Qualcomm atheros QCA61x4a不被识别

Question

我有一个联想Y720与高通Atheros QCA61x4A，自从我开始使用Linux (我是一个初学者)，我一直无法与我的家庭wifi连接。Ubuntu18.04不认识这个设备。

我怎么才能解决这个问题？

检查mokutil --sb-state是否显示启用了安全引导，在BIOS设置中禁用安全启动，然后在终端执行

sudo apt install git dkms build-essential
git clone https://github.com/jeremyb31/ideapad-laptop.git
sudo dkms add ./ideapad-laptop
sudo dkms install ideapad-laptop/1.0

重新启动
