@MarioRuck ok, I use ubuntu controller too, I also have EAP653 which works without problems, is the controller installed directly on ubuntu or are you using some container stuff.

@MarioRuck I seem to remember that the firmware requires some new ports, do you have a local controller or is it remote? Which ports have you opened to the controller? You need this port to be opened...

@b-shu select download and go to firmware in the left menu https://support.omadanetworks.com/en/product/er605/v2/?resourceType=download

@AngelaGarza Yes, if you have an ISP router connected to the Omada router, that could be true. I see you have a private IP on the WAN, but you haven't said anything about which router you have or how...
