When a modern Smart TV refuses to connect to the internet, it often catches you by surprise, especially if you're planning a movie night. The problem could be a software glitch in the operating system itself. webOS, as well as incorrect operation of the router. Owners of the equipment LG It's not uncommon for a device to simply not display available wireless networks in the list or to display an error when attempting to connect.
Before panicking and calling a service center, it's important to run a basic diagnostic on your equipment. Often, the solution lies in simply rebooting the modules or changing static parameters that may have been reset after a router firmware update. Connection stability depends on many factors, including channel loading and physical antenna placement.
In this article, we will examine in detail the algorithms of actions that will help you get your money back. Smart TV We'll cover both the TV's software settings and the router's configuration so you can troubleshoot the issue yourself without calling a technician.
Basic diagnostics and software reset
The first and most effective step is a full system reboot. Many users simply turn off the TV with the remote, putting it into standby mode, but this does not completely restart the operating system. To properly clear accumulated errors, you need to turn off the device using the button on the device, and then unplug the power cord from the socket for 2-3 minutes.
At the same time, you should also reboot your router. Even if the router's indicators are green, errors may have accumulated in its buffer, blocking the distribution of IP addresses to new devices. Turn off the router, wait a minute, and then turn it back on again, allowing the network to fully load.
After turning on the equipment, try to find the network again. If the TV LG If your Wi-Fi connection still isn't detected, check if the wireless module itself is enabled in the settings. Sometimes, after power surges or updates, the Wi-Fi function can be disabled by software. To do this, go to the settings menu and make sure the wireless connection slider is set to "On."
⚠️ Attention: If the problem persists after completely disconnecting from the power supply for 5 minutes, it is most likely not a temporary glitch, but a settings conflict or hardware malfunction of the module.
Checking date, time, and regional settings
One of the most common and subtle reasons for connection failure is a misplaced date and time. Security protocols SSL/TLSNetworks used for data encryption require time synchronization. If the TV's date is set to, say, 2015, but the router's certificate was issued in 2026, the connection will be lost immediately or the network won't even appear in the list.
Please check your date settings manually. Go to Settings → All settings → General → Time and DateMake sure your time zone is correct and the time matches the current time. Ideally, you should enable automatic network synchronization, but if your internet connection is down, you'll have to set the settings manually.
Why does date affect Wi-Fi?
Modern security protocols use certificates with limited validity. If the TV's system time is outside the router's certificate's validity, the security device blocks the connection, considering it potentially unsafe.
It's also worth paying attention to the region. In some models LG Your country selection affects the available frequency ranges and channels. If you move or accidentally change your region in the settings, your TV may no longer detect networks operating on frequencies restricted in that region.
Setting up DNS servers to bypass blocking
Often the TV sees the network, but cannot establish a connection to the servers LG or your internet provider. In this case, manually entering DNS addresses can help. The default addresses assigned by your provider may be unstable or block access to media services.
To change the settings, go to Settings → Network → Wi-Fi connection → AdvancedSelect the "Edit" connection type and find the DNS entry field. Disable automatic mode and enter the addresses of public servers. Google's servers are considered the most reliable (8.8.8.8) or Cloudflare (1.1.1.1).
After entering the information, save the settings and reboot the TV. This procedure often resolves the issue where the network indicator is lit but pages or apps fail to load. Changing DNS It can also speed up the response time of the Smart TV interface.
| DNS provider | Main address | Alternative address | Peculiarities |
|---|---|---|---|
| Google Public DNS | 8.8.8.8 | 8.8.4.4 | High speed, reliability |
| Cloudflare | 1.1.1.1 | 1.0.0.1 | Emphasis on privacy |
| OpenDNS | 208.67.222.222 | 208.67.220.220 | Content filtering |
| Yandex.DNS | 77.88.8.8 | 77.88.8.1 | Local speed in Russia |
2.4 GHz and 5 GHz frequency bands
Modern routers often operate in two bands: 2.4 GHz and 5 GHz. Older or budget TV models LG may only support the 2.4 GHz band. If your router is configured to operate exclusively in 5 GHz mode or hides the 2.4 GHz network, the TV simply won't detect the signal.
Check the specifications of your TV model. If it does not support the standard 802.11ac (Wi-Fi 5), the 5 GHz band is unavailable. In your router settings, you need to make sure the 2.4 GHz network is active and broadcasting. Sometimes, separating the network names (SSIDs) for different frequencies helps to ensure the TV connects to the correct one.
☑️ Checking frequency ranges
Interference is also worth considering. The 2.4 GHz band is heavily congested in apartment buildings, where microwaves and Bluetooth devices are used. If the network is available but extremely slow, try changing the broadcast channel in your router settings from "Auto" to a fixed channel (e.g., 1, 6, or 11).
⚠️ Please note: Router interfaces from different manufacturers (Keenetic, TP-Link, ASUS) vary. If you are unsure of your frequency settings, consult your provider's manual or the router model, as incorrect changes may temporarily disable internet access for all devices in your home.
Reset network settings and update software
If simple methods don't help, try resetting your TV's network settings. This will delete all saved passwords and connection configurations, returning your Wi-Fi module to its original state. To do this, go to Settings → Network → Reset Wi-Fi settings (the path may differ depending on the version webOS).
After the reset, you'll need to re-enter your network password. Make sure you enter it correctly, including capitalization. Often, the problem stems from entering a complex password with symbols.
An equally important step is updating your TV's software. Older firmware versions may contain errors in the wireless module drivers. If possible, connect your TV to the internet via a LAN cable or share your internet connection from your smartphone via a USB modem (if your TV model supports this) to download updates. Then go to Settings → Support → Software Update.
Hardware faults and external adapters
When software methods have been exhausted, it's worth considering the possibility of hardware failure. In televisions LG A separate Wi-Fi module, either on the board or connected via a ribbon cable, is responsible for the wireless connection. Over time, it can fail due to power surges or overheating.
Diagnosing this at home is difficult, but an indirect sign may be the complete absence of any networks within range, even neighboring ones, despite the network being visible and stable on other devices (phones, tablets). The module may also become overheated, leading to constant connection interruptions.
As a temporary or permanent solution, you can use an external USB Wi-Fi adapter. However, not all adapters compatible with TVs LGUsually only original whistles work. LG (WG, AN series) or some models from TP-Link with certain chipsets (e.g., based on the RTL8188). Before purchasing, be sure to check the compatibility list for your specific TV model.
How to check USB adapter compatibility?
The best way is to search for information on the official support website. LG In the "Accessories" section for your model, you can find the adapter. You can also try it at a friend's before buying. There's no universal driver for all USB devices in your TV; it only works with a predefined set of devices.
Is it possible to connect to the Internet via a phone?
Yes, most modern Android smartphones and iPhones support internet sharing via a USB cable. Connect your phone to the TV's USB port, enable "USB tethering" in your phone's settings, and the TV should detect the wired connection, bypassing the built-in Wi-Fi module.
Will a factory reset help?
A full factory reset will erase all your accounts, apps, and settings. This is a last resort. If the built-in Wi-Fi module is physically faulty, a factory reset won't help. But if the problem is a deep software conflict, it might be a lifesaver.
Why does the TV see the network, but says "Not connected"?
This means there's a physical connection to the router, but no access to the global network. Possible causes include an incorrect password, expiration of the ISP's service, a MAC address block in the router settings, or issues with the ISP.
