Minimserver takes long to show up

As far as I have read there can be several IGMP query instances in a network. But only one is the main instance who is doing the queries. If you switch off this one, another instance can become the main instance. (similar as SMB works AFAIR.) So this main instance does not need to be the main router, does it?

But I could not find an option for this in the main router fritz box anyway. You can "hack" into the router and turn it off manually by stopping/configuring a daemon, but I do not like to touch this important device that way because there will be an annoyed family if internet access does not work anymore if I am doing something wrong...
