Modern Smart TV from the company LG have become full-fledged multimedia centers, requiring constant internet access to stream movies, use apps, and update systems. However, users often encounter difficulties when initially setting up a wireless connection. This may be due to interface features. WebOS or NetCast, as well as with the technical nuances of the router's operation.
In this article, we will examine in detail the process of activating the module. Wi-FiWe'll examine the differences between models from different years and offer effective solutions for common issues. Proper setup will ensure stable data transfer and high image quality when viewing online 4K content.
Before moving on to software settings, you need to make sure that your equipment is ready for work. Wireless module LG TVs usually have a built-in USB port, but some older models may require an external USB adapter. Make sure your router is turned on and broadcasting a signal.
Checking compatibility and preparing equipment
The first step is to identify your device model. Menu settings in WebOS 3.0, WebOS 4.0 and newer versions may differ significantly from the interface of older systems NetCastYou can find information about the model on the sticker on the back of the case or in the section Settings → About → Product Information.
It's also important to understand the technical limitations. Most modern TVs support the standard. 802.11ac (Wi-Fi 5) and operate in two bands: 2.4 GHz and 5 GHz. The 5 GHz band provides higher speeds but has a shorter range. If the router is located far away, it's better to use the 2.4 GHz frequency.
If you have an older model, manufactured before 2012, it may not have a built-in Wi-Fi module. In such cases, you'll need to purchase a special adapter. LG Wi-Fi Adapter (usually the AN-WF100 or similar model), which plugs into a USB port. Without this device, wireless connection will be unavailable.
Step-by-step instructions for WebOS TVs
Interface WebOS This is used in the vast majority of modern LG TVs. The setup process is standardized, but the names of the steps may vary slightly depending on the firmware version. To begin, take the remote control and press the gear button or the Settings.
The Quick Settings panel will open. At the bottom of the screen, find and select All settings (often indicated by three dots or a gear with the word Advanced). Go to the section Net or NetworkThe switch is located here. Wi-Fi, which must be switched to the "On" position.

If the network is hidden, select Add a hidden network and enter the name (SSID) manually.
☑️ WebOS Setup Checklist
Setting up Wi-Fi on older models (NetCast)
In TVs with an operating system NetCast The menu logic is structured differently. There's no single quick settings panel; all controls are handled through the main menu. Press the button Smart or Home on the remote control, then go to the section Settings.
In the menu that opens, find the section NetYou will be asked to select a connection type. Select Wireless (Wi-Fi)The system will begin searching for available access points. This process may take up to 30 seconds.
Unlike newer models, manual IP address configuration may be required if automatic acquisition (DHCP) fails. Usually, selecting the mode AutomaticallyIf the TV requires a MAC address for filtering on the router, it can be found in the same menu in the section Wi-Fi settings.
⚠️ Note: Older models may have less sensitive Wi-Fi. If the signal is weak, try moving the router closer to the TV or using a Wi-Fi repeater to boost the signal.
Troubleshooting network connectivity and visibility issues
A common problem users encounter is a TV that doesn't detect the network or refuses to connect, displaying an error. One of the most common causes is incompatibility of encryption standards or frequency bands. The router can only broadcast the network in [unspecified] mode. 802.11n or ac, while TV expects a mixed mode.
It's also worth checking your date and time settings. If the TV's time is incorrect, security certificates won't work, and connecting to secure networks will become impossible. Set the date and time in the section to the correct date. General → Time and Date.
Why does the TV see the network but not connect?
Often, the cause is an incorrect password (check the keyboard layout and capitalization) or MAC address filtering enabled on the router. It's also possible that the router's client list is full.
If all else fails, try resetting your network settings. This will delete all saved passwords and configurations, returning the communication module to factory settings. After this, you'll need to repeat the connection procedure.
Table of typical errors and ways to eliminate them
To quickly diagnose problems, use the table below. It contains the most likely causes of failures and solutions.
| Error Code/Type | Probable cause | Solution method |
|---|---|---|
| No connection to the server | DNS issues | Manually enter DNS 8.8.8.8 in the network settings. |
| Incorrect password | Input error or password change | Delete the network and re-enter the password, checking the case |
| Network not found | 5GHz band or hidden SSID | Enable 2.4 GHz broadcasting on your router or add the network manually |
| Limited connection | IP address conflict | Restart your router and TV, reset your network settings |
Using Wi-Fi Direct and Mobile Hotspot
In addition to connecting to a home network, LG TVs support technology Wi-Fi DirectIt allows you to transfer photos and videos from your smartphone to your TV without having to connect both devices to the same router. This is convenient if your home internet connection is temporarily down.
To activate, go to Settings → Network → Wi-Fi DirectThe device name and possibly a confirmation code will appear on the screen. On your smartphone, select the TV from the list of available devices and enter the code. The connection is established.
Another option is to share your internet connection from your phone. If you don't have wired internet, enable tethering mode on your smartphone. Access pointThe TV will see the phone as a regular Wi-Fi router. However, keep in mind that streaming video uses a lot of data.
⚠️ Please note: When using mobile internet on your Smart TV, monitor your data usage. Watching a movie in HD can use up to 3 GB of data per session.
Reset network settings and update firmware
If a software glitch prevents you from turning on Wi-Fi or saving settings, a hard reset will help. In the menu All settings → General → Reset to factory settings Select the reset option. Be careful: this will delete all installed apps and accounts.
After the reset, be sure to check for system updates. Manufacturers regularly release patches that improve compatibility with new routers. Go to About → Software Update → Check for Updates.
We recommend using automatic updates. If your TV can't connect to the internet to download the firmware, you can download the file from the official LG website to your computer, transfer it to a USB drive, and update it manually via the USB port.

Why can't my LG TV see my 5GHz Wi-Fi?
Many older and some budget LG TV models are equipped with Wi-Fi modules that only operate in the 2.4 GHz band. They physically cannot "see" the 5 GHz network. Solution: Configure separate network names (SSIDs) on your router or combine them into a single network that supports both standards, but ensure the router is broadcasting a 2.4 GHz signal.
Is it possible to connect an LG TV to Wi-Fi without a remote?
No, not using standard methods. The settings menu is closed. However, if the TV was previously paired with the LG ThinQ app on your smartphone and is on the same network (or via Wi-Fi Direct), you can try controlling the settings via your phone. Universal remotes with an IR port or connecting a USB keyboard (this doesn't work in all menus) also work.
What should I do if the Wi-Fi button in the menu is grayed out and inactive?
This indicates that the Wi-Fi module is disabled at the hardware level (rare) or, more often, the module driver is not loaded due to a system crash. Try completely disconnecting the TV (unplugging it) for 2-3 minutes, then turning it on again. If that doesn't help, a factory reset or firmware update is required.
