Linksys WRT1200AC and LEDs?

Installing and Using OpenWrt
1

Hi

I just installed openwrt on my linksys WRT1200AC router and everything seems to work fine except the LEDs on the front.

power,wifi and so on are totally dark while the ports seem okay if I plug in something.
(The LEDs worked fine with linksys fw and DD-WRT )

Any hints why? Tried to play around with the LED settings but could not get them working.

Thanks in advance,

Michael

You don't mention, were the LEDs in question listed in the LED settings section?

If so, what "playing around" did you do?

On a lot of devices, OpenWrt allows [custom] configuration of some LEDs.

Sorry for being unclear.

I followed the following document about LED configuration.

My webgui shows:

Shouldn't this make the power LED show something?

B.t.w using OpenWrt 25.12.3 r32912-6639b15f62 / LuCI openwrt-25.12 branch 26.128.23199~e5f2fb1

  • Where's the power LED configuration?
  • For WAN LED, set the trigger to the following 3:
    • Link
    • Tx
    • Rx

Test and report your results. Use the web GUI.

BTW, I'm not sure what (or why) you're attempting here.
