Just as an aside, I had a nice improvement, not night and day, but significant, by inserting a short length of optical cable between two TP Link Media Converters at the end of my run of Cat6a from my router, then a short run of Supra Cat8 with Telegarten (spelling?) connectors at each end, into the Node.
My router sits in the adjoining room, with the TV, TV service box, Sonos gear, smart lighting bridge, and few other bits and pieces. As you can imagine, not the quietest of electronic environments 🤔. This relatively inexpensive tweak, dropped the noise floor further, and "cleaned" up the overall signal.
I got this suggestion from this forum, I can't remember the contributor, but definitely worth doing considering the low cost
