Ken, @ipeverywhere gave you the answer. The IP address of your Rock is not in the same IP range as the rest of your system. Until you get everything back on the same network you will not be able to resolve your problem. Do you know hw to check the IP address of the various devices in your system? In my system everything is on a network with the address that begins: 192.168.1.XXX. You need to resolve this before you will be able to listen to music via Roon.
