Home network router question

Hi,

A network question from an analogue brain.

Our internet provider recently transitioned to a system of hardwired modems with various pods ( Plume ) for the routers.  There is one Plume/router which is hardwired to the modem and the rest are plugged into wall outlets.  Unfortunately, the modem is in the built in stereo cabinet- which is less than optimal.  I want to move the modem and "main pod" to another location away from the cabinet. Three questions:

1. Is running an ethernet wire from my streamer/DAC to the main pod equivalent to direct wiring to the old stand alone modem/router?

2.  If I move the modem and main pod; can I run a cable from the main pod to an ethernet port ( to be installed ) in the cabinet and plug in my streamer?  Will this be nearly equivalent to hard wiring into my old modem/router?

Any thoughts?  Please remember when replying that I am an analogue guy trying to navigate the digital world with as little pain as possible.

PS  I don't want to connect via wifi.

Thanks
