VirualAP shows inconsistently

RouterOS General
1

I have strange problem with two VirtualAPs on top of signle physical wireless interface. One of the VirtualAP’s shows SSID inconsistently. Actuallu iti is mor hiden than visible. Other VirtualAP shows normaly.

I have this issue on two AP’s. Different RouterOs versions, one is on PC one on RouterBoard. I tried replacing wireless cards but problem stayed.

I noticed, when i disable the second VirtualAP, the first (one that was loosing itself) then shows normaly.

Is there something I can do with settings to prevent this?

I solved a problem, so here it is if someone else gets to the sam trouble:

VirtuaLAP’s must have different MAC. I noticed that on both locations where this problem arised, two VirtualAP’s had the same MAC (I guess I copied one interface to create another VirtualAP, so MAC stayed the same).

Maybe Mikrotik should refuse to accept settings if it leads to situation that two interfaces have the same MAC.
