Hi, is there a reason why you are using two different subnets? Is your firewall blocking access between subnets? 

@Lander7  The Deco mesh network automatically created the new subnet. I don't see a way to route traffic from that subnet to my wired subnet. When I was using a forti AP it automatically did this between the two subnets.

If you're using it in router mode, then it won't act like an AP. You'll need to run it in AP mode or if you need it in Router mode, likely let the Deco run the network, wired and wireless, in terms of DHCP, DNS, etc.

Just thought of something else; Try changing the subnet mask in the LAN IP area under Advanced to 255.255.0.0

Changing the subnet is a great idea

Does the mesh network exist in both AP and Router mode?

It seemed to me that changing the mode broke the mesh and turned them all into separate access points.
