SO, with the Firestick for example, we still need separate WIFI, or if we USB to the TV (Yes, we have Smart TV) then the WIFI on the Laptop serves as the downloading device and pushes content to Firestick or USB?
What about Android phone, which we have unlimited data, any WIFI either the Firestick or USB connection to the TV makes it function? And as a general rule, you watch it but can't download it at home and watch it on the road, for example.
We have HDMI cord as well ... it runs from Cable Box to TV at home.
Basically, if I understand it: Prime Video >>> WIFI >>> Firestick or USB >>> Smart TV -- and must be live feed (or some series will download) but generally live feed while you watch movies.
