Blinking wifi light - Intel Pro Dell Wireless WIFI 3945 card in Dell D630 Laptop

[Max Pyziur]

Greetings,

I swapped out a stock Broadcom wifi card for an Intel 3945 card and now my
Wifi indicator light blinks continually. I tried some of the
recommendations that I've found (create an /etc/modprobe.d/iwlwifi.conf
file with the line:
options iwlwifi led_mode=1


Subsequent rebooting does nothing to eliminate the annoyance.

The reason that I swapped out the Broadcom card is because it would stop
functioning after a certain irregular period of time, and
"systemctl restart NetworkManager" would not restart it (resorting to
plugging in the ethernet cable, or rebooting).

Any suggestions would be greatly appreciated (either how to keep the
Broadcom card from dying, or getting rid of the Intel card causing the
wifi light to blink).

Thank you.

One thing you didn't mention: aside from the blinking lights, does the
card work properly?

The Intel card seems to work correctly. I haven't done any diagnostics;
but after installing, I did a yum update (on F21), and things worked as
they should.

Also, I'm ssh'ing remotely to a box, and everything seems to be in order.

Thanks.

Have you tried a piece of black tape? :)

I was stuck trying to decide whether to use duct, masking, electrical, or
teflon tape.

The following two resources helped:
http://www.tomdesair.com/blog/2012/04/stop-the-blinking-wireless-led-in-linux/

and

https://wiki.debian.org/iwlwifi

The file that I created was:
/etc/modprobe.d/wlan.conf

It contains the following line:
options iwlegacy led_mode=1

Reasoning: the Intel WiFi card is a 3945. Based on that, it uses the
iwlegacy driver.

That got me home.



fyi,

When in doubt, try gaffer tape. All those others leave a sticky
residue. :)

Ah, nice. In reading this thread, I was remembering that my laptop
(Thinkpad X230) used to have a very blinky light, but now (kernel
4.1.2-200) it is steady on -- even though led_mode is 0. For whatever
that's worth.

Good. I asked because the lights may have been a symptom of a bad card
and I wanted to eliminate hardware issues.
