Amazon’s new Ethernet adapter highlights a major Fire TV Stick limitation
Source: Android Authority
TL;DR
- Amazon’s new Ethernet adapter officially supports Gigabit speeds.
- The adapter is “Gigabit,” but the Fire TV Stick’s USB 2.0 port limits real‑world speeds to roughly 300 Mbps – 480 Mbps.
New Fire TV Stick HD and USB‑C Port
Amazon has updated its Fire TV Stick, replacing the old micro‑USB connector with a USB‑C port on the second‑generation Fire TV Stick HD. This change suggests the possibility of faster wired networking.
USB‑C Ethernet Adapter
Alongside the new stick, Amazon released a matching USB‑C Ethernet adapter. According to AFTVnews, the product specifications list “up to 480 Mbps” as the maximum speed.
Why the Speed Is Limited
- The Fire TV Stick HD uses a USB 2.0 controller internally, despite the USB‑C connector.
- USB 2.0 caps at 480 Mbps, which is the theoretical maximum for the port.
- In practice, users can expect ≈ 350 Mbps throughput—better than the old 100 Mbps micro‑USB adapter but far from true Gigabit Ethernet (1 Gbps).
Reason Behind the “Gigabit” Adapter
Amazon likely introduced a Gigabit‑rated adapter to future‑proof the accessory. When a Fire TV device with a genuine USB 3.x port is released, the same adapter could operate at full Gigabit speeds. For now, the adapter’s performance is constrained by the stick’s USB 2.0 hardware.
Compatibility
- Works with: New Fire TV Stick HD (USB‑C).
- Does NOT work with: Older Fire TV models (micro‑USB), Fire TV Cube 3, Fire TV Stick 4K Max, and other higher‑end Fire TV devices.
Practical Impact
Most streaming scenarios (e.g., 4K video) require only ≈ 25 Mbps, so the limited bandwidth isn’t a problem for typical media consumption. However, users who run Plex servers, perform local network file transfers, or need higher sustained throughput may find the 300‑480 Mbps ceiling disappointing.
