Issue with Orbi router

[Charles7]

I too have an Orbi router, and my Windows PC is connected by Ethernet cable to the router. Minimserver sends a stream via the cable to the router, which broadcasts it to the LAN. My UPnP renderer is a Denon LinkHS2, which receives the stream. I select the stream using BubbleUPnP on an Android device.

But my PC can also have a wifi connection to the LAN. You might figure out the two IP addresses for your PC, one for the Ethernet cable connection and one for the wifi connection. You can start with the LAN icon in your taskbar (see screen cap). Via this icon, you can close the wifi connection to the PC so that only the cable connection is active. (You might also get the same information from your Orbi router web page.)

Then in your browser confirm that you can go to the Web page for Minimserver. The IP for mine is: http://192.168.1.16:9790/ Yours might differ only at the .16, since we both have Orbi mesh routers.

One difference between your setup and mine is that you use Wiim or HiFi Cast. You can try BubbleUPnP if you have an Android device to narrow down where the problem is. It is a free app.
