LG TV Keeps Disconnecting from WiFi: Causes & Solutions
If your LG Smart TV keeps disconnecting from WiFi, you’re not alone. This is a common issue that can be caused by network problems, TV settings, outdated software, or even interference from other devices. The good news is that most WiFi connection problems can be fixed in a few simple steps.
This guide covers the most common causes and step‑by‑step solutions to help you get your LG TV back online and keep it connected.
Common Causes of LG TV WiFi Disconnecting
Before jumping into fixes, it helps to understand what might be going wrong.
1. Weak or Unstable WiFi Signal
If your TV is far from the router or blocked by walls, furniture, or appliances, the signal may drop frequently.
2. Router Issues
Outdated firmware, overheating, or incorrect router settings can cause random disconnections.
3. LG webOS Software Bugs
An outdated or buggy version of LG’s webOS can interfere with WiFi stability.
4. Network Congestion
Too many devices using the same network can overload your router, especially on 2.4GHz networks.
5. Incorrect Network Settings
Wrong DNS settings, IP conflicts, or corrupted network data can cause recurring disconnects.
6. Power Saving Features
Some LG TVs turn off WiFi to save power, especially when idle.
Solutions to Fix LG TV WiFi Disconnection Issues
Follow these solutions in order. Many users find the problem fixed after the first few steps.
1. Restart Your TV and Router
This clears temporary glitches.
Steps:
- Turn off your LG TV and unplug it.
- Unplug your router and modem.
- Wait 60 seconds.
- Plug in the router and modem first.
- Once the internet is stable, plug in and turn on the TV.
2. Move the TV Closer to the Router
If possible, reduce the distance between your TV and router or remove obstacles like walls and cabinets.
Tip: If the signal improves when the TV is closer, the issue is signal strength.
3. Switch to a 5GHz Network
LG TVs often perform better on 5GHz WiFi.
How to check:
- Go to Settings → Network → WiFi Connection
- Select your 5GHz network (if available)
Note: 5GHz is faster but has a shorter range than 2.4GHz.
4. Update LG TV Software
Software updates often fix known WiFi bugs.
Steps:
- Go to Settings → All Settings
- Select Support → Software Update
- Enable Allow Automatic Updates
- Install any available updates
5. Disable Quick Start+ (Common Fix)
Quick Start+ can cause WiFi connection issues on some LG TVs.
Steps:
- Go to Settings → All Settings
- Select General
- Turn Quick Start+ OFF
- Restart the TV
6. Change DNS Settings Manually
Using a public DNS can improve connection stability.
Steps:
- Go to Settings → Network → WiFi Connection
- Select Advanced WiFi Settings
- Turn off Set Automatically
- Enter a DNS manually:
- 8.8.8.8 (Google DNS)
- Save and reconnect
7. Reduce Network Congestion
Disconnect unused devices from your network or upgrade to a router that supports more devices.
Tip: Streaming, gaming, and video calls on multiple devices can overwhelm older routers.
8. Reset Network Settings on LG TV
This clears corrupted WiFi configurations.
Steps:
- Go to Settings → All Settings
- Select General → Network
- Choose Reset Network
- Reconnect to your WiFi
9. Try a Wired Ethernet Connection
If WiFi keeps failing, a wired connection is the most stable option.
What you need:
- Ethernet cable
- Router near the TV
Plug the cable into your TV and router, then go to Network Settings to connect.
10. Factory Reset (Last Resort)
Only do this if nothing else works.
Steps:
- Go to Settings → All Settings
- Select General → Reset to Initial Settings
- Follow on‑screen instructions
⚠️ This will erase all apps and settings.
When to Contact LG Support
If your LG TV:
- Disconnects from all networks
- Won’t detect any WiFi networks
- Has persistent issues after a factory reset
Then the WiFi module may be faulty. Contact LG Support or an authorized service center for further assistance.

Frequently Asked Questions
Wi-Fi problems on LG TVs often come from software glitches, router conflicts, or power-saving features. Adjusting TV settings, checking the router, and keeping firmware updated can fix most issues.
What steps can I take to troubleshoot my LG TV’s Wi-Fi connection issues?
Start by power cycling the TV. Unplug it, hold the power button on the TV for about a minute, then plug it back in. Restart the router as well.
Check if features like Quick Start+ or Simplink (HDMI-CEC) are enabled. Turn them off, as they can interfere with Wi-Fi. Also, test the signal strength near the TV to rule out weak coverage.
How do I reset the network settings on my LG TV to improve Wi-Fi connectivity?
Go to Settings > All Settings > Network > Wi-Fi Connection. Choose the current network and select Forget Network.
Reconnect by entering the Wi-Fi password again. This clears any saved connection errors and forces the TV to establish a fresh link with the router.
Why does my LG TV lose its Wi-Fi connection after turning off or going into standby mode?
This often happens because of the Quick Start+ feature. When enabled, the TV doesn’t fully shut down and may fail to reconnect properly.
Turning off Quick Start+ in the General Settings usually stops this issue.
Can a firmware update resolve the Wi-Fi disconnection problem on my LG TV?
Yes. Outdated firmware can cause bugs that affect Wi-Fi stability.
Check for updates under Settings > All Settings > General > About This TV > Check for Updates. Install the latest version and restart the TV.
What should I check in my router settings to ensure it’s compatible with my LG TV?
Confirm the router broadcasts on 2.4GHz or 5GHz bands. Some LG TVs have trouble with hidden SSIDs or unusual security settings.
Make sure WPA2 security is enabled and DHCP is active so the TV can get an IP address automatically.
How can I change the DNS settings on my LG TV to maintain a stable Wi-Fi connection?
Open Settings > All Settings > Network > Wi-Fi Connection > Advanced Settings. Disable Set Automatically under DNS.
Enter a manual DNS server such as 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare). Save the settings and reconnect to test stability.
