Doorbell Camera reset button WON’T result in WHITE LIGHT

Seems my good trusty doorbell camera won’t go into the setup mode with the “WHITE” circular light again AFTER I INSTALLED MY NEW UPGRADED WI-Fi using updated network SSID and updated router PASSWORD! I get a “YELLOW” flashing light after I hit the small black reset button albeit by taking doorbell apart in very cold, icy weather outside while trying not to drop the miniature mounting set screw! (

Am buying a back up set screw for future use!)…but not “WHITE” flashing light. I was able to use my new Router on my Indoor SimpliSafe cam but not on this doorbell camera again! Any suggestions, tips, help? Thanks in advance.
