我购买了联想 Ideapad 500S-14ISK 并安装了 Debian 8。这是全新安装，这台计算机上没有其他操作系统。
我在连接到 Wi-Fi 时遇到了困难，几天的谷歌搜索以寻找任何提示都没有任何好处。
我将在下面的命令上写下一些输出。
sudo iwconfig

安装所需的固件和向后移植将启用 Wi-Fi。
这些命令将在 Lenovo Ideapad 500S-14ISK 的 Debian 8 上完美运行。
首先安装一些基本工具（如果还没有的话）：
sudo apt-get install vim git build-essential
从 github获取固件并将所需的文件复制到系统文件夹中：
# 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
（我认为最后一行实际上不会改变任何东西，但我确信我不会搞砸任何事情）
下载反向移植，构建然后安装，然后重新启动。
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_pci 将在重新启动后开始运行，因此重新启动前的最后一行是不必要的？）
