Further investigation shows that it has a mac address of 00:00:00:00:00:00. If I Factory Reset it, re-set-up the networking, deactivate the device with Netflix, and re-activate the device with Netflix, it works for a while. But, next time I turn it on, I have to do it again. I would like to return this device for an exchange. How do I do this? Thanks. Our agent will get back to you within 2 business days.
