Worked solution (Requirements: kernel >=4.11) :

Download driver directory from this repo:https://github.com/endlessm/linux/tr...less/rtl8821ce. You can do it by this link: https://minhaskamal.github.io/DownGi...less/rtl8821ce
Unpack zip archive.
Change the Makefile. Line "export TopDIR ?= ..." to export "TopDIR ?= PATH TO EXTRACTED DIRECTORY".
make
sudo make install
sudo modprobe

 

内核版本大于4.16(also said >=4.14)；

WiFi更换名称之后需要重启才能连接；

只是内核里还没有更新驱动而已。
直接把驱动源码编译到内核，加载驱动模块就行了。

 

使用链接6中的方法并没有好使；

sudo apt-get update && sudo apt-get install

or

sudo apt-get install dkms git
sudo git clone https://github.com/gnab/rtl8812au.git
sudo dkms add ./rtl8812au
sudo dkms install 8812au/4.2.2
