Short answer: it depends on the exact model. Amazon, Google and Roku each document wired Ethernet for some of their devices, mostly through an adapter, and support and requirements differ between models from the same brand (see the Fire TV and Roku tables).
If you still need to get a cable to the TV in the first place, or your model isn’t covered below, see our guide to wired connection options.
Find your exact model first
“Fire TV Stick” or “Roku stick” isn’t enough to go on. Amazon lists its sticks by name, generation and release year, and Roku lists its devices by model number, so you need those details to match your device to the right entry.
Fire TV Stick
Amazon’s developer specifications give these Ethernet entries for newer Fire TV Stick models:
| Model (as Amazon names it) | Amazon’s Ethernet entry |
|---|---|
| Fire TV Stick 4K (3rd Gen, 2026) | Supported via ethernet adapter |
| Fire TV Stick HD (2026) | Requires Amazon ethernet adapter |
| Fire TV Stick 4K Select (2025) | Requires Amazon ethernet adapter |
| Fire TV Stick 4K Plus (2025) | 10/100 Mbps (with external dongle) |
| Fire TV Stick HD with Alexa Voice Remote (2024) | 10/100 Mbps |
| Fire TV Stick 4K Max (2nd Gen, 2023) | 10/100 Mbps (with external dongle) |
For older sticks, Amazon’s entries read:
| Model (as Amazon names it) | Amazon’s Ethernet entry |
|---|---|
| Fire TV Stick 4K Max (1st Gen, 2021) | 10/100 Mbps (with external dongle) |
| Fire TV Stick (3rd Gen, 2020) | 10/100 Mbps |
| Fire TV Stick Lite (1st Gen, 2020) | 10/100 Mbps |
| Fire TV Stick 4K (1st Gen, 2018) | 10/100 Mbps (with external dongle) |
| Fire TV Stick (2nd Gen, 2016-2019) | 10/100 Mbps (with external adapter) |
| Fire TV Stick Basic Edition (2017) | 10/100 Mbps (with external adapter) |
| Fire TV Stick (1st Gen, 2014) | Not supported |
These tables leave out the Fire TV Stick 4K (2nd Gen, 2023); check its entry, and any model not listed here, in Amazon’s device specifications.
What the entries say, and don’t say:
- For the 2026 Fire TV Stick HD and the 4K Select, Amazon’s entry is “Requires Amazon ethernet adapter”.
- For the 2026 Fire TV Stick 4K, Amazon says Ethernet is supported via an adapter but doesn’t give a speed.
- For the 2024 Fire TV Stick HD with Alexa Voice Remote, the 2020 Fire TV Stick (3rd Gen) and the Fire TV Stick Lite, the entry gives the speed only; unlike other rows, it doesn’t mention an adapter or dongle either way.
- Of the models in these tables, only the original 2014 Fire TV Stick is listed as “Not supported”.
Chromecast and Chromecast with Google TV
Google’s troubleshooting guide says Chromecast and Chromecast with Google TV both support Ethernet but don’t have an Ethernet port, and to use “the Ethernet adapter, sold separately”. It suggests a wired connection as a way to relieve your home Wi-Fi network.
That guide doesn’t give a speed or adapter requirements, and it doesn’t say whether the Google TV Streamer has an Ethernet port, so this page doesn’t cover the Google TV Streamer, even though Google’s guide names it in its title.
Roku
Roku says not all of its devices support a USB Ethernet adapter. Its support article lists these as compatible:
| Device | Model numbers |
|---|---|
| Streaming Stick, Streaming Stick Plus | 3840X, 3830X |
| Express | 3960, 3960RS |
| Express 4K | 3940 |
| Express 4K+ | 3941 |
| Streambar SE | 9104R |
| Streambar | 9102 |
| Streambar Pro | 9101R2 |
| Smart Soundbar | 9101 |
| onn. Roku Smart Soundbar | 9100 |
If your model number isn’t on Roku’s list, Roku’s article doesn’t document it as working with a USB adapter, and this page doesn’t cover it.
What the adapter has to meet
Roku sets out these requirements:
- Speed: 10/100 Mbps only. Roku says gigabit (1000 Mbps) adapters won’t work.
- Chipset: AX8877X or SMSC95XX, which Roku says is usually listed in the adapter’s specifications.
- Plug: Micro USB for the Express and Express 4K, USB-C for the Streaming Stick and Streaming Stick Plus, and USB-A for streambars and soundbars. Roku’s list doesn’t name the plug for the Express 4K+, so check the port on your device.
- Power: on Express models, the adapter needs its own power from a wall outlet. Streambars and soundbars power the adapter themselves. Roku’s power note doesn’t say whether it covers the Express 4K+, and it doesn’t mention power for the Streaming Sticks.
Switching a Roku to wired
Roku’s steps: plug the adapter into the USB port on the back of the Roku device, and connect it to your router with an Ethernet cable. Then press Home, go to Settings > Network > Set up connection and select Wired. Roku says the Wired option only appears when the device recognizes the adapter, so if it’s missing, check the adapter against the requirements above.
