After helping dozens of friends and family members troubleshoot this exact problem, I’ve learned that most LG TV WiFi issues have surprisingly simple fixes. The frustrating part is knowing which solution to try first. That’s why I created this guide. You’ll get a step-by-step walkthrough that starts with the quickest fixes and progresses to more advanced solutions only when needed.

Whether your LG TV won’t find your WiFi network, keeps disconnecting, or shows that dreaded error code 106, this guide covers every solution I’ve personally tested and verified. By the end, you’ll have your LG TV connected and streaming again.

Quick Fixes That Work for Most LG TV WiFi Problems

Before diving into detailed troubleshooting, try these three quick fixes. They solve roughly 70% of LG TV WiFi connection issues without any complex menu navigation.

Fix 1: Power cycle both your TV and router. Unplug your LG TV from the wall outlet. Unplug your router and modem too. Wait a full 60 seconds. Plug the modem back in first, then the router, then your TV. This clears temporary network glitches that often cause connection failures.

Fix 2: Turn off Quick Start+. This LG feature is notorious for causing WiFi issues. Navigate to Settings > All Settings > General > Quick Start+ and toggle it off. Then unplug your TV for 30 seconds and plug it back in. This single fix has resolved connection problems for countless LG TV owners.

Fix 3: Forget and reconnect your network. Go to Settings > Network > WiFi Connection, select your network name, choose “Forget Network,” then reconnect and re-enter your password carefully. Sometimes the saved connection data gets corrupted.

LG TV Won’t Connect to WiFi: Step-by-Step Troubleshooting Guide

If the quick fixes didn’t solve your problem, work through these steps in order. Each one targets a specific cause of LG TV WiFi connection failures.

Step 1: Power Cycle Your TV and Router Properly

A proper power cycle clears the temporary memory that can hold onto corrupted network settings. Many users skip this step or do it incorrectly, then waste hours on more complex fixes.

First, unplug your LG TV from the electrical outlet. Do not just turn it off with the remote. The TV needs to be completely disconnected from power.

Next, unplug your router and modem from power as well. If you have a separate modem and router, unplug both.

Wait at least 60 seconds. This allows all capacitors to discharge and clears the temporary memory in all devices. While waiting, press and hold the power button on your LG TV for 30 seconds. This drains any residual power from the TV’s circuits.

Now plug your modem back in first. Wait for it to fully boot up and establish a connection with your ISP. This usually takes 2-3 minutes.

Then plug your router back in. Wait for the WiFi indicator lights to show a stable connection.

Finally, plug your LG TV back in and power it on. Try connecting to WiFi again through Settings > Network.

Step 2: Disable Quick Start+ Feature

Quick Start+ is an LG feature designed to make your TV turn on faster. However, it keeps network processes running in a low-power state that frequently causes WiFi connection failures. This is one of the most common yet least known causes of LG TV WiFi problems.

Navigate to Settings on your LG TV. Depending on your WebOS version, you may need to select “All Settings” or “Advanced Settings.”

Go to General > Quick Start+. Toggle the setting to OFF.

This is critical: after disabling Quick Start+, you must perform a full power cycle. Unplug your TV for 30 seconds, then plug it back in. Simply turning the TV off and on with the remote will not work because Quick Start+ keeps the TV in a standby state.

Once your TV restarts, try connecting to WiFi again. I’ve seen this fix work immediately for TVs that hadn’t connected in weeks.

Step 3: Forget and Reconnect to Your WiFi Network

Sometimes the saved network information on your LG TV becomes corrupted. Forgetting the network and reconnecting fresh often resolves this.

Go to Settings > Network > WiFi Connection. You should see a list of available networks.

Highlight your home network but don’t select Connect yet. Press the button that brings up additional options (usually the button with three dots or the “More” button on your remote).

Select “Forget Network” or “Delete Network.” This removes all saved data for that connection.

Wait 10 seconds, then select your network again from the list. Enter your WiFi password carefully. LG TVs are case-sensitive and will reject passwords with incorrect capitalization.

If your TV accepts the password but still won’t connect, try entering the password on a mobile phone first to confirm it’s correct. Then manually type it on the TV rather than using any saved password features.

Step 4: Verify Password Entry and Authentication Type

Password issues are more common than you’d think, especially with the LG on-screen keyboard. A single wrong character or incorrect capitalization will prevent connection.

First, verify your WiFi password on another device. Connect your phone or laptop to the same network using the exact password you plan to enter on the TV.

When entering the password on your LG TV, watch carefully for common errors. The LG keyboard sometimes auto-capitalizes the first letter. If your password starts with a lowercase letter, you need to manually switch to lowercase. Special characters like @, #, and $ can also be tricky on the TV interface.

Some users find it easier to use the LG ThinQ app on their smartphone as a remote. The phone keyboard is much easier for entering complex passwords accurately.

If you’ve recently changed your WiFi password or got a new router, your TV is likely trying to connect with the old credentials. Forgetting the network and reconnecting with updated information is essential.

Step 5: Change DNS Settings to 8.8.8.8

DNS settings translate website names into IP addresses. When your LG TV can’t reach the default DNS server from your ISP, it may appear connected to WiFi but fail to load any apps or content.

Go to Settings > All Settings > Network > WiFi Connection. Select your connected or attempting-to-connect network.

Look for “Advanced Settings” or “Edit” option. Select it.

Find the DNS setting. It’s usually set to “Auto” by default. Change it to “Manual.”

Enter 8.8.8.8 as the primary DNS server. This is Google’s public DNS server, which is highly reliable and rarely has connectivity issues.

For the secondary DNS, enter 8.8.4.4. This provides a backup if the primary is temporarily unreachable.

Save the settings and try connecting again. This fix is particularly effective for LG TVs that show as connected to WiFi but display “no internet” errors when trying to use apps.

Step 6: Toggle IPv6 Off

IPv6 is a newer internet protocol that some routers and LG TVs handle poorly. Disabling it forces your TV to use the older but more stable IPv4 protocol.

Navigate to Settings > All Settings > Network > WiFi Connection. Access the Advanced Settings for your network.

Look for an “IPv6” option. If it’s turned on, toggle it to OFF.

Save your changes and attempt to reconnect. This is a particularly helpful fix for users with older routers or mesh network systems like UniFi, Eero, or Google Nest WiFi.

Step 7: Check for and Install Firmware Updates

Outdated firmware can cause compatibility issues with modern routers and network security protocols. LG regularly releases updates that fix WiFi connectivity bugs.

If your TV has any connection at all (even intermittent), go to Settings > All Settings > General > About This TV > Check for Updates.

If your TV has no connection whatsoever, you’ll need to use the USB update method. Visit LG’s support website on a computer. Search for your specific TV model and download the latest firmware to a USB drive.

Insert the USB drive into your LG TV. The TV should detect the update file automatically. Follow the on-screen prompts to install the firmware.

After any firmware update, perform a full restart of your TV. Don’t just turn it off and on. Either unplug it for 30 seconds or use the restart option in the settings menu.

Step 8: Test Signal Strength and Router Proximity

LG TVs often struggle with weak WiFi signals, even when other devices work fine in the same location. The WiFi modules in some LG models are not as powerful as those in phones or laptops.

Check your WiFi signal strength in Settings > Network. If it shows less than 2 out of 3 bars, the signal is likely too weak for stable connectivity.

Move your router closer to the TV if possible. Even a few feet can make a significant difference, especially if walls or furniture block the signal.

Consider using a WiFi extender or mesh network node near your TV. This creates a stronger signal in that specific area.

If your router broadcasts both 2.4GHz and 5GHz networks, try connecting to the 2.4GHz network. It has better range and wall penetration than 5GHz, even though it’s slower. For streaming, 2.4GHz is usually sufficient.

Step 9: Perform a Factory Reset

If none of the above steps work, a factory reset restores your TV to its original state, clearing any corrupted settings that might be blocking WiFi connectivity.

Go to Settings > All Settings > General > System > Reset to Initial Settings. On some WebOS versions, this is under Support > Reset to Initial Settings.

The TV will ask for a confirmation code, usually displayed on screen. Enter this code to proceed.

Confirm that you want to reset the TV. The process takes 5-10 minutes. The TV will restart multiple times.

After the reset completes, you’ll need to go through the initial setup process again, including selecting your language, connecting to WiFi, and signing into your LG account.

Try connecting to WiFi during the initial setup. If it works during setup but fails later, note exactly what settings you change after the successful connection. This helps identify what triggers the problem.

WebOS Version-Specific Menu Paths

LG has changed the settings menu layout across different WebOS versions. Finding the right path for your specific TV can be frustrating when guides assume you have a different version.

To check your WebOS version, go to Settings > All Settings > General > About This TV. The WebOS version will be displayed there.

For WebOS 5.0 and 6.0 (2019-2021 models):

Network settings are located at Settings > Connection > Network > WiFi Connection. Quick Start+ is found under Settings > General > Quick Start+.

For WebOS 22, 23, 24, and 25 (2022-2026 models):

Network settings are at Settings > All Settings > Network > WiFi Connection. Quick Start+ is under Settings > All Settings > General > Quick Start+. The “All Settings” menu was introduced in WebOS 22 to reduce menu clutter.

If you can’t find a specific setting mentioned in this guide, use the search function in your TV’s settings menu. Press the microphone button on your remote and say the setting name, or look for a search icon in the settings interface.

Advanced Solutions for Persistent WiFi Problems

When standard troubleshooting doesn’t work, these advanced solutions address less common but serious connectivity issues.

Use Ethernet as a Reliable Alternative

If WiFi continues to fail, an Ethernet cable provides a stable, fast connection that bypasses wireless issues entirely. This is particularly useful for 4K streaming, which demands consistent bandwidth.

Connect an Ethernet cable from your router directly to the LAN port on your LG TV. Most LG TVs have a single Ethernet port on the back panel.

Go to Settings > Network. The TV should automatically detect the wired connection and connect to the internet. If it doesn’t, select “Wired Connection” manually.

If running a cable from your router to TV isn’t practical, consider powerline adapters. These use your home’s electrical wiring to transmit network signals between rooms. One adapter plugs into a wall outlet near your router, and another plugs in near your TV.

Router-Specific Configuration Issues

Some routers and ISP-provided gateways have settings that conflict with LG TVs. Users with T-Mobile 5G home internet, UniFi enterprise equipment, and some mesh networks report specific issues.

If your LG TV sees every WiFi network except yours, check your router’s security settings. Some LG TVs struggle with WPA3 security. Changing your router to WPA2 or WPA/WPA2 mixed mode often resolves this.

For UniFi users, ensure your access points aren’t using AI optimization features that change channels automatically. LG TVs sometimes lose connection when the channel changes. Set a static channel for your 2.4GHz network, ideally channel 1, 6, or 11.

Check if your router has MAC address filtering enabled. If so, you’ll need to add your LG TV’s MAC address to the allowed list. Find your TV’s MAC address in Settings > Network > WiFi Connection > Advanced Settings.

When to Contact LG Support

If you’ve tried every step in this guide and your LG TV still won’t connect to WiFi, the issue may be hardware-related. The WiFi module inside your TV could have failed.

Contact LG support if you experience these specific symptoms: The WiFi option is completely greyed out and cannot be selected, your TV doesn’t detect any WiFi networks at all while other devices see dozens, or you get error code 106 even after a factory reset and proper power cycle.

Before calling, have your TV model number and serial number ready. Also note the specific troubleshooting steps you’ve already attempted. This saves time and gets you to a solution faster.

If your TV is under warranty, LG may offer a free repair or replacement. Out-of-warranty repairs for WiFi modules typically cost between $100 and $200 depending on your TV model.

When to Contact Your Internet Service Provider

Sometimes the problem isn’t your TV at all. If multiple devices in your home are having connection issues, the problem likely lies with your internet service.

Contact your ISP if: every device in your home loses connection periodically, your router shows error lights, or you’ve recently changed internet plans or equipment. ISP technicians can check signal strength to your home and replace faulty modems.

If your LG TV is the only device having issues but you’ve exhausted all troubleshooting steps, ask your ISP if they’ve made recent changes to network security protocols or DNS settings that might affect smart TVs.

Understanding LG TV WiFi Error Code 106

Error code 106 is the most common WiFi-related error message on LG TVs. Understanding what it means helps you apply the right fix faster.

Error 106 means “Could not establish a connection to access point.” This indicates your TV can see your WiFi network but cannot complete the authentication and connection process.

The most common causes of error 106 are: incorrect password entry, Quick Start+ interference, IP address conflicts, or DNS resolution failures. Less commonly, it indicates a failing WiFi module.

To fix error 106, start with the Quick Start+ disable and power cycle combination. This resolves the majority of cases. If that doesn’t work, try the DNS change to 8.8.8.8 followed by forgetting and reconnecting to the network.

If error 106 persists after a factory reset, your TV likely has a hardware failure in the WiFi module. At this point, contacting LG support for repair options is your best course of action.

Some users report error 106 appearing only when using certain routers or after router firmware updates. If this matches your situation, check for router firmware updates or contact your router manufacturer for compatibility information.
