Python wifi掉线重连接

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

昨天没有把代码保存，也没有碰到掉线的情况

#-*-coding:utf-8-*-
import os
import time
while True:
    status = os.system('ping -c 1 www.baidu.com')
    if status == 1:
        print u'wifi掉线'
        os.system('netsh wlan connect name=haha')
    else:
        print u'连接状态'
    time.sleep(30)

运行情况
