Thanks Eric. I provided additional info to my post that should help.
So to answer one of your questions, I have tried playing directly out of the device (Node) and have had success. Meaning if I play Tidal straight from BluOS, it works without skipping. If I use Roon, it works but has its hiccups.
I also can’t hardwire the PC to the router bc of apartment logistics. In my house (that I moved from a month ago), I did have the PC hooked directly to the router and it worked well
