LG TV WiFi Keeps Disconnecting? 8 Fixes That Actually Work

ByMyErrorFix

Quick Fix

Turn off Quick Start+ and restart your TV. Go to Settings > General > Quick Start+ and turn it off. Then unplug your TV for 60 seconds. This fixes the WiFi disconnecting issue for most LG TV owners.

There’s nothing more annoying than settling in to watch your favorite show, only to have your LG TV drop the WiFi connection. Again. And again. And probably again after that.

I’ve helped dozens of people fix this exact problem, and the good news is it’s usually a software issue – not a sign that your TV is dying. Let me walk you through what actually works.

Why Your LG TV Keeps Losing WiFi

LG TVs are notorious for WiFi issues, and there are a few common reasons:

  • Quick Start+ feature – This “convenience” feature actually causes most disconnection problems
  • Outdated firmware – LG releases updates that fix WiFi bugs
  • IP address conflicts – Your router assigned the same IP to multiple devices
  • 2.4GHz vs 5GHz confusion – Your TV might be jumping between networks
  • Distance from router – LG TVs have weaker WiFi receivers than you’d expect
  • DNS settings – Default DNS can cause connection drops

The thing is, this problem often starts randomly – your TV worked fine for months, then suddenly it can’t hold a connection. That’s usually a firmware or settings issue, which means it’s fixable.

How to Fix LG TV WiFi Disconnecting – 8 Solutions

1. Disable Quick Start+ (Most Common Fix)

Quick Start+ is supposed to make your TV turn on faster, but it’s buggy and causes all sorts of network problems. Turning it off fixes the WiFi issue for about 70% of people.

  1. Press the Settings button on your remote (gear icon)
  2. Go to All Settings (three dots at the bottom)
  3. Navigate to General
  4. Find Quick Start+ (might be under “Devices” on newer models)
  5. Toggle it OFF
  6. Unplug your TV from power for 60 seconds
  7. Plug it back in and test your WiFi

Why this works: Quick Start+ keeps network components in a half-awake state that causes connection instability. Fully shutting down the TV resets everything properly.

2. Power Cycle Your TV (The Right Way)

A proper restart clears the TV’s memory and network cache. But you need to do it correctly – just turning it off with the remote isn’t enough.

  1. Turn off your TV using the remote
  2. Unplug the TV from the wall outlet (not from the TV itself)
  3. Wait at least 60 seconds (seriously, count it out)
  4. While unplugged, press and hold the TV’s power button for 30 seconds (this drains residual power)
  5. Plug it back in
  6. Turn on the TV and reconnect to WiFi

This takes about 2 minutes but works surprisingly often.

3. Update Your TV’s Firmware

LG has released multiple firmware updates specifically addressing WiFi stability. If you’re running old firmware, updating might solve everything.

  1. Go to Settings > All Settings > General
  2. Select About This TV
  3. Click Check for Updates
  4. If an update is available, select Download and Install
  5. Don’t turn off your TV during the update (takes 5-10 minutes)

If your WiFi is too unstable to download the update, you can:

  • Connect via ethernet temporarily
  • Download the update to a USB drive from lg.com/support

4. Set a Static IP Address

When your router assigns a new IP address to your TV (which happens periodically), it can cause disconnections. Setting a static IP prevents this.

  1. First, find your current network info: Settings > Network > WiFi Connection > Advanced Settings
  2. Note down your current IP address, subnet mask, gateway, and DNS
  3. Go back to WiFi Connection
  4. Select your network and click Edit
  5. Toggle Set Automatically to OFF
  6. Enter your IP address (change the last number, e.g., if it’s 192.168.1.15, make it 192.168.1.200)
  7. Enter the same subnet mask, gateway, and DNS you noted earlier
  8. Click Connect

Using a high number like 200 for the last part of your IP helps avoid conflicts with other devices.

5. Change Your DNS Servers

Your ISP’s default DNS servers can be slow or unreliable. Switching to Google’s or Cloudflare’s DNS often improves connection stability.

  1. Go to Settings > Network > WiFi Connection
  2. Select your network and click Advanced Settings or Edit
  3. Find the DNS settings
  4. Change the DNS server to one of these:
    • Google DNS: 8.8.8.8 (primary) and 8.8.4.4 (secondary)
    • Cloudflare DNS: 1.1.1.1 (primary) and 1.0.0.1 (secondary)
  5. Save and reconnect

6. Switch to 5GHz WiFi (Or 2.4GHz)

If your router broadcasts both 2.4GHz and 5GHz networks with the same name, your TV might be jumping between them and losing connection each time.

Option A: Connect to a specific band

  1. Log into your router (usually 192.168.1.1 or 192.168.0.1)
  2. Find WiFi settings
  3. Give your 2.4GHz and 5GHz networks different names (e.g., “HomeWiFi” and “HomeWiFi_5G”)
  4. Connect your LG TV to just one of them (5GHz is faster but 2.4GHz has better range)

Option B: On the TV

  1. Go to Settings > Network > WiFi
  2. Look for an option to show 5GHz networks only (available on some models)
  3. Connect to your 5GHz network specifically

7. Turn Off Simplink (HDMI-CEC)

Simplink allows your TV to control other devices via HDMI, but it can interfere with network connections on some LG models.

  1. Go to Settings > All Settings > General
  2. Find Simplink (HDMI-CEC)
  3. Toggle it OFF
  4. Restart your TV

If you use Simplink to control a soundbar, you can try turning it back on after fixing WiFi to see if the problem returns.

8. Factory Reset Your TV (Last Resort)

If nothing else works, a factory reset will clear all settings and often fixes persistent WiFi issues. You’ll need to set everything up again, including logging into your streaming apps.

  1. Go to Settings > All Settings > General
  2. Scroll down to Reset to Initial Settings
  3. Enter the PIN (default is 0000 or 1234)
  4. Confirm the reset
  5. Wait for the TV to restart (takes about 5 minutes)
  6. Run through the initial setup and reconnect to WiFi

After the reset, make sure to disable Quick Start+ before testing your connection.

If Nothing Works

Still having problems? Here are some other things to try:

  • Use an ethernet connection – It’s more stable and faster than WiFi anyway
  • Get a WiFi extender – If your TV is far from the router, a good extender can help
  • Check your router – Older routers may not play well with smart TVs. Consider upgrading if yours is more than 5 years old
  • Contact LG support – There might be a known issue with your specific model. Call 1-800-243-0000 or visit lg.com/support

FAQ

Why does my LG TV disconnect from WiFi when turned off?

This is usually caused by Quick Start+ putting the TV in a low-power state that doesn’t maintain the network connection properly. Disabling Quick Start+ typically fixes this issue.

Why does my LG TV say “WiFi is turned off” randomly?

This is a known bug in some LG firmware versions. First, try updating your firmware. If that doesn’t help, do a factory reset and avoid restoring from a backup – set it up fresh.

Should I use 2.4GHz or 5GHz for my LG TV?

If your TV is close to the router (same room or one room away), use 5GHz for better speed. If it’s further away or there are walls between them, 2.4GHz will be more stable even though it’s slower.

Can a bad HDMI cable cause WiFi disconnection?

Surprisingly, yes – in rare cases. Poorly shielded HDMI cables can cause electrical interference. If you’ve tried everything else, try disconnecting all HDMI devices temporarily to test.

Wrapping Up

LG TVs are great when they work, but their WiFi issues are definitely frustrating. Start with disabling Quick Start+ and doing a proper power cycle – that combination fixes the problem for most people.

If you’re still stuck after trying these fixes, an ethernet adapter is a reliable backup plan that costs about $15 and gives you a rock-solid connection. Sometimes the simplest solution is the best one.
