I have an order to have Suddenlink/Altice installed in my home (they are finally providing service to my area) - I have order the 1 gb internet package.

I have 2 questions, a "simple one" and a "main one".

Simple question: the tech told me to make sure the modem I buy has Docsis 3.1.  Looking at reviews, I am thinking the Orbi CBR750 is the right choice.  My home (~2750 sqft) has cat6 run throughout, into a centralized wiring closet.  In the wiring closet sits an unmanaged gigabit 24-port network switch that all of the rooms are wired to.    Is that Orbi the right choice AND will it (should it) just connect to the unmanaged switch to provide service to the ports in each room?

Main question:  I have 2 outbuildings, about 100' from the main house.  Both of the buildings also have cat6 run from that same wiring closet above.  Both outbuildings are sheet metal (which blocks the wifi signal).  If I get an Orbi "satelite extender" for both buildings, will they work using the cat6 - or do they have to get their signal from the wifi in the house?
