Minimserver takes long to show up

[tarnkappe]

IGMP is activated for wifi and I can deactivate this. (I will test if this will be an advantage for the different upnp apps that I am using.) But as the hardwired uniti does not see the minimserver, too, I tried to find out if the two routers have IGMP activated for their LAN ports. This is difficult as I could not find a clear statement. It seems that at least the fritz box has IGMP enabled. For the asus router I could not find an information. Also I could not find an option in both routers to de/activate it for LAN.

Does a multicast member (an UPnP server) not have a chance to send an IGMP "here I am" package after starting up but has to wait for a IGMP query from the current IGMP master? Maybe ohNet should send such SSDP alive packages for a while until it received an IGMP package.

As far as I understand, IGMP is a good thing that one should have enabled, because it lowers the number of network packages flooding around with multicast traffic. It would be a pity if UPnP conflicts with this conceptionally.
