There’s one of the MikroTik Chateau 5G models.
System version 7.19.2.
It has, among others, an LED marked with a Wi‑Fi symbol.
That LED lights up during device startup and quickly goes out.
After that, it never lights again.
In /system/leds I only see LEDs from led1 to led5 and poe‑led.
LEDs 1–5 are mapped to the modem’s signal strength.
When I enable poe‑led, nothing lights up.
When I try to activate other LEDs, e.g.:
/system leds add leds=led1 type=on
or user‑led, led6, etc., I get an error:
input does not match any value of led
Is there any way to list all physical LEDs?
Of course I could assign any other LED to Wi‑Fi, but since there’s a dedicated one, I’d like to use it.
The solution turned out to be simple, and it also revealed that I had been looking in the wrong place.
The MikroTik device had been used before and someone had already upgraded it to the latest version. I received the MikroTik without any Wi‑Fi support packages. I installed wifi‑qcom‑ac‑7.19.2‑arm.npk and enabled both Wi‑Fi networks (2.4 GHz and 5 GHz)
The Wi‑Fi LED wasn’t working, so I posted a question in the group.
Later, though, I noticed that my computer was connecting to the MikroTik’s Wi‑Fi network but wasn’t getting an IP address via DHCP.
It turned out I had forgotten to add the Wi‑Fi interfaces to the bridge. Once I added the Wi‑Fi to the bridge, the client device received a DHCP address, and the Wi‑Fi LED came to life.
However, this LED still doesn’t appear under System → LEDs, so it’s handled differently—just like the power/status LED, for example.
Yes, generally speaking each Mikrotik device has different provisions for leds, also “dark-mode” only works on some devices (and not on other ones) some devices have only a “user” led (which is also the only one configurable).
What you see in System->Leds on the specific device is all you can fiddle with.
