Recent trouble connecting my exterior Ring cameras to wifi

My exterior Ring floodlight camera has been working great since installed in 2021. Recently the camera would not stay connected to wifi. I worked with Ring tech support that resulted in buying a new camera. I installed the new camera, but with the same problem as the old camera. Could not connect to wifi. Has there been other customers with problems connecting exterior cameras to wifi? Has there been any new deployed wifi systems that can interfere with wifi signals? Does Xfinity mobile interfere with wifi signals?

I have also installed wifi signal extender to boost signal. This did work for a few months. The extender does not help now.

My Ring interior cameras work well inside my home.

Any help would be greatly appreciated.
