我的wifi高通Atheros设备（转20）没有出现在联想flex 3 14上的Ubuntu 14.04.3中工作
我是Linux系统的新手我已经尝试了一些相关的解决方案，我可以跟进，但还没有。请帮我解决这个问题。

对于Ubuntu 16.04用户：不要使用dkms或backports，只需要安装固件并使用设置参数
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb sudo dpkg -i linux-firmware_1.158_all.deb
重启
对于Ubuntu 14.04和15.10，您需要后端端口和固件
wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.4.2/backports-4.4.2-1.tar.gz sudo apt-get install build-essential linux-headers-generic tar -zxvf backports-4.4.2-1.tar.gz cd backports-4.4.2-1 make defconfig-wifi make sudo make install
重新启动并查看固件是否存在dmesg | egrep -i 'ath|firm问题 dmesg | egrep -i 'ath|firm
编辑添加： 固件安装
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb sudo dpkg -i linux-firmware_1.158_all.deb
固件安装结束
如果你得到一个新内核，你的无线将退出工作，直到新内核包含修复程序，如果你注意到重启后无法使用wifi
cd backports-4.4.2-1 make clean make defconfig-ath10k make sudo make install
重启
测试预发布的Ubuntu Xenial Xerus（LTS，开发分支）28.1.2016运行内核4.3.0-7-通用联想u31-70笔记本电脑。 Ath10k驱动程序支持“Qualcomm Atheros Device [168c：0041]（rev 20）”，但目前缺少固件。 请注意，安装上面的deb不起作用，因为模块已经在内核中
