无法识别 Qualcomm atheros QCA61x4a

我有一台搭载 Qualcomm Atheros QCA61x4A 的联想 Y720，自从我开始使用 Linux（我是初学者）以来，我一直无法连接到我家的 wifi。Ubuntu 18.04 无法识别该设备。

我怎样才能解决这个问题？

检查mokutil --sb-state是否显示安全启动已启用，重新启动并在 BIOS 设置中禁用安全启动，然后在终端中执行 

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

重启
