Best way to connect Hub5 to TP Link AX5400

[Ish24]

Hi, 

I’ve bought the TP Link AX5400 and planning on using that as my router. My Hub 5 is in my office and so will the TP Link Router which I want to connect to my gaming PC which is also in my office. I’m also getting the Deco S4 so I can connect my TV and upstairs PC via Ethernet. 

Is the best way for me to change my Hub 5 into modem mode and connect the Ethernet to the WAN port of my TP Link router?

And what is the best way for me to connect my Deco S4’s so I can use the ports on it to connect to my PC and TV upstairs?
