ThinkPad E580 装Ubuntu系 系统无WIFI 解决办法
首先得下载 最新的驱动，我之前因为自己的下载的驱动不够新，导致我的驱动一直装不上去
https://github.com/tomaspinho/rtl8821ce 这个是最新的驱动的下载 地址，建议从这里下载最新的 RTL 8821ce驱动
-
然后解压包，
-
修改Makefile文件
-
在当前的文件夹下面打开终端
相继输入
sudo make
sudo make install
sudo modprobe -a 8821ce
下面是终端完整的显示
pph@IBM:~/Downloads/rtl8821ce-master$ sudo make
请输入密码
[sudo] pph 的密码：
验证成功
