Check What Is Causing the Problem
When your Samsung Smart TV loses Wi-Fi connectivity or refuses to connect at all, the cause is rarely a single fault. Before jumping into complex settings, take a moment to understand where the breakdown is happening. A simple check can save you time.
Start by testing whether the issue affects your TV alone or your whole home network. Grab a phone, tablet, or laptop and see if those devices can connect to the same Wi-Fi network and access the internet. If they work normally, the problem is almost certainly with the TV or its connection to your router. If other devices also have trouble, the issue lies with your internet service, your router, or your modem.
Also note whether the TV shows any specific error message. Some Samsung TVs display messages like “Network connection unstable” or “Wi-Fi password incorrect.” Others simply show an empty network list or fail to complete a connection test. The exact wording can help narrow down the next step.
Fixes to Try in Order
These fixes are arranged from the simplest and safest to more involved steps. Try them in order and test your connection after each one.
1. Restart the TV and the Router
This is the most common fix and resolves a surprising number of connectivity problems. Turn off your Samsung TV using the remote. Unplug the TV power cord from the wall outlet. At the same time, unplug your router and modem (if they are separate devices). Wait at least 60 seconds. Plug the router and modem back in first and wait until all lights show a normal online state. Then plug the TV back in and turn it on. Try connecting to Wi-Fi again.
This clears temporary network glitches on both the TV and the router. The full minute of being powered off ensures that internal memory in both devices is fully reset.
2. Check the Wi-Fi Network and Password
If the TV sees available networks but cannot connect, the password is the most likely culprit. Samsung TVs store network credentials, but a password change on the router or a typo during entry will block the connection. Go to the TV’s network settings and select your network. Choose the option to “Forget” or “Delete” the network. Re-enter the Wi-Fi password carefully, paying attention to uppercase and lowercase letters. If possible, change the password display setting to “Show characters” so you can verify each character.
If your router uses a hidden SSID (network name that does not broadcast), the TV may not list it. In that case, select the option to “Add Network” and enter the network name and password manually.
3. Move the TV Closer to the Router or Reduce Interference
Wi-Fi signals weaken with distance and obstacles. Walls, metal appliances, fish tanks, and even large furniture can block or degrade the signal. If your TV is far from the router, try moving it temporarily closer to see if the connection improves. If that is not practical, consider the placement of the router. Raising it off the floor and away from electronic devices can help. For a permanent solution, a wired Ethernet connection is the most reliable option if your TV has an Ethernet port and you can run a cable.
4. Change the Wi-Fi Band
Most modern Samsung Smart TVs support both the 2.4 GHz and 5 GHz Wi-Fi bands. The 2.4 GHz band travels farther and passes through walls better but is more prone to interference. The 5 GHz band offers faster speeds but has a shorter range. If your router broadcasts both bands under the same network name (often called “band steering”), the TV may pick the weaker band. Try separating the bands in your router settings by giving them different network names (for example, “MyNetwork-2G” and “MyNetwork-5G”). Then connect the TV to the band that works best in its location.
Note that the menu for changing this setting lives in your router’s administration interface, not on the TV itself. Consult your router’s manual for instructions on renaming SSIDs.
5. Update the TV Software
Outdated firmware can cause compatibility issues with newer router security standards or Wi-Fi protocols. Samsung TVs typically check for updates automatically, but you can force a check manually. Go to the TV’s settings menu, navigate to “Support” or “General,” then select “Software Update.” Choose “Update Now” or “Check for Updates.” If an update is available, install it. The TV will restart during the process. After the update, test the Wi-Fi connection again.
If the TV cannot connect to the internet at all to download the update, you can download the update file from Samsung’s support website using a computer, save it to a USB drive, and install it via the TV’s USB port. Check Samsung’s support page for your specific TV model for instructions on this method.
6. Reset the Network Settings on the TV
Resetting network settings clears all saved Wi-Fi networks, passwords, and custom network configurations on the TV. It does not erase your apps, account logins, or picture settings. Go to the TV’s settings, look for “General” or “Network,” then find “Reset Network” or “Network Reset.” Confirm the action. The TV will restart and you will need to set up the Wi-Fi connection from scratch, including entering the password again.
7. Change the Router’s Security Settings
Some older Samsung TVs have trouble connecting to routers that use the newer WPA3 security standard. If your router is set to WPA3 or to a mixed WPA2/WPA3 mode, try changing it to WPA2 (sometimes labeled as WPA2-PSK or WPA2-AES). This change is made in the router’s wireless security settings. Keep in mind that this lowers the security level of your Wi-Fi network slightly, but WPA2 remains widely considered safe for home use. After changing the setting, save it and reconnect the TV.
8. Set a Static IP Address on the TV
If the TV connects to the network but fails to obtain an IP address automatically (you may see an error about IP configuration), assigning a static IP address can help. On the TV, go to network settings and choose “Advanced” or “IP Settings.” Switch from “Automatic” to “Manual” or “Static.” You will need to enter an IP address, subnet mask, gateway (usually your router’s IP address), and DNS server addresses. Without the correct information, this can break your connection, so use this step only if you are comfortable with basic networking. A simpler alternative is to set an IP address reservation for the TV in your router’s DHCP settings, which achieves the same result without entering numbers on the TV itself.
9. Check for Interference from USB Devices
A lesser-known cause of Wi-Fi problems on Samsung TVs is interference from devices plugged into the TV’s USB ports. External hard drives, USB hubs, or even charging cables can generate electrical noise that interferes with the internal Wi-Fi module. Unplug all USB devices from the TV and test the Wi-Fi. If the connection improves, you may need to move USB devices away from the TV or use shielded cables.
If the Problem Continues
If none of the above steps restore Wi-Fi connectivity, the issue may be hardware-related. The internal Wi-Fi module in the TV can fail over time, especially in older models. Before concluding that the hardware is faulty, try connecting the TV to the internet via a wired Ethernet cable if an Ethernet port is available. If wired internet works but Wi-Fi does not, the wireless module is likely the problem.
Another option is to use an external streaming device such as a Roku, Apple TV, or Amazon Fire Stick that connects to Wi-Fi independently. This bypasses the TV’s internal Wi-Fi entirely. While this adds a device and an HDMI port, it is often cheaper and simpler than repairing the TV.
If the TV is still under warranty, contact Samsung support for repair or replacement. Out-of-warranty repairs for a Wi-Fi module can cost as much as a new entry-level TV, so weigh the cost before proceeding. You can find the model number of your TV on the label on the back of the unit or in the settings menu under “Support” or “About This TV.”
Frequently Asked Questions
Why does my Samsung TV keep disconnecting from Wi-Fi?
Intermittent disconnections are often caused by weak signal strength, network congestion, or interference from nearby electronics. Try moving the router closer, changing the Wi-Fi channel in the router settings, or switching between the 2.4 GHz and 5 GHz bands. Restarting both the TV and router can also resolve temporary disconnects.
Will a factory reset fix my Wi-Fi issue?
A factory reset restores the TV to its original out-of-box state, which can resolve persistent software-related network issues. However, it also erases all installed apps, account logins, and personalized settings. Try the other fixes first, and use a factory reset only as a last resort. The option is usually found under Settings > General > Reset.
Can a VPN or DNS change help with Wi-Fi problems?
Changing the DNS server on the TV to a public DNS like Google DNS (8.8.8.8 and 8.8.4.4) can sometimes improve connection reliability if your ISP’s DNS is slow. However, this does not fix a weak signal or a hardware fault. A VPN configured on the TV can actually slow down the connection or cause compatibility issues with streaming services.
Does Samsung offer a warranty for Wi-Fi issues?
Samsung’s standard warranty covers hardware defects, including a faulty Wi-Fi module, for a limited period (typically one year from the purchase date in the US). Software-related issues are not covered by warranty but can usually be resolved with updates or settings adjustments. Check your purchase receipt and Samsung’s warranty terms for your region.
