UPNP not working on RBR20/RBS20 in AP mode
I currently use my RBR20/RBS20 with a HomeHub3000 router from Bell Aliant. The Orbi is in access point mode. The bell router does all routing. This system has worked fairly flawlessly except today whe...

There's that darn IGMP Snooping:

"Optimizes multicast data streams". WTF???
(Interesting that the official Data Sheet does not mention IGMP Snooping.)
This all sounds too good to be true
https://en.wikipedia.org/wiki/IGMP_snooping
But, I cannot reconcile this enthusiasm with that paragraph in the article on UPnP:
https://en.wikipedia.org/wiki/Universal_Plug_and_Play where it says:
If IGMP snooping is enabled on a switch, or more commonly a wireless router/switch, it will interfere with UPnP/DLNA device discovery (SSDP) if incorrectly or incompletely configured (e.g. without an active querier or IGMP proxy), making UPnP appear unreliable.
Typical scenarios observed include a server or client (e.g. smart TV) appearing after power on, and then disappearing after a few minutes (often 30 by default configuration) due to IGMP group membership expiring.
IGMP snooping is really common. So far, I have not found many inexpensive switches that do not appear to have this feature, such as:

Why does a '308' cost half what a '108' costs???
Before attempting to run an ethernet cable, I would probably drop $22 (+tax) on a Netgear GS308 and see 'anything changes'.
(I do not trust Netgear to have left IGMP Snooping out of the product and simply not mentioned anything about it. But I am a cynical old fart.)
There is always a (dim) chance that support that either Synology or Naim has an opinion on IGMP snooping. Since Naim relies entirely on UPnP, they might be the place to start.

I also have a D-Link DGS-108, it's a un-managed switch. No IGMP protocols here. Same goes for the NG GS108/105s I have.

FURRYe38 I want to agree with you in theory, but the problem is once the D-link was removed from the chain and the Netgear switch inserted all problems went away. So the D-link DGS108 was doing something. Maybe it's a Netgear to Netgear thing, I don't know. But for me the DGS108 prevented UPnP working reliably. Even when it was working on the DGS108, it was slow and buggy from wired connections, and it wouldn't pickup all my UPnP servers.
With the GS108 in the chain, it sees everything - reliably and fast.
It's possible that particular switch you have is faulty. Glad the NG switch resolved it.
Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
