ok yes same here i do notice asus firmware fixing somethings and breaking up others, i dont have wifi camera but yeah its easyier to notice then just gadgets or the phone, but im getting drop outs with the phones and gadgets
I think I found the issue. Don't enable "wifi agile multiband" on any radio your nest cameras might use. I disabled it and seems my cameras are staying connected. I'll monitor overnight. BTW unless you are using the router in a mesh network, I don't think there is any benefit of using the feature anyway.
Over the last week or two I have come across all sorts of settings that might have some influence on what you are seeing.
Can you concentrate on just one of those cameras and let us know what it is doing and how often it does it. Do you have smart connect enabled?
There are settings which determine what the minimum signal strength for a device to stay connect, there are power management frames options that may keep a device from connecting.
I had a device that was trying to connect every 11 seconds but it did not have the updated password.. It seems yours connect for some time then disconnect so is there any time that repeats with that process?
Have you tried moving one of the cameras to a position where you knew the signal strength was sufficient and see if it would stabilize?
Do the cameras come with their own software or do they just use Win 10? The specs say they are WEP, WPA/WPA2 security.
Do they communicate through some device like Alexa?
