David Dombrowsky, thank you for reporting this and helping make Ubuntu
better.

Regarding the LED blinking when WiFi traffic is occurring, while you may
find this annoying, and it could be many others find this also, this
being the default action it isn't considered a software bug. Given the
fact you have an option to turn it off in software, you also have a way
to address the issue as you see fit. If anything, the LED light
installed into the laptop would be brighter than preferred, making this
a manufacturer design issue you have.

Please feel free to report any future bugs you may find.

Title:
  iwlegacy/iwl3945 driver flashes LED on traffic by default

Status in linux package in Ubuntu:
  Invalid

Bug description:
  This bug is still present in 16.04.  When using the iwlegacy driver,
  the default behavior is to have the blue LED indicator flash whenever
  traffic is going over the wireless.  This is annoying, as it is in the
  user's face on most laptops.

  The workaround is to add something like this to a new file named 
/etc/modprobe.d/iwled.conf 
   
     options iwlegacy led_mode=1

  I suggest that this mode be the default, and require a configuration
  change to ENABLE the flashing.
