I have not been able to successfully connect a brand new Ring Spotlight Cam Plus to the Wi-Fi- network. Some notes:

Wi-Fi network is made up of 5 X50 routers. I have tried connecting to different routers and all have the same issues

I have had the same issue with 2 brand new Ring Spotlight Cam Plus so can rule out the Ring devices

I have a Ring doorbell and Chime and they connect to the Wi-Fi network and work perfectly

I have tried connecting to the Guest Wireless using 2.4Ghz and same issue

I have tried connecting to a new IOT network and same issue

I have managed to get the Ring devices connected and working as a one off, but as soon as the Ring devices is turned off they are not able to reconnect
