HOW TO IDENTIFY WLANS FAST?

Dear forum,

anyone knows how to identify WLANs without identify by MAC and winbox?

If I put 2xR52H in the top an low minipci connector.. I could see wlan1 and wlan2 in winbox.. I can identify it by MACs.. but.. if I put another R52H in the middle minipci connector.. It will be wlan3? WHY?

How it works exactly? In the users guide I could see that top minipci (the minipci that is more close to the board) must be “wlan3” and low must be “wlan1”.

Thanks,
