The situation when modern Smart TV When a wireless network stops detecting itself, it often catches users by surprise. You turn on your favorite TV show, but the screen reports a lack of connection or simply doesn't display available access points. This is a common problem faced by TV owners. LG based on operating systems webOS And NetCast.
The reasons may lie either in a software failure of the router itself or in a hardware malfunction of the Wi-Fi module inside the TV. In 80% of cases, the problem is resolved by changing the static DNS address or completely resetting the network settings., which does not require calling a specialist.
Don't panic and immediately seek out a service center. Most often, the problem is a frequency conflict or a temporary file corruption in the operating system. In this article, we'll outline a step-by-step procedure that will help you restore your connection without unnecessary expense.
Basic diagnostics and initial reset
The first thing to do is to rule out basic equipment malfunctions. Often router It simply freezes and stops distributing IP addresses to new devices, although the Internet may work reliably on other gadgets.
Try performing a "cold" reboot. Turn off the TV with the remote, then unplug it. Wait at least 2-3 minutes. This time is necessary for the capacitors to fully discharge and the RAM to clear.
⚠️ Important: Do not use the "Quick Start" feature in the TV menu during diagnostics. It puts the device into sleep mode but does not completely turn it off, leaving errors in its memory.
Reboot your router at the same time. If after turning it on LG TV If your Wi-Fi connection isn't visible again, check if other devices (phone, laptop) can see your Wi-Fi hotspot. If the network connection is gone everywhere, the problem is definitely with the router.
If other gadgets are working but the TV is stubborn, proceed to a more in-depth setup. It's important to make sure the remote control isn't stuck or that the batteries are working properly, as the settings menu can sometimes be slow to respond.
Checking date and time settings
One of the most non-obvious reasons why LG TV can't connect to the internet, the date is out of date. Security protocols WPA2 And WPA3 require time synchronization to verify certificates.
If the device is set to the year 2015, but it's 2026, security servers will simply reject the connection request. Go to the settings menu and find the "Time and Date" section.
It's best to select the "Automatic Network Setup" (NTP) option. If the TV isn't yet connected to the internet, set the current date and time manually. After saving the settings, try scanning for networks again.
Users often ignore this point, considering it unimportant. However, clock desynchronization is what blocks the handshake protocol between the router and TV. After adjusting the time, the error may disappear immediately.
Manual DNS and IP address configuration
If automatic address acquisition doesn't work, you'll need to enter the settings manually. This is the most effective method when the TV detects the network but displays "No connection to server" or "Authorization error."
You'll need to access advanced Wi-Fi settings. Select your network from the list, but don't enter the password immediately. Look for the "Change" or "Advanced Settings" button (often marked with a gear or three dots).
- 📡 Switch the mode from “Auto” to “Manual”.
- 🔢 Enter the address in the DNS server field
8.8.8.8(Google) or1.1.1.1(Cloudflare). - 🔒 Leave the IP address field set to automatic or enter a static one if you know your subnet range.
Using public DNS servers often bypasses ISP blocking or corrects errors in the local DNS router. After entering the information, click "OK" or "Connect."
Changing the region and network name format
Some models Smart TV have regional restrictions. If the TV was purchased in another country or its settings are set to the wrong region, it may ignore certain communication channels.
Go to General Settings and check the country. For devices purchased in the CIS, this is usually Russia, Ukraine, Kazakhstan, or "LG Service Center." Changing the region may require a device reboot.
Also, pay attention to the name of your Wi-Fi network (SSID). Old modules in TVs LG may not display correctly or may not see networks that use the following in their names:
- 🔤 Cyrillic characters (Russian letters).
- 🎨 Special characters (e.g. #, %, &, spaces at the beginning or end).
- 📏 Network name is too long (more than 32 characters).
Try renaming the network in your router settings, using only Latin letters and numbers. Then, try searching again. This is especially true for models released before 2018.
Frequency range 2.4 GHz and 5 GHz
Modern routers operate in two bands. If your TV LG does not support the standard 802.11ac (5 GHz), it will not physically see the network if the router only operates in this mode.
Check your model's specifications. Budget and mid-range models often have modules that only operate at 2.4 GHz. Make sure this band is enabled on your router.
If your router broadcasts one network with a common name for both ranges (Smart Connect), try separating them in the router settings by giving them different names, for example, HomeWiFi And HomeWiFi_5GConnect your TV to the network without a 5G set-top box.
⚠️ Note: Router and TV interfaces are constantly being updated. The layout of menu items may vary depending on the webOS firmware version. Please refer to the instructions for your specific model for up-to-date screenshots.
Why can 5 GHz interfere?
The 5 GHz band has a narrower range. If the router is located far away or behind a thick wall, the 5 GHz signal will be weak, and the TV may constantly lose connection, even if it technically supports it.
Reset network settings and update software
When simple methods fail, a more radical approach is required: a complete reset of network settings. This will return the Wi-Fi module to its factory defaults, deleting all saved profiles and cache.
To do this, go to Settings → All settings → General → Network → Reset network settingsConfirm the action and wait for the module to reboot.
☑️ Checklist before reset
After the reset, try connecting again. If that doesn't help, check for system updates. Sometimes Wi-Fi module bugs are fixed with manufacturer patches.
You can try updating via a USB drive by downloading the firmware from the official website. LG to your computer. This will eliminate problems with downloading large amounts of data over unstable Wi-Fi.
Connection error code table
When attempting to connect, the TV may display various error codes. Understanding their meaning will help you find a solution faster.
| Error code | Description | Possible solution |
|---|---|---|
101 |
Incorrect password | Check your keyboard layout and letter case |
105 |
No response from the server | Change DNS to 8.8.8.8 |
107 |
Weak signal | Move your router closer or use a repeater |
112 |
IP conflict | Reboot your router to reset the DHCP table. |
If you see a code that's not in the table, write it down and look it up in the manufacturer's knowledge base. Often, the numerical designations are standardized across the entire product line.
Hardware problems and the Wi-Fi module
If software methods have been exhausted and the TV still doesn't see any networks (even neighboring ones), there's a high probability of a hardware failure. In TVs LG A separate module is responsible for wireless communication.
It can fail due to a power surge, lightning storm, or a manufacturing defect. Symptoms include a gray Wi-Fi icon that doesn't activate, or a complete lack of a network list even after a reset.
Some models combine the Wi-Fi module with Bluetooth. If your Magic Remote (which uses Bluetooth) also stops working, this confirms the diagnosis. The part needs to be replaced.
Replacing the module requires disassembling the TV and having soldering equipment or experience working with cables. It's best to entrust this procedure to service center specialists.
Why does the TV see the phone but not the router?
This indicates a compatibility issue with encryption standards. Your router may be configured to WPA3, and the old TV only supports WPA2Try lowering the security level in your router settings to WPA2-PSK (AES).
Is it possible to connect to the Internet via a USB modem?
LG TVs typically don't support direct 3G/4G internet connection via the USB port. The USB port is reserved for media files. Use your smartphone as a Wi-Fi modem.
Does factory reset delete apps?
Yes, full reset (General → Reset to Initial Settings) will delete all installed apps and logins. You'll have to sign in again to Netflix, YouTube, and other services.
