Confused about IGMP snooping, benefit on network with Chromecasts?

[binarydad]

I'm curious about the use of "Enable IGMP Snooping" on the wireless pages, and the two "Enable multicast routing (IGMP Proxy)" and "Enable efficient multicast forwarding (IGMP Snooping)" settings under IPTV. Does enabling/configuring any of these yield benefit to a network with about a dozen Chromecast/Alexa devices? If so, is there a proper configuration? All my settings are currently disabled. Thanks.

Those settings are only relevant for (IPTV) traffic being forwarded from the WAN. The only settings that you might want to change if you are having issues are those under Wireless - Professional.

Is there any more info about the wireless settings to adjust to optimize for Chromecasts? Is it just enabling IGMP snooping? Has anyone seen benefit? Thanks.
