联想thinkpad E470c，无线网卡是 Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC

Worked solution (Requirements: kernel >=4.11) :

Download driver directory from this repo: https://github.com/endlessm/linux/tree/ ... /rtl8821ce

You can do it by this link: https://minhaskamal.github.io/DownGit/# ... /rtl8821ce

Unpack zip archive.
Change the Makefile. Line "export TopDIR ?= ..." to export "TopDIR ?= PATH TO EXTRACTED DIRECTORY".
make
sudo make install
sudo modprobe -a 8821ce
要求内核高于4.11,ubuntu16内核最高好像是4.10，需要自己升级内核版本
两个链接是linux内核链接和下载链接
Makefile文件中把 "export TopDIR ?= ..." to export "TopDIR ?= PATH TO EXTRACTED DIRECTORY" 就是填写当前路径地址
最后一步可能说没有钥匙什么的，需要关闭BIOS中的Secure Boot。关闭之后就OK

1.查看内核 uname -a
2.sudo apt-get update (这一步更新包列表)
3.sudo apt-get dist-upgrade (这一步安装所有可用更新，包括新内核)
