If you are looking for a TV with sleek designs, advanced features, and user-friendly interfaces, LG TV is a popular choice.
However, even the most reliable technology can encounter issues, and one of the most common frustrations among LG TV owners is frequent WiFi disconnection.
This issue could pop its ugly head when you are streaming your favorite show, downloading updates, etc. Generally an unstable internet connection can disrupt your viewing experience, but here’s how you can fix it.
Check Basic Network Settings
Before diving into more advanced solutions, make sure you verify your basic network settings. This is because a simple connectivity issue could be what’s causing your LG TV to disconnect from WiFi.
1. Confirm that your router is functioning properly. Check if other devices in your home can connect to the WiFi network without issues.
2. Verify that your LG TV is attempting to connect to the correct network. Sometimes, TVs may try to connect to neighboring networks or previously saved connections.
3. Check for any potential signal interference. Keep your TV away from other electronic devices that might disrupt the WiFi signal, such as microwaves or cordless phones.
4. If possible, try moving your router closer to the TV to improve signal strength.
Restart Your Devices
A simple restart can often resolve connectivity issues by clearing temporary glitches and refreshing network connections.
Power Cycle Your LG TV:
1. Unplug your TV from the power outlet.
2. Press and hold the power button on the TV (not the remote) for about 30 seconds. This helps discharge any residual power in the device4.
3. Wait for an additional 60 seconds.
4. Plug the TV back in and turn it on.
Reboot Your Router:
2. Unplug your router from the power source.
2. Wait for at least 30 seconds. This allows the router to fully shut down and clear its memory.
3. Plug the router back in and wait for it to fully restart. This usually takes a few minutes.
After both devices have restarted, attempt to reconnect your LG TV to the WiFi network. In many cases, this simple process can resolve intermittent connectivity issues and restore a stable connection
Modify DNS Settings
Changing the DNS settings on your LG TV can help improve internet speed, reduce buffering, and resolve connectivity issues. Here’s how you can manually set a DNS server:
1. Press the Settings button on your remote and navigate to the Network section.
2. Select WiFi Connection and ensure you’re connected to your home network.
3.Scroll down and select Other Network Settings or Advanced WiFi Settings.
4. Click Edit and uncheck the option for Set Automatically.
5. Navigate to the DNS Server field and clear the existing entry.
6. Type in a popular DNS server like Google’s (8.8.8.8) or Cloudflare (1.1.1.1).
7. Press Enter to save the changes.
8. Click Connect to apply the new settings and test your internet connection.
Adjust Location Settings
Sometimes, adjusting your LG TV’s location settings can resolve connectivity issues caused by regional restrictions or mismatched configurations.
1. Press the Settings button on your remote and navigate to the General > System Settings section.
2. Select Location 
3. Select Broadcast Country
4. Temporarily change it to another country (e.g., Canada or UK).
5. After changing the location, you may be required to input a password. The default password is 0000
6. Restart your TV to refresh its settings.
5. Go back to the location settings and switch it back to your actual country.
Update Software/Firmware
Keeping your LG TV’s software up to date is important for ensuring the best performance, fixing bugs, and maintaining compatibility with new apps and features. Here’s how to update your LG TV firmware:
1. Press the Settings button on your remote and navigate to All Settings > Support > Software Update.
2. Select Check for Updates. If an update is available, click Download and Install.
3. Once the update is downloaded, power off the TV for 10 seconds, then turn it back on to complete the installation.
4. Enable Auto Update to ensure future updates are installed automatically.
Disable Quickstart or Auto Optimization
Quickstart and auto-network optimization features can sometimes interfere with WiFi connectivity by prioritizing speed over stability. Disabling these settings may help resolve frequent disconnections.
Disable Quickstart
1. Press the Settings button on your remote and go to All Settings > General > Quickstart+.
2. Toggle Quickstart+ off to prevent it from interfering with your network connection during startup.
Disable Auto-Network Optimization
1. Log into your router’s settings interface (usually accessible via a web browser at 192.168.x.x).
2. Navigate to network optimization settings (the exact location varies by router model).
3. Disable any auto-optimization features that might be altering WiFi signal priorities.
Advanced Fixes
If basic troubleshooting steps haven’t resolved the issue, these advanced fixes can address deeper problems related to hardware or software. These solutions require extra care but can often resolve persistent WiFi disconnection issues on LG TVs.
1. Clean the WiFi Module
Over time, dust or physical damage to the WiFi module inside your LG TV can cause connectivity problems. Cleaning or reseating the module may help restore a stable connection.
1. Power off your TV and unplug it from the power source.
2. Carefully remove the back panel of your TV using a screwdriver (refer to your TV’s manual for guidance).
3. Locate the WiFi module, which is typically near the bottom or side of the TV.
4. Use a soft brush or compressed air to gently clean any dust or debris around the module and its ribbon cable.
5. Ensure the ribbon cable is securely connected.
6. Reassemble the TV, plug it back in, and test the WiFi connection.
If cleaning doesn’t resolve the issue, you may need professional assistance to replace a faulty WiFi module.
2. Perform an HDMI Reset
Sometimes, HDMI-connected devices can interfere with your TV’s network settings due to signal conflicts. An HDMI reset can help eliminate this issue.
Steps for an HDMI Reset:
1. Disconnect all HDMI cables from your LG TV.
2. Power off the TV and unplug it from the wall outlet.
3. Wait for at least five minutes to allow residual power to discharge.
4. Plug the TV back in, turn it on, and reconnect the HDMI cables one by one while testing the WiFi connection.
3. Factory Reset Your TV
A factory reset can resolve software-related issues by restoring your LG TV to its original settings. Note that this will erase all saved data, including apps and settings.
Steps for a Factory Reset:
1. Press Settings on your remote and navigate to All Settings > General > Reset to Initial Settings.
2. Confirm the reset and wait for the process to complete.
3. Once the TV restarts, set it up again and reconnect it to your WiFi network.
A factory reset is often effective in resolving persistent software glitches causing connectivity problems.
4. Use an Ethernet Cable as an Alternative
If wireless connectivity remains unstable despite troubleshooting, consider using a wired Ethernet connection for a more reliable internet experience.
Steps for Ethernet Setup:
1. Connect one end of an Ethernet cable to your router and the other end to your LG TV’s Ethernet port.
2. Go to Settings > Network > Wired Connection (Ethernet) on your TV.
3. Follow on-screen prompts to establish a wired connection.
While this doesn’t fix WiFi-related issues directly, it provides a stable alternative for uninterrupted streaming and updates.
