Mac mini causing Apple TV renaming and iPhone Wi-Fi issues

Hi everyone, Just got a new Mac Mini, and from the moment I added it to my home Netgear Nighthawk Wifi7 router network, every Apple device has been acting weird.

The Mac Mini itself and all 4 of my AppleTVs are constantly renaming their devices with (2), (3). (1451), etc throughout the day. Seeing some reports that this is a Bonjour issue with the Mac.

No. I only am connected via wired Ethernet connection, not wifi (so the double IP issue isn't causing it).

Also, my family's iPhones will not connect to the router that my Mac Mini is wired into. They login in to the wifi signal, but immediately drop it, then try again, then drop it again. Rinse. Repeat for about 3 more times.

Any ideas?

Your router may be having an issue with the newest implementation of "Private Wi-Fi addresses":

Use private Wi-Fi addresses on Apple devices - Apple Support

This is a very important privacy feature when on networks that you do not manage or trust but can have side effects on a local network that you manage. You can however disable it for your home network. Refer to the article to do so.

Yes, In understand that your Mac is connected via Ethernet, but it's possible that due to things like Continuity and Sidecar, and your router not knowing what the hostname or Bonjour names go with a given MAC or IP, could cause massive confusion on your LAN.
