9 Fixes: LG TV WiFi Keeps Disconnecting (2022 How-To)

LG TV WiFi Keeps Disconnecting

If there’s a movie that I’d use to describe my TV and its network, it’s Interstellar.

Why?

Because they’re so near each other, but the way they keep disconnecting…

The space between may as well be the distance between stars.

But, don’t worry.

You don’t need to be a rocket scientist to fix yours.

Keep reading to discover:

  • What type of ethernet cable you should buy.
  • An in-depth guide on how to safely replace your Wi-Fi module.
  • 9 easy ways to fix an LG TV that keeps disconnecting from the internet.
  • Which settings do you have to disable or tweak to connect to your network.
  • And so much more…

Why does my LG TV keep disconnecting from my WiFi?

Your LG TV keeps disconnecting from the Wi-Fi because of outdated firmware or a broken module. The TV could also be blocking 5GHz network signals. Otherwise, it’s because of your DNS, MAC, or DHCP settings. As well as other general settings like location, Quick Start, and SimpLink.


LG TV WiFi keeps disconnecting: 9 fixes


#1: Power cycle your devices

My first suggestion?

Turn your TV off and then on.

Seriously. Try it.

This process is called a power cycle.

Now, you might be confused about how restarting your TV can fix your issues.

I used to wonder that, as well.

And a technician friend of mine said this:

“Software doesn’t break. It comes broken.”

Essentially, stuck processes on your software can mess up your TV’s functions.

And yes, those processes include network connectivity.

Power Cycle Your Devices

What a power cycle does is that it forces a complete restart of your system. This method allows those stuck processes to get going again.

Got it? Great. Now, here’s what you need to do:

  1. Turn your TV off.
  2. Unplug it from the socket.
  3. Wait 30 seconds.
  4. Plug it back and turn it on.

Note: Do the same for your router or modem.

#2: Use an ethernet cable

Newer models of LG should have an ethernet port at the back of your TV.

So, instead of pulling your hair out trying to connect to a spotty Wi-Fi signal…

Why not connect your network directly?

Not only is ethernet more reliable, but they also provide faster and more secure internet.

Are you convinced? Now, let’s talk cables.

Here’s a list of ethernet cables, along with their speed and length, to help you decide:

CategorySpeedMax lengthMax Bandwidth
Cat 310MbpsNo information16MHz
Cat 510-100MbpsNo information100MHz
Cat 5e1000Mbps to 1GbpsNo information100MHz
Cat 610Gbps55 meters250MHz
Cat 6a10Gbps55 meters500MHz
Cat 7100Gbps15 meters600MHz
Cat 7a100Gbps15 meters1000MHz
Cat 840Gbps30 meters2000MHz

Note: Sometimes, it takes a while before your TV can recognize your ethernet. Sometimes, it can’t at all.

When that happens, you can trigger the connection manually with these steps:

  1. Press the Home button on your remote.
  2. Go to Settings.
  3. Under Network, select ‘Wired Connection (Ethernet).’

Doing so will force your LG to look for a wired network.

#3: Remove interference

This one’s a simple fix.

Take a look around your home, especially near your TV. 

Do you see any of the following:

  • Walls.
  • Radio.
  • Mirrors.
  • Microwave.
  • Baby monitors.
  • Bluetooth devices.

These items are known to interfere with your Wi-Fi signal. 

To prevent interference, move your router closer to the TV.

#3: Switch to 2.4GHz

Note: My router interface and yours might not be the same. If that’s the case, these settings should always be available under a ‘Wireless’ tab.

Step 1: Find your Wi-Fi’s IP address

First, you need to find your router’s IP address.

Usually, these are:

  • 192.168.0.1 
  • 192.168.1.1

On the rare times that this isn’t the case, you can find your IP address with these instructions:

  1. Grab a laptop.
  2. Open Command Prompt.
  3. Type and enter ‘ipconfig/all’.

Warning: Watch what you type. The command prompt is case-sensitive.

You should be able to find your IP address next to ‘Default Gateway.

Step 2: Access the web interface

After getting the IP address, use it to access your router’s web interface.

  1. Open a web browser.
  2. Type your IP address in the address bar.
  3. Enter the username and password that your ISP gave you.

And you’re good to go.

Note: Your router’s default username and password are ‘admin’ and ‘password.’

If you forgot your username or password, contact your ISP.

Step 3: Change the settings

It’s time to change your GHz settings.

  1. Expand Advanced Settings.
  2. Go to Wireless.
  3. Select Wireless Signal.
  4. Tick Disable Channel Optimization.
  5. Press Enable 2.4Gz, then Disable 5.0GHz.

Pro tip: Look for a setting called ‘MAC filtering.

That setting allows devices to connect to your Wi-Fi but block their network access.

Your router may be unknowingly blocking your TV’s internet access.

So, be sure to disable MAC filtering to prevent this from happening. 

Are you still confused about how to change GHz settings? It’s okay. It happens.

In that case, you can watch this video for a clearer presentation of how to do just that:

#4: Edit DNS settings

DNS allows your network to communicate with web servers.

But sometimes, these servers go down.

When DNS servers are offline, your TV’s own network connection can become spotty.

If that happens, what should you do?

Switch the DNS to something that doesn’t go down. At least, theoretically.

You see, your ISP usually provides your DNS. 

But, do you know that you can change that setting manually?

And, truthfully, it’s better that you do. Why?

Because Google developed DNS servers that are faster, more secure, and run on the Cloud.

Now, what are these servers, and how can you use them?

  1. Press the Home button on your remote.
  2. Under Settings, go to All Settings.
  3. Select Network.
  4. Choose Wi-Fi connection.
  5. Go to Advanced Wi-Fi Settings.
  6. Select the Edit button.
  7. Type ‘8.8.8.8’ or ‘8.8.4.4’ on the DNS bar.

#5: Change general settings

Do you know that your LG’s general settings can affect your connection too?

Yes, it can.

Which settings, you ask?

SimpLink

SimpLink is LG’s version of HDMI-CEC.

CEC allows all of your devices to be controlled with a single remote.

That means you don’t have to switch remotes to control your TV, gaming consoles, etc.

Sounds good, right? Sure, in theory.

But, the truth is that CEC implementation has been controversial. Why? 

For being buggy and unreliable.

Most notably, the signals from different infrared remotes interfere with the Wi-Fi network.

For LG TVs, this is how you can disable Simplink:

  1. On your remote, press the Home button.
  2. Under All Settings, go to General.
  3. Select ‘SIMPLINK (HDMI-CEC).’
  4. Untick the ON/OFF switch.

Location

Next, you also have to fix your location settings.

Sometimes, LG TVs input the wrong place as your region.

This mistake will then trigger your router to disconnect from the TV.

To remedy this, do these 7 easy steps:

  1. Open the launcher by pressing the Home button on your remote.
  2. Go to Settings.
  3. Under All Settings, select General.
  4. Select Location.
  5. Chose Service Area Zip Code.
  6. Enter your zip code.

Quick Start

Lastly, you’ll also need to disable Quick Start.

Quick Start puts your TV and its apps on standby mode whenever they’re closed.

It’s a handy setting, but it stops your apps from fully closing.

Soon, all of these open apps will cause your TV to glitch.

This is how you can turn Quick Start off:

  1. Press the Settings button on your remote.
  2. Under All Settings, go to General.
  3. Untick Quick Start.

#6: Update your LG’s firmware

Update Your LG's Firmware

Next, try to update your firmware.

You might be wondering:

“What’s firmware?”

Firmware is the software written for your hardware to do its job.

Fun fact: That’s actually the reason why it’s called firmware. It’s not soft, but not quite hard either. It’s firm.

Every once in a while, you’ll need to update your LG’s firmware. Why?

Outdated software can cause glitches in its hardware, including the Wi-Fi module. (More on that later.)

Now that we got that out of the way, it’s time to update.

Settings

First, let’s go ahead and try to update the firmware more traditionally:

Through the settings menu. Simply grab your remote and:

  1. Press the Home button.
  2. Under All Settings, go to General.
  3. Select About this TV.
  4. Then, press Check for Updates.
  5. Press Yes to confirm the update.

Flash drive

Now, let’s consider that you have trouble connecting to your Wi-Fi.

This handicap means that your TV can’t look for the newest firmware update by itself.

When that happens, don’t fret.

You can still update your LG with a flash drive.

Sure, it’s a long process, but it’ll be quick. I promise.

Start with:

Step 1: Download update

For this step, you’ll need a computer.

Once you’re face to face with a PC, proceed to:

  1. Go to LG’s downloads page.
  2. Type and select your TV’s model number.
  3. Download the latest firmware file.
Step 2: Move the update to a flash drive.
  1. Go to the downloaded file.
  2. Extract the update.
  3. Make a folder called ‘LG_DTV’ on your flash drive.
  4. Paste the extracted file to LG_DTV.
Step 3: Complete update
  1. Close your LG TV.
  2. Insert the flash drive at the back of your TV.
  3. Turn your TV on and then wait until a prompt appears.
  4. Press Yes to confirm the update.

#7: Replace Wi-Fi chip

As previously mentioned, there’s a hardware part inside your TV called the Wi-Fi module or chip

Now, what does it do?

That’s right. The name gives it away. 

The module allows your TV to connect to a wireless network.

Unfortunately, like all hardware, it doesn’t last forever. Here are the most common reasons why hardware breaks:

  • Age.
  • Factory defect.
  • Wear and tear.

In that case, there’s nothing you can do to fix it.

But you can always replace it.

Warning: Skip this step if you don’t have prior electronics repair experience. The wrong move may damage your TV or, worse, harm you.

Step 1: Access the module

Begin with buying a replacement module that is compatible with your LG TV.

Got yours? Next:

  1. Place your TV on a smooth surface.
  2. Remove the back of your TV with a screwdriver.
  3. Unscrew the remaining binds inside.
  4. Remove the tabs holding the plastic case on the bottom middle part of your TV.
  5. Flip the plastic case over. 

See that small green board? That’s the Wi-Fi module.

Step 2: Replace the chip

  1. Unclip the old module.
  2. Remove the ribbon cable that’s connecting it to the mainboard.
  3. Place the new Wi-Fi module in its place by clipping its binds.
  4. Connect the ribbon cable back in.

Note: Ensure that your cables are properly connected. A loose ribbon cable will disconnect the module from the mainboard.

#8: Use a gaming console

This one, admittedly, is a band-aid solution.

Something to keep your LG going until you find a real fix or replace your TV entirely.

First, ask yourselves this:

Why do you need internet for your smart LG TV?

I don’t know about you, but I use the internet on my TV to use streaming apps.

Guess what? Even without a direct connection, you can still do that on your TV.

That’s if you have a gaming console.

Simply connect your TV to your Xbox or PlayStation, and you’re good to go.

Now, the question is, which apps will be available to you through gaming consoles?

Xbox and PlayStation

Here’s a partial list of all the media apps that are available to PlayStation and Xbox devices:

#9: Contact LG

At the end of the day, we can’t do everything ourselves.

Sometimes, we need to ask for help from others. And there’s no shame in that.
