macosx是什么意思，解決Mac osx AirPort: Link Down on en1. Reason 8 (Disassociated because

這個問題存在好久了，在蘋果官方論壇上已經存在好長時間了，但蘋果至今仍未修復此問題：

有人說在Network Preference -> Location 里，新添加配置，就可以了，但我沒有嘗試成功過。

macosx是什么意思？我的版本是MBP 13 + Mac osx 10.8.5 ，從來不關機，在公司直接插網線，有時把本子的Wifi做為路由器使用，回家就直接用無線路由，不插網線。所以這個問題隔一段時間就回出現，一直沒有找到解決方法，只能重新啟動系統，否則就再也連接不了無線路由了，log日志如下：

最近回家后，又出現了這個問題，翻看log，看提示說是en1找不到station，en1對應的是Wifi，en0 對應的是網線口，會不會和在公司把本子當路由使有關呢，因為回家后，就從來沒插過網線，這時候，就意味著Wifi的路由模式找不到en0，所以出現問題。

于是插上一根網線，和公司同樣的場景，果不出所料，WiFi恢復正常。然后再拔掉網線，用Wifi連接家里的路由，Bingo！一切都正常了，終于可以不用重啟系統了。
