Why does my Samsung TV display error 102?

Your Samsung TV displays error 102 because of a connection issue. This could be between your TV and Samsung Smart Hub server. Your device can’t connect to the latter since it’s overloaded or on maintenance. But this can also be due to a bug or error. As well as poor Wi-Fi signal or router problems. 

Samsung TV error 102: 13 steps to fix it

#1: Cold boot your TV

If the error code 102 always appears on your screen, the first thing you can do is restart your Samsung TV.

This trick is the easiest compared to the other ones below. So if it works, you could save a lot of time.

Now, you might wonder, “What is a cold boot?” 

Rebooting (or restarting) means turning a device off and on.

It could be done in 2 different ways:

  • Warm (soft) – restarting a device without fully shutting its power off.
  • Cold (hard) – switching off an appliance while it’s still running and putting it in a powerless state. 

They almost do the same thing. However, a cold boot performs a more complete reset than warm.

And this might be what your TV needs.

How to cold boot your Samsung TV?

Option 1 (with a remote)
  1. While your TV is on, press the “Power” button on your remote.
  2. Hold it until it turns off and on again.
Option 2 (without a remote)
  1. Unplug your TV from the power outlet while it’s turned on.
  2. Wait for around 30 seconds.
  3. Once you finish counting, put the plug in again.

Then you’ll see your Samsung TV reboots on its own.

“How does this help?”

This isn’t visible. But the more we use our TVs, the more it accumulates electrical charge.

Now if it’s too much, it may result in errors or lags. And by rebooting your TV, you’ll be draining all of it.

#2: Power cycle your Wi-Fi connection

Okay. Don’t be confused here.

I only used a new term. But ‘power cycle’ also means restart or reboot.

However, this time, you’ll perform it on your router and modem instead.

So do this next if the first tip didn’t solve your connection problems.

“What’s the proper way to do it?”

  1. Remove the plug of your router and modem from the power socket.
  2. Wait for about 30 seconds. (This will allow your devices to cool down for a bit.)
  3. Plug in the cord of your modem. (It should turn on automatically. So if not, press its “Power” button.)
  4. After 60 seconds, plug in your router.
  5. Give the devices at least 2 minutes to complete their reboot. 
  6. Check your Samsung TV if the error code 102 still appears or not.

How does this help?

Routers and modems may look small. But inside them are operating systems similar to a computer.

And as I said before, these could run out of memory. Or have a build-up of residual charge over time.

So the best and easiest possible fix for this is simply restarting it.

This is also one of the tricks for Samsung TVs that always disconnect to Wi-Fi.

#3: Connect to a better network

If it seems like a Wi-Fi issue, check the network where your TV is connected first.

This is because modern routers are now ‘dual-band.’

“What does it mean?”

It means that routers can receive and send signals using 2 different frequencies.

2.4GHz vs 5GHz

First off, there are many devices that can connect to a 2.4GHz network. Say, baby monitors and garage door openers.

It can also penetrate solid walls and floors. So it provides huge coverage.

However, 2.4GHz is slower than 5GHz.

The latter is faster in transmitting data. But, it can only cover a small area.

This is because high frequencies like 5GHz can’t pass through rigid objects. Plus, not all devices have the ability to connect to it.

Which frequency is better for my Samsung TV?

For streaming and gaming, I’ll recommend 5GHz.

But, this will still depend on whichever works best on your device. So test both of them to be sure.


  1. Press the “Home” button on your Samsung TV remote.
  2. Go to Settings.
  3. Click “General.”
  4. Select “Network.”
  5. Find and choose “Open Network Settings.”
  6. Select the Wi-Fi network that you want to connect to. (5GHz may have ‘5’ in its name while 2.4GHz might have ‘2.4’ instead.)
  7. Once you’re done choosing, click it and enter your password.
  8. Select “Done” and press “OK.”

“Help! My Samsung TV can’t connect to the 5GHz network.”

Sadly, not all Samsung TVs can access the 5GHz network.

These are 2018 models and they only have 2.4GHz cards:

  • NU7200.
  • NU7100/NU710D.
  • NU7300/NU730D.

Now, if your Samsung TV uses the right network, it could also be that it’s overloaded.

Since there are too many devices, your TV may find it hard to connect and stay in the network. 

This is why an error code keeps on showing up.

How to fix it:

For this, you can try disconnecting all the other devices first. (Only those that are linked to that certain network.)

Doing this will help you trace the problem faster.

This is because if it doesn’t work, you can cross out the frequency or overloading issue. Then you could try the other tips below.

But if the problem is gone, you’ll know that you only need a stronger signal.

So, how can you achieve this?

#5: Relocate your router

Where is your router located?

If it’s hidden inside a cabinet or too far from your TV, it could be the reason for your poor signal.

We all know that Wi-Fi doesn’t spread equally inside a building.

Obviously, the devices closest to the router will have a better connection than those that aren’t. 

So if possible, move your router to the best possible location.

If you’re unsure where to place it, here are some things to consider:

  • Away from other devices: Place it far from other wireless devices to avoid signal interruptions.
  • Center: It’s best to place your router in the middle part of the house. This is so that signals can be transmitted radially to all of your rooms.
  • Open area: Keep your router away from any obstructions. As much as possible, relocate it in an open space – without covers and partitions.
  • High place: Put your router on a higher place to have a better connection. This is because Wi-Fi signals go down as they travel from the source. 

Note: To be sure, check your TV signal strength first. Go to “Settings,” select “General” and click “Network.” Now, select “Open Network Settings” and choose “Wireless.” Then take a look at the Wi-Fi bars shown on your screen to know if there are changes after the relocation.

#6: Reposition your router antenna/s

This simple trick might also work if you’re having a connection issue.

The job of the antennas in your router is to send and receive signals. So how they’re positioned will affect your connection.

These may be external or internal. And if your router has the former, try shifting their positions.

“Which way do I point my router antenna?”

  • For routers with 2 antennas: Point one up and the other to the side.
  • For routers with 1 antenna: Raise it upwards. This is to achieve better coverage laterally.

The reason for this is that antennas pointed upwards will spread signals to the sides.

While those pointed to the side will disperse data to the space above them.

So if you have 2 external antennas, it’s best to cover both areas for absolute connection.

But if the positioning isn’t the problem…

#7: Add or replace your router’s antenna

If your router doesn’t have visible antennas outside, it’s using internal ones.

So to boost your signal, consider getting a ‘high-gain’ antenna.

“What is it?”

As its name suggests, it ‘gains’ more in these aspects:

  • Coverage.
  • Wi-Fi speed.
  • Broadcast control.

So, adding it may help solve your signal problem.

Now, there are 2 types of it.

  • Directional – improves signals in a certain direction.
  • Omnidirectional – provides better coverage all over the area.

Directional antennas are long-range. So you can install and point it towards the weak spots.

But, it’s harder to set up.

While omnidirectional ones are handy. And you can easily put them anywhere. Since they have sphere coverage.

Note: Check compatibility first. See if the antenna supports similar frequencies as your router. (I’m talking about 2.4GHz and 5GHz.)

#8: Get a Wi-Fi range extender

Want an alternative to an extra antenna?

If so, you can also buy a device that can extend your Wi-Fi connection.

The less costly (but still effective) ones are called ‘range extenders.’

“What do they do?”

These receive signals from your router. And then they redistribute them to your wireless devices.

So think of them as little helping hands. As they aid your router in transmitting more data.

These come in different area coverage. So look for the best one that suits your needs.

Note: Range extenders expand your coverage. But these will not help if the problem is your home network.

#9: Consider a ‘Mesh Wi-Fi router’

“What are those?”

A range extender is a separate device that’s plugged into an outlet as support.

But a mesh Wi-Fi system replaces your router. And takes its job instead.

Yup. It’s said to be more effective in giving faster data. As well as covering dead zones.

“How is it different from the traditional one?”

A mesh Wi-Fi router combines 2 or more points. So it could give you a wide network of connections without worrying about the speed and quality.

Plus, it can cover up to 6,000 sq ft (557 sq m). This is why if you have a large area, this is a better choice.

But if not, it’s not a practical option. Since it’s more expensive than range extenders.

If you’re interested, here’s some of the best-selling mesh routers on Amazon:

We’re now in the modern world where almost everything is wireless.

So we may forget about this option – the wired Internet.

Yes. Take a look at the back of your Samsung TV. And you’ll see that there’s still a dedicated LAN port for ethernet.

You always see this on desktop computers, as well as on laptops.

And it can also be used in TVs to have a more stable Internet connection.

How to connect to a wired network:

  1. Get an ethernet cable.
  2. Connect the other end to your router.
  3. Plug the other one into your TV’s LAN port.
  4. On your TV, press the “Menu” screen.
  5. Go to “Settings.”
  6. Select “Network.”
  7. Click “Wired.”
  8. Wait until your TV finishes testing the connection. 
  9. Select “OK” once it’s done.


Since it’s wired, you’ll see a cord hanging at the rear of your TV. And you’ll also have limited options on where to place it due to the length of the wire.

So this could be a temporary solution only. Especially if you have to move your TV near to the router just to make this happen.

Note: If you still have connection problems, you might need to upgrade your home network. For this, contact your ISP or Internet Service Provider.

#11: Alter your TV’s DNS server

Okay. I just gave you a bunch of options to boost your Wi-Fi.

But what if you’re certain that your Internet is okay?

If this is the case, it could be that Samsung Smart Hub is the culprit.

Its server might be experiencing some problems. Like maintenance or overload.

And this is why you’re receiving an error code 102.

How to fix this:

Normally, this issue will resolve on its own. 

But if you want, here’s a method you can try to speed up the process. 

It’s by changing your DNS server:

  1. Press the “Menu” button on your remote.
  2. Click “Network.”
  3. Find and select “Network Settings.”
  4. Go to “DNS.”
  5. Input a public IP address. (For example, Google’s –

#12: Reset your Smart Hub

If the trip above doesn’t work, here’s another thing you can do.

  1. Press the “Home” button on your TV remote.
  2. Navigate to “Settings.”
  3. Select “Device Care” (or “Support” in other units).
  4. Click “Self Diagnosis.”
  5. Choose “Reset Smart Hub.”
  6. Enter your PIN. (If this is unchanged, the default is ‘0000’).
  7. Select “OK” once the reset is finished.

#13: Factory reset your TV

Factory Reset Your TV

Lastly, if the connection issue still persists…

You may need to perform a factory reset on your TV.

But, let me warn you.

This is different from a simple restart.

Reset will erase all the saved preferences on your Samsung TV. So you have to set them up all over again.

However, it could greatly help with your connection issues.  Especially if you’re sure that your Wi-Fi isn’t the problem.

How to do this:

  1. On your remote, press the “Home” button.
  2. Go to “Settings.”
  3. Click “General.”
  4. Select “Reset.”
  5. Enter your PIN (again, the default is ‘0000’).
  6. Hit “OK” once it’s done.
