Doorbell 2 not retaining connection

Nether my ring spotlight cam and doorbell 2 maintain connect to my wifi. Prior to changing my modern these devices worked flawlessly. I've tried different networks (24. & 5.8), performed a factory reset, disconnected and reconnected, and still no love. When attempting going through the connection steps the doorbell device 'connects' but then it on the main screen, it shows as 'offline,' the spotlight cam does not connect. All other household devices have strong continuous wifi connections.Any help would be appreciated
