原理很简单，通过python执行dos命令 ： ping 和 netsh
需要用到os和time模块
代码如下：
>>> import os
>>> print ‘wifi掉线‘
wifi掉线
>>> import time
>>> while True:
... status = os.system("ping -c 1 www.baidu.com")
... if status == 1:
... print ‘wifi掉线‘
... os.system(‘netsh wlan connect name=DSGY2‘)
... else:
... print ‘连接状态‘
... time.sleep(180)
大家使用时将name=XX ,名字改一下，在我的机子上测试通过，该脚本3分钟检测一次是否掉线
如果你的wifi在手动连接都连不上，那这段脚本就没用了
