How to bypass LG TV 100 Mbps Ethernet limit with USB adapter

By /

You cannot truly “remove” the built‑in 100 Mbps Ethernet limit on an LG TV, but you can bypass it by using a USB‑to‑Gigabit Ethernet adapter plugged into one of the TV’s USB ports. This gives you a wired, higher‑bandwidth path that behaves like multi‑hundred‑Mbps or near‑1‑Gbps Ethernet, depending on the USB version and adapter quality.

1. Check if your LG TV supports USB Ethernet

Before buying anything:

  • Look up your exact LG model (for example, OLED55C2, 43UQ7500, etc.) and search for “USB‑to‑Ethernet adapter LG TV” + your model number.

  • Confirm that the TV’s USB port is USB 2.0 or USB 3.0; adapters work best on USB 3.0 but can still push 300–400 Mbps on USB 2.0‑only models.

If your model is listed as successfully using a USB‑to‑Ethernet adapter (e.g., LG C8, C1, C2 owners), that is a good sign it will work for you.

2. Choose the right USB‑to‑Gigabit adapter

  • Buy a USB 3.0‑to‑Gigabit Ethernet adapter (labels “10/100/1000 Mbps”) from a reputable brand like Cable Matters, Anker, TP‑Link, or similar.

  • Avoid cheap “USB‑to‑Ethernet” sticks that don’t specify Gigabit or 1000 Mbps; they may still be capped at 100 Mbps.

Make sure the adapter is plug‑and‑play and known to work on LG‑style webOS TVs (forums and YouTube are good for checking this).

3. Connect the adapter and configure

  1. Physically connect

    • Plug the USB‑to‑Ethernet adapter into one of the TV’s USB ports.

    • Connect an Ethernet cable from the adapter to your router or switch.

  2. Let the TV recognize the link

    • Turn the TV on; most modern LG TVs will detect the new Ethernet interface automatically and negotiate a speed higher than the built‑in 100‑Mbps LAN.

    • In Settings → Network, the TV should now show an active Ethernet connection using the USB adapter.

  3. Speed‑test to confirm

    • Use a speed‑test app on the TV or streaming‑app statistics (Netflix / YouTube “Stats for NERDS”) to see if your wired speed now climbs to 300–400 Mbps (USB 2.0) or closer to 1 Gbps (USB 3.0) rather than the old ~100 Mbps cap.

If the result is clearly higher, you have effectively bypassed the 100‑Mbps built‑in Ethernet limit.

4. Practical limits and caveats

  • USB 2.0 ports on older LG sets still only give roughly 300–400 Mbps over USB‑to‑Ethernet—better than 100 Mbps, but not true 1 Gbps.

  • Compatibility is model‑specific: some LG TVs refuse to recognize certain USB Ethernet adapters, so check community reports for your exact model before purchase.

  • This is a workaround, not a guarantee: LG does not officially support these adapters, but in many cases it is the only way to exceed the 100‑Mbps hard‑cap without using Wi‑Fi.

For LG TV owners in Nairobi or similar setups who need high‑bitrate local streaming (4K rips, Plex, Emby, etc.), a supported USB‑to‑Gigabit Ethernet adapter is the most practical way to bypass the 100‑Mbps Ethernet limit and get a stable, higher‑speed wired connection.
