Check if my TCL Roku TV model has Ethernet port

By /

You can check if your TCL Roku TV model has an Ethernet port by combining physical inspection, model‑name research, and TCL’s own guidance. Here’s how to do it step by step so you know whether you can connect it via Ethernet or must rely on Wi‑Fi.

1. Physically inspect the back of the TV

TCL TV Ethernet port

  • Turn the TV around and look at the rear panel where the input ports are located.

  • Look for a rectangular RJ‑45 socket labeled Ethernet or with an icon that looks like a small network cable.

  • If you see a standard LAN‑style port with a small clip‑connector, your model does have an Ethernet port; if there is only HDMI, USB, and coaxial, it is Wi‑Fi‑only.

This is the fastest way to tell: if the physical port is there and matches Ethernet‑style jacks on other devices, the TV can accept a wired cable.

2. Read the exact model number from the TV

  • On the back of the TV, below the brand label, you’ll see a model tag such as 55S423, 65S455, 43S305, etc.

  • Write down the full model name (including “S‑series” number and any suffix like “‑CA”) exactly as printed.

Once you have the model, you can cross‑check TCL’s specs.

3. Check TCL’s official specs or retailer page

Using the model number you wrote down:

  • Search for "TCL [your model] Roku TV" in a search engine (for example, “TCL 55S423 Roku TV”).

  • Open the TCL product page or a major retailer page (Walmart, Best Buy, etc.) and look under Specifications or Ports for Ethernet or LAN.

TCL’s own support text notes that Ethernet is available only on TCL Roku 4K TV models (larger 4‑, 5‑, and 6‑series TVs), whereas many smaller or older TCL Roku TVs provide Wi‑Fi only and do not include a LAN port.

4. Confirm via TCL support wording

  • TCL’s “How to connect your TCL Roku TV to the internet” page explicitly says you can connect via Wi‑Fi (all TCL Roku TVs) or Ethernet (if your TV model includes an Ethernet/LAN port), and specifically notes that Ethernet is only on TCL Roku 4K models.

  • If your TV is not a 4K TCL Roku TV, odds are it lacks an Ethernet port and is strictly Wi‑Fi‑based, even if a similar‑size TCL Android TV has one.

So if your model is something like 32S321 or another non‑4K TCL Roku, reviews and TCL‑Q&A pages usually state that it has no Ethernet port and connects only via Wi‑Fi.

5. If there really is no Ethernet port

  • Some TCL Roku owners with Wi‑Fi‑only models still want wired‑like stability and use a USB‑to‑Ethernet adapter, but TCL never officially supports this, and success depends on the TV’s internal firmware and USB‑Ethernet profile.

  • If your model is clearly Wi‑Fi‑only, the most reliable path is to keep using Wi‑Fi or consider a different TV model/brand with a LAN port if wired Ethernet is a must‑have feature for your Nairobi‑style broadband setup.

In short: look at the back of the TV, match your model number to TCL’s specs, and rely on the rule that wired Ethernet normally appears only on TCL Roku 4K‑series sets; anything older or smaller usually has no Ethernet and uses only Wi‑Fi.
