Minimserver in Windows Explorer - normal flip-flop or clue?

[Charles7]

I went through the various power off-power on procedures. Randomly, BubbleUPnP will or will not find the Minimstreamer library. That is, no change.

With rising vexation over the problems around UPnP, I bought a Netgear Orbi RSR850 router and installed it in place of the TP-Link Deco AX3600 router and satellite. The Deco gives you no information nor control over UPnP. The Orbi has controls for on/off and advertisement time (which I reduced from default 30 minutes to 4 minutes). Its documentation does not mention IGMP; Web chatter says Orbi does not support IGMP snooping.

The result: nothing has changed.
