이 실제로 아무것도 바꾸지 않을 것이라고 생각하지만 아무것도 망치지 않을 것이라고 확신합니다)

백포트 다운로드, 빌드한 다음 설치한 다음 재부팅합니다.

cd .. # getting back to the Downloads folder
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
tar -xf backports-20151120.tar.gz
cd backports-20151120
make defconfig-ath10k # pray for the make process here goes flawlessly.
make
sudo make install
sudo modprobe ath10k_pci
sudo reboot

(ath10k_pci는 재부팅 후 실행을 시작하므로 재부팅 전 마지막 줄은 불필요한 걸까요?)
