Good idea, but remember I was more talking about wireless interference than device count as the potential issue. Wireless problems can be either dead simple to find and fix, or take a room full of experts and the resources of NASA 
Right. But this should address the concept that there are too many devices on the router.
Depends on whether the apple airport thing has its own DHCP server & whether it’s used
The cameras are still pulling their IPs from the ASUS router assigning it as a static one, yet the cameras have been reliable since this afternoon, which is longer than every before. Maybe I did have “too many” devices on the ASUS, but i’m still convinced the Wyze cams are maybe too sensitive to network blips.
Hopefully they keep working connected to a secondary router.
And SD cards, and low power on USB cords, etc.
In my house it’s my Visio Soundbar that seems to be sensitive to power blips the most. Followed by my Alexa enabled wall clock. (Yes I love gadgets) however NONE of my gadgets except for my Router seem to react well to power brownouts or “flickers” that we have now and again. Go figure. About the only things that don’t recover from full power failures is my Hue Hub and my cheap Linux computer.
