The situation when the beloved Smart TV suddenly stops seeing the home network or refuses to connect to the Internet, a familiar problem to many technology owners LGInstead of launching online movie theaters or YouTube, users see a "No network connection" error or a blinking search indicator. This is especially frustrating when the router is working properly, and smartphones and laptops connect to the internet without any issues.
The causes may lie in software glitches within the TV itself, incorrect router settings, or even the actions of the ISP. Often, a simple reboot resolves the issue, but in some cases, more in-depth adjustments to the settings are required. DNS or a change in encryption standards.
In this article, we'll examine all possible failure scenarios in detail and offer a step-by-step solution. You'll learn how to correctly diagnose the source of the problem and restore access to your digital services without calling a technician.
Basic diagnostics and initial checks
Before delving into complex settings, it is necessary to rule out basic failures. Often LG Smart TV The Wi-Fi connection fails due to a simple freeze in the wireless module. In this case, a full hardware reboot helps.
Turn off the TV using the remote control, then unplug it for 2-3 minutes. At the same time, reboot the router by disconnecting its power. After turning on the router, wait until the network is fully loaded before turning on the TV. This allows you to clear the network service cache.
It's also worth checking that "Airplane Mode" isn't enabled in the TV menu. This completely blocks wireless modules. Make sure the system date and time are set correctly, as security certificates may not be validated if they are out of sync.
⚠️ Attention: If after a reboot the TV stops seeing all networks, including neighboring ones, there is a high probability of a hardware failure in the Wi-Fi module inside the TV itself.
Check the internet connection on other devices in the same room. If the signal is weak, try moving the router closer to the TV or removing any physical obstructions. Metal structures and mirrors can significantly block the signal.
Problems with date, time and region
One of the most common and non-obvious reasons why LG cannot connect to servers, the date is invalid. Security protocols SSL/TLSThe time zones used for secure connections require precise time alignment. If the TV shows the year 2015 but it's actually 2026, the connection will be lost immediately.
To fix this, go to the settings menu. The path usually looks like this: Settings → All settings → General → Time and dateDisable automatic synchronization via network (since there is no network) and set the current values manually.
Also check your device's region. Some services and network settings may be blocked if the TV's region doesn't match the region of your account or provider. Changing the region may require a system reboot.
Manually Configuring DNS and IP Addresses
If automatically obtaining addresses doesn't work, the problem may be with the router's or ISP's DHCP server. In this case, a common solution is to assign static DNS addresses. This often helps when the TV "sees" the network but displays "No internet connection."
Go to Settings → Network → Wi-Fi connection → Advanced Wi-Fi SettingsFind the "Edit" or "Advanced" option. In the DNS server field, enter the public addresses from Google or Yandex. They are more stable than standard ISP addresses.
Popular addresses to enter:
- 🌐 Google DNS Primary:
8.8.8.8 - 🌐 Google DNS Secondary:
8.8.4.4 - 🇬🇧 Yandex DNS:
77.88.8.8 - 🔒 Cloudflare:
1.1.1.1
After entering the information, be sure to click "Connect" or "OK." The TV will recheck the connection with the new settings. In most cases, this resolves content access issues.
| Parameter | Automatically | Manually (Recommended) | Purpose |
|---|---|---|---|
| IP address | Get a car | 192.168.1.X | Device ID on the network |
| Mask | Get a car | 255.255.255.0 | Network sizing |
| Gateway | Get a car | 192.168.1.1 | Router address |

Conflicts of frequencies and encryption standards
Modern routers often operate in two ranges: 2.4 GHz and 5 GHz. Older TV models LG may not support the 5 GHz frequency or encryption standard WPA3If the router is configured to operate only in the new standard, the TV simply won't see the network or won't be able to log in.
It's recommended to access your router settings (usually via 192.168.0.1 or 192.168.1.1 in a browser) and check your wireless network mode. It's best to set it to mixed mode. 802.11 b/g/n for the 2.4 GHz range.
Also try changing the security type from WPA3 to WPA2-PSK (AES)This is the most compatible standard, guaranteed to work with all household appliances. Avoid using older WEP standards, as they are insecure and can be blocked by modern applications.
⚠️ Attention: Router interfaces are constantly being updated. The exact names of the options may vary depending on your router model (Keenetic, TP-Link, Asus). Please consult your router's manual.
If the problem persists, try separating the networks into different names (SSIDs). Name the 2.4 GHz network, for example, "Home_24," and the 5 GHz network, "Home_5." Connect your TV to the 2.4 GHz network, as it has better penetration through walls.
Why is 2.4 GHz better for TV?
The 2.4 GHz band has a lower data transfer rate, but penetrates obstacles much better and has a longer range. Its speed is more than sufficient for streaming 4K video (up to 25 Mbps), while 5 GHz can lose signal in distant rooms.
Firmware update and factory reset
TV software is a complex system that can accumulate errors over time. If none of the above helps, check for updates. Sometimes manufacturers release patches specifically to fix Wi-Fi module compatibility issues.
Since Wi-Fi isn't working, there are two ways to update. The first is via an Ethernet (LAN) cable. Connect the TV directly to the router with a wire, go to Settings → Support → Software Update and run the scan.
The second method is updating from a USB drive. You'll need a computer. Download the latest firmware for your model from the official website. LG, unzip the archive, and place the files on the root of a USB flash drive (formatted FAT32). Insert the USB into the powered-off TV, turn it on, and follow the on-screen instructions.
☑️ USB update algorithm
If that doesn't help, there's a more radical option: a factory reset. This will delete all your accounts and channel settings, but return the system to its default state. Path: Settings → General → Factory Reset.
Wi-Fi module hardware failure
When software methods are exhausted, one has to talk about hardware. In televisions LG A Wi-Fi module can fail due to power surges, lightning storms, or simply a defective device. Symptoms include: the module won't turn on, the menu is grayed out, or the TV constantly displays "Unable to connect" even when connected directly to the router.
In some models, the module is a separate board that can be replaced. In others, it is soldered to the main board. For diagnostics, service centers use special test points or replace the module with a known-good one.
If the warranty period has expired and replacing the module is expensive, there is an alternative: using external Wi-Fi adapters (if the TV model supports specific models of dongles, which is rare for new models) or, more reliably, connecting via a TV set-top box.
Using an external set-top box (Android Box, Apple TV) relieves the load on the TV's processor and solves the Wi-Fi problem, as the set-top box has its own communication module. This is often a cheaper and more modern solution than repairing an old Smart TV.
Why does my LG TV see the network but not connect?
Most often, this is a DNS or date issue. The TV establishes a connection to the router (physical connection), but can't receive a response from the verification server (logical connection). Check DNS 8.8.8.8 and the date.
Is it possible to connect a TV via a phone?
Yes, you can share your phone's internet connection via Wi-Fi (hotspot mode). However, this quickly drains your data and battery. For continuous use, it's better to use a USB modem or connect your phone via USB cable (USB Tethering), if your TV supports it.
Does resetting the network help?
Yes, the network menu often has an option to "Delete Profile" or "Forget Network." This deletes the saved password and settings for a specific access point. You'll then need to re-enter the password. This can be helpful if your profile has accumulated configuration errors.
Does antivirus software affect the router?
Yes, some parental control features or built-in antivirus software in routers (for example, TrendMicro on Asus or antivirus software on Keenetic) can block unknown devices. Try temporarily disabling traffic filtering or whitelisting your TV's MAC address.
