I've got no idea....

The Marantz actually has a considerable amount of controls for networking. I can set a static IP within the Marantz (which i've tried), there is also DHCP as a networking option (which i've also tried... ) I should note that there is also a Diagnostic option; which confirms that the physical connection is good. ect.. It also reports if the unit has an internet connection... This test has always failed.

I should note, there is also a Maintenance option, which is suppose to be reserved for customer service, or a pro installer.

This situation is somewhat perplexing, like you Casey i thought it would be straightforward and super easy.. All of the other settings on this unit has been completely painless to configure.
