Modern Smart TV They transform a regular screen into a multimedia center, providing access to online movies, games, and web surfing. However, full functionality of all these functions is impossible without a stable internet connection. Owners of this South Korean brand's technology often wonder how to set it up. LG TV to work through a router without using extra wires.

The connection process may vary depending on the operating system installed, whether it is webOS or older versions of the NetCast platform. Incorrectly configured network settings often result in DNS errors or complete inaccessibility to content, even if the password is entered correctly. In this article, we'll cover all setup steps in detail, as well as troubleshooting common connection issues.

First, make sure your router is working properly and is transmitting a signal, and that your TV is in a strong reception area. If your device supports dual-band, it's preferable to use the frequency 5 GHz For high-definition video transmission without lag. This will ensure maximum data transfer speed and streaming stability.

Equipment preparation and compatibility testing

Before proceeding with software settings, you need to ensure your equipment is technically ready. Not all TV models come with a built-in wireless module, although it's standard in modern models. Older devices may require a separate USB adapter, which must be strictly compatible with the specific model. Smart TV.

Check your device's specifications on the manufacturer's official website or in the manual. If there's no built-in module and purchasing an adapter isn't possible, your only option is a wired connection via a LAN port or using wireless technology. Wi-Fi Direct to broadcast content from a mobile device.

• 📺 Make sure your TV model supports Smart TV technology and has a built-in Wi-Fi module.
• 📡 Check the router's functionality: are the indicators lit and is the internet available on other devices?
• 🔌 When using an external adapter, make sure it is inserted into the correct USB port (usually labeled as D IN or Wi-Fi).

⚠️ Warning: Using non-original USB adapters may result in unstable system operation or complete failure of the module to recognize the network.

It's also important to consider the distance between the router and the TV. Walls, especially load-bearing ones, and household appliances can significantly weaken the signal. If the signal is weak, even entering the correct password won't guarantee stable operation of online services.

Step-by-step instructions: connecting via the settings menu

The primary method for activating the network is through the operating system menu. The interface may vary slightly depending on the version. webOS, but the logic of actions remains the same. You will need a remote control equipped with the function Magic Remote, which will greatly simplify navigation through the items.

Press the settings button on the remote control (gear icon) or the button Home to open the main menu. In the interface that opens, find the gear icon in the upper right corner of the screen, which controls all system settings. Go to the section responsible for network connections.

In the list of available networks that opens, find the name of your router (SSIDIf the network is hidden, select "Add a hidden network" and enter the name manually. After selecting the network, the system will prompt you for a security password, which you must enter using the on-screen keyboard.

Please pay attention to the case-sensitive nature of the password, as the Wi-Fi security system is sensitive to this parameter. Once the password is successfully entered, the TV will attempt to establish a connection, which may take anywhere from a few seconds to a minute. If successful, a notification will appear, along with a connection icon in the corner of the screen.

⚠️ Note: The menu interface may be updated by the manufacturer. If you don't find an exact match, look for similar names in the "Network" or "Connection" section.

If the connection is successful, it's recommended to immediately test your browser or any online movie service. This will ensure that internet traffic is actually being transmitted, and not just a local link to the router.

Using Wi-Fi Direct to cast

Technology Wi-Fi Direct Allows you to connect mobile devices to your TV directly, without using your home router. This is especially useful if your main internet connection is congested or your router is located far from your viewing location. In this mode, the TV automatically creates an access point.

To activate this feature, go to the network settings menu and select Wi-Fi DirectThe network name broadcast by the TV and the connection password will appear on the screen. This information must be entered in the Wi-Fi settings on your smartphone or tablet.

Once the devices are paired, you can stream photos, videos, and music directly from your mobile device to the big screen. The quality of data transmission in this mode depends on the power of the TV module and the distance between the devices.

• 📲 Open the Wi-Fi Direct menu on your TV and note the network name displayed.
• 🔗 Connect your smartphone to this network using the password from the TV screen.
• 🎬 Launch the content on your phone and select the casting function (Cast/Miracast/AirPlay).

It's worth noting that when an active Wi-Fi Direct connection is active, the internet on the connected smartphone may stop working because the channel is busy transmitting a media stream to the screen. This is normal protocol behavior and does not require user intervention.

Why might Wi-Fi Direct not work?

This feature may not be available if the TV is already connected to the main Wi-Fi network. Some models require disconnecting from the router to activate a direct connection. Also, make sure location services are enabled on your mobile device, as this is a requirement for Android to search for nearby devices.

Troubleshooting DNS and IP Address Settings

A common problem for users is when the TV detects the network but has no internet access. This is often due to incorrect settings. DNS servers, which the device automatically receives from the provider. In such cases, manually entering the addresses helps.

In the network connections menu, select "Advanced Settings" or "Wi-Fi Settings." Find the "Settings Mode" option and switch it from "Auto" to "Manual." Here, you'll only need to change the DNS field, leaving the IP address and gateway unchanged unless they conflict with your network.

After entering the new values, save the settings and reboot the TV. This often resolves issues with connecting to the update server or apps not launching. If the issue persists, try cloning the MAC address of a computer that is successfully connected to the network.

⚠️ Important: When manually setting an IP address, make sure the number you select is not already occupied by another device on the network. Otherwise, an address conflict will occur and the Internet will be lost for both devices.

Sometimes ISPs block new devices from connecting based on their MAC address. In this case, you may need to call technical support to register the device or configure the router to bridge mode.

Setting up a wireless connection via WPS

To simplify the connection procedure, many routers and TVs support the technology WPS (Wi-Fi Protected Setup). It allows you to connect devices without entering a password, simply by pressing the corresponding button. This is convenient if you have a complex password or an inconvenient remote control.

In the TV's network settings menu, select "WPS." You'll be prompted to press the WPS button on the router within 120 seconds. The physical button may be located on the back of the router or a virtual button in the device's web interface.

After pressing the button, the TV automatically receives all the necessary encryption keys and establishes a connection. This method uses the same security protocol. WPA2, as well as a standard connection, so it is considered safe enough for home use.

• 🔘 Find the WPS button on the router body (often combined with the Reset button, be careful).
• ⏱️ Run the WPS search in the LG TV menu.
• ✅ Wait for confirmation of a successful connection on the screen.

Please note that some modern routers have WPS disabled by default for security reasons. In this case, you can only enable it through the router's admin panel by logging in from a computer.

Diagnostics and software updates

If none of these methods help, the problem may be due to outdated TV firmware. Manufacturers regularly release updates that fix network module bugs and improve compatibility with new hardware. Checking the firmware version is an important diagnostic step.

Go to the "General" or "Support" section in Settings and select "Software Update." If the TV is connected to the internet, it will automatically check for a new version. If the internet is unavailable, you can update it using a USB drive by downloading the file from the official website.

It's also worth checking the date and time on your TV. An incorrect system clock can cause security certificate errors, causing secure websites and apps to stop working, even with internet access.

⚠️ Caution: Do not unplug the TV during the software update. Interrupting the process of writing data to the flash memory may cause irreversible damage to the system.

After updating, network settings are often reset, so you'll have to reconnect. This is normal practice and ensures the latest network drivers are applied.

What to do if the TV does not see any networks?

Try completely powering off the router and TV for 5-10 minutes. Then power on the router first, wait until it fully boots up, and only then turn on the TV. In some cases, resetting the network settings to factory defaults in the TV menu helps.
