Netflix streaming question! (Break from Trump vs. ____)

Netflix | 10/23/17 | Me, Myself, & I

I am hoping that some of our techie FReepers could give me some guidance on this annoying issue. I have a Samsung "smart" TV which is a couple of years old, which I use exclusively to watch Netflix movies ( I don't watch TV and have not for at least 35 years. But I enjoy watching family fare movies). It is not the latest and greatest TV with all the cutting edge stuff. I see "1080" appear in a box when it first comes on, if that helps.

I have a cable internet modem with its own wi-fi hotspot. I use that, teamed with an Amazon Fire TV stick, to stream Netflix. Virtually every time I watch, the movie stops to buffer and I have to wait until the percents mount up to 99, then the movie starts again. Annoying! If this doesn't happen, then I get an error message necessitating unplugging the TV and Amazon dongle, waiting 10 minutes, then replugging both in. Annoying!

Since the Netflix movies play fine on my iMac, which is directly connected by cable with no intermediary needed, it seems that the Amazon Fire TV stick cannot handle the streaming. Netflix tech reps suggested I replace it with a Roku "box". I think the "box" means the Roku Premiere+ model. Is that the solution for a 1080 kind of TV? Or would the Roku stick be better than the Amazon stick and be sufficient to eliminate these annoying problems?

I thank in advance anyone who is up on their streaming tech who can bring clarity to this situation, because I am confused.
