While there's lots to like about my current laptop, one thing that had been quite annoying was the wireless indicator led. For a long time, it didn't function at all, because iwl4965 didn't contain support for driving it. Recently (effectively starting with Fedora 9 for me), that support came in, but now it's not annoying because you can't tell whether wireless is enabled, rather because the led is blinking all the time, which is a distraction.

I liked the behavior of my old laptop's ipw2200 much better: blink while searching/associating with a network, and then stay on constantly. Happily, Erich Schubert just pointed out how to fix the iwl4965 blinking behavior. That script is (I think) for Debian/Ubuntu, and a slightly different kind is needed on Fedora. I'm not sure this is the best way to go about it, but at least it works for me: put the following in /etc/NetworkManager/dispatcher.d/iwl-no-blink

#!/bin/sh
if [ "$0" = "wlan0" ]; then
    for dir in /sys/class/leds/iwl-phy*X; do
        echo none > $dir/trigger
    done
fi
