Comment 14 for bug 189889

just to resume.

after upgrading with this patch my wifi led stopped working. It goes On during first part of boot, then on the middle it goes Off.

So I removed from my /usr/share/acpi-support/state-funcs
 the above lines

# Pass '1' to light LED and '0' to dark LED
# setLEDAsusWireless()
# {
# action=`test "$1" -ne 0 && echo 1 || echo 0`
# test -w /proc/acpi/asus/wled && echo -n "$action" > /proc/acpi/asus/wled
# test -w /sys/devices/platform/asus-laptop/wlan && echo -n "$action" > /sys/devices/platform/asus-laptop/wlan
# }

Now led is perfectly working again.
If I execute from shell this command,
echo 0 | sudo tee /sys/devices/platform/asus-laptop/wlan

It returns 0 and the led goes Off

echo 1 | sudo tee /sys/devices/platform/asus-laptop/wlan

It returns 1 and the led goes On

all other commands was not having any effect on led.

I hope to have been of some help
ty so much for your continuous and great work ubuntu rocks!!!
