Need advise on how to improve my Fire Stick connection

I have an Amazon Fire Stick and I love it, but I always have issues with buffering. It's on WiFi (only option) but my WiFi is great. I have a 4K smart TV that the Fire Stick is plugged into. That can stream Netflix in 4K without ever buffering. Plus my Xbox is wireless on the same tv and it downloads around 30mbs wirelessly. Is the Fire Stick just built that bad?

I guess so, if you haven't got any sort of problems with Netflix 4K or Xbox wireless then it's the stick that got weak wifi adapter - you can try to enter it's network settings and twinker with latency, channels etc.

What I did was change my router channel to 1 instead of Auto. Now it works wonderfully:). I figured it couldn't. hurt to put it here in case someone else has the same problem. Thank you for the suggestions
