@RAL24 Yes, that's what I have as well. see image in https://community.tp-link.com/en/home/forum/topic/717372

  @Alexandre. Thank you so much for your help. Much appreciated. 
 

I do have a follow up question; does this mean if I use daisy wiring I need to use "access point" mode? And is this a disadvantage?

I say this because I read that

in "router mode" 
Satellite Decos must be connected to the LAN port of the main Deco or a switch connected to its LAN port to avoid a network loop.

in "access point mode"

You can wire satellite Decos to any Deco unit or even directly to the existing router/modem, optimizing connections in complex setups.

You will not need to use Access Point mode.
