Greetings @Jenkins5
Welcome to the Roku Community and thanks for posting regarding connectivity issues with your Roku Smart Home Camera.
Have you tried moving the Roku Smart Home Camera that you have connectivity issues closer to your wireless router without the user of the extender to see if you are experiencing the same connectivity issues? If you aren't experiencing an issue with the Roku Smart Home Camera next to the wireless router, this would indicate that there may be a wireless network connectivity issue possibly related to your wireless network extender.
Please keep us posted what you find out and we will be more than happy to continue assisting you.
Thanks,
Danny
