Fire Stick keeps buffering while you're watching

Buffering on your Fire Stick is because the WiFi signal is weak or your internet speed is too slow. Move the Fire Stick closer to your router, or plug it in with an Ethernet cable if possible. If you're watching 4K, try HD instead — it needs less internet speed.

Your Fire Stick streams video over the internet, and buffering happens when the connection is too slow or unstable to keep up with the video quality. The fastest fix is moving the Fire Stick closer to your router so the WiFi signal is stronger. If that doesn't work, check your internet speed — you need at least 5 Mbps for HD and 15 Mbps for 4K. If your speed is fine, something else on your network is using the bandwidth.
