This article will provide a set of proven solutions to address this issue, along with possible reasons why the WiFi feature on the TV might be malfunctioning.
What Prevents Samsung Televisions from Connecting to WiFi?
Our investigation has revealed that there is no single cause for the problem, which can occur due to various reasons. Some of the most prominent causes include:
Outdated Firmware: A televisions firmware that hasnt been updated to the latest version might not function correctly. The TV needs the newest firmware to make sure all settings are appropriately configured based on the region.General Bug: There have been reports of a common software bug in Samsung Smart TVs whereby, if the TV is turned off using the remote for longer than 10 to 15 minutes, network settings may become corrupted and require resetting to establish a proper connection.MAC Address Block: Each device connects to a WiFi router using a unique MAC address. Should this address be blocked—either by the user or the ISP—the TV will no longer connect to the WiFi network until the block is lifted.DNS Settings: Incorrect DNS settings on the TV can lead to conflicts with the router when attempting to connect to the internet. These settings may need to be manually adjusted by the user for the internet to function correctly.
Equipped with an understanding of why the problem occurs, we can now explore the solutions. Its recommended to follow these solutions in the order provided to prevent potential conflicts.
1. Restart the TV
Restarting your TV flushes the system memory and can resolve temporary software glitches that may be causing the Wi-Fi connectivity issues. By fully powering down the TV and unploting it for a short period, youre allowing all capacitors to discharge and all volatile memory to clear. This makes sure that when you turn the TV back on, it starts fresh, which can lead to restoring a stable connection to your WiFi network.
2. Restart the Internet
The issue might lie with the internet connectivity or incorrect DNS settings of the router, preventing the TV from accessing the internet. Restarting the internet can clear any glitches in the routers memory, refresh your connection to your Internet Service Provider (ISP), and resolve IP conflicts between your devices, which in turn could re-establish your TVs WiFi connection.
3. Change the Internet Connection
By attempting to connect your TV to an alternative network, such as your smartphones mobile hotspot, you can discern if the original WiFi connection is the source of the problem. If the TV connects to the hotspot without issues, it implies that your usual WiFi network might be blocking the TV’s MAC address or facing other specific connectivity barriers that do not affect other devices. This allows you to take the necessary steps, such a contacting with your ISP or adjusting router settings, to resolve the connectivity issue on your primary network.
4. Firmware Update
Bascially, the firmware is the software that looks over how your TV operates; its the critical code that controls everything from the menu interface to internet connectivity functions. By updating it, you make sure that any known bugs or glitches affecting WiFi performance are ironed out. Manufacturers routinely release updates to enhance device compatibility with newer routers, improve security, and ensure optimal functionality. So, refreshing your TVs firmware can bridge communication gaps between your TV and home network, potentially restoring that smooth streaming experience youve been missing.
5. Refresh DNS Settings
DNS, which stands for Domain Name System, is similar to a phonebook for the internet, translating human-friendly domain names into IP addresses that computers use. If the DNS settings on your TV are incorrect or outdated, it may struggle to communicate effectively with your network router, leading to connectivity issues. By refreshing these DNS settings and manually setting them to a reliable server like Googles public DNS (8.8.8.8), you realign your device with the internets directory service, potentially resolving any connection issues.
6. Perform a Hard Reboot
When you hard reboot your Samsung Smart TV, it acts as a system refresh, clearing temporary configurations that may have gone wrong. This process can potentially fix glitches that cause connectivity issues, giving your TV and its Wi-Fi functionality a fresh start. This turn it off and on again method is a timeworn troubleshooter for a reason—it often works wonders. Note: If the problem persists after trying all the solutions, it may be a hardware issue rather than a software one. In that case, contact Samsung Customer Support. Before attempting to fix the WiFi issue on your Samsung TV, make sure no accessory is connected to the TV (e.g., Firestick, Chromecast, Android Streaming Box, Soundbar, WiFi Extender, Xbox, Blu-ray, DVD player, etc.). It is also advisable to remove extra devices from the network (like network storage devices). Furthermore, check if connecting the TV without a surge protector or to a power source in another room, or using a different power adapter, resolves the issue.
7. Edit the TV Settings
If the TV still experiences issues, incorrect configuration of the Samsung TV’s settings might be the cause—particularly if it fails to connect even to a phone hotspot. Users may find success with the following settings, though note that instructions may vary slightly between users.
Refresh Resources in the Smart Hub
Change the TV Name
Reset Network Settings of the TV and Disable IPV6
Disable Power On with Mobile
Disable Samsung Instant On
Set the Usage Mode to Home
Disable Auto Launch Last App and Autorun Smart Hub
Disable the AnyNet+ Feature
Change the Time Zone of Your TV
Disable the Soft AP Option
Manually Change the IP Address of Your TV
Reset the Smart Hub of Your TV to Defaults
Change the Country of Your TV
Change the Wi-Fi Region and Perform an SVC Reset
If these steps do not resolve the issue, a Factory Reset of Your TV may be necessary.

8. Edit the Router Settings
If your TV connects properly using a mobile hotspot, then the issue is likely due to incorrect router configuration. Consider adjusting the following settings, which have helped other users resolve similar issues: Should the issue still persist, consider using an Ethernet cable to connect to the internet, or have the TV inspected for hardware problems. In some cases, as reported by a few users, replacing the Wi-Fi module fixes the problem, although in rare situations, the mainboard of the TV may need to be replaced.
