校园网无线AP自动开网口脚本

0.background

最初是可以手动打开每个宿舍无线接入点的有线网口的

参考校园网无线接入点修改教程

然鹅无线接入点现在每隔一段时间就会编译新固件关闭网口

具体脚本代码可以跳转GitHub

说明：

  • 需要按照之前教程：连接调试线后断电重启无线接入点才能让系统建立识别
  • 所以如果电脑关机是需要重新断电了（如果你是计算机专业没有关电脑习惯那么挺合适
  • 后期会寻找ARM等低功耗设备进行24小时连接检测（正在研究用树莓派、香橙派等Linux的串口操作

1.硬件准备

Usb-rj45调试线（上一个教程有说明

windows 10电脑

2.运行环境

Windows 10（其实win就可

Python 3+
Python安装好相应的包：import serial
