Hi @Wes. The 851N is hardwired via ethernet directly into a network switch. The two Roon cores I’ve tested (never on at the same time), along with the Pi I use for testing, are all also hardwired into the same network switch, so the path between either Roon core and the Roon clients are always ethernet.
I’ve been successfully streaming to the 851N from either core by changing the Dash URL to HTTPS, and can reliably see the stream die when using HTTP, FWIW. The working URL is https://ice55.securenetsystems.net/DASH7
I don’t follow the USB ask. What do you want me to connect via USB?
Thanks!
