Hi

I am thinking of buying a AX3000 system with several X50 and X55

i think I would like to hardwire where possible to improve signal. 
i also want to use router mode. 
I also want to avoid using a switch. 
So the scheme would be

- internet enters house via modem and goes to main deco

- I then use one of the 3 Ethernet ports in each deco unit to link to another deco unit. 
- and so on, using daisy wiring and not a hub / star wiring 

Would this work and is it ideal?

I have attached a schematic to try to explain 

all help gratefully received.
