Here is a topology diagram of my working envornment using Ethernet backhaul. It has been in production for 2 days - so far so good. The only thing I notice is that the satelite Deco's will...

Yes that is the behavior I observe after receiving and setting up - thanks for the help.

If all the Deco's are in router mode in a star topology with an Ethernet backhaul, how do we ensure only one of the Deco's is the DHCP server? Is this possible?

Setup: Hub and spoke AKA "star" topology (Cisco switch in the middle) - wired backhaul. Can the main Deco be in router mode while the spokes are in AP mode?
