新买的神舟Z8-CU7NA：
身为码农，不得不安装ubuntu以便工作，但是安装之后，wifi竟然不能用：
这难道是网卡不识别，还是怎么回事，我们查看无线网卡类型
lspci |grep Network
结果看到：
RTL8821CE?
Google搜索，结果这个驱动需要自己安装，好在有人编译好了。
下载linux中8821CE/rtl8723de的驱动源码https://download.csdn.net/download/MrCharles/12774715
具体参考
https://github.com/tomaspinho/rtl8821ce
但是安装显示依赖问题！！！
安装之前，需要安装一些依赖
sudo apt install bc module-assistant build-essential dkms
sudo m-a prepare
charles@charles-hasee:~$ sudo m-a prepare

那还是要联网更新安装才行呀，怎么联网呢？看蓝牙是好的，那就手机蓝牙共享网络吧。打开设置里面的蓝牙，开启，连上手机，连上网络。
需要安装的是rtl8821ce-dkms_5.5.2.1-0ubuntu3_18.04.1_all.deb
联网之后更新apt-get
先别急安装，先安装dkms，
然后安装rtl8821ce-dkms_5.5.2.1-0ubuntu3_18.04.1_all.deb
charles@charles-hasee:/media/charles/Storage/software$ sudo dpkg -i rtl8821ce-dkms_5.5.2.1-0ubuntu3_18.04.1_all.deb
