Modern Smart TV We've transformed a regular TV into a powerful multimedia center, capable of playing content from the internet, running streaming services, and displaying photos from personal gadgets. However, for the smart features to work fully LG WebOS NetCast or older versions require a stable internet connection. Users often encounter situations where an Ethernet cable is impossible to install, and the TV's built-in Wi-Fi module is not working properly or is missing altogether. In such cases, it becomes necessary to share the internet connection from another device by creating a local network or using wireless data transfer technologies.
There are several proven ways to establish a wireless connection between the signal source and the screen. You can use your smartphone as access point, configure the router in repeater mode, or use Screen Share features to mirror the image. Each method has its own technical specifications, bandwidth requirements, and menu setup nuances. SettingsUnderstanding these differences will help you choose the best option for your specific equipment model and avoid common synchronization errors.
In this guide, we'll cover all available connection methods in detail, paying special attention to security settings and data transfer parameters. We'll also cover how to properly share Wi-Fi with an LG TV via mobile devices running different operating systems, as well as the use of wired adapters and dedicated dongles. Proper network configuration will ensure smooth, high-definition video playback without lag or buffering.
Using your smartphone as a Wi-Fi hotspot
The most common and fastest way to provide your TV with internet access is to turn your smartphone into a portable router. Modern mobile devices based on Android And iOS allow you to create secure wireless networks that Smart TV It connects like a regular home router. To activate this feature, go to your phone's settings, find the "Access Point" or "Tethering" section, and enable it.
It's important to note that this sharing method uses your mobile data plan, so for viewing heavy 4K content, it's best to have an unlimited data plan or a landline internet connection via your phone. Once enabled, your smartphone's name will appear in the list of available networks on the TV screen. Enter the password displayed in your phone's settings and wait for the connection to be established. WebOS usually automatically detects the network type and configures the necessary IP parameters.
⚠️ Note: Using your smartphone as a router drains the device's battery significantly faster. It is recommended to keep your phone connected to a charger or power bank during the session.
Connection quality directly depends on the network standard your phone supports (3G, 4G, 5G) and the distance to the TV. If the signal is weak, the video may constantly pause to buffer. In the hotspot settings menu on your phone, you can change the frequency range from 2.4 GHz to 5 GHz if both devices support this standard, which will improve performance. data transfer rate.
Setting up a wireless connection via Miracast and Screen Share
Technology MiracastLG's Screen Share feature allows you to not only share the internet but also stream images and audio directly from your smartphone or tablet to your TV. In this case, the TV uses Wi-Fi Direct to create a direct connection with the mobile device, eliminating the need for both devices to be connected to the same wireless router network. This is ideal for sharing photos, playing videos from apps that don't support Chromecast, or presenting presentations.
To start working, press the button on the remote control. Input or select an application Screen Share in the main menu. On a smartphone, the function may be called "Cast," "Smart View" (Samsung), "Projection" (Xiaomi), or "Screen Mirroring" (iOS via AirPlay 2 on new LG models). The devices will find each other automatically, after which a connection confirmation message will appear on the TV screen.
Unlike regular internet sharing, it's not the global network speed that's important here, but the stability of the local channel and low latency. If you plan to stream high-definition content, make sure both devices are within line of sight of each other. Some models LG OLED And NanoCell support simultaneous Wi-Fi Direct operation and connection to a home network, which allows you to use interactive features.
Why might Screen Share not work?
The feature may not activate if the TV is in power saving mode or if the smartphone has aggressive power saving settings that block background Wi-Fi processes. The issue is also often caused by an outdated TV firmware version.
It's worth noting that using Miracast may slow down your smartphone, as its processor and Wi-Fi module are under increased strain from encoding the video stream in real time. For watching online videos, it's best to use built-in apps on your TV, and reserve Screen Share for local content.
Connection via external Wi-Fi adapter and USB
Owners of older LG TVs that don't have a built-in Wi-Fi module can solve the connection issue by using an external USB adapter. However, there's an important caveat: compatibilityLG TVs, like many other manufacturers, only work with specific adapter models, usually those with Ralink chipsets or specific Realtek versions. A standard computer adapter may not be recognized by the system.
The setup process is fairly simple: simply plug a compatible adapter into your TV's USB port, and a "Wi-Fi (USB)" option should appear in the network settings menu. After that, the connection process is the same as before: select your network from the list and enter the password. It's important to use USB 2.0 ports, as some older models may not work correctly with 3.0 (blue) ports for network devices.
| Adapter model | Chipset type | Standards support | Compatibility with WebOS |
|---|---|---|---|
| LG AN-WF100 | proprietary | Wi-Fi Direct, Miracast | Full (official) |
| TP-Link TL-WN725N | Realtek | 802.11n | Partial (requires verification) |
| D-Link DWA-125 | Ralink | 802.11n | High |
| Generic adapters | Various | 802.11ac/ax | Low (rarely work) |
If you're planning to purchase an adapter, be sure to check the list of supported devices on the manufacturer's official website for your specific TV model. Using unsupported equipment will only result in the TV displaying an error message or simply not responding to the device.
Networking via a router and repeater
If the Wi-Fi coverage area does not reach the TV and it is impossible to install a cable, the optimal solution is to use additional equipment to boost the signal. Repeater A repeater receives the signal from the main router and broadcasts it further, allowing you to connect a TV in a remote room. This is the most stable way to distribute Wi-Fi to an LG TV in large apartments or houses with thick walls.
Setting up a repeater is usually done through the device's web interface. Connect it to your computer or smartphone, navigate to the IP address (indicated on the sticker), and select "Repeater" mode. After selecting the primary network and entering the password, the device will create a clone of your network with the same name or with the "_EXT" prefix. Your LG TV will connect to this network just like the primary one.
An alternative is a second router configured in Access Point mode, connected to the main router via cable or wireless bridging (WDS). This approach provides higher performance and connection stability, which is critical for streaming. HDR contentIn this case, the TV will think that it is connected to a regular wired network, although the physical connection is over the air.
☑️ Network readiness check for Smart TV
Troubleshooting connection and stability issues
Even with proper setup, users may encounter a situation where the TV sees the network but doesn't connect, or the connection constantly drops. A common cause is incorrectly configured date and time on the TV. If the system time is out of sync, security certificates won't be verified, and the router will block the connection. Check the time settings in the menu. General → Time and Date and enable automatic synchronization.
Another common issue is a full network settings cache or IP address conflict. In this case, resetting the network settings to factory defaults can help. Go to Settings → Network → Advanced → Edit and select "Disconnect" or "Delete Profile," then try connecting again. You should also try changing the DNS servers in the connection settings to public ones, such as Google's (8.8.8.8) or Cloudflare (1.1.1.1), which often speeds up application response times.
⚠️ Note: Menu interfaces may vary depending on the webOS version (3.0, 4.0, 5.0, 6.0, and above). If you can't find the item you need, use the settings search or refer to the user manual for your specific series.
If your LG TV can't see the 5 GHz network, make sure there are no regional restrictions in your router settings. Some TV models released for certain markets may not support channels used in other regions. Switching your router to automatic channel selection or setting it to a channel in the 36-48 range often resolves the visibility issue.
Alternative Methods: HDMI and Ethernet Adapters
When wireless methods prove unstable or the connection speed is slow, it's worth considering hybrid options. One such option is using USB-to-Ethernet adapters. If your TV has a USB port but no LAN port (or it's occupied), a special adapter allows you to connect a network cable directly. This ensures maximum stability, which is necessary for watching video with bitrates above 100 Mbps.
Another option is to use output devices such as Chromecast, Apple TV, or Android boxes that connect to the HDMI port. These devices have their own, often more powerful, Wi-Fi modules and operating systems. You can distribute Wi-Fi to your LG TV indirectly by connecting the internet directly to the set-top box. This also frees up resources on the TV itself and speeds up the interface.
For iPhone and MacBook owners, AirPlay 2 technology, built into many new LG models, is a popular choice. It allows not only for streaming content but also for using the TV as an external sound card or a second screen. This functionality requires both devices to be on the same subnet, which is easily accomplished with any modern router.
Why won't my LG TV connect to 5GHz Wi-Fi?
Many older and even some mid-range LG TVs only support the 2.4 GHz band. If your router broadcasts networks with the same name (Smart Connect), the TV may attempt to connect to the 5 GHz band and lose connection due to a weak signal. Solution: Separate the networks in your router settings by giving them different names (e.g., Home_2G and Home_5G), and connect the TV to the 2.4 GHz network.
How do I reset network settings on an LG TV?
Go to the settings menu (gear icon), select "All settings" → "General" → "Network." Find "Wi-Fi Connection" or "Network list," select your network, and click "Delete" or "Forget." Afterward, perform a full reset of the TV by unplugging it for 10 seconds, and then try connecting again.
Is it possible to share Wi-Fi from an LG TV to other devices?
The LG TV itself typically acts as a client (receiver) and cannot distribute the internet connection received via the LAN port to other devices via Wi-Fi (the TV does not have a repeater function). However, it can act as a signal source for Screen Share (Wi-Fi Direct), but other devices will not have internet access through this channel, only the ability to stream images.
