我的笔记本电脑使用的是 Debian 8.5，但 wifi 无法使用。我已经格式化四次了，还是出现同样的错误。
我已经安装了 realtek 固件，但无法解决此问题。这是lspci的结果

答案1
您需要安装固件-atheros从向后移植：
此软件包包含 ar5523、ath3k、ath6kl_sdio、ath6kl_usb、ath9k_htc 或支持的 USB 无线网络和蓝牙卡的二进制固件th10k司机。
编辑您的sources.list：
nano /etc/apt/sources.list
添加以下行：
deb http://ftp.debian.org/debian jessie-backports main
保存并安装所需的包：
apt-get update
apt-get -t jessie-backports install firmware-atheros
modprobe ath10k_pci
编辑
使用稳定版本的常规存储库，不ath10k包含在firmware-atheros包中：
此软件包包含 ar5523、ar9170、ath3k、ath6kl_sdio、ath6kl_usb 或 ath9k_htc 驱动程序支持的 USB 无线网络和蓝牙卡的二进制固件
下载向后移植然后编译ath10k：
sudo apt-get install build-essential
sudo apt-get install linux-headers-$(uname -r)
wget http://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.2.6/backports-4.2.6-1.tar.xz
unxz backports-4.2.6-1.tar.xz
tar xvf backports-4.2.6-1.tar.gz
cd backports-4.2.6-1
make defconfig-ath10k
make
sudo make install
编辑
您的网卡是：QCA6174 802.11ac 无线网络适配器
运行以下命令：
git clone https://github.com/kvalo/ath10k-firmware.git
cp -r ath10k-firmware/QCA6174 /lib/firmware/ath10k/
cp /lib/firmware/ath10k/QCA6174/hw2.1/firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 /lib/firmware/ath10k/QCA6174/hw2.1/firmware-5.bin
重启然后运行modprobe ath10k_pci
