电脑用一段时间以后，AirPort 自动关闭，无法再开启 :|

This topic created in 4896 days ago, the information mentioned may be changed or developed.

最近经常遇到这个问题，电脑了一段时间(时长不定)之后，网络突然中断，而AirPort那个扇形是满格的，下啦菜单显示的是“Turn AirPort Off”，wifi列表也都在，点击自家的wifi链接显示超时。

打开网络设置，这边状态已经显示”Status: Off“，旁边按钮也显示“Turn AirPort ON”。这时无论点击“Turn AirPort ON”还是前面的“Turn AirPort Off”，网络连接扇形都会变成空心，然后两边统一成“Turn AirPort On”了。

然而再次点击“Trun AirPort On”却一点响应也没有，console也没有这期间的日志信息：

13-1-11 下午03:23:22 GoogleSoftwareUpdateDaemon[13695] -[KeystoneDaemon main] GoogleSoftwareUpdateDaemon inactive, shutdown.
13-1-11 下午03:34:08 airportd[13824] Apple80211Associate() failed -3905 (Timeout)
（网络大概是3:33中断的，我在3:34尝试重连wifi，提示超时。接着又点了几次“Turn AirPort On”，没有日志。)

google没找到答案，只有系统重启才能恢复正常。

自娱自乐回复一下。以前没看到太多 airport 相关的 log，是因为它默认关闭，所以点击[Turn Airport On]似乎一点响应都没有。

# 09:21 网络问题再现，看起来跟电源管理有关：
