I am going to provide my input in case it helps anyone who may be in my situation. I am not an IT expert. I have two Circle View cameras and a doorbell that is hardwired. The doorbell has not caused me any problems. I used to have an old 2015 Apple router unit. When I first installed these cameras and doorbell two years ago, everything worked flawlessly through the home kit app. Recordings were never missed. Nothing ever went offline. Then I bought a brand new Orbi Mesh system (RBRE960) with the router and two satellites. We were starting to get a lot of connected devices and I thought it would be helpful. That's when these cameras stopped being awesome.
They would constantly go offline and recordings were random and rare with any motion. I spent hours and hours researching the problem and ultimately, I gave up. This week, I had tech support at my home for other issues and I brought up my problems. He asked me where my router and satellites were I showed him. He said I think they are too close together and they are confusing your devices. So, at his advice, I disconnected both satellites and ran just the Orbi router for the day/night. The Circle View cameras worked flawlessly. They did not go offline and they recorded all motions as directed. I was surprised that one Orbi router by itself covered full bars in my entire 2,600 SF home except for one room. I set up both satellites, one in that room and another in the garage, all of them pretty far apart. And so far the cameras are working flawlessly.
If you have a mesh WiFi system and your Circle View cameras are not working as they should, consider disconnecting your satellites and testing them with just your router, and if it works, try setting up your satellites as far apart as possible in your home. I would say mine are probably 60-70 feet apart, with one in the basement and the other in the garage, and the router in my main living room under my TV.
