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

OP,

It is simple and cheap to connect an Aurender in a house with WiFi. You just buy a wall wart wifi extender… $69. Plug it in near your streamer and run an Ethernet cable between the extender and streamer. I have a $150K system running this way (with an Aurender streamer) and a $15K headphone system (with a different Aurender streamer) and they sound fantastic. I know of lots of world class systems that work this way. Great streamers like Aurender work great this way.

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.
