Owning a modern smart TV means constant access to online content, whether it's streaming services, a browser, or system updates. However, users often encounter a situation where, instead of the familiar interface, an internet connection error message appears. On LG devices with the webOS operating system, one of the most common error codes is error 106. This code indicates that the TV's software is unable to connect to the update server or network, even if the router is functioning properly.
The problem can be caused by a variety of factors, from a simple router malfunction to incorrect DNS settings within the TV itself. Users often panic, believing the WiFi module has burned out or a critical hardware failure has occurred. In most cases, the situation can be resolved using software solutions without the need to contact a service center. It's important to understand that error 106 - This is usually a network configuration conflict, not a physical failure.
In this article, we'll detail the diagnostic and troubleshooting algorithms for this error. We'll cover everything from simple steps like rebooting to more complex DNS settings and resetting network parameters. Understanding the nature of this error code will help you quickly restore your TV to full functionality.
Causes of connection errors on webOS
Before you begin any active repairs, you need to understand why the system is displaying this particular code. Error 106 On LG TVs, this error most often indicates an inability to connect to the manufacturer's servers to check for updates or log in to LG Service. This may occur due to temporary unavailability of the company's servers, which occurs during maintenance.
However, if the problem persists, the cause lies with the local network. The router may be blocking the TV's requests due to security settings or an overflowing DHCP table. Another common culprit is incorrectly set time and date on the TV, which invalidates SSL security certificates and causes the connection to be lost.
⚠️ Attention: If error 106 appears after a power surge or sudden power outage, there's a high probability that your network settings have been reset to factory defaults, which may no longer be relevant for your current provider.
Another factor is the outdated version of the operating system. webOSOld encryption protocols may not be supported by new routers or the update server itself. In such cases, manual intervention in the settings or a forced firmware update via USB drive is required.
Basic reboot of equipment and network
The simplest and most often overlooked solution is a complete reboot of all network devices. Many users simply turn off the TV with the remote, putting it into standby mode, but this doesn't completely reset the network modules. A so-called "cold" reboot is necessary.
First, unplug the TV from the power outlet. Wait at least 2-3 minutes. This time is necessary for the capacitors to discharge and the device's RAM to clear. It is also recommended to reboot your router, as it is often the source of problems with IP address assignment.
After turning on the router, wait for its operating system to fully load (usually 1-2 minutes), and only then turn on the TV. Check if the problem has disappeared. error 106If the problem persists, proceed to deeper configuration.
☑️ Proper network reboot
Setting up automatic and manual network parameters
If a simple reboot doesn't help, you should check the connection settings in the TV menu. It often happens that automatic settings (DHCP) don't work correctly, and the device is assigned the wrong gateway or DNS. Go to the settings menu and select All Settings → Network → WiFi Connection.
Try deleting the current network and adding it again. To do this, click on your network name and select "Forget Network" or "Delete." Then reconnect, entering the password. This refreshes the handshake between the router and TV.
In some cases, manual DNS server configuration is required. Proprietary DNS providers may block or process requests to LG servers slowly. Try specifying public DNS from Google or Cloudflare. To do this, in the advanced WiFi settings, select "Edit" and enter the DNS server in the field. 8.8.8.8.
⚠️ Attention: When manually setting the IP address, make sure you do not specify an address that is already taken by another device on your local network, otherwise an IP conflict will occur.
Also check the date and time. An incorrect date is a common cause of error 106, as it disrupts certificate security checks. Make sure that the menu General → Time and Date Automatic synchronization via the network is enabled or the current values are set manually.
Reset network settings to factory defaults
When standard methods fail, a complete reset of the TV's network settings is an effective solution. This will restore all connection settings to their original state, deleting saved passwords and configurations. This does not affect your personal data, app accounts, or display settings.
To perform a reset, go to the menu Settings → All settings → General → Reset network settings (The path may vary slightly depending on your webOS version.) The system will ask you to confirm the action. Once approved, the TV will reboot.
After turning it on, you'll need to re-find your WiFi network and enter the password. This method eliminates errors that may have accumulated in the network configuration files over the life of the device.
| Parameter | Before the reset | After reset |
|---|---|---|
| Saved WiFi networks | All previously connected | Removed |
| DNS/DHCP settings | User or provider | Automatic |
| WiFi passwords | Saved | Removed |
| Personal data of applications | Saved | Saved |
Updating firmware via USB drive
If your TV can't connect to the internet due to error 106, it's unable to update over-the-air (OTA). However, an old software version may be blocking the connection. In this case, the only option is to manually update via a USB flash drive.
You'll need a computer with internet access and a USB drive with at least 1 GB of storage, formatted as FAT32. Go to the official LG support website, find your TV model, and download the latest firmware version.
Unzip the archive and copy the firmware file (usually with an .epk or .zip extension, but do not unzip the archive itself unless instructed otherwise) to the root directory of the flash drive. Insert the drive into the TV's USB port.
Your TV should automatically detect the update and prompt you to install it. If this doesn't happen, go to Settings → Support → Software Update → Update from USB. Follow the instructions on the screen. During the process strictly prohibited turn off the TV or remove the flash drive.
What should I do if my TV doesn't see the update file on my flash drive?
Make sure the flash drive is formatted in FAT32 (NTFS may not work). The firmware file should be located in the root directory, not in any folders. Also, try using a smaller flash drive (up to 8-16 GB), as some older TV models do not support larger memory capacities.
Router diagnostics and third-party factors
Sometimes the problem isn't with the TV, but with the router settings. Check if MAC address filtering is enabled. If your router is configured to only work with a specific list of devices, the new TV (or TV after a reset) will be blocked. Add the TV's MAC address to the allowed list in the router settings.
It's also worth paying attention to the frequency range. Some older LG models may not work correctly with 5 GHz networks or mixed b/g/n/ac mode. Try temporarily separating the 2.4 GHz and 5 GHz networks in your router settings by giving them different names, and then connect your TV to the 2.4 GHz network.
⚠️ Attention: Your computer's antivirus software or your router's parental control settings may be blocking your TV's access to certain ports required for LG services. Try temporarily disabling filtering.
If all else fails, there may be a signal issue. A weak signal leads to connection timeouts, which the system interprets as error 106. Use a WiFi analyzer on your smartphone to check the signal strength where the TV is installed. If necessary, use a WiFi extender.
Why does error 106 only appear at certain times of day?
This may indicate WiFi congestion from neighbors or scheduled maintenance on the provider's/LG's servers. It's also possible that the provider is throttling speeds or limiting traffic during peak hours.
Could error 106 indicate a faulty WiFi module?
Yes, if resetting the settings, updating the firmware, or connecting to a different network (for example, using a phone via a hotspot) doesn't help, the physical WiFi module inside the TV is likely faulty. In this case, a repair service or a LAN cable will be required.
Does changing your WiFi password affect error 106?
Absolutely. If you've changed the password on your router, the TV will try to connect with the old password and receive access denial, which the system may interpret as a network error. You'll need to delete the network on the TV and enter the new password.
