Factory Reset All devices and did firmware updates.  Can login to each device individually and they are all on the same network connected to an unmanaged POE switch.  I want to adopt (3) EAP645's but it will not find any devices to add.  I can scan my network and see the EAP's are assigned an IP Address and are all pingable but for some reason controller can't find them even though everything else can!  Doesn't make sense to me.   Any ideas?
