I'm not sure what you mean by "Google Home" (app, speaker, Google/Nest Wifi), TV provider (TV service, internet provider, smartTV), or what the issue is you are having that they say you need the IGMP to be checked.
Can you please provide more detail? I have some solutions but I need more context to narrow things down.
@PatrickP_Viking, thanks for the trying to clarify this.
@VatozLocos , we appreciate your interest however, we don't have any news to share about IGMP feature for Google Wifi networks. We're always looking for ways to improve and we'll take it as feedback.
I also suggest that you send feedback by following this link. Let me know if you have other questions or concerns, otherwise I’ll be locking this thread after 24 hours.
