我全新安装了 Ubuntu 14.04，这是我的新笔记本电脑 ASUS X550C 上第一个也是唯一的操作系统，但我无法连接任何 Wi-Fi，即使切换fn+ f2（键盘默认）也无法打开/显示 Wi-Fi 指示灯。
以下是我的系统的一些输出：

请尝试：
gksudo gedit /etc/modprobe.d/asus.conf
如果您没有文本编辑器 gedit，请使用 nano 或 kate 或 leafpad。添加一行：
options asus-nb-wmi wapf=0
仔细校对，保存并关闭文本编辑器。重新启动并告诉我们无线现在是否正常工作。如果没有，请再次编辑文件并将因子从 0 更改为 1，然后再次重新启动。您也可以尝试 4。
