I spent yesterday soldering a new fuse into the Denon AVR-X1100W AVR. The display was totally black, making it impossible to diagnose anything related to the AVR. With the new fuse, I can see much better what is going on with the network. With the AVR alone, taking Control 4 out of the picture, the network doesn't transmit/receive data regardless of whether I use WiFi or direct Ethernet cable into the router. The AVR WiFi does connect, and the ethernet shows a link, but running Pandora on the AVR still says "no network" either way.
I think the reason the network doesn't connect is because the devices were set up with static IP addresses. I suspect static IP's are preferable for C4, but I think that's why they can't access the network even when plugged directly into the WiFi router ethernet ports.
The Denon has the following settings:
From the front panel display, the C4 4-zone amp has the same settings except the IP is 10.0.1.72. The C4 controller doesn't have a front panel so I can't see it, but it's almost certainly "71" or "70" (the C4 streamer also has an address I'm sure).
I don't know if this WiFi router was ever used with the C4, so it may not be set up properly. I'm not sure what I need to do on the WiFi router to make it work with those static addresses. I also have a Netgear gigabit switch that was originally used -- I can put that back in if that will make the static IP addresses work.
The only computer I have here is a Macbook Pro, that has only ******* USB-C ports and no Ethernet, so I can't connect directly to the WiFi router for admin access.
