Samsung TV won’t stay connected to WiFi: 11 fixes

#1: Soft reset the TV

It’s normal for smart devices to have glitches from time to time, especially smart TVs like Samsung’s.

Smart TVs store and run multiple apps and data on their system. Sometimes causing it to freeze or run into some software errors.

As a result, the device can fail to establish a stable connection with your WiFi. Causing it to disconnect while in use.

If this happens to your Samsung TV, the first and easiest solution you can do is to soft reset your device.

Soft resetting is rebooting your TV by completely shutting down its power and system.

There are 2 ways you can soft reset a Samsung TV:

By using a Samsung TV remote.
By unplugging the TV from the power socket.

To soft reset a Samsung TV using a remote:

Press and hold the power button.
Hold it for about 5 seconds or until the TV turns OFF and ON once.

Important note: This method may vary depending on your Samsung TV model. Make sure to review your user’s manual as well.

To soft reset a Samsung TV by unplugging:

Ensure that your TV is powered ON.
Unplug the TV from the power socket for about 30 seconds.
Replug and turn ON the TV.

#2: Soft reset the WiFi router

Ah, the router… It just sits there on the shelf. You’d think it wouldn’t cause you any trouble.

However, it experiences glitches.

How come?!

Well, WiFi routers have a whole system of their own.

Which can run into some errors as well. Causing your internet connection to disconnect or become unstable sometimes.

Unlike software bugs, you can easily resolve router glitches by restarting your device.

That said, you should soft reset your router once your TV randomly disconnects to WiFi.

To soft reset a WiFi router:

Ensure that your router is powered ON.
Unplug the router from the power socket.
Wait for 15 to 30 seconds.
Replug the power cable and power ON the router.

Bear in mind soft resetting your router will temporarily disconnect your connected devices.

Just wait for the router to reboot and automatically reconnect with your devices.

#3: Update the TV firmware

Have you soft reset your TV and router already?

But your Samsung TV continues to disconnect to WiFi?

Then, probably your TV’s firmware is outdated.

Unlikely regular TVs, smart TVs like Samsung’s have firmware that run the apps on your device.

And you have to keep them updated to ensure fast and glitch-free streaming sessions.

Updating the TV’s firmware renews or upgrades its system. Ensuring that your TV has a stable connection to devices, including your WiFi router.

So, make sure to always keep your Samsung TV’s firmware up-to-date.

You can update your Samsung TV in 2 ways:

Via USB.
Via internet.

To update a Samsung TV via the internet:

#5: Connect to a 2.4GHz network

Still not working?

Then perhaps your Samsung TV is connected to a 5GHz band WiFi network.

Well, it’s not entirely bad…

But not a lot of Samsung TVs support 5GHz networks. Not to mention that it also has a pretty shorter range compared to a 2.4GHz network.

So, if you’re using a 5GHz network and your TV is far from the router, high chances are your TV won’t stay connected from WiFi.

“How would I know if my Samsung TV supports a 5GHz network?”

Usually, it’s stated in your user’s manual.

But it’s no secret that 2018 and below Samsung TVs don’t support 5GHz bands. So, take that as a guide as well.

Pro tip: If you’re using a dual-band router and your TV switches to both networks, rename or turn off the 5GHz network.

Doing this will ensure that your Samsung TV will only connect to your 2.4Ghz network.

To do this, you have to access your router account on the internet and change its settings.

The procedure depends on your ISP. So, review your user’s manual or contact your ISP’s support.

#6: Switch to using an Ethernet connection

If you don’t mind using a wired connection, switch to an Ethernet connection.

It means connecting your Samsung TV directly to your WiFi router.

Doing this will ensure:

Stable connection at all times.
Faster and glitch-free streaming.

Plus, you can also use a 5GHz network faster internet connection.

But bear in mind that your Samsung TV needs to be close to your router since you’ll be using a cable to connect it.

This is ideal for those who frequently watch movies on streaming apps like Netflix or Hulu.

As these streaming platforms require faster internet connection.

#7: Install a WiFi repeater

“Nuh, uh! Wired connection isn’t an option for me.”

Well then, consider installing WiFi repeaters.

A WiFi repeater helps distribute stable internet to other parts of your house. Ensuring that your WiFi reaches out-of-range locations.

This is ideal if your Samsung TV is on a different floor to your router.

Installing a WiFi repeater is easy. But there are some things that you should consider, especially its location.

Distance, physical barriers, and interference are factors that mostly affect WiFi stability.

That said, you should properly plan out where to position it.

To ensure stable WiFi connection, position your WiFi repeater:

In an open space.
Never inside a cabinet.
Near your Samsung TV.
Away from huge appliances and furniture.
Far from appliances that use electromagnetic waves.

#8: Factory reset the WiFi router

If nothing above works, consider factory resetting your WiFI router.

Doing this deletes data from your router. And that includes custom settings, glitches, and software bugs.

Which helps refresh the connection between your TV and WiFi.

The process depends on your ISP and your router model. So, review your user’s manual.

But usually, you just have to press the “Reset” button on the back of the router. Or use a paperclip to access the reset hole.

Important note: It’ll disconnect connected devices as well. So, you have to reconnect devices after the process.

To reconnect your Samsung TV to WiFi, follow the same process mentioned in item #4.

#10: Create a guest WiFi network

Sometimes low internet bandwidth plays a role in why your Samsung TV disconnects to WiFi.

When too many devices connect to one network, some devices like your TV may fail to connect.

This is because each device fights to receive the amount of bandwidth they need to work.

Disconnecting other devices to the network may look like the best option.

But did you know that you can create a guest network entirely for your Samsung TV?

That way, your TV won’t have to fight to receive enough bandwidth for it to work. Meaning, you can experience uninterrupted streaming with it.

What a smart move, isn’t it?

To create a guest WiFi network:

Enter your IP address to any browser.
Log into your router account.
Look for the guest network settings.
Tick or toggle on the guest WiFi access option.
Set your desired network name and password.
Click “Save.”

Note: Not all routers allow the creation of guest networks. So, contact your ISP first so as not to waste time.

#11: Enable UPnP on the router

Another solution you can try is enabling the UPnP on your router.

By default, UPnP is enabled in routers. But some users disable it for privacy reasons.

UPnP helps your devices find and connect with each other easily.

So when it’s disabled, your Samsung TV may struggle to find your WiFi network. Causing it to disconnect.

That said, you should check whether the UPnP on your router is enabled.

To enable UPnP:

Enter your IP address to any browser.
Log into your router account.
Search for and click Advanced > Advanced Setup/Network > UPnP.
Tick the box next to “Turn UPnP On.”
Click “Apply.”

Note: The steps may vary depending on your ISP. So, review your user’s manual or contact your ISP’s support.

BONUS: Change DNS server

Last but not the least, change your network’s DNS.

In simple terms, DNS is a system that helps you easily connect to websites or services on your Samsung TV.

Meaning, it can also contribute to the speed of the apps on your Samsung TV.

There are many public DNS servers out there. And you have the freedom to choose which one to use.

But you have to be careful as some may compromise your privacy.

Some of the best and most trusted ones are:

Quad9: 9.9.9.9 and 149.112.112.112.
Cloudflare 1.1.1.1: 1.1.1.1 and 1.0.0.1
Google Public DNS: 8.8.8.8 and 8.8.4.4
Cisco OpenDNS: 208.67.222.222 and 208.67.220.220

To change your DNS server:

Using a remote, press “Menu.”
Click Network > Network Status > IP settings > DNS settings.
From the options, select “Enter Manually.”
Enter your desired DNS server.
Press “OK” to save.

After this, check whether the WiFi connection on your Samsung TV has improved.

If not, try the other trusted DNS servers.
