这个问题存在好久了,在苹果官方论坛上已经存在好长时间了,但苹果至今仍未修复此问题:
https://discussions.apple.com/thread/2142725
有人说在Network Preference -> Location 里,新添加配置,就可以了,但我没有尝试成功过。
我的版本是MBP 13 + Mac osx 10.8.5 ,从来不关机,在公司直接插网线,有时把本子的Wifi做为路由器使用,回家就直接用无线路由,不插网线。所以这个问题隔一段时间就回出现,一直没有找到解决方法,只能重新启动系统,否则就再也连接不了无线路由了,log日志如下:

最近回家后,又出现了这个问题,翻看log,看提示说是en1找不到station,en1对应的是Wifi,en0 对应的是网线口,会不会和在公司把本子当路由使有关呢,因为回家后,就从来没插过网线,这时候,就意味着Wifi的路由模式找不到en0,所以出现问题。
于是插上一根网线,和公司同样的场景,果不出所料,WiFi恢复正常。然后再拔掉网线,用Wifi连接家里的路由,Bingo!一切都正常了,终于可以不用重启系统了。
