You have a Nighthawk AX8 router

Apple TV 4K hub

None of my HomeKit Circle View rooms (3 of them) answered in a few days. I even tried to disconnect and reconnect one of them and it says it can’t find the accessory.

I reset my router

I reset Apple TV and tried to unplug it

MyQ garage door does not respond

LG CX9 OLED does not respond (without Apple TV, only using the built-in interface)

And AirPrint stopped working and I had to connect it to my router via Ethernet and now I can AirPrint it

However, all my Lutron switches work perfectly. Maybe bc bridge is connected to the router via Ethernet?

And my Siri commands to turn on the lights or Apple TV works

I’m at a loss. No idea what to do.
