A wired ethernet connection provides more stable, lower-latency streaming than Wi-Fi. Here's what you need to know about connecting a Firestick to ethernet.
Which Firestick Models Support Ethernet?
Of the current Fire TV lineup, only the Fire TV Cube (3rd Generation) natively supports ethernet via an included ethernet adapter. The Fire TV Stick models — including the HD, 4K Plus, and 4K Max — do not have a built-in ethernet port and do not officially support wired connections.
Fire TV Cube Ethernet Setup
The Fire TV Cube includes an ethernet adapter in the box. Connect the adapter to the Cube's USB-C port, plug in the ethernet cable, and the Cube will automatically detect and use the wired connection. Go to Settings > Network to confirm the connection.
Ethernet Options for Firestick Models
While not officially supported, some Firestick models can use USB OTG (On-The-Go) adapters with an ethernet adapter connected. However:
Third-party ethernet adapters for Firestick are not officially supported by Amazon. Results vary significantly, compatibility is not guaranteed, and using them may affect device stability.
Improving Wi-Fi as an Alternative
If ethernet isn't practical, the following can significantly improve your Wi-Fi connection and approach wired performance:
- Use a Wi-Fi 6E compatible model (Fire TV Stick 4K Max or Fire TV Cube) — these offer the fastest wireless performance
- Connect to the 5GHz band on your router
- Position your router close to the TV
- Use the HDMI extender cable to improve the Firestick's antenna position
- Use a Wi-Fi mesh system to improve coverage throughout your home
