Was looking into the blinking wifi led on a dell D630 running fedora 16 and found the led_mode option for the module iwlegacy:
cat <> /etc/modprobe.d/solid_led.conf
option iwlegacy led_mode=1
EOF

For Ubuntu 12.04:

$ sudo nano /etc/modprobe.d/iwlwifi.conf

paste

options iwlwifi led_mode=1

Then reboot your laptop / reload module.

instead of restarting you can also

# rmmod iwlcore
# modprobe iwlcore

in kernel 3.0 this module is called iwlwifi, so you have to change iwlcore to iwlwifi if youre using kernel 3.0 and above

For me, using “wlagn” instead of “iwlcore” did not work on Ubuntu 11.10. I used “iwl_legacy” instead which did work. Apparently, iwlcore is renamed since kernel 3.0

Thanks Matt, on 11.10, “iwlagn” did the trick.

How is it possible that somebody on the Ubuntu side had this “brilliant” idea of the blinking wifi LED ? That’s madness. And moreover it’s quite complicated to deactivate (when you don’t know this exact parameter).
As times passes : Ubuntu becomes worse and worse. I’m seriously considering all my Linux boxes to something else.

For Ubuntu 11.10 replace iwlcore with iwlagn in the line above, so that it reads:
options iwlagn led_mode=1

Second solution worked great on the HP2530p

Thanks to all!

Thanks for this, works perfectly on Natty too!

If you want to avoid rebooting you can do ‘modprobe -r iwlagn && modprobe iwlagn’ instead, which simply reloads the module.
