Hello!

I have installed an EAP653 as AP for my Fritz!Box 5530 YW as the main router via a LAN cable from the basement to the 2nd floor. I just took all pre-configured settings and managed to establish a new SSID on the EAP after adding some standard 12V power adapter I still had in the house. The problem is now that the EAP seems to reboot again and again, dropping all clients from the network. When this happens is hard to say, sometimes several times in a row, sometimes after an hour, but nothing seems to help. I set up the EAP via the Omada controller app, but it disconnected once and shows as "Disconnected" ever since, although it is clearly running. When this happens the network is completely gone, I cannot ping the device. When I run the Omada app on my smartphone and this disconnect happens, I get a message: "Someone else connected to this device. You connection has been dropped" or something similar. I have no idea who could have connected to that device, there are no other active clients except for my laptop and mobile phone. I have run out of ideas what could happen here. Does anyone have some hints what I could have done wrong?

Thanks in advance!
