Hi. I'm all WiFi with my home network. I'm told my Homekit Hub (Apple TV 4k box) keeps disconnecting at random times for random durations due to mDNS/Multicast/IPTV setting issues. In search of best settings related to Apple Homekit Hub issues like mine. Just tried these seven steps, but no change in results:

1. Navigate to the “Network” and then “IPTV” section while still under the “Advanced” tab.
2. Click the box to enable “IGMP Proxy”
3. Under the IGMP Version drop down menu select “V3”
4. Click the box to “Enable IPTV”
5. Set LAN 1 and LAN 2 to “Internet”
6. Set LAN 3 and LAN 4 to “IPTV”
7. Click the “Save” button
