电脑上装了个Fearoa，有没有网线，于是买个了便宜的无线网卡。

然后呢，客服说不支持Linux，然而他的网站上是有这个驱动的，但是编译总是出错。于是去万能的GITHUB上寻找答案。。

就是这个网卡:

 

步骤如下：

1：安装支持文件

sudo dnf install git dkms kernet-devel-$(uname -r)  kernet-debug-devel-$(uname -r)

2：下载驱动芯片驱动(这个无线网卡的芯片型号是RTL 8812BU)

        PS:如果不知芯片型号，插到WINDOW系统上看看属性

 git clone https://github.com/morrownr/88x2bu-20210702.git

3: 进入编译

cd 88x2bu-20210702
sudo sh ./install-driver.sh

4.重启，配置连接无线网即可

如果没有GUI界面配置，则配置文件路径在：

# /etc/NetworkManager/system-connections[mc@fedora system-connections]$ sudo cat TL_5G.nmconnection 
[connection]
id=TL_5G
uuid=12d94091-9392-4af6-2967-bdc8f183e041
type=wifi
interface-name=wlan1[wifi]
mode=infrastructure
ssid=TL_5G[wifi-security]
auth-alg=open
key-mgmt=wpa-psk
psk=12345678[ipv4]
method=auto[ipv6]
addr-gen-mode=stable-privacy
method=auto[proxy]

5: 重启，上网
