after upgraded to 6.12 my SXT 5HPnD LED indication has stopped working. All good work, but earlier LED indication shows the strength of wireless signal.
how fix it?

Have you installed LED package ? Try to check if system/leds is set to correct type for wlan-led.

in "system/package" i do not see LED package, but it was never there. In System/leds a single entry:
Type: interface activity
Interface: ether1-local
Modem Signal Threshold: -70 (grey)
LEDs: user-led

I had this issue with ROS 6.8 through 6.10 that LED settings suddenly get lost.
Seems to be fixed in 6.12

To re-enable your signal strength indication do this:

ros code

/system leds
add disabled=no interface=wlan1 leds=led1,led2,led3,led4,led5 type=wireless-signal-strength

Don't forget to adjust the wlan1 interface name to your naming.
