WAC6552D-S settings

Dear Zyxel,

I bought a WAC6552D AP, but I can not connect to it. I registered in a Nebula system, but unfortunately it is offline. If I searched for in the network and pressing the allotted IP address I will get this message:

"This AP is managed by AP controller. To manage this AP, please access AP controller's web interface."

I don't have AP Controller, I would like to use it DHCP through Poe Switch.

AP broadcasts Zyxel SSID to which you are free to join and there is an Internet access.

Thank you!
