Use Ethernet connection on TCL Roku TV instead of Wi-Fi

By /

Using a wired Ethernet connection on a TCL Roku TV is the simplest way to bypass flaky Wi‑Fi and avoid error codes like 014, especially if your model has a built‑in Ethernet port. Wired networking gives you a stable, low‑latency path to the router, ideal for 4K streaming, live sports, and large downloads on TCL 4K‑series sets. Below is a clear, step‑by‑step guide you can follow regardless of whether you are in Nairobi, Mombasa, or another home‑broadband environment.

1. Check if your TCL Roku TV has an Ethernet port

  • TCL Roku 4K‑series TVs (most 50‑inch and above) usually include a LAN/Ethernet port on the back. TCL’s own support notes that Ethernet is available on TCL Roku 4K TVs, while smaller or older TCL Roku models may be Wi‑Fi‑only.

  • If your TV does not have a LAN port, you can still get a wired‑like connection via a USB‑to‑Gigabit Ethernet adapter (for example, on some 32‑inch TCL Roku sets), but this is model‑specific and optional.

If your TV has a visible RJ45 Ethernet socket on the back, you are ready to use a wired connection.

2. Physically connect the Ethernet cable

Follow these physical steps first:

  1. Connect one end of an Ethernet cable to your router or modem

    • Use any LAN port on the router where other devices already work.

  2. Connect the other end to the TV’s Ethernet port

    • Plug the cable into the Ethernet (LAN) port on the back of the TCL Roku TV.

Once the cable is in place, the TV will usually detect the wired link immediately, but you still need to tell the software to use it.

3. Switch the TV to “Wired” mode in the menu

Even with the cable plugged in, the TV may still default to Wi‑Fi until you toggle the connection type.

  • Press the Home button on your TCL Roku remote.

  • Go to Settings → Network → Set up connection.

  • Choose Wired (Ethernet) instead of Wireless; the TV will then verify the connection automatically.

If the verification is successful, the TV skips straight to the next setup step (for example, linking your Roku account), and apps like Netflix, YouTube, and Showmax will now use the wired link instead of Wi‑Fi.

4. Confirm the wired connection is active

To make sure the TV is actually using Ethernet:

  • Go to Settings → Network → Network status (or a similar info page).

  • Check that the connection type shows Wired or Ethernet, not Wireless.

  • You can also unplug the Ethernet cable; if the TV suddenly loses internet or shows an error, the active link was indeed over Ethernet.

In a Nairobi‑type flat, running a Cat 5e or Cat 6 Ethernet cable from the router in the living room or study to the TV often gives noticeably smoother 4K streaming and eliminates Wi‑Fi‑related error codes such as 014.

5. Optional: keep Wi‑Fi disabled to avoid confusion

If the TV has a Wired option that works, you can improve reliability by:

  • Turning off Wi‑Fi on the TV:

    • Settings → Network → Wi‑Fi → select Turn Wi‑Fi Off or similar.

  • This stops the TV from trying to fall back to Wi‑Fi during a router restart or Wi‑Fi glitch.

If you later want to reconnect to Wi‑Fi (for example, while moving the TV or testing a new router setup), you can re‑enable Wi‑Fi in the same menu and switch back to Wireless in the Set up connection screen.

For most TCL Roku TV owners in Kenya, switching from Wi‑Fi to Ethernet is the most straightforward way to eliminate connection‑related error codes, prevent buffering, and keep streaming stable without needing router‑side DNS tweaks or adapter‑workarounds.
