Solution to flashing wifi light in fedora 13

I have Compaq nc6400 laptop which have built-in wireless card.
(Intel Corporation PRO/Wireless 3945ABG)

1. I have enabled wireless and a blue WiFi light started flashing non-stop with traffic.

echo "#add to /etc/modprobe.d/wlan.conf" > /etc/modprobe.d/wlan.conf
echo "options iwlcore led_mode=1" >> /etc/modprobe.d/wlan.conf

2. Restart the machine
