Disable wireless activity LED for 12.10

[bdrieck]

Brand new to Ubunto. installed it on a dead windows laptop and brought it back to life. I love Ubunto!! I have NO experience in Ubunto or the terminal. I'm not afraid to try and learn. the led that shows my wireless adapter is turned on blinks with internet activity. prior to this the light would stay solid blue when on and now it blinks. It is annoying to me. I've searched and found countless threads about this issue but with the older versions of Ubunto 12.04 and prior. My wireless adapter is: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

again as I am as new to this as anyone can get if somone could walk me through trying to fix this I would greatly appreciate it.

thank you !!

We are going to try a conf file and see if it helps. Please do:
sudo gedit /etc/modprobe.d/iwlegacy.confA new empty file will open. Add one line:
options iwlegacy led_mode=1Proofread, save and close gedit. Now, let's try it immediately:
sudo modprobe -r iwl3945
sudo modprobe iwlegacy led_mode=1
sudo modprobe iwl3945Any improvement?

Thank you Chili! seems to have worked. in laymans terms can you describe what I did by typing the first code and opening up the file and entering the 1 line? then what happed when I entered the next 3 codes in? after entering the first 2 codes:

sudo modprobe -r iwl3945
sudo modprobe iwlegacy led_mode=1

I got messages warning messages about ignroing lines and options.I don't expect you to teach me Ubunto/linux in this thread. Just curious as to how this works?

thanks again for your help.

I got messages warning messages about ignroing lines and options.We ought to take a look and see if we need to tweak something. Please repeat the sequence and copy and paste the messages in a text editor so you can post them here.

Your wireless driver is iwl3945:
Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)I also know because I have one! According to modinfo, it offers no parameter for LED behavior:
chili@LAPTOP410:~$ modinfo iwl3945
filename: /lib/modules/3.5.0-18-generic/updates/drivers/net/wireless/iwlegacy/iwl3945.ko

parm: fw_restart:restart firmware in case of error (int)So we check its dependencies, first iwlegacy:
chili@LAPTOP410:~$ modinfo iwlegacy

vermagic: 3.5.0-18-generic SMP mod_unload modversions 686
parm: led_mode:0=system default, 1=On(RF On)/Off(RF Off), 2=blinking (int)
parm: bt_coex_active:enable wifi/bluetooth co-exist (bool)Bingo! So we unload the driver iwl3945 with modprobe -r which takes the whole family, including iwlegacy with it. We reload iwlegacy with a driver parameter and reload the driver. It works!

Our conf file instructs the system to load iwlegacy with the LED parameter automagically every time it's loaded.

Post those warnings, please and we'll do some housekeeping.
