Preparing equipment and checking the network
Before you begin setup, you need to make sure your equipment is ready to handle multimedia traffic. The key element here is router, which should support 802.11ac or ax standards to ensure high throughput. If the router is old or located in a far corner of the room, the signal may not be strong enough for streaming video.
If you plan to use screen mirroring, check that your TV is connected to the same network as your smartphone or computer. To do this, go to the settings menu and select the network connections section. In most cases, the system automatically detects available access points.
⚠️ Note: If you are using a dual-band router, make sure that both your TV and phone are connected to the same frequency (for example, both to 5 GHz) to avoid problems with device detection on the local network.
The optimal solution for stationary TVs is to connect via LAN cableIf the wireless signal is unstable, you can use a wireless router. However, if you prefer a wireless solution, make sure there are no thick concrete walls or metal structures between the router and the TV that could block the signal. After checking the physical location of the equipment, you can move on to the software.
Setting up the built-in Wi-Fi module in webOS
operating system webOSThe system used in modern LG models offers an intuitive interface for network management. To begin, press the settings button on the Magic Remote to open the main menu. Select the gear icon in the upper right corner of the screen to access advanced settings.
In the list that opens, find the section All settings → Network → Wi-Fi connectionThe system will offer a list of available wireless networks. Select your network from the list and enter the password using the on-screen keyboard. Once successfully connected, a corresponding icon will appear in the corner of the screen.
If the automatic setup does not work, you can use the button WPS On your router, you can quickly pair it without entering a password. Press this button on your router, then select the WPS option in your TV menu. This is secure and fast, but requires physical access to the router.
☑️ Connection check
It is important to note that some features may require a software update. Go to General → About TV → Check for updatesto ensure you have the latest firmware version installed. This fixes many Wi-Fi connection issues.
Watching IPTV through built-in applications
One of the most popular ways to watch television is through technology. IPTVThere are many programs available in the LG Content Store, such as Peers.TV, ViX or OTT PlayerInstalling such applications allows access to hundreds of channels via the Internet protocol.
After installing the app, you will often need to enter your provider details or download a playlist in the format .m3uThis file contains links to channel streams and can be obtained from your service provider or found in open sources. Data is entered via a virtual keyboard or a dedicated website on your computer.
| Application | Content type | Paid subscription | 4K support |
|---|---|---|---|
| Peers.TV | Broadcast channels | No | Yes |
| VIX | Movies and TV series | Eat | Yes |
| YouTube | Online video | No (Premium) | Yes |
| Netflix | Streaming service | Yes | Yes |
Some providers offer their own apps that can be downloaded directly. In this case, simply enter the login and password provided by your carrier. Image quality in these apps is typically higher than with universal players, as they are optimized for a specific network.
Screen Share
Function Screen Share (or Miracast) allows you to mirror the entire image from your smartphone or tablet to a larger screen. It's ideal for viewing photos, videos from your gallery, or even playing games. The technology works without installing any additional software on the TV, using built-in protocols.
You need to launch the app on your LG TV Screen Share or select the appropriate signal source in the input menu. On an Android device, this feature may be called "Cast," "Smart View," or "Wireless Display." Apple devices use the technology AirPlay 2, which is also supported by new LG models.
The connection process takes a few seconds: select your TV's name from the list of available devices on your smartphone. The image will instantly appear on the screen. Please note that your smartphone must not go into sleep mode during this process, otherwise the streaming will be interrupted.
⚠️ Please note: When streaming heavy video in high resolution, your smartphone may become very hot and the battery will drain faster than usual.
For iPhone and iPad owners, the process is even easier thanks to integration AirPlaySimply press the cast button in any supported video player and select LG TV. Image lag is minimal, allowing you to comfortably watch even fast-paced scenes.
What to do if the phone doesn’t see the TV?
Make sure Bluetooth is enabled on both devices (it's often used for initial discovery). Also, check if the "AP Client Isolation" feature is enabled on the router, which prevents devices from seeing each other on the network.
Using DLNA to play files
Technology DLNA Allows you to play media files stored on your computer or network-attached storage (NAS) directly through your TV. You don't need to transfer files to a flash drive; the PC and TV only need to be on the same network. This is convenient for watching downloaded movies in high bitrates.
On your Windows computer, you need to enable media streaming. Go to "Media Streaming Settings" and allow access for your LG TV. After that, your computer's icon will appear in the "Photos & Videos" menu on your TV.
Navigate the file system using the Magic Remote. You can create playlists, pause, and rewind videos. Popular formats are supported, such as MKV, MP4, AVI.
If the built-in player does not read the file format or there are no subtitles, it is recommended to install a third-party player from the LG Content Store, for example, VLC for LGIt has more powerful codecs and works better with network resources.
Solving buffering and quality issues
Even with a perfect setup, users may encounter issues such as screen blocking or constant loading pauses. Most often, this is due to congestion on the Wi-Fi channel from neighboring routers. In this case, changing the channel in the router settings to a less congested one can help.
It's also worth checking the internet speed directly on the TV. Some LG models have a built-in speed test in the network settings. If the speed is significantly lower than what your provider claims, the router may be unable to handle the load or is too far away.
Resetting your TV's network settings can often help resolve software errors. Go to Settings → General → Factory Reset (or just network settings, if the option is available). This will return the network configuration to its original state.
⚠️ Note: The menu interface and item names may vary slightly depending on the model year and webOS version. Always consult the official user manual for your specific model.
In rare cases, the problem may be with the router itself. Restarting the router by unplugging it for 10-15 seconds can clear the cache and restore a stable connection. If all else fails, consider using a Wi-Fi repeater to boost the signal in the area where the TV is located.
