Read on to learn why your Samsung TV keeps disconnecting from WiFi and how to finally stop the constant dropping of wireless signal.

Common Causes of Samsung TV Disconnecting from WiFi

There are a few typical culprits that can explain why WiFi connectivity is unreliable on your Samsung television.

Outdated software – If it’s been a while since you updated the firmware on your Samsung TV, lack of compatibility with your wireless router could cause WiFi dropping issues.

Weak wireless signal – If your WiFi router is too far from your Samsung TV or there are obstacles blocking the signal, it may struggle to maintain a consistent connection.

Incorrect network settings – Your Samsung TV may have incorrect WiFi settings that are causing conflicts with your wireless network and making the connection drop.

Faulty WiFi adapter – In rare cases, the internal WiFi adapter on the Samsung TV could be defective and responsible for frequent disconnections from the network.

Interference from other devices – Signals from Bluetooth devices, microwaves, baby monitors and more can potentially interfere with and disrupt the WiFi signal between your router and TV.

The problem also tends to happen more frequently on Samsung TV models that only have a single antenna for receiving WiFi signals. Dual antenna Samsung TVs are usually more reliable for maintaining wireless connectivity.

Step-by-Step Troubleshooting for Samsung TV WiFi Issues

If you notice your Samsung TV is having difficulty staying connected to the internet via WiFi, don’t panic. Here is a step-by-step troubleshooting guide to help identify and resolve the issue:

Restart Your Samsung TV and Router

Often a simple restart of both devices is enough to fix temporary glitches in communication over WiFi.

Unplug your Samsung TV and WiFi router from power. Wait 30 seconds.
Plug them both back in and give a few minutes for connection to reestablish.

This “soft reset” clears any software errors and reinitializes communication over the wireless network.

Verify Router Internet Connectivity on Other Devices

To isolate whether the problem is with your Samsung TV or with general WiFi coverage, check internet connectivity from other devices like laptops, phones or tablets connected to the same wireless router.

Connect another device to your WiFi router.
Run a speed test and browse the internet to confirm connectivity is working fine.

If other devices have internet access over WiFi as normal, your Samsung TV likely has an issue. If the router has no connectivity across multiple devices, contact your ISP for troubleshooting.

Analyze Samsung TV Wireless Signal Strength

Weak WiFi signal can manifest as frequent drops in connectivity. Check how many bars your Samsung TV is receiving from your wireless router.

Go to Settings > General > Network > Open Network Settings > Wireless
Look at the WiFi signal strength shown in bars on your TV.

If you see only one or two bars, the router needs to be moved closer to improve signal to the TV. Walls, floors and interference from other electronics can degrade WiFi signal over distance.

Update Samsung TV Software and Firmware

Outdated software is a common source of wireless connectivity problems. Newer firmware versions improve stability and compatibility with routers.

On your computer, find your exact Samsung TV model on the Samsung support site.
Download the latest firmware update for your model to a USB flash drive.
With TV powered off, insert the USB drive into a port on the TV.
Turn on your Samsung TV and install the firmware update from the USB.

Updating to the newest firmware is an important troubleshooting step before further WiFi fixes.

Reset Your Samsung TV’s Network Settings

If your wireless settings have errors or are misconfigured, resetting the network settings may help.

Go to Settings > General > Network on your Samsung TV
Select Reset Network and confirm reset when prompted
Re-enter your WiFi network password to reconnect

This clears any bad settings and forces the TV to freshly establish the WiFi connection.

Move the Router Closer to Your Samsung TV

Distance and obstacles between your WiFi router and Samsung TV can contribute to wireless connectivity problems.

If possible, move your wireless router to be in the same room as your Samsung TV.
Position the router out in the open, in direct line of sight with your TV.
Keep the router away from other electronics, appliances and metal objects.

Closer proximity between your router and TV will provide a stronger signal without interference.

Connect Samsung TV to Router Via Ethernet Cable

For the most reliable connectivity, use an ethernet cable to connect your smart TV directly to your wireless router.

Connect one end of an ethernet cable to the LAN port on your router.
Connect the other end to the ethernet/LAN port on the back of your Samsung TV.
On your TV, go to Settings > General > Network and ensure it is configured for a wired ethernet connection.

Ethernet provides faster speeds and more stable connectivity than WiFi, eliminating wireless signal issues.

Perform a Factory Reset on the Samsung TV

If all else fails, reset your Samsung TV to factory default settings in case of any software bugs disrupting the WiFi connectivity.

From the Samsung TV menu, go to Settings > General > Reset
Enter your PIN code if prompted (default is 0000)
Select Reset to confirm factory reset

This will erase all your data, apps and settings. You’ll have to reinstall apps and set up WiFi again after the reset completes.

When to Call a Samsung TV Technician

If you’ve worked through all troubleshooting steps and your Samsung TV still won’t stay connected to your WiFi network, it’s time to get an expert involved for repairs. A technician can:

Diagnose hardware issues like faulty network adapters
Test signal strength and interference in your room
Update firmware and factory reset if you’re unable to
Replace any defective components responsible for WiFi dropping

For Samsung TVs under warranty, WiFi connectivity problems may be covered as a manufacturer defect. Get in touch with Samsung support about warranty repairs.

If your warranty has expired, contact a third party electronics repair technician certified to service Samsung TVs. They can visit your home to properly inspect your Samsung TV and recommend the right solution whether it’s a software fix or hardware replacement needed.

Investing in professional repairs can seem expensive but often costs significantly less than buying a brand new replacement Samsung Smart TV. The repair also salvages your existing TV with custom configuration rather than starting over from scratch.

DIY Troubleshooting Tips to Stop Samsung TV Disconnecting from WiFi

Before hauling your malfunctioning Samsung TV away or paying for technician visits, try using these DIY troubleshooting tips to identify and resolve what’s causing the WiFi connectivity problems yourself:

Update your Samsung TV firmware – Older firmware versions tend to have more WiFi bugs and compatibility issues with newer routers. Find firmware updates for your exact model on the Samsung support site.
Change WiFi frequency band – If other households nearby are crowding the 2.4GHz band, switch your wireless router and Samsung TV to the cleaner 5GHz frequency band.
Adjust router channel setting – Try switching your wireless router to a less congested WiFi channel away from neighboring networks. Channels 1, 6 or 11 are generally recommended.
Disable Samsung TV wireless power saving – Turn off any settings like Power Saving Mode that put the WiFi adapter to sleep and cause dropping connectivity.
Forget then re-enter WiFi password – Deleting your wireless network connection and re-entering the password forces a fresh authentication that may resolve glitches.
Disable router firewall and security temporarily – Some routers and security software can interfere with connectivity. Temporarily turning them off can help pinpoint the cause.
Plug Samsung TV into router via ethernet – Wired ethernet connection is generally faster and more reliable than using WiFi to your smart TV.
Relocate router closer to TV with clear line of sight – Distance, walls and objects blocking signal will degrade WiFi connectivity and cause drops.
Scan area for interference from baby monitors, microwaves etc – Devices operating on similar radio frequencies as WiFi can interfere with and disrupt wireless signals.
