我的 wifi Qualcomm Atheros 设备 [168c:0041](rev 20)在联想 flex 3 14 上的 Ubuntu 14.04.3 中无法显示和工作

我是 Linux 系统新手,我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,你只需要安装固件并使用以下方式设置参数

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,你需要反向移植和固件


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有问题dmesg | egrep -i 'ath|firm

编辑以添加: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

如果你获得了一个新内核,你的无线将停止工作,直到新内核包含修复,如果你注意到 wifi 在重启后无法工作

cd backports-4.4.2-1
make clean
make defconfig-ath10k
make
sudo make install

重启

使用 Lenovo u31-70 笔记本电脑测试运行内核 4.3.0-7-generic 的 Ubuntu Xenial Xerus (LTS,开发分支) 28.1.2016 预发布版。包含对“Qualcomm Atheros Device [168c:0041] (rev 20)”的 Ath10k 驱动程序支持,但目前缺少固件。请注意,安装上述内容deb将不起作用,因为模块已在内核中

git clone https://github.com/atondwal/ath10k-firmware.git
sudo cp -r ath10k-firmware/ath10k/QCA6164 /lib/firmware/ath10k
cd /lib/firmware/ath10k/QCA6164
## Also this module option is needed
echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf
# Reboot... or mess with module loading
