Tam,
Yes, the IP address is my Router IP Address.
"My Network Drive" is the drive I have connected to my router that serves as NAS (Network Attached Storage), not the internet. I have a mirror of all of my music on that drive, so that anyone on my network can access it.
I don't use internet radio, so I have not tried that yet.
Here is a screenshot. My Network Drive (Readyshare) has the IP address 192.168.1.1 (most routers have that address). On that drive, I created a directory called "USB_Storage" and in that directory, I copied my entire "Music" directory from iTunes there. When I entered the correct info (shown in a post above), the AA software "found" my music. The AA software is shown playing "Loves Me Like A Rock" from that directory.
