I'm over my depth.

I've been running 

=> A Starlink modem/router

=> A Starlink Ethernet adapter to 

=> A TP Hardware Controller to

=> A TP-Link TL-SG108E switch to various mesh antennas and devices

I bought TP-Link BE9300 router for better security and latest wireless version 7.

How should I wire in the new router keeping the rest? Do I go from Ethernet adapter to the router and then out the router to the ardware controller?

Or, do I need to use the hardware controller OR the router, but not both?
