2.驱动安装

这里以 Xubuntu16.04系统（内核：4.14）为例

下载地址：https://download.csdn.net/download/qq_45445740/88614252
下载后拷贝到目标设备上进行解压，运行 install-driver.sh 脚本

sudo ./install-driver.sh

在这里插入图片描述

待install-driver.sh安装完后可选择N，修改如下文件，将 /etc/modprobe.d/8812au.conf前面的 #号去掉，保存。
重启设备

3.查看无线网卡信息

此时可查看到插入的无线网卡信息

ifconfig

在这里插入图片描述

这里以 wlx08beac134a56 为例，查看可选择的信道

iwlist wlx08beac134a56 channel

在这里插入图片描述
