How to connect an LG TV to the internet via cable: instructions with photos and tips

Wired TV connection LG to the internet is a reliable way to get a stable signal without lag, especially if your router is far from your device or walls are blocking the Wi-Fi signal. Despite the name "wired" Wi-Fi", we are talking about the classic Ethernet connection (via an RJ-45 cable), which many people mistakenly call "wired Wi-Fi." In this article, we'll discuss how to properly connect LG Smart TV With a router, what settings to check, and what to do if the internet isn't working.

The main advantage of this method is the absence of interference and high speed, which is critical for watching videos in 4K or online games. However, not all models LG They support direct wired connections; in some cases, an adapter will be required. We'll cover both options, as well as common mistakes users make during setup.

If you've previously tried connecting via Wi-Fi and experienced connection drops or slow speeds, switching to a cable may solve the problem. However, it's important to consider the following: cable length, protocol version (Fast Ethernet vs Gigabit Ethernet) and even the placement of electrical outlets in the room. Below is a step-by-step guide with photos and optimization tips.

Which LG TVs support wired connections?

Not all models LG Smart TV equipped with built-in Ethernet portTo check for its presence, inspect the back panel of the TV: the socket for the network cable is usually located next to the HDMI ports and marked as LAN or a picture of a computer with a cable. If there is no port, you will need USB-Ethernet adapter (we will talk about it below).

Here is the list of episodes LG, which are most often equipped with a wired interface:

• 📺 LG OLED (series C, G, E, W, Z - since 2016)
• 📺 LG NanoCell (SM, NANO85 series and above)
• 📺 LG QNED (all models)
• 📺 LG UHD 4K (UN, UK, UP series – since 2018)

Budget models (for example, LG 24TQ510S or old episodes LB/LJ) often lack a LAN port. In this case, use an adapter, but be aware that it may limit the speed to 100 Mbps (even if the router supports 1 Gbps).

What you need to connect

Before you begin, prepare the following ingredients:

• 🔌 Network cable (Cat 5e or higher). The length depends on the distance between the TV and the router. For 4K content recommended Cat 6.
• 📡 Router with a free LAN port. Make sure it is enabled. DHCP server (usually activated by default).
• ⚡ USB-Ethernet adapter (if the TV doesn't have a LAN port). Models with a chip are suitable. ASIX AX88179 (For example, TP-Link UE300).
• 🔧 Screwdriver (may be needed for securing cable in baseboard or wall).

If you are using an adapter, check its compatibility with webOS (operating system LG). Some cheap Chinese devices are not recognized by the TV. A list of supported adapters can be found at LG's official website (section "Accessories" for your model).

Step-by-step instructions: connecting via LAN port

If your TV has a built-in connector LAN, follow these steps:

1. Turn off your TV and router (press the power button or unplug them). This will prevent any potential problems during the initial connection.

2. Connect one end of the network cable to the LAN port on the back of the TV and the other end to an available port on the router. Ports are usually numbered (LAN1, LAN2 etc.).

3. Turn on the router and wait until it boots up completely (the indicators on the front panel should be steadily lit).

4. Turn on your TV and go to the settings menu: press the button Settings (⚙️) on the remote → select All settings → Net → Connecting to the network.

5. From the list of available connections, select Wired network (Ethernet)The TV will automatically receive an IP address from the router (if enabled). DHCP).

6. Wait for the message "Connected to the Internet"If an error occurs, check the cable or reboot the equipment.

If your TV doesn't recognize the network, try setting the IP address manually:

1. In the network menu, select IP settings → Manually.
2. Please enter an IP address from your local network range (e.g. 192.168.1.100, if the router has an address 192.168.1.1).
3. In the field Gateway Enter the router IP (usually 192.168.1.1 or 192.168.0.1).
4. IN DNS please indicate 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare).

What to do if the TV doesn’t see the cable?

Check the TV port for damage (gently move the cable—if contact is lost, the connector inside the port may have come loose). Also, try a different cable or port on the router.

Connecting via a USB-Ethernet adapter

If yours LG Smart TV If you don't have a LAN port, use an external adapter. The process is a bit more complicated, but still doable:

1. Buy a compatible adapter (recommended) TP-Link UE300 or Ugreen USB 3.0 to Ethernet).

2. Connect the adapter to the USB port of the TV (it is better to use the port USB 3.0, if there is one, it is usually blue).

3. Connect the adapter to the router with a network cable.

4. Turn on your TV and go to Settings → Network → Network connection.

5. Select Wired network (USB adapter)If the option does not appear, the adapter is not compatible.

Important: Adapters based on the Realtek RTL8153 chip may not work with 2019–2020 LG TVs due to a lack of drivers in webOS. Before purchasing, check reviews or the compatibility list on the manufacturer's website.

After successful connection, check your internet speed: go to Settings → Network → Network StatusIf the speed is lower 50 Mbps, try:

• 🔄 Reconnect the adapter.
• 🔌 Use a different USB port on your TV.
• 📶 Reboot the router.

Setting up a router for a stable connection

Even if the TV is connected to the network, the speed may be slow due to incorrect router settings. Here's what to check:

To change settings:

1. Open the router's web interface (enter in the browser 192.168.1.1 or 192.168.0.1).
2. Log in (default logins: admin/admin or admin/password).
3. Go to the section LAN or Local area network.
4. Set the parameters according to the table above and save the changes.

For further optimization:

• 🔒 Reserve an IP address for your TV in the settings DHCP (so that the address does not change upon reboot).
• 📊 Turn on IGMP Proxy (if you watch IPTV).
• 🔄 Update your router firmware to the latest version.

Common errors and their solutions

If the Internet connection on your TV isn't working or is unstable, check these points:

⚠️ Attention: If the TV shows a message "The cable is not connected.", but the cable is physically inserted, the problem may be in a damaged connector RJ-45Try crimping the cable again or replace it.

If the TV connects but apps don't open (for example, YouTube or Netflix), check:

• 🔍 Date and time on the TV (incorrect settings may block SSL connections).
• 🌍 Region in the settings (some services are not available in certain countries).
• 🔄 Application cache (clean it in Settings → General → Storage).

⚠️ Attention: On TVs LG From 2021 to 2026, the network menu may not have the manual IP configuration option. In this case, use automatic mode or update the firmware.

How to check internet speed on an LG TV

To make sure your wired connection is working properly, measure the speed:

1. Open the menu Settings → Network → Network Status.
2. Select Checking your internet speed.
3. Wait for the test to complete. Normal values:
   • 📶 100+ Mbps - enough for 4K and online games.
   • 📶 50–100 Mbps - enough for Full HD.
   • 📶 <20 Mbps - some slowdowns are possible.

If the speed is lower than expected:

• 🔌 Check if anyone else on the network is using your traffic (torrents, downloads).
• 📡 Restart your router and TV.
• 🔧 Make sure that the cable is not routed near sources of interference (for example, near power lines) 220V).

For a more accurate test, use the app Speedtest by Ookla (available in LG Content Store). Run it and compare the results with data on other devices (for example, a laptop).

FAQ: Frequently asked questions about wired connections

Is it possible to use a cable longer than 30 meters?

Technically Ethernet supports length up to 100 meters without amplifiers, but in practice after 50–60 meters Packet loss may occur. For long distances, use:

• 🔄 Switch (signal amplifier) ​​in the middle of the cable.
• 📡 Powerline adapters (signal transmission via electrical wiring).

Why doesn't the TV detect the USB-Ethernet adapter?

The reasons may be as follows:

• The adapter is not compatible with webOS (check the list of supported devices on the website LG).
• The TV's USB port is not supplying enough power (try connecting the adapter via USB hub with external power supply).
• Port USB 2.0 limits speed (use USB 3.0, if any).

Solution: Try a different adapter or update your TV's firmware.
