Good streamer that does not need wi-fi or internet to play local files

Power over ethernet or ethernet over power?  Confused again but who cares as long as it works.  Thank you @ghdprentice.  I like awesome tech like this...

Avoid Ethernet over power… this communicated via the power lines. This is a dirty way. You want to use a wifi extender… though the air… for instance:

Got it.  Almost make a mistake.  What brand do you use?

I use Netgear because my router/modem is netgear. They say it doesn’t matter… but after being in IT for over thirty years, I still like buying from the same company… the same support team if something goes wrong.

My streamer can go to the router via fiber, but can also use fiber to the NAS or any of my hard/flash drives.  It is pretty cool because I have a network built into my streamer so I can just plug into the network and control my streamer from anywhere in my house.
