On the Linksys 3200ACM with clean LEDE 17.01.3
it's not possible to turn off WIFI LEDS.

Any write operation to /sys/class/leds/rango:white:wlan_2g/trigger
or cat /sys/class/leds/rango:white:wlan_5g/trigger will cause the WiFi
to stop operating (accordingly 2G or 5G depending which trigger we want to change).
Steps to reproduce:
echo none > /sys/class/leds/rango:white:wlan_2g/trigger
What is strange that after boot the WiFi leds are operating (flashing according to tx/rx),
but current trigger reported by sysfs is anyway none:
cat /sys/class/leds/rango:white:wlan_5g/trigger
[none] nand-disk usbport mmc0 timer default-on netdev phy0rx phy0tx phy0assoc phy0radio phy1rx phy1tx phy1assoc phy1radio
The writes to the brightness value are ignored.

Also there are no controls for the wired ethernet switch leds.
All controls that are reported by sysfs:
ls /sys/class/leds/
