@Melvinius then you probably have a defective access point.

@Melvinius It could also be a firmware problem. here is a guide on how to do firmware recovery https://www.tp-link.com/en/support/faq/3186/

@Melvinius ok are you sure the cable is ok it sounds like the ap is faulty. ap gets power since it lights up. have you tried meshing wirelessly to another ap. it sounds like the ethernet port is...

@Melvinius have you tried to connect access points directly in the switch with a short cable? I suspect you have cable problems.

@djwujek All screen is from controller

@nasheayahu but then I don't understand why you are on the TP-Link forum when you don't have TP-Link products. dhcp vlan which is controlled by pfsence and netgear is in my opinion the main problem...
