1080p dome camera will not read QR code and connect to Wifi

I have 3 1080p dome cameras that I have reset numerous times but all 3 will not read the QR code and connect to WiFi network. At this point, they are bricks.

I have looked for new firmware but can not find it.

What was the solution.? I am having issues with my wireless. I have two others that I have used for years with no issues and this one will not connect - it goes to wifi connection and then times out after 2 plus minutes.
