This appears to be a bug exclusive to "/sys/class/leds/iwl-phy0:assoc/trigger".

As Volker mentioned here (2008-11-08), if you run the following command:

"sudo echo phy0assoc >/sys/class/leds/iwl-phy0\:assoc/trigger"

the LED will behave as expected, until the network reconnects again. That is all my Ubuntu computers (mostly Dell) need, and it appeared in Intrepid and now Jaunty releases.

For some reason, even though that parameter is shown as "phy0assoc" (cat /sys/class/leds/iwl-phy0\:assoc/trigger), it is NOT (apparently, it's phy0tx or phy0rx) and must be set after the interface scripts have connected the link. I poked around some of the various scripts, but have not found an "automatic" fix -- maybe someone with more knowledge will know how to include this at the right place in the networking scripts.

It's sad that such an annoying problem cannot be resolved and integrated more quickly. I created a little script file to do this for me, but I have to run it every time I connect to a network -- on the positive side, I can quickly notice if my WiFi link was dropped while I was away. :-)
