@m-db I'm using the Bricasti M12 exactly like you would use the M3 into a white Xfinity "POD" that has the 2 Ethernet ports underneath. My Xfinity Router/Modem is in another room and I have a Roon Nucleus hooked up to a switch which is then hooked into the Router/modem. The Bricasti works flawlessly and you I choose my songs via either an iPad or my phone. Either way no problems.
