Owners of old but high-quality models LG Often face a dilemma: the matrix still works perfectly, but there are no built-in smart TV features, and you don't want to run an Ethernet cable from the router across the entire apartment. There is a solution, but it requires understanding how exactly TV interacts with a wireless network. Direct connection via the "Network" menu on such models is impossible without special equipment, as they lack a built-in module. Wi-Fi.
There are several proven ways to bypass this limitation and stream content from mobile devices or computers. You will need to either purchase an external USB adapter, compatible with your model, or use the multimedia capabilities of your home network via the protocol DLNAIn some cases, the only solution is to purchase an external set-top box that will transform any screen into a full-fledged media center.
Before purchasing equipment, you need to accurately determine your device's model and firmware version. This determines the list of supported devices. Wi-Fi modules, as manufacturers often change compatibility even within the same series. Ignoring this step may result in the purchased adapter simply not being detected by the system.
⚠️ Attention: The menu interface and list of supported devices may vary depending on the model year and operating system version. NetCast or earlier versions WebOSAlways check the exact adapter model in the official user manual on the manufacturer's website for your specific TV series.
Checking compatibility and selecting a USB adapter
The most direct way to get wireless internet is to install a special module into a USB port. However, not just any dongle will work. TVs LG They require specific drivers built into the device's firmware, so universal solutions don't work here. You need to find an adapter model that's officially supported by your software version.
The list of compatible devices usually includes products from companies TP-Link, D-Link or ASUS, but only certain revisions. For example, popular models of the series TL-WN721N or TL-WN725N They often appear on compatibility lists, but even these have versions with different chipsets that may not work. You need to search for the exact TV model code on the official support portal.
- 🔍 Find the sticker on the back of the TV with the exact model code (e.g. 42LA620V).
- 📋 Go to the support site and enter this code in the search bar.
- 📥 In the "Support" section, find a list of compatible USB devices or Wi-Fi adapters.
- 🛒 Purchase an adapter of the exact modification specified, paying attention to the hardware platform version.
After purchase, the installation process is simple: insert the adapter into an available port USB (usually labeled as USB IN 1 or USB 2.0). The TV should emit a confirmation beep, and the "Wireless Connection Setup" option should appear in the network settings menu. If this doesn't happen, the drivers for this chipset are missing from the system.
Setting up a wireless connection via the menu
If the adapter is successfully detected, you can proceed to network configuration. Navigating the menu of older models may be unusual compared to modern smartphones, but the logic remains the same. You need to navigate to the section Settings, then select “Network” and go to the “Wireless network (Wi-Fi)” connection type.
The system will start searching for available access points. Select your router's name from the list (SSIDIf the network is hidden, you'll need to manually enter the name and security settings. To enter the password, use the on-screen keyboard controlled by the remote, which can be tedious for long character combinations.
☑️ Setting up a Wi-Fi connection
Choosing the right encryption type is crucial. Most modern routers use the standard WPA2-PSK, which is supported by most TVs. If you have an outdated WEP or the newest WPA3, the TV may not detect the network or refuse to connect. In this case, you'll need to change the router's security settings through its web interface.
⚠️ Attention: When entering your password, be careful with your letter case and language. Even a single character error will result in an endless connection loop, and the TV will report "authorization error" or "no network access."
Using DLNA technology for broadcasting
Even if a full browser or YouTube apps aren't available, you can stream videos, photos, and music from your computer or smartphone using technology DLNA (Digital Living Network Alliance). The TV acts as a renderer, receiving a data stream from the media server over the local network.
To implement this scheme, your computer and TV must be on the same network. On a PC with an operating system Windows You can use the built-in "Streaming Media" feature or third-party software like Plex or Universal Media ServerOn a smartphone, the server function is performed by gallery applications or special players with support Cast.
The algorithm of actions is as follows:
1. Connect both devices to the same Wi-Fi network (TV via adapter, PC via Wi-Fi or cable).
2. On your PC, share the folder with the content or launch the media server.
3. On the remote control LG press the button Input or Smart and select the "DLNA" or "Media Devices" source.
4. Select the file you want to play.
| Parameter | Description | Requirements |
|---|---|---|
| Protocol | DLNA / UPnP | Supported by most LG TVs |
| Video formats | MP4, MKV, AVI | Depends on the codecs in the firmware |
| Network speed | 54 Mbps+ recommended | For HD content without buffering |
| Source | PC, Laptop, Smartphone | Installed server software |
Problems with formats and codecs
One of the main difficulties when using older models LG Without a full-fledged Smart TV, file format support is a problem. Built-in decoders may not be able to handle modern codecs, such as HEVC (H.265) or audio format DTSAs a result, when trying to play, you may see a black screen with working sound or no image at all.
To avoid problems, it is recommended to use universal formats such as H.264 (AVC) for video and AAC or MP3 For audio. Converting files on your computer before transferring them to your TV often solves the problem of image lag. It's also worth paying attention to the file system of your flash drive if you're using local storage.
Why can't the TV see the file via DLNA?
Often, the problem isn't with the network, but with access rights. Make sure your Windows Firewall settings allow access to the private network and that the network profile is set to "Private" and not "Public." Some antivirus programs may also block incoming connections from the media server.
If you use third-party software to organize your media library, make sure it is configured for transcoding. Transcoding — is the process of transcoding video on the fly into a format the TV can understand. This reduces the load on the TV's processor by transferring the processing to a powerful computer.
Alternative: External TV Set-Top Boxes
If fiddling with drivers and adapters seems too complicated, there is a more modern and reliable solution. Buying an external set-top box based on Android TV or any other OS will turn your regular screen into a powerful multimedia device. These gadgets connect via a port. HDMI and have their own Wi-Fi module.
Popular options include devices from Xiaomi (Mi Box/TV Stick), Nvidia Shield or budget models on chips Amlogic And RockchipThey are not subject to TV firmware limitations, as they have their own operating system and are updated independently of the screen model.
- 📺 Connect the set-top box to a free HDMI port.
- 🔌 Power the device from the TV's USB port or a power outlet.
- 📡 Set up Wi-Fi in the set-top box interface (Android/WebOS).
- 🎬 Install any apps from the Google Play Store.
The advantage of this approach is that you get up-to-date information. Smart TV With support for 4K, HDR, and all popular streaming services. The interface will operate significantly faster than the built-in systems found on TVs from ten years ago. Furthermore, the set-top box's remote often supports voice search.
⚠️ Attention: When choosing a set-top box, look for an HDMI port. If you have a very old TV (plasma or LCD) that only has a component or VGA input, you'll need an active signal converter, which may degrade picture quality.
Screen Mirroring
Many users simply want to mirror their smartphone's image to a larger screen. On TVs LG This function is often called Screen Share or MiracastEven without a full-fledged Smart TV, some models support video streaming via Wi-Fi Direct.
To activate, find the "Screen Share" app or similar in the list of signal sources. On an Android smartphone, select "Cast," "Smart View," or "Wireless Projector." The devices must be on the same network, although a direct connection to the router may not be required when using Wi-Fi Direct.
It's worth keeping in mind that image quality and latency depend on signal strength. This method is ideal for viewing photos or presentations, but for fast-paced games, you may experience some delays. lag (delay) between an action on the phone and the image on the screen. Also, make sure that your smartphone isn't in power-saving mode, which can limit Wi-Fi performance.
Diagnosis and solution of common problems
During the setup process, you may encounter various errors. The most common one is "Unable to connect to the network." This can be caused by a weak signal, especially if you are using a USB adapter, which often gets hot and loses connection. Try using USB extension cable, to move the adapter to the best reception area.
Another issue is slow page loading speeds or video buffering. Check the internet speed on other devices. If your router is delivering less than 10-15 Mbps, comfortable viewing of HD content will be difficult. Also, try changing the Wi-Fi channel in your router settings to avoid interference from neighboring networks.
If the module is completely inoperable, try resetting the TV's network settings to factory defaults. Sometimes errors accumulate in the configuration that prevent it from working properly. communication protocolsAfter the reset, you will need to re-enter your Wi-Fi password.
Why doesn't the TV detect my USB Wi-Fi adapter?
Most likely, your adapter model isn't supported by your firmware version. LG TVs don't have universal drivers for all chipsets. Try finding the exact adapter model in the compatibility list on the official website or use an external set-top box.
Can I connect my TV to 5GHz Wi-Fi?
Most older LG models and inexpensive USB adapters only support the 2.4 GHz band. 5 GHz network operation requires a dual-band adapter and corresponding TV support, which is rare on models without a built-in Smart TV.
How to improve Wi-Fi signal reception on TV?
Use a USB extension cable to move the adapter away from the TV case (metal shields the signal). You can also try pointing the adapter toward the router or using an external antenna, if your adapter model supports one.
