Reasons For Samsung TV Wi-Fi Disconnection

include Network interference from other devices, Weak Wi-Fi signal, Outdated software and Network settings issues.

Network Interference From Other Devices

One of the common reasons why Samsung TV users often experience Wi-Fi connection issues are due to interference from other devices. Electronic items like cordless phones, microwaves that run on specific frequencies and even your own home’s walls can interfere with the signal strength and cause a disconnection or make it hard for your TV to establish a stable wireless connection.

Home networks sometimes overlap each other too, when more electronics in nearby homes use similar channels as yours, which causes dropouts in signal power due to conflicting data streams.

Weak Wi-Fi Signal

A weak Wi-Fi signal can be a major source of frustration when watching television, especially if you have invested in a Samsung Smart TV. The further away your wireless router is from the television, the lower the signal strength will be.

Obstructions such as walls also impact on the performance of your Wi-Fi signal; and if other devices are connected to the same network this can cause interference. If these issues limit connection strength then you might experience problems streaming or seeing a buffering sign whenever content begins loading.

Outdated Software

Updating the software on your Samsung TV can be an effective way to prevent Wi-Fi disconnections.

Outdated or old firmware versions may cause compatibility issues between hardware devices and interfere with the stability of your WiFi connection.

To avoid this, you need to frequently check for updates and ensure that the latest version is installed on your Samsung TV. The update process can be initiated manually through Menu Settings or via the manufacturer’s website – simply select ‘System Update’ in Menu Settings as it will detect if a newer version is available online.

Network Settings Issues

To start troubleshooting, know that it’s important to first reset the network settings on your Samsung TV in order to try and reconnect. Navigate to Settings, General, Network, and select Reset Network Settings upon which you will need to enter your current password before confirming the reset command.

This should generally help resolve connectivity problems or fix any related errors that may exist with regards to network settings recognition by the smart tv.

Troubleshooting Steps To Fix Samsung TV Internet Or Wi-Fi Connection Problems

Restart The Wi-Fi Router

Restarting the Wi-Fi router is an effective way to resolve many Samsung TV connectivity issues. To do this, turn off all electrical appliances connected to your router and disconnect the power cable from the back of the device.

Wait for approximately 10 minutes before plugging it back in and turning linked appliances back on.

On successful restart, you can try reconnecting your Samsung TV with your WiFi network as usual.

You should also ensure that correct settings are used while configuring a connection between devices such as inputting valid SSID password or setting static IP address if applicable.

Reset Network Settings On The TV

Resetting the network settings on a Samsung TV can help resolve many connectivity issues. To do this, users need to go to Settings > General > Network from their home screen.

Then, select Connection and then Reset Network. This will reset all of the hardware data related to networking in their TV, including any passwords for wireless networks that have been stored onto the device or other relevant information about routers and other network-related elements.

Disable IPv6 On The TV

Disabling this protocol can help improve connectivity and reduce disconnected sessions from happening frequently because it allows devices and networks on a network to operate more efficiently.

To turn off IPv6 on your Samsung TV, go to Network Settings > General > IP Setting then select “IPv4” as the connection type. You may need to restart your network devices for these settings to take effect.

Update Software

Updating the software on your Samsung TV can often be a helpful step in troubleshooting when you’re having problems with your Wi-Fi connection.

Software updates released by Samsung can address existing issues as well as provide new features and improvements, all of which are designed to help improve the functionality and performance of their tech.

Many Wi-FI connectivity issues, like dropped or slow connections, can arise from outdated software because devices communicate differently over networks depending on their up to date compatibility with one another.

Use Ethernet Connection

Using an Ethernet connection for your Samsung Smart TV can help resolve Wi-Fi disconnection issues and offer a more reliable connection than wireless networks.

By plugging one end of an Ethernet cable into the LAN port on the back of your TV, and then simply connecting it to your router’s available port, you can ensure that you have a strong, uninterrupted internet connection for streaming favorite shows or playing online games.

Compared to using Wi-Fi signals which are subject to common interference from other components in our home such as phones, computers or Bluetooth devices, hardwiring with cables is simpler and comes without potential slowdown due to radio waves congesting the airwaves.

This means even network’s slower than 50Mbps upload speed will be enough to stream High Definition content.

Despite this significant advantage over wireless options though, there may be some drawbacks when using an ethernet cabled setup like having clutter wires across furniture & walls posing tripping hazards as well as not allowing multiple TVs that share just one LAN point in larger households.

Check Wi-Fi Signal Strength

It’s important to check the strength of your Wi-Fi signal on a Samsung Smart TV, as a weak Wi-Fi signal can cause problems with streaming and lag. To check the signal strength of your Smart TV, go to Settings > General > Network > Open Network Settings> Wireless.

Here you’ll be able to see the current connection status and strength on a scale from 1-5 bars.

If your connection is weak or intermittent, you may need to adjust it by moving your router closer to the Smart TV or placing an extender in between them for better coverage across your network.

Taking these steps is especially imperative if other devices (like smartphones) are also having trouble connecting via Wi-Fi in that same room or area of the home.

Make sure you position your television closer to where your WiFi router is located. 

Turn Off Other Devices Using Wi-Fi

Multiple devices connecting to your home’s wireless network can take up all of its bandwidth. This leads to an overall weaker signal, which will eventually cause disconnections for flat panel displays like smart TVs.

Some of the most likely suspects are gaming consoles, streaming media players, cell phones, tablets or laptops that haven’t been turned off or put in airplane mode after use (which turns off WiFi).

When multiple people are trying to access data over the same Wi-Fi router at once, it can easily saturate it with user requests beyond what was designed for – resulting in frequent interruptions and instability due loosing signal strength.

It’s not always easy but you can ease these problems by turning off other devices when you aren’t using them ESPECIALLY if they share your internet connection with others who might also be accessing data intensive activities like downloading large files during peak times OR playing online games since those require a lot of resources (bandwidth+ ping/latency) as well which might lessen responsiveness even more so when attempting light browsing activities like watching Netflix movies or videos etc! It’s recommended that everyone shares information between each device manufacturer about what types could possibly interfere with optimal performance before purchasing new items.

Install A Wi-Fi Extender Or Mesh System

Installing a Wi-Fi extender or Mesh System can be an effective way of solving Samsung TV Wi-Fi disconnections. These devices act as a booster, amplifying your existing signal and extending it to previously unreachable areas of the home.

This eliminates any dead zones in the house, providing stronger coverage throughout all rooms, improving both the performance and reliability of your network connection. 

Check For App Issues

It is important to ensure that apps related to streaming on the Samsung TV are running properly and not causing issues. If some of your favorite show’s app keeps crashing or you notice choppy performance, then it may be due to problems with the cache or data stored in the app.

To fix this issue, try clearing cache and data for the faulty app by going into Settings – Apps – App name – Clear Cache/Clear Data. You should also make sure the troublesome app is installed correctly and check if there are any updates available.

It might help reinstalling it again if all other methods don’t work—be sure to back up your content first!

Some common culprits include Netflix, Hulu, Amazon Prime Video, Disney+, and Sling TV apps which typically cause intermittent WiFi disconnections when errors occur within them.

Reset Wi-Fi Settings On The TV

Navigate to Settings on your Samsung TV, go into Network Settings, and then scroll down until you see Resetting Wireless Never (This will usually be in the Advanced Settings tab).

Follow the steps onscreen carefully as instructed; doing so will reset all wireless network settings back to factory defaults.

It’s important that during this process, you don’t turn off or unplug your television at any point.

If successful, when finished your Samsung TV should automatically begin searching for nearby Wi-Fi networks which can be connected by entering their associated passwords.

This works great if other troubleshooting methods like restarting the wireless router fail to help with reconnecting successfully over WiFi.


Troubleshooting Wi-Fi disconnection issues on Samsung TVs can be tricky, but there are simple solutions and steps to follow. Firstly, it’s important to check the internet speed and signal strength from a router nearby.

Try using a wired connection or installing a Wi-Fi extender or Mesh System.

Additionally, updating the software of the TV can resolve many issues; if not then resetting all network settings is highly recommended.

These steps should help users fix most software related problems that cause Samsung TVs to keep disconnecting from Wi-Fi networks.
