Network Switches

@david_ten 
Thanks, this is great info.  I never considered wifi because the DS Jr only accepts a hard wire connection but I'm sure the satellites have an ethernet jack.  I actually researched mesh wifi a couple months ago to get better reception throughout the house  and decided to hold off.  I  guess I need to revisit that decision.

@treebeard1   Yes, the satellite will have at least one, usually more LAN ports.

If you go with this approach, consider brands/models which have larger "open" space access for the LAN and DC power cables. It will allow for easier cable connections, especially if the cables are thicker / stiffer. It will also allow for the satellite unit to stand properly "upright."

I'll probably go with Google.  $150 for three at the moment.  I've seen worse.

great thread, recent posts are an incredible sourcebook for improvement investment…..

I have had an Orbi mesh system for a couple of years now.
Although I run fiber from my main router to my main system and that works great, I operate my garage/outdoor system through one of the mesh satellites as described by @david_ten below with a 0.5M CAT8 cable from the Orbi satellite to a Metrum Baby Ambre then Jade DAC and it too sounds great with no issues (drop outs, etc.) whatsoever.  I use the stock power supply on the satellite with no perceptible detriment to SQ but I do use LPSs on both fiber converters associated with my main system.
