Hi Leknes, and welcome to the forum

The some of the Intel wireless cards are known for flashing their LED with the iwlwifi and iwlegacy drivers (because they default to led_mode=0 [system] which is the equivalent of led_mode=2 [blinking]) .. it can be fixed though.

Try this...

Open a terminal and run:

Code: [Select]

gksudo xed /etc/modprobe.d/iwlegacy.conf

when a BLANK file opens, make it read:-

Code: [Select]

options iwlegacy led_mode=1

SAVE the file, then log off/on (or reboot).

The LED should now be ON when the wifi is switch on, and OFF when switched off .. no blinking.

Did that stop it flashing ?

[Leknes]

Still flashing. It looks like kind of a wifi icon that is supposed to be blue when on and red when of. It is also a touch button for wifi toggle.

[PCNetSpec]

Can you post the output from:

Code: [Select]

lspci -vnn | grep -i net

and

Code: [Select]

lsmod

And by the way, I never thought this old laptop could feel this nice, thanks everyone who made this!

[PCNetSpec]

Does running

Code: [Select]

sudo rmmod iwlwifi

then

Code: [Select]

sudo modprobe iwlwifi led_mode=1

stop wireless blinking ?

Be aware this won't survive a reboot, but if it works we can make it permanent.

[Leknes]

When I try the first line i get: [sudo] password for leknes:
Then I can't type anything

[PCNetSpec]

Yes you can .. remember, when entering a password in the terminal nothing gets echoed to screen (not even ******) just type your password, then hit enter.

[Leknes]

leknes@HP-Pavilion-dv7-PC ~ $ sudo rmmod iwlwifi
[sudo] password for leknes:
rmmod: ERROR: Module iwlwifi is in use by: iwldvm
leknes@HP-Pavilion-dv7-PC ~ $ sudo modprobe iwlwifi led_mode=1
leknes@HP-Pavilion-dv7-PC ~ $

[PCNetSpec]

It would be a good idea to copy these instructions to a text file first .. so you can undo if necessary, in case it kills your internet.

Okay try this...

Code: [Select]

sudo rm -v /etc/modprobe.d/iwlegacy.conf

then

Code: [Select]

gksudo xed /etc/modprobe.d/iwlwifi.conf

when a file opens that already has stuff in it, add a NEW LINE at the bottom that reads

Code: [Select]

options iwlwifi led_mode=1

SAVE the file and exit the text editor.

Reboot to test if the blinking has stopped ?


To Undo

run:

Code: [Select]

gksudo xed /etc/modprobe.d/iwlwifi.conf

remove the line you added at the bottom .. SAVE the file .. Reboot.

[Leknes]

leknes@HP-Pavilion-dv7-PC ~ $ sudo rm -v /etc/modprobe.d/iwlegacy.conf
[sudo] password for leknes:
removed '/etc/modprobe.d/iwlegacy.conf'
leknes@HP-Pavilion-dv7-PC ~ $ options iwlwifi led_mode=1
options: command not found
leknes@HP-Pavilion-dv7-PC ~ $

So I am guessing that I do not need to do the reboot and such?

[Leknes]

Sorry I see what I did wrong, doing it again.

[Leknes]

It's working perfectly now! Thank you!
