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
- 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
- 这里以
wlx08beac134a56
为例,查看可选择的信道
iwlist wlx08beac134a56 channel
- 查看无线网卡的详细信息
