I don't even need to ping it. When I go to the Network Map, it's there and connected. When I click on the DENON icon, it takes me to the web interface where I can control receiver from a web browser. I can adjust the volume and turn the different zones on and off, go into setup and change stuff, etc. When I go the extra step and ping it, it replies. I don't see how it would be a routing problem if the same feature on my laptop works fine.
