Roon RAAT and "An audio file is loading slowly"

[K4680]

Hi, just a thought someone has ever tried Mulicast / IGMP on the router on or off. If so, has it affected the traffic load?
"IGMP (Internet Group Management Protocol) Snooping".

Router Specific Settings (Roon)
Some routers have settings that can cause interference with Roon's communication to endpoints and Remote devices. Below are some of the common configuration changes that have been required for some routers to function properly with Roon.

Netgear Orbi Routers
If you’re making use of an Orbi router, we recommend unchecking Disable IGMP Proxying in your router’s settings. This setting can interfere with the ability for Roon Remotes to connect to the Roon Core.

Technicolor Routers
We've seen that some technicolor routers cause Roon to have difficulties communicating to networked endpoints. This can be resolved by adding exceptions for Roon and RAATServer to the router's IPv6 firewall settings.

Motorola Routers
Some Motorola routers have a setting called Energy Efficient Ethernet. This setting has previously been known to cause occasional dropouts during playback to networked endpoints. Disabling this setting can help alleviate these dropouts.

FRITZ OS 7
The FRITZ OS 7 update includes a feature called "Software Packet Acceleration" that can cause issues with remote connectivity. We recommend disabling this setting from the FRITZ GUI.

ASUS Routers
We recommend enabling "Enable Multicast Routing" option in settings.

Netgear R7000
We recommend disabling the "Enable Smart Connect" setting.

Synology 1600
We recommend enabling "IGMP Proxying" and/or "IGMP Snooping"
