ubuntu下安装rtl8811cu网卡

由于需要wifi调试，笔记本内置的网卡有点不太灵光，买了个TPLINK的WDN5200H AC网卡，给虚拟机用，折腾一下成功了

github上有rtl8821cu/rtl8811cu的驱动和安装方法，但是时间有点久了，新的内核计时器改变了很多，所以驱动已经过时，找到一个新的内核驱动，查看我的资源可以下载，github可以不用资源分下载驱动，如果看官愿意打赏一下我辛苦整理，那就下载一下我的资源吧 https://download.csdn.net/download/daxus/10801673

安装方法仍旧适用

How to do

Install driver

copy the whole repo to your PC, enter (your_dir)/rtl8821cu/, open a terminal and type:

make
sudo make install
sudo modprobe 8821cu

the driver installed.

Plug your USB-wifi-adapter into your PC

If wifi can be detected, congratulations. If not, maybe you need to switch your device usb mode by the following steps in terminal:

1. find your usb-wifi-adapter device ID, like "0bda:1a2b", by type:

lsusb

1. switch the mode by type: (the device ID must be yours.)

sudo usb_modeswitch -KW -v 0bda -p 1a2b

It should work.
