Blinking wifi LED

[mobusby]

This fix is working on 10.04 RC (Lucid RC) with the following script:

#!/bin/sh

if [ "$IFACE" = "wlan0" ]; then
	for direc in /sys/class/leds/iwl-phy*X
	do
		echo none > $direc/trigger
		# never trigger blinking for TX, RX
	done
	
	for direc in /sys/class/leds/iwl-phy*radio
	do
		echo none > $direc/trigger
		# never trigger blinking for radio
	done

	for direc in /sys/class/leds/iwl-phy0*assoc
	do
		echo phy0assoc > $direc/trigger
		# do trigger blinking during association
	done
fi

As before, create the script in /etc/network/if-up.d/ (call it whatever you want, I named the script "iwl-no-blink").

sudo gedit /etc/network/if-up.d/iwl-no-blink

And give it the proper ownership and access rights

sudo chown root /etc/network/if-up.d/iwl-no-blink
sudo chmod a+x /etc/network/if-up.d/iwl-no-blink

mobusby, your script worked for me after I made a few modifications. I just needed to change the directories.

#!/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

Now my light only blinks when connecting to a network.
Thank you.

Works great. Thanks a lot

no more love on 10.10.... i have tried the three fixes but they no longer work for me on 10.10


thanks in advance

[spez]

yes I confirm this script is not working on 10.10
can anybody tell us how to fix?

[jac_tict]

Yes, not working on 10.10
No /sys/class/leds/iwl-phy* anymore.

I got this nailed in 10.10 -- to disable the blinking, you have to add the following line to /etc/modprobe/*iwlagn*.conf (there should only be one file in there, on my HP EliteBook 8530w its /etc/modprobe.d/intel-5300-iwlagn-disable11n.conf)

options iwlcore led_mode=1


...once I did that, I simply did a `rmmod iwlagn` and `modprobe iwlagn`, and my blinking stopped!!!

w000t!

options iwlcore led_mode=1

For the record, I figured that out by using `systool` a la:

# lsmod | grep -i iwl
iwlagn                202721  0 
iwlcore               146875  1 iwlagn
mac80211              266657  2 iwlagn,iwlcore
cfg80211              170293  3 iwlagn,iwlcore,mac80211
# systool -m iwlagn -av | grep led
# systool -m iwlcore -av | grep led
    led_mode = "0"
#

EUREKA!

I knew all I had to do was flip the bit...

Thanks for that... I might be being a bit thick, but what is a rmmod and modprobe and how do I do it - I'm a bit new! I have put the line in the right file already and saved it.

thanks!

Sure! So, from a shell:

# vi /etc/modprobe.d/iwl*
<make your change>
# rmmod iwlagn
# modprobe iwlagn

Those are the commands you use to manage/mangle the loadable kernel modules. You'll want to know how to use these if you have to do too much with hardware.
