Wireless LED not working on Asus K53E laptop with ath9k driver

Hi fellow Archlings,
After searching via Google and the Arch Forums for the past six hours, I've still yet to see the indicator LED light blink at all.  All of my laptop's other five LEDs work (power/sleep, battery, hard disk activity, num lock, caps lock), but from boot till my wifi is connected to a network and thereafter the LED stays dark.  This issue isn't big, just a minor trouble.
Kernel:
# uname -r
3.1.5-1-ARCH
http://ubuntuforums.org//showthread.php?t=1879706
I eventually stumbled on the above thread from the Ubuntu forums which gave good advice, including the modinfo command, which I was using with
# modinfo -F parm ath9k
btcoex_enable:Enable wifi-BT coexistence
blink:Enable LED blink on activity
nohwcrypt:Disable hardware encryption
debug:Debugging mask
However running
# modprobe -r ath9k
# modprobe ath9k blink=1
doesn't make any change to the LED - still pitch black in there (well, there's the ambient light from peripheral buttons but you know... ).
I've been to
# cat /sys/class/leds/ath9k-phy0/trigger
none AC0-online BAT0-charging-or-full BAT0-charging BAT0-full BAT0-charging-blink-full-solid rfkill1 rfkill3 phy0rx phy0tx phy0assoc phy0radio [phy0tpt]
# echo X > /sys/class/leds/ath9k-phy0/trigger
where X includes all of the possible values listed by the cat command, individually of course.
Does anyone have any insight into what the issue may be or what I ought to try next?  Thanks all.

Hmm... I also found this:
http://ubuntuforums.org/showpost.php?p= … ostcount=6
I'm wondering where I would put the following script in the Arch filesystem - any direction would be most appreciated!
#!/bin/sh
if [ "$IFACE" = "wlan0" ]; then
for direc in /sys/class/leds/ath9k-phy0::rx
do
echo none > $direc/trigger
# never trigger blinking for RX
done
for direc in /sys/class/leds/ath9k-phy0::radio
do
echo none > $direc/trigger
# never trigger blinking for radio
done
for direc in /sys/class/leds/ath9k-phy0::assoc
do
echo phy0assoc > $direc/trigger
# do trigger blinking during association
done
for direc in /sys/class/leds/ath9k-phy0::tx
do
echo phy0assoc > $direc/trigger
# never trigger blinking for TX
done
fi
In Ubuntu the script is placed in /etc/network/if-up.d/ but where is that to be found in Arch Linux, and will it work with NetworkManager instead of the regular network daemon?
EDIT: Okay, so I just tried placing the following script in /etc/NetworkManager/dispatcher.d/ and making it executable - still no luck after reloading the module:
#!/bin/sh
INTERFACE=$IFACE
if [ "$IFACE" = "wlan0" ]; then
for direc in /sys/class/leds/ath9k-phy0::rx
do
echo none > $direc/trigger
# never trigger blinking for RX
done
for direc in /sys/class/leds/ath9k-phy0::radio
do
echo none > $direc/trigger
# never trigger blinking for radio
done
for direc in /sys/class/leds/ath9k-phy0::assoc
do
echo phy0assoc > $direc/trigger
# do trigger blinking during association
done
for direc in /sys/class/leds/ath9k-phy0::tx
do
echo phy0assoc > $direc/trigger
# never trigger blinking for TX
done
fi

  • Satellite L750/05q - Wireless LED not working

    Have an L750/05q running Win 7 64bit.
    Wireless works fine but the Wifi led not lighting up when wireless activated, only the bluetooth indicator led comes on when Bluetooth on, Wifi on or both on.
    Updated from toshiba site to latest Toshiba listed Atherios driver - 9.2.0.316 (my model is not listed on their AU support site), but still no led. Wireless works fine.
    Also updated the LAN driver (Realtek) too,
    Am wondering if this is just a failure in hardware rather than the driver.
    Any ideas? Thanks.

    Thanks Akuma and MisterX. On reading your replies I went back and read the manual more 'carefully'; I had interpreted wireless WAN as internet but it most likely refers to a GPS card function which is not installed in this model. Thanks for taking the time to reply and put my mind at ease.
    Cheers :)

  • [nForce] msi k7n2delta ilsr hdd led not work

    hi guys, well there is not much to say only that my hdd led not work, rarely i put attention on it, but just when i see... is gone... sniiiff.. i tryed change the led, invert cables, and the raid controller has nothing to do with this issue, sometime ago i have power issues, and during those times the led suddenly "wake up" , then i change the psu, and hdd, now i have sata hdd, and somebody told me the led not work with the 3· ide or sata, culd be the data cable
    thanks

    "...yes yes i know that, right now using sata i know the hdd led not work, but when i-m using ide drive either, thas wy i saying may be the ide cable.thanks..." That's not what you said in your first post. IF IDE HDD works (even if HDD led doesn't work) then IDE cable should be OK. Perhaps HDD light case/mobo connection has a problem.

  • Keyboard wireless key not working after upgrading to windows 8.1

    Hello,
    I am having hp pavilion dv6-6165tx notebook, where keyboard having a wireless button that turns ON and OFF all wireless devices, After upgrading to windows 8.1, HP Connection Manager is not getting installed, as well as Key is not working, key color turns red and white but no action is performed.
    Kindly suggest me some solution.
    Note: HP Doesn't provide drivers for windows 8/8.1 ONLY WINDOWS 7 for hp pavilion dv6-6165tx.
    Thanks.

    Hi @Jayesh_Bhadja ,
    Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv6-6165tx Notebook and the Wireless keyboard not working correctly. Here is a link to troubleshoot the keyboard.
    The HP Connection Manager is something that is for Windows 7 not Windows 8.1. I would uninstall this from your Notebook.  Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system that need updating. It has a troubleshooting tool in this.
    Make sure all your updates have been completed. I would try restarting my Notebook a few times.
    If that does not help I would uninstall the keyboard from the Device manager.
    Thanks.

  • HP 5524 Wireless does not work after firmware upgrade

    HI,
    I have just purchased an HP5524.  After initial problems setting up the WPA key from the printer screen, I connected via USB, found the printer and swapped to wireless successfuly. I then installed the printer software on all my computers at home successfully over wireless.
    The printer then needed a firmware upgrade to support eprint (?), which is successfully connected, downloaded the fireware, installed and went through the boot cycles successfully. 
    However, ever since wireless will not work.  Before I return it to the retailer as "not fit for purpose" I thought I would ask the forum.  The diagnostics downloaded a tool, which I went through, but this did not offer solutions that I had not already tried.
    Thank you

    Hi,
    Thank you for posting you query,
    In order to resolve the issue, please make sure the printer is placed closer to the router and uninstall the printer drivers already installed and then start the instalaltion and seelct teh connection type as wireless network. Then select use USB to configure wireless and when prompted conenct the USB cable and then select the network and enter the encryption key follow the onscreen  instructions.
    If the issue still persisits, please open the browser and in the address bar enter the IP address of the router and click on GO. This will take you to the router configuration page. On the router page, please click on Wireless Setup  and please make sure SSID Broadcast is enabeld and the Wireless Mode is set to Mixed or 802.11 B/G/N and the Wireless Channel is set to 11 and click on Apply. Then try to connect the printer to the network by using the CD.

  • Dv6 power led not working

    Hi everybody!
    Today, I changed the fan in my Pavilion dv6-6001eh (the original stop working). After I assembly, the power led not working anymore. I check the cable, but that's ok. Otherwise the power button working. The second power led in the right side next to USB, also not working.
    Why? Maybe pressed hotkey?
    Thank you.

    Any advice?

  • Tecra A3 - Creative Mouse Wireless does not work

    Does anyone know how to solve this problem?
    Thank you,

    Hello
    On this way it is not easy to say what the problem is. I assume that you got some installations software for your external device. Install it and it should works.
    As far as I know functionality of external mouse doesn`t depend on touchpad settings.

  • HP FQ834UT USB Universal Docking Station software won't work on my HP laptop with Windows 7 64 bit

    I am using Windows 7 and when i went to load software for my docking station, HP FQ834UT USB Universal Docking Station, it said it couldn't use the driver.   Is there a software upgrade to allow this driver to work on a HP laptop with Windows 7 64 bit operating system?   

    I have the same issue - I have it installed on my Windows 7 64-bit machine and although it is running, it doesn't work.  I am sitting here in Starbucks, which has a Verizon Wifi hotspot (actually Boingo - which is what Verizon Wi-Fi uses) and the "Connect" box does not appear.  I had the same issue at an airport recently.  It's one of the worse pieces of software I have had the misfortune to use.  When it fails to connect, it causes the Wifi connection to drop (incompatibility with Lenovo Access Connections, maybe).  I don't think that Verizon understands the meaning of "QA" and "Software Testing".
