IGMP Snooping in AP Mode
I'm running in AP mode and experience an IGMP storm when connecting the LAN cable to one of the non-main devices.
[home network]->switch->M9 = This will cause a storm of IMGP packages to any device connected to the same switch. Rending the whole network section unusable.
[home network]->M9->switch = No storm occurs.
I found this old tread https://community.tp-link.com/us/home/forum/topic/168554 which says it should be possible to turn on IGMP snooping in AP mode through the web interface (not the app) under System - System Parameters - IGMP Feature - Enable IGMP.
But logging in to neither the the main device nor the one with the issue show me any IGMP options, the only available parameter is WAN Unicast.
