Modern Smart TV It turns a regular screen into a multimedia center, but without internet access, it loses up to 90% of its functionality. Users often encounter a situation where a recently purchased TV LG It doesn't detect the home network or requires complex manual configuration. This could be due to either router issues or software glitches within the webOS operating system itself.
Properly setting up a wireless connection allows you to stream content from mobile devices, use online cinemas, and install apps. The connection process doesn't require in-depth knowledge of networking technologies, but understanding key parameters such as DNS and signal frequency, significantly simplifies the task. Below, we'll cover all setup steps, from preparing the equipment to troubleshooting common errors.
Connection stability directly impacts the quality of video playback, especially when streaming in 4K resolution. If the router is located far away or behind thick walls, the signal may weaken, causing buffering. In such cases, it's important to carefully position the equipment or use additional signal boosters.
Equipment preparation and compatibility testing
Before you begin setup, make sure your router is working properly and is distributing internet to other devices, such as smartphones or laptops. TVs LG Support Wi-Fi 802.11 a/b/g/n/ac standards, allowing them to operate in the 2.4 GHz and 5 GHz bands. However, older models may not support the secure protocol. WPA3, which is enabled by default in new routers.
Check if the wireless module is enabled in the TV itself. In some models, it may be disabled by software or require an external adapter if the built-in one is faulty. For diagnostics, you can try connecting the device to the network via LAN cable; if the wired connection works, the problem lies in the Wi-Fi module or its settings.
⚠️ Note: If your router broadcasts networks with the same names (SSIDs) for both 2.4 GHz and 5 GHz frequencies, your TV may automatically switch between them, sometimes causing disconnects. For stable operation, it's best to temporarily separate the network names in your router settings.
- 📡 Make sure the router is turned on and the indicators are green.
- 📱 Check the internet connection on a smartphone connected to the same network.
- 📺 Find out the model of your LG TV (on the sticker on the back or in the menu).
- 🔑 Prepare your Wi-Fi network password in advance so you don't have to search for it during setup.
Basic setup via the webOS menu
The connection process in modern models with a shell webOS It's unified and takes less than a minute. You'll need a Magic Remote or a standard remote with arrows. First, you need to access the main settings menu, which is usually accessed by pressing the gear button or the Home.
After going to the settings section, select the item Net (Network). The system will prompt you to select the connection type; click on Wi-Fi ConnectionThe TV will scan the airwaves and after a few seconds, display a list of available wireless networks. Find your home network name in the list and tap it.
A virtual keyboard will appear on the screen. Enter your password, being careful about the case of letters and numbers. Once entered, press the button. ConnectIf the information is correct, the TV will receive an IP address from the router and establish a connection. A notification in the corner of the screen will indicate a successful connection.
☑️ Connection checklist
Manual configuration of IP and DNS addresses
In cases where automatic retrieval of settings (DHCP) doesn't work, requiring manual configuration. This often happens due to IP address conflicts or specific router security settings. You need to go to Settings → Network → Wi-Fi Connection → Advanced Wi-Fi Settings.
Uncheck the box Automatically (Auto Setting). Fields for manual entry will open. The IP address must differ from the gateway (router) address by only the last digit, and must be on the same subnet. For example, if the router has the address 192.168.1.1, the TV can be assigned 192.168.1.55.
| Parameter | Example of meaning | Description |
|---|---|---|
| IP Address | 192.168.1.125 | Unique address of the TV on the network |
| Subnet Mask | 255.255.255.0 | Subnet mask (usually default) |
| Gateway | 192.168.1.1 | Your router's address |
| DNS Server | 8.8.8.8 | Domain Name Server (Google) |
Pay special attention to the fields DNS ServerIf your ISP blocks some services or your router doesn't process requests correctly, replace the default DNS with Google's public DNS (8.8.8.8) or Cloudflare (1.1.1.1) solves the problem of no internet connection when the connection is working.
Using Wi-Fi Direct and Screen Share
Technology Wi-Fi Direct Allows you to connect mobile devices directly to your TV, bypassing the router. This is convenient for quickly transferring photos or videos from your phone, but it doesn't provide full access to internet services on the TV. To activate, go to the menu. Network → Wi-Fi Direct and turn on the function.
The TV will begin broadcasting a signal, which can be found in the list of available networks on your smartphone. Once paired, the devices form a local network. However, to use apps like YouTube or Netflix on the TV itself, a connection to the global network via a router is still required.
Function Screen Share Miracast also uses a direct connection for screen mirroring. If you plan to use your TV as a monitor for a laptop or phone, make sure both devices support the Miracast standard. The quality of transmission in this mode depends on the strength of the TV's Wi-Fi module.
⚠️ Please note: When using Wi-Fi Direct, data transfer speeds may be lower than via a router, especially when streaming high-definition video. To view online content, use a classic connection via a hotspot.
Diagnosing and troubleshooting connection problems
If your TV displays "No network connection" or "Server error," you'll need to run diagnostics. There's a built-in tool in the network settings menu. Network Diagnosis (Network Diagnostics). Run it to have the system automatically check for the presence of a cable (if used), the connection status to the router, and internet access.
A common cause of problems is an incorrect date and time. If the TV's time settings are incorrect, website security certificates won't work, and the browser or apps won't be able to connect to the server. Check this item: General → Time and Date and enable network synchronization.
You should also try resetting your network settings to factory defaults. This will delete all saved passwords and IP configurations. After resetting, try connecting again. If the problem persists, it's possible the DNS cache is full or a firmware update is needed.
- 🔄 Perform a full reset of network settings in the TV menu.
- 📅 Check and set the correct date and time manually.
- 📡 Reboot your router by unplugging it for 30 seconds.
- 🔌 Try connecting to a different Wi-Fi network (for example, from your phone) to test the module.
Hidden Causes of Wi-Fi Problems
Often, the problem lies with the router's broadcast channel. If neighboring routers are operating on the same channel, interference will occur. Try changing the channel in your router settings to 1, 6, or 11 for 2.4 GHz, or select a clear channel for 5 GHz.
Firmware update and factory reset
Outdated software is one of the main reasons for unstable Wi-Fi module operation. LG regularly releases updates that improve compatibility with new routers and encryption protocols. You can check for updates in the section Support → Software Update.
If automatic updates via Wi-Fi are not possible due to connection issues, you can download the firmware file from the official website to your computer, copy it to a USB drive (in the root folder), and insert it into the TV's port. The system will automatically detect the file and prompt you to update.
As a last resort, when nothing helps, a full reset is performed (Factory Reset). This will reset your TV to its factory settings. Keep in mind that you'll need to reconfigure all channels, inputs, and service accounts afterward.
Why doesn't my LG TV see the Wi-Fi network?
The most common cause is incompatibility of security standards (WPA3 vs. WPA2) or the router only operating in 5 GHz mode if the TV is older. The TV's Wi-Fi module could also be physically damaged.
How to find out the IP address of a TV?
Go to the menu Settings → Network → Wi-Fi Connection → Advanced Wi-Fi SettingsThe window that opens will display the current IP address, subnet mask, and gateway.
Is it possible to connect a TV via a USB Wi-Fi adapter?
LG officially supports only its own proprietary adapters (such as the AN-WF500), which are now rarely available for purchase. Third-party adapters generally don't work without reflashing the system kernel.
What to do if the password is accepted, but there is no internet?
Check your date and time settings, try setting a static DNS (8.8.8.8) or resetting your network settings. Also, make sure your router isn't using MAC address filtering.
