Blinking wifi LED

[arslano]

now i change the code as

sudo echo phy0assoc >/sys/class/leds/ath9k-phy0\:assoc/trigger

but it's written on the terminal windows is:

Permission denied

??

its pretty straight forward and it did the trick for my Dell E6400

lets start

open terminal
type the following in terminal "sudo gedit"

you will notice it opens gedit, now with root privileges

paste the script from Mobusbys post into the text file
save the file as "blink" in the following folder "file system>etc>network>if-up.d

now close gedit

in terminal type the following

sudo chown root /etc/network/if-up.d/blink

press enter

type the following in terminal

sudo chmod a+x /etc/network/if-up.d/blink

press enter


close terminal

restart machine


that should do the trick, if not post back


cheers

Whoa, whoa, whoa. Who said anything about going back to Windows? I used to use Windows, like 3 years ago. But besides being a primitive, clunky mess, Windows is entirely unsuited for the work that I currently do.

If anything, I'd go pickup a shiny new Macbook and carry on. But until I am forced to move off of Hardy or replace my current computer, that's all moot.

(That script may work to fix the blinking. If so, great. But Ibex also had a bad habit of constantly dropping connections on me.)

We'll just see what happens. Surely enough people will be annoyed by this that the devs will eventually correct it.... right?

Hi all!
I've just visited this forum. Happy to get acquainted with you. Thanks.

The files you want to change are in /sys/class/leds and are symbolic links to the LED controls. You can do

stat /sys/class/leds/*

to see where the links point to, but it is unimportant.

TX and RX are for transfer and receive (respectively), and control behavior when transferring or receiving data; assoc takes over when the card connects to an access point; radio takes over before association takes place, and just lets you know if the card is active or not.

This script is perhaps a bit more elegant, and works if you have multiple effected wi-fi cards installed. It only allows blinking when connecting. The LED remains solid and on at all other times (when the wi-fi card is enabled or when it has a steady link). I find this behavior minimally invasive but still useful for debugging and troubleshooting network issues.

#!/bin/bash

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

    # customize this loop to act on any relevant wi-fi cards
    for direc in /sys/class/leds/iwl-phy0:assoc
    do
        echo phy0assoc > $direc/trigger
        # do trigger blinking during association
    done
fi

Place this script in /etc/network/if-up.d/ (call it whatever you want) and do

sudo chown root /etc/network/if-up.d/<script name>
sudo chmod a+x /etc/network/if-up.d/<script name>

This worked for me with Intrepid and works now on Jaunty RC. Hopefully it will work for other people, too!

This script worked on Ubuntu 9.04 installed on a Dell XPS M1210 but now it does not work on Ubuntu 9.10.

i just did this last night on 9.10 on my E6400 and it works like a charm


can you step by step walk us through what you are doing?

sudo nano /etc/network/if-up.d/stopBlink

paste the the script then save.

sudo chown root /etc/network/if-up.d/stopBlink

sudo chmod a+x /etc/network/if-up.d/stopBlink

sudo -i

reboot

sudo chmod a+x /etc/network/if-up.d/stopBlink

sudo -i

reboot

grab mobusbys new script right above and do the following...this is what i did and works great

Appreciate the help but that method is the same as mine but the difference is you using gedit while I prefer using the console. That method did not resolve my issue. Also have in mind we both have different hardware. I can get the wifi led to stop blinking by disconnecting and connecting back to my wireless network. But once I reboot I have to do the same process again which is tedious.

It seems my little script needs updating for Karmic. Now there is an extra ":" in the directory names. This modified script should be a bit more flexible with names.

#!/bin/bash

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

    # customize this loop to act on any relevant wi-fi cards
    for direc in /sys/class/leds/iwl-phy*assoc
    do
        echo phy0assoc > $direc/trigger
        # do trigger blinking during association
    done
fi

Cheers!

It's seems that I miss this post by mobusby patching the script for Karmic. Thanks dude, this script works on my XPS-M1210 Laptop. Much appreciated.

The script not only stops the blinking but also kills the led. Now the led is always off in my Sony VAIO VGN-C240e laptop...is there something I'm missing?

UPDATE: Never mind. Now it's working perfectly....thanks!
