I have an RPi 3b with Allo DigiOne card, running Volumio 2.692. I am having trouble using it as a DLNA renderer when connected by WiFi.
If connected by Ethernet, Volumio is visible as a DLNA renderer on my home network. If connected by WiFi, it usually is not visible. If I run the config wizard, it becomes visible until I close the DLNA control point (BubbleUPnP), then is not visible when I reopen it.
It is always possible to use the Web interface, but I prefer to use it for DLNA through a control point.
Is there a solution to this that I can apply through the Web interface (without connecting monitor and keyboard)? I find mentions of this problem from as long as 5 years ago, but the answers all seem complicated to me, as they use a command prompt, with no instruction of how to open one. I am not averse to entering commands, but I have no idea how to go about it with this headless box.
Or is this still an unsolved problem? If that is the case, is there another headless OS that I could try?
