我的笔记本电脑 wifi LED 不工作

我正在使用 Ubuntu 12.10 X64，我的笔记本电脑是 Asus X32U。WIFI 连接工作正常，但笔记本电脑上的 WIFI LED 根本不工作。这是rfkill 列表结果

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: asus-wlan: Wireless LAN
Soft blocked: no
Hard blocked: no

有人能帮助我吗？

答案1

请尝试临时驱动程序参数：

sudo modprobe -r ath9k
sudo modprobe ath9k blink=1

如果它按预期工作，请使其持久化：

gksudo gedit /etc/modprobe.d/ath9k.conf

添加一行：

options ath9k blink=1

校对、保存并关闭 gedit。一切就绪。

答案2

这不适用于我的华硕 K46 笔记本电脑，所以我尝试进行挖掘。

找到参数 blink 和 led_active_high 后，我对它们进行了如下测试（当然使用sudo su）：

modprobe -v -r ath9k
rmmod ath9k
rmmod mac80211
rmmod ath9k_common
rmmod ath9k_hw
rmmod ath
rmmod cfg80211

modprobe -v ath9k blink=1
insmod /lib/modules/4.15.0-15-generic/kernel/net/wireless/cfg80211.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/net/mac80211/mac80211.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/drivers/net/wireless/ath/ath.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k_hw.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k_common.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k.ko blink=1

modprobe -v -r ath9k
rmmod ath9k
rmmod mac80211
rmmod ath9k_common
rmmod ath9k_hw
rmmod ath
rmmod cfg80211

modprobe -v ath9k led_active_high=1
insmod /lib/modules/4.15.0-15-generic/kernel/net/wireless/cfg80211.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/net/mac80211/mac80211.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/drivers/net/wireless/ath/ath.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k_hw.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k_common.ko 
insmod /lib/modules/4.15.0-15-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k.ko led_active_high=1

..并且 wifi LED 仍然熄灭（但奇怪的是在其他操作系统上可以工作）。
