I think I need to be more specific. The TV is located in my RV in an RV resort. The " FREE" wifi is flakey at best and will not support streaming. I can get to an alternate wifi service where I can use my NETFLIX account to download movies to the SM-T280 tablet which I can then take back to my RV. The description of Chromecast indicates the need for a wifi conection. I am trying to find a means of showing the movie stored on my tablet on the TV. I connected the tablet to the TV using the mico USB cord that came with the tablet but I am unable to get the TV to recognise the tablet. If I load the chromecast app onto the tablet, will it allow me to do what I am trying to do - with no active wifi connection.
