Using Wi-Fi Direct and Screen Share
Technology Wi-Fi Direct Allows you to connect mobile devices directly to your TV, without using a router. This is useful if you need to quickly stream photos or videos from your smartphone but your home Wi-Fi network is temporarily unavailable. This feature is usually located in the "Show" section of the TV menu. Net -> Wi-Fi Direct.
To activate the mode, enable the feature on your TV, after which it will begin broadcasting a signal. Your TV's name will appear in the list of available Wi-Fi networks on your smartphone (e.g., LG_webOS_TV_XXX). Connect to it by entering the password displayed on the TV screen.
- 📱 Open a broadcasting app (such as YouTube or Gallery) on your smartphone.
- 📺 Select the output device (LG TV) from the list of available ones.
- 🎬 Enjoy content on the big screen without lag.
It's worth noting that when using Wi-Fi Direct, the internet on the connected smartphone may stop working, as the Wi-Fi module switches to a direct connection to the TV. For a fully functional Smart TV with access to online services, a traditional connection via a router is still recommended.
What is the difference between Wi-Fi Direct and Miracast?
Wi-Fi Direct creates a direct connection between devices, while Miracast is a video streaming protocol that can use Wi-Fi Direct to establish a communication channel. Simply put, Direct is the "pipe," and Miracast is what flows through it.
Diagnostics and solutions (of common problems)
Even with the correct settings, users may encounter connection errors. One of the most common issues is the TV not detecting the network or displaying "No internet connection," even though the router is working. This is often due to frequency band incompatibility: older LG models only support 2.4 GHz, while newer routers may hide this network by operating only in the 5 GHz band.
Another cause of failures are errors in the DNS servers. Try in the network settings (item Change or Advanced Settings) register static DNS addresses, for example, from Google (8.8.8.8 And 8.8.4.4). This often helps if pages are loading slowly or applications are not launching.
| Symptom | Probable cause | Solution |
|---|---|---|
| Gray Wi-Fi icon | The module is disabled or the driver is faulty. | Restarting the TV (completely, with unplugging) |
| "Incorrect password" | Input error or encryption type change | Checking the layout and changing the security standard on the router |
| Constant breaks | Weak signal or interference | Bringing the router closer, using a repeater |
| No internet access | Problem with DNS or ISP | Changing DNS, checking the provider's cable |
If your TV stops connecting after a firmware update, it's possible your network settings have become corrupted. In this case, resetting the network to factory settings in the settings menu or completely resetting the TV (deleting all data) can help.
Optimizing connection speed and stability
Viewing 4K HDR content requires high bandwidth. If you notice a drop in image quality or long buffering times, it's worth optimizing your router. Make sure your TV is connected to the appropriate range. 5 GHz, which is less congested and provides higher data transfer speeds.
The router's location is crucial. Don't hide it in a niche under the TV stand—a metal TV screen and heavy furniture can block the signal. The optimal location is high up, in the center of the room, or closer to the TV, but still maintaining a safe distance.
⚠️ Note: Menu interfaces and item names may vary depending on the firmware version and regional TV model. If you don't find an exact match, search for synonyms or consult the official instructions on the manufacturer's website.
It's also worth checking if there's a speed limit (QoS) in your router settings for certain devices. Make sure that's true for your Smart TV sufficient traffic priority is allocated, especially if other users are downloading files on the network at the same time.
Alternative ways to connect to the network
If a wireless connection is unstable or impossible due to room design, a wired connection via LAN cable is always an option. This is the most reliable way to ensure maximum speed and freedom from interference. Simply connect the port LAN on the router and port LAN IN on the TV with an Ethernet cable.
Another option is to use a USB Wi-Fi adapter if the TV's built-in module is faulty or doesn't support the required standard. However, LG strictly regulates the list of compatible adapters, and most standard adapters won't work. You'll need to look for original models, such as AN-WF500 or AN-WF100.
- 🔌 LAN cable: guarantees stability and maximum speed.
- 📡 USB adapter: a solution for replacing a broken built-in module.
- 📱 Sharing from a phone: an emergency option via a USB modem or access point.
As a last resort, you can use your smartphone as a USB modem. Connect your phone to the TV's USB port (if the model supports Ethernet over USB or modems) and enable the corresponding feature in Android settings. This will allow you to access the internet via your mobile data.
