Red light on rb912G-2HPnD

RouterOS Wireless Networking

Hi

I keep having a red light go on in the rb912G-2HPnD (photo attached)
it has 2Ghz and 5GHz 802.11ac capability.

it is setup as a CapsMan controlled AP device attached to the RB2011 router running CapsManager.

the red light goes off when I re-provision the AP but pretty quickly comes back on again.
and it goes off when I have no devices connected.

is this just to show the board has registered devices as it seems it may be as simple as that,
or is there something wrong I should be looking into?

Looks like the card LED is on. There is text on the card, that explains meaning of each:

the arrow is showing the one that is lighting up. I had to restart it to take the photo and clear all the wireless connections. where can I find info on the various lights?

like you see on the illustration next to the arrow, it is the lowest level of signal.

ok, thanks for that. any ideas on how to get the signal up higher? there is not much interference where I am from other wifi sources, and the laptop is right next to the AP and yet I am only ever seeing that level.
