Wireless light constantly blinking on Compaq Presario CQ60 laptop

[Nodaki]

The fix listed did not work on my HP 8510P.

root@xxxxxx:/sys/class/leds/mmc0::# ls /sys/class/leds/mmc0\:\:
brightness  device  max_brightness  power  subsystem  trigger  uevent

The rx and tx subdirectories do not exist.

Running this did not return errors but did not do anything either.

root@xxxxxx:/sys/class/leds# echo none > /sys/class/leds/mmc0::/trigger

Any other ideas?

None of the above solutions worked for me. My laptop is an HP nx9420 and i'm running Maverick (10.10).

The solution can be found here:

Run in terminal:

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

Add the line:

options iwlcore led_mode=1

Just reboot and that's it. Works flawlessly.

I've switched back to the ath5k driver for better support. I'll go through the fix for anyone having difficulty:

First of all you will need to be root to run these commands so open up a terminal window and type:

sudo -s

Type in your password to drop to root@ubuntu.

First off all you will need to find if your system is using the Atheros 5k or 9k driver. So you can run the following commands in the terminal we've opened to find out:

echo none > /sys/class/leds/ath9k-phy0\:\:rx/trigger
echo none > /sys/class/leds/ath5k-phy0\:\:tx/trigger

For Compaq CQ60's the driver is ath5k however executing both of these commands, you will find one will execute with no errors and one will execute with the directory not found error. Whatever one executes silently is the ath driver in use. In my case, the ath5k driver.

Upon executing the command that is relative to your ath driver you should find the wireless light changes and now doesn't blink when network activity is occurring.

However, the change we have done will not be saved permanently, we have to create a script to make sure the wireless light doesn't blink on each reboot of the machine.

Run the following command in terminal:

gedit /etc/network/if-up.d/wlan-no-blink

And now add the following into the blank text file:

#!/bin/sh
if [ "$IFACE" = "wlan0" ]; then
    for dir in /sys/class/leds/ath5k-phy*x; do
        echo none > $dir/trigger
    done
fi

This example is for the ath5k driver, if you are using the ath9k driver, make sure you change number 5 to 9

Now you have the script, save and close gedit. Now in the terminal window, run the following command:

chmod a+x /etc/network/if-up.d/wlan-no-blink

Now upon each reboot your wireless light change will be saved.

Thanks again Iron_maiden_forever for posting the fix and gonzalioz, hopefully I've helped you understand the process a bit better.

I had the same problem, after a clean install with Windows 7. The above worked. after installing 10.04 twice, the first time my nvidia drivers did not wrk properly, everything now works flawlessly. Anyways thx for the solution.

I have the presario cq-61-420 (amd athlon/ati) with the atheros wlan and it seems to blink during data Xfr, and goes blue at idle at various hot-spots. At home, it seems to continually alternate (works fine otherwise)- so may differ with router configs or # clients using it.
I think I'll leave it alone since it clues me as to data xfr which can be erratic at some places.
These forums ARE a big plus- thanx to everyone.

I had a second fresh installation on my HP 6530b with Ubuntu 10.10 and this flashing BLUE / Orange LED was driving me crazy as well. jeez.

OK, HOW I FIXED IT ... just turned the bluetooth ON from the icon next to the wifi icon , lol . how lame.

I went trough 5 min registration process just to share that, I must be loco.

This has just worked on my Compaq Presario CQ70. Thanks so much! The wireless light has always flickered orange and blue but not any more.

This was the clue I needed for my HP 8510p. The wireless module name is now iwl_legacy, so my /etc/modprobe.d/wlan.conf contains :

# 1 means don't blink
options iwl_legacy led_mode=1
