One of the most common issues with Smart TVs is when an LG smart TV suddenly loses connection to the home network or refuses to connect to the router. This typically occurs after a scheduled firmware update, a change in router security settings, or a power surge that could disrupt the network module's settings. Users encounter an endless connection loop or a "No Network" error, making it impossible to use streaming services and online movie theaters.
In most cases, the problem isn't a hardware failure of the Wi-Fi adapter, but a software conflict with addresses or incorrect DNS queries. The webOS operating system installed on modern models LG Smart TV, is sensitive to changes in encryption protocols and frequency ranges. Before taking your equipment to a service center, it's worth conducting a comprehensive diagnostic, as 90% of problems can be resolved using software.
The exact steps will depend on your specific device model and operating system version. We'll cover both basic steps for rebooting your device and advanced methods for setting up static IP addresses that can help in complex situations. It's important to follow the instructions carefully to eliminate human error.
Primary diagnostics and basic reboot of equipment
The first step should always be a full reboot of the entire ecosystem, not simply putting the TV into standby mode. Many users mistakenly believe that turning off the TV with the remote will de-energize it, but Smart TV It often remains in deep sleep mode, storing errors in RAM. To properly reset it, unplug the power cord for at least one minute.
At the same time, you should also reboot your router. Routers that operate 24/7 can overflow their DNS cache or experience IP address conflicts, assigning already-used addresses to new devices. Unplugging the router for 30-60 seconds allows it to completely clear its cache and initiate a new connection with the ISP.
☑️ Initial Reset Checklist
After turning on the equipment, pay attention to the indicators. If your LG TV still won't connect to Wi-Fi, check whether other devices can see your network. This will help pinpoint the problem: if your smartphone isn't working either, the issue lies with your ISP or router, not the TV. If other devices are working, the problem lies with the TV's network module.
⚠️ Caution: Don't try to re-enter the password frequently without rebooting. After 3-5 unsuccessful attempts, the router's security system may temporarily block the TV's MAC address, making it impossible to connect even with the correct password.
Checking date, time, and regional settings
One of the most non-obvious reasons why LG Smart TV can't connect to servers or Wi-Fi, and the date and time are out of order. Security protocols SSL/TLSThe security certificates used to encrypt traffic require that the time on the client device and the server match precisely. If the clocks are slow or show the wrong year, the security certificates are considered invalid, and the connection is blocked.
To check and adjust, go to the settings menu. The path usually looks like this: Settings → All settings → General → Time and dateMake sure the "Automatically over network" box is checked. If automatic syncing doesn't work due to lack of internet access, manually set the current values, down to the minute.
It's also worth checking your region. Some LG TV models may experience conflicting Wi-Fi frequency bands when changing regions (for example, when moving or buying equipment imported from another country). Make sure this is set in the settings. General → Location Your country is selected. An incorrect region may restrict the operation of certain channels or communication protocols.
Setting up DNS and a static IP address
Often, the problem lies in the TV's inability to obtain a valid address from the router's DHCP server or its use of the ISP's slow DNS servers. In this case, the best solution is to manually configure the network connection. You'll need to go to Settings → Network → Wi-Fi connection → Advanced Wi-Fi Settings (Additional settings).
In the menu that opens, disable the "Edit automatically" or "Auto-configure" option. After this, fill in the fields manually. The IP address should differ from the router's address only in the last digit (for example, if the router is 192.168.1.1, then the TV can be assigned 192.168.1.55). The gateway and subnet mask are usually copied from the automatically obtained values, but it's better to specify public and fast DNS servers.
We recommend using the following DNS addresses, which work reliably with Smart TV:
- 🌐 Google DNS:
8.8.8.8And8.8.4.4 - 🌐 Cloudflare:
1.1.1.1And1.0.0.1 - 🌐 OpenDNS:
208.67.222.222
After entering the data, save the settings and test the connection. If your LG TV has connected to Wi-Fi but the internet isn't working, try changing the DNS to an alternative one from the list. Sometimes providers block default DNS, and replacing it with Cloudflare Solves the problem of access to content.
| Parameter | Meaning (Example) | Description |
|---|---|---|
| IP address | 192.168.1.X | Unique TV address on the network |
| Subnet mask | 255.255.255.0 | Determines the size of the network |
| Gateway | 192.168.1.1 | Your router's address |
| DNS server | 8.8.8.8 | Name server address |
What should I do if the IP address fields are inactive?
On some LG models, the settings are hidden when you select "Simple" mode. You must switch to "Advanced Settings" mode or select "Manual" connection type to enable the input fields.
Impact of the 2.4 GHz and 5 GHz frequency bands
Modern routers often operate in two ranges: 2.4 GHz and 5 GHz. Older or budget LG TV models may simply not see 5 GHz networks, as their Wi-Fi modules only support the 802.11n (2.4 GHz) standard. If your router broadcasts a single network with a common name (Smart Connect), the TV may attempt to connect to an unsupported frequency.
It is recommended to separate networks in the router settings by giving them different names, for example, HomeWiFi And HomeWiFi_5GTry connecting your TV to a 2.4 GHz network, as it has better wall penetration and is more compatible with household appliances. The 5 GHz band is good for speed, but has a shorter range.
It's also worth paying attention to Wi-Fi channels. In the 2.4 GHz band, channels 1, 6, and 11 are considered the most stable. If the router automatically selects a channel that's congested due to neighboring devices, the TV may lose connection. Fix the channel in the router settings to one of the three specified.
⚠️ Note: Router interfaces and available channel settings may vary depending on the device model and firmware version. If you are unsure, please consult your router manual or your ISP to avoid disrupting your home network.
Reset network settings and update firmware
If software glitches have accumulated, you may need to perform a full reset of your TV's network settings. This will delete all saved Wi-Fi networks and passwords, returning the network module to its factory default settings. To do this, go to Settings → All settings → General → Reset all settings (or specifically "Reset network settings" if that option is available on your version of webOS).
After the reset, the TV will reboot. Try searching for the network again and entering the password. If the problem persists, there may be a critical error in the TV firmware that the manufacturer has already fixed. Updating the firmware is an important diagnostic step.
Since you can't update via Wi-Fi, use alternative methods:
- 📡 Mobile TV Link: Use the official LG ThinQ app on your smartphone to transfer the firmware file to your TV.
- 💾 USB drive: Download the latest software from the official LG website to your computer, transfer it to a flash drive, and run the update via the USB port on your TV.
When updating via USB, make sure the flash drive is formatted to FAT32. The firmware file should be located in the root directory of the drive, not in any folders. The update process may take up to 15 minutes, during which time the TV may turn off and on automatically.
Hardware problems and the use of external adapters
If none of the software solutions have helped, and your LG TV has stopped connecting to Wi-Fi even after a factory reset, there's a high probability of a hardware issue. This could include a faulty internal Wi-Fi module, oxidized antenna contacts, or a problem with the motherboard.
An external USB Wi-Fi adapter can be used as a temporary or permanent solution. However, not all adapters are compatible with LG TVs. Only original LG modules (e.g., AN-WF500, AN-WF100) are officially supported. Third-party adapters from TP-Link or D-Link will likely not be detected by the system.
Also, a great solution is to use technology Screen Share Or Chromecast built-in. You can stream content from your smartphone or tablet to your TV using the smartphone as a bridge. In this case, the smartphone receives the Wi-Fi signal, while the TV receives the video stream, thereby bypassing the issue of a weak module.
Why does the TV see the network, but says “Not connected”?
This is a classic sign of an incorrect password or incompatible encryption type. The router may be using the WPA3 standard, which older LG models don't support. Try changing the router's security type to WPA2-PSK (AES).
Can an antivirus on a computer block a TV?
Yes, if a PC connected to the same network has a strict firewall or antivirus with the "Home Network Protection" feature, it may perceive the new device (TV) as a threat and block its access to the Internet.
Will resetting my network settings reset my apps?
No, reset network settings (Network Reset) only affects internet connection settings. All installed apps, accounts, and display settings will remain intact. A full reset (factory reset) is not required.
