I originally bought a firestick because I was told that the android operating system on my tv wasn't very good. After about a year I started getting issues with buffering, so I bought this ethernet adapter. Just installed it tonight. So far works well. Note to anyone buying this. It will NOT work for a 1st generation firestick. My firestick is 2nd generation. My firestick on the main floor is 1st generation. If it continues to buffer, I will probably pick up a Roku streaming stick.
