I have an EAP610, EAP610-outdoor, and EAP615-wall; all cabled. I added a cabled EAP225-outdoor to cover a dead area on my yard, but it will not connect to my phone due to a security issue. I have to forget and reconnect to the network to access it, then back again when I leave the area. I also have a Wyze Cam and a smart plug that will not receive an IP address from the EAP225-outdoor. Those items i forced to attach to any of the 6xx AP's and that settled that issue. What setting would prevent the seemless roaming between the 225 and the 6xx AP's? I have an ER605, SG2210p and an old laptop running Ubuntu Server with the controller software on it. One note is that the 225 derives its backhaul from an unmanaged Netgear switch and is powered by the OEM POE adapter, not from the SG2210p.
