我使用的是 xubuntu 14.10，我的 wifi 总是随机断开连接。浏览大约 1 小时后，我的互联网连接将不再起作用，但是 wifi 仍然连接着。如果我断开 wifi 连接并重新连接，连接就会正常工作。似乎在我使用的任何其他设备上都没有发生这种情况（Android 平板电脑 Nexus 7、OS X）
wireless_script下面是我使用得到的结果：wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script
结果可以在 pastebin 上找到：http://pastebin.com/uwJjz0KP
这是崩溃之前的同一个文件：http://pastebin.com/uu5pmPcs
它们最后似乎有一个重要的区别：

知道为什么会发生这种情况以及如何解决它吗？
