I have a nest camera and it goes offline every 10 mins. I went back to Screwfix and they changed the camera for a new one. It still happens. The Asus router is about 2m away from it so I dont think it is that. Are these just problematic?
I used to have BT whole home. Broadband (the black discs) and mine would do that a couple of times a week and would not connect until I rebooted the router…
Since buying an Orbi they have been ultra reliable - so it is possibly your router.
