使用一下命令查看无线网卡的版本：

sudo lshw -C network

其中product输出网卡的类型，到GitHub上查询QCA6174 ，找到编程语言为Shell的包（不要下载c以及其他的），复制到ubuntu中，安装驱动：

sudo su ./ath10k-firmware-fixer.sh

提供网络驱动程序的软件包是 linux-modules-extra。由于不明白的原因，它没有安装在更新中。查看ubuntu内核版本：

uname -r

在ubuntu官网中（下载地址）下载对应的包，将其下载到其他计算机上，并使用 USB 密钥或类似设备进行传输。将其拖放到 Ubuntu 计算机的桌面上。现在，在终端中：

cd ~/Desktop
sudo dpkg -i linux*.deb
sudo reboot
