I had already tested that by using cables instead of WLAN (most of my
radios have an extra ethernet port). But meanwhile I had the feeling
that the desktop switch might be causing the issues.

It took me some time to set up tests and rewire the network here. I
think the WLAN access point (actually a FritzBox router) is not the
culprit (at least not alone). Everything works fine now when I
plug the DLNA server and my FreeBSD desktop box directly into the LAN
ports of the FritzBox. This leaves me with the impression that indeed my
desktop switch is causing the issues. According to the manual it does
not support IGMP at all, maybe this is the reason for all the trouble?

Makes me wonder why it worked before, though. I replaced an older WLAN
access point with the FritzBox a couple of days ago, but I think DLNA
worked right after that. Maybe the clients somehow cached the servers
they knew about, and the issues only started popping up days later when
rebooting them? Another difference is that the old WLAN access point
did not have an ethernet switch built-in. Now that I have two switches
connected, would IGMP be required between them to pass the multicast
packages around properly?
