@boulder_bob I recently moved to a new room where it was not convenient to use a wired Ethernet connection, and it was recommended that I use a wireless extender instead. I did this and everything worked fine. One day I decided to see if a hard wired connection would sound better, so I ran my 30’ BJC Cat6 cable through the house to the router. The change was significant and not in a good way, the black background was now more gray. I reverted back to the Tp-Link extender and all was well again. My conclusion is that even well shielded Ethernet cables act as big antennas and collect noise. Try an extender, or insert an optical run and a short Ethernet cable on the system side. I think you will like the results.
Comparing Powerline Ethernet to WiFi for streaming audio
Thought I would share my findings.
I have a ROON based music server system with Tidal and Qobuz streaming services. Using Small Green Computer’s SonicTransport i9 Optical as ROON Core, connected via optical cable to a Sonore Optical Rendu (powered by Sonore Linear Power Supply) acting as ROON endpoint. This then connects to Chord Blu Mk 2 via USB, which upsamples and connects to Chord DAVE DAC via dual BNC.
Until very recently, I was connecting my ROON Core to my cable modem/router using Google Mesh WiFi. I was and still is very happy with the sound quality. My audio system is too far from my cable modem to run an ethernet cable from cable modem/router to it. So, I relied on Google Mesh WiFi with a seperate pod situated close to the ROON Core and connected via ethernet. The Google Mesh pod itself had a linear power supply instead of the stock wall wart.
But I just tried a Powerline Ethernet adapter. This uses the home’s internal power cables to route ethernet from one room to another. I always thought that running digital data on power cables was going to be noisy. I bought a NetGear Powerline 1200 (1200Mbps speed). There are more expensive and newer powerline ethernet models available up to 2000Mbps speed. But these come with dual ethernet ports and pass through filtered power outlets. I though for dedicated audio purposes, better to keep it simple and minimize electronics.
Bottom line, I was blown away by the improvement in audio quality of the NetGear Powerline Ethernet connection over the Google Mesh WiFi connection. Mind you, I was very happy with the quality from the Google Mesh kit but the NetGear Powerline ethernet kit was clearly better.
The sound quality improvement was immediate and very evident. More space between instruments and notes. Smoother, more image depth and more air around the notes especially the trailing edges. So, no doubt, the Netgear Powerline 1200 was far superior to the Google Mesh WiFi. I then swapped the Netgear for a similar powerline ethernet product TP-Link AV600. This was recommended by Small Green Computer. The TP-Link is smaller and has 2 pin power prongs. The Netgear Powerlines has 3 pin power prongs, so it has a ground connection to the power outlet. I found the TP-Link to take a step backward in sound quality. The image depth decreased. Soundstage was flatter and there is less air and space between notes and instruments. The TP-Link Av600 was sounding a lot closer to the Google Mesh WiFi. Just my observations, FWIW.

@zlone thanks for sharing your experience - makes me want to move the modem |
@boulder_bob You might try a repeater, it is a cheap experiment: TP-Link AC1200 WiFi Extender,... https://www.amazon.com/dp/B08RHD97QY?ref=ppx_pop_mob_ap_share |
I have a relevant situation. In my vacation home I have no Ethernet wiring past my modem location. I have installed an Eero pro 6 mesh system with base and two extenders. One extender is in my audio room, where I have a WiFi connected Auralic Altair G1.1 streamer / DAC. Since the Eero extender is located close to my equipment, I decided to try plugging the Altair into the WiFi extenders Ethernet port. I assume this would be called internet over power??? The result was much improved sound. I then swapped in a better Ethernet cable and was again rewarded with improvement. I do believe the last Ethernet cable goin into your streamer or DAC should be of quality.
