A:Answer Hi milton,
Great question! Yes, the Fire TV Cube does support a wired Ethernet connection, so you can bypass Wi-Fi entirely. Here's what you need to know:
The Fire TV Cube (3rd Gen/latest model) includes an Ethernet port built into the power adapter, so you can connect an Ethernet cable directly. However, there's an important distinction regarding connecting directly to a modem versus a router:
Connecting to a modem directly:
It depends on your modem type. If you have a modem/router combo unit (gateway) provided by your ISP, then yes — you can plug the Ethernet cable directly from the Fire TV Cube's adapter into your modem, and it should work since the combo unit handles both functions.
If you have a standalone modem (separate from a router), it typically only provides one IP address to one device. In that case, connecting the Cube directly would work for the Cube, but no other devices in your home would have internet access at the same time.
What we recommend:
If you want to bypass Wi-Fi for a more stable, reliable connection, plug the Ethernet cable from the Cube's adapter into your router (or modem/router combo). This gives the Cube a dedicated wired connection while keeping your other devices online.
One note on speed: The built-in Ethernet adapter supports 10/100 Mbps — which is more than enough for 4K Ultra HD streaming.
We hope this helps! If you have any other questions, feel free to reach out to us at 1-888-280-4331.
