问题本身：有没有办法让这个指示灯根据无线状态打开和关闭（不仅仅是在有无线活动时闪烁）？
安装 Linux 后，我发现无线 LED 指示灯不工作。这个问题是在 Ubuntu 中出现的，但现在我使用 Debian（确实很棒！）。在 Elementary OS 0.2 Luna 中它运行良好，但在下一个版本 0.3 Freya 中这个问题再次出现。
我现在找到的唯一解决方案如下：
sudo rmmod -f ath9k
sudo modprobe ath9k blink=1
并创建了一个文件以避免每次启动系统时输入此文件：
sudo gedit /etc/modprobe.d/ath9k.conf
并在其中写入下一个字符串：
options ath9k blink=1
但它会眨眼，这很烦人！特别是当您有 2 个无线 LED 指示灯（一个与其他 3 个排成一排：电源、充电、硬盘）且第二个位于盖子背面时。 （这笔记本电脑型号：戴尔 Latitude 3340)

现在，dir 的遏制/sys/class/leds。有递归文件（链接），所以我将级别限制为3：
