Motion detection not working

I have (3) Wyze Cams. They all used to work just fine. But motion detection has not been working for at least a week on 2 of the cams and not at all on any of them right now

A few days ago I did mess with my wifi settings in my router (I set my 2.4ghz and 5ghz bands to use the same SSID. Today I changed it back to separate names)

2 of the cams had trouble connecting anyway so I reset them. I have all 3 cams set to detect motion all day and nothing is happening. I’m sitting in the room with one of them and nothing is being recorded.

I have unplugged the cams and, as I said, reset 2 of them. I deleted and re-added them. Still no motion events being recorded.
