Dlna server not appearing on wifi
Dlna media server not appearing on wireless network. I tried to upgrade and downgrade firmware as per other discussions. Server appears and works just fine on wired devices in same vlan. But no wirele...
Well this was an exercise in frustration.
I can say that the Nighthawk APs do not appear to be at fault.
The issue "suddenly" resolved itself and the DLNA servers suddenly started appearing to all of my wifi connected devices.
I am going to assume this was some issue with IGMP on the Cisco core switch.
I cannot reproduce the issue. Various combinations of disabling and re-enabling IGMP on the switch interfaces, vlans, and global config on the Cisco do not seem to reproduce the issue with DLNA broadcast not appearing on the WiFi segments.
So everything is working just fine!

I just need to know if the Netgear APs are blocking multicast from upstream devices in the same IP subnet.
Congratulations. Maybe you are a rare exception to the general rule that the higher the qualifications people claim here – often in a domain far removed from domestic networks – the less they understand.
What are the "Netgear SPs"?
The other forum discussion references an issue with firmware resolved with firmware update.
If you mean the forum discussion you mentioned earlier, as explained, that discussion referred to completely different circumstances. It wasn't even related to the same hardware. Orbi and MR mesh devices are very different. I may not be a network engineer, but I have used both.
Netgear APs = Netgear Nighthawks in AP mode.
Again, all I need to have answered is whether or not the APs are dropping multicast packets from wired to wireless segments.
