In this article, we will provide you with a set of solutions that have been tested to solve the problem for most of our users. Also, we will provide you with the reasons due to which the Wifi feature of the TV might be malfunctioning.

What Prevents Samsung Television from Connecting to the Wifi?

According to our investigation, the cause of the problem is not specific and it can occur due to a number of reasons. Some of the most notable ones are:

  • Outdated Firmware: If the firmware of your television is outdated and has not been updated to the latest version, it might not work properly because the television requires to be updated to the latest firmware in order for all the settings to be configured properly depending on the region.
  • General bug: There have been many reports of a general bug with the software of the Samsung Smart TVs where if the TV was turned off through the remote for a period longer than 10 to 15 minuter the network settings are corrupted and they need to be reset in order for the connection to work properly.
  • Mac Address Block: Every device that connects to the Wifi router uses a specific address in order to do so. Sometimes that address can be blocked from connecting to the Wifi router either by the user or by the ISP. If that is the case the TV will no longer be able to connect to that Wifi router unless the ban is lifted by the ISP.
  • DNS Settings: In some cases, the DNS settings on the TV are not properly configured and result in a conflict between the Router and the TV while trying to connect to the internet. The settings have to be changed manually by the user in order for the internet to connect properly.

Now that you have a basic understanding of the nature of the problem we will move on towards the solutions. It is recommended that you try these solutions in the specific order in which they are provided to avoid any conflicts.

Solution 1: Restarting TV

Sometimes due to a bug with the Samsung TVs, the network settings are corrupted if the TV is turned off through the remote and it stays off for more than 15 minutes. Therefore, in this step, we will be restarting the TV in an unconventional method that will reset certain settings. For that:

  1. Turn on the TV in the normal way and let it run for 5 minutes.
  2. Instead of turning it off with the remote, plug out the cable directly from the wall.
    Disconnecting Power cord
  3. Wait for a period of at least 20 minutes and restart it.
  4. Enter the Wifi password if it prompts you to enter it and check to see if the issue persists.

Solution 2: Restarting Internet

It is also possible that the internet might be facing certain issues and the Wifi service might not be functioning correctly or the DNS settings on the router might be blocking the Television from accessing the internet. Therefore, in this step, we will be completely power-cycling the Internet Router. For that:

  1. Turn off the power to the Internet Router.
  2. Wait for a period of at least 10 minutes before turning the power back on.
  3. Wait for the Router to load the internet settings, when internet access is granted try to connect the TV to the Wifi and check to see if the issue persists.

Solution 3: Changing Internet Connection

If the Mac address of the Television has been blocked by the Internet Router you will not be able to connect to the Wifi connection provided by that router. Therefore, in this step, we will be checking to see if that is the case. For that:

  1. Turn the TV on and navigate to the Wifi Settings.
  2. Grab your mobile and turn on the Hotspot.
    Turning on the mobile hotspot
  3. When the name of the hotspot provided by the mobile shows up in the available connections list, connect to that and check to see if the issue persists.
  4. If the TV is connected to the Mobile’s hotspot properly then most likely the TV’s Mac Address is blocked by the internet router.
  5. You can contact your ISP to unblock the Mac Address of the Television.

Solution 4: Firmware Update

The Firmware of the device needs to be updated to the latest version according to the TV model and the region. If the Firmware is not updated you will experience issues while trying to connect to the internet. Since you cannot connect to the internet to download the correct firmware of your device we will be doing it through a computer. For that:

  1. Open this link and select the correct model of the Samsung TV that you are using.
    Samsung Product Support Center
  2. Click on download and wait for it to finish.
  3. Extract the downloaded files to a USB that does not have any other data on it.
  4. Make sure to remove any extra symbols or numbers that your computer might have added to the downloaded file.
  5. Connect the USB to the TV and press the “Menu” button on the remote.
  6. SelectSupport” from the menu and then the “Software Upgrade” option.
  7. Now choose “By USB” from the methods of update list.
  8. Click on “OK” if the TV prompts you that a new update will be installed and wait for the process to finish.
  9. Try to connect to the Wifi and check to see if the issue persists.

Solution 5: Refreshing DNS Settings

It is possible that the DNS settings on the television are causing conflict with the internet router and preventing you from connecting to the internet. Therefore, in this step, we will be reinitializing the internet settings. For that:

  1. Press the “Menu” button on the remote and then the “Settings” button.
  2. Now select “Network” and then “Network Settings”.
  3. Click on “Start” and select “IP Settings“.
  4. Now select “DNS mode” and make sure that the green check is on the “Manual” mode and press “OK
    Navigating to the “Enter Manually” option and pressing OK
  5. Enter “8888” and press “OK
  6. Now you will get internet access if the problem was with the DNS settings and you can click on the “Samsung Smart Hub” button to automatically update the television and reset old programs.

Solution 6: Performing Hard Reboot

In some cases, you can perform a hard reboot on your TV to fix this particular issue. In order to perform a hard reboot, follow the instructions below.

  1. Get ahold of your Samsung TV remote and long-press the “Power” button.
  2. Keep the power button pressed while the TV reboots and let go if it when you see the “Samsung” logo.
  3. Check and see if rebooting like this fixes the issue.

Note: If you are still encountering the problem after trying to implement all these solutions it is possible that it might be a hardware issue and not a software one. Therefore, you will need to contact Samsung Customer Support.

Before proceeding to fix the WiFi on your Samsung TV, make sure no accessory is connected to the TV (e.g., Firestick, Chromecast, Android Streaming Box, Soundbar, Wi-Fi Extender, Xbox, Blue-ray, DVD player, etc.). Moreover, it will be a good idea to remove extra devices from the network (like a network storage device). Additionally, check if connecting the TV without the surge protector resolves the issue. Also, check if connecting the TV to a power source in another room sorts out the problem (or using a different power adapter).

Solution 8: Edit the Router Settings

If the TV connected fine when using a mobile hotspot, then the issue most probably is caused by the wrong configuration of your router settings. You may try the undermentioned configurations reported by the users to resolve the issue for you. In this article, we will just give a brief description of the reported solution, you may have to dig deeper to make it work for you.

  1. First and foremost, make sure the firmware of your router is updated to the latest build and then check if the Wi-Fi issue is sorted.
  2. Disable Nvidia Shield, PiHole, or something similar to check if that was blocking the Wi-Fi access.
  3. Check if the MAC address of the Samsung TV is not blocked in a parental control or ISP management application. Also, make sure MAC filtering of the router is not causing the issue. Moreover, check if adding the TV to the Trusted Devices in the router settings may solve the problem.
  4. If your router supports multi-band (i.e., 2.4 GHz or 5 GHz), then check if disabling one of them (preferably, using 2.4 GHz) or using different names for the bands resolves the issue.
    Disable 5GHz Band in the Router’s Settings
  5. Check if the Wi-Fi channel is not over-crowded (you can use an application to scan for the Wi-Fi channels usage in the area). If so, then switching to another Wi-Fi channel (e.g., using channel 11) may solve the problem. Also, make sure to disable Automatic Channel Switching. If you are using a 5 GHz band, then make sure you are using a non-DFS channel.
  6. Check if changing the wireless mode to Legacy, G, N, or Auto resolves the issue.
    Change Wireless Mode to Legacy
  7. Make sure that IPV6 in the router’s settings is disabled.
  8. Enable UPNP in the router settings and check if that was causing the issue.
    Enable UPnP
  9. Check if your router has a built-in firewall, if so, then disable it (proceed at your own risk as it can be a security threat) and check that it was causing the issue. If so, then make sure to exempt the resources essential for the TV from the firewall settings.
  10. If you are using a hidden SSID, then check if unhiding it solves the problem. Also, check if renaming the Wi-Fi resolves the issue.
  11. Check if your router supports the Smart Wi-Fi/Smart Connect/Smart Assistant feature, if so, then disable and check if the issue is resolved. If the said feature is already disabled, then check if enabling it resolves the issue.
  12. Check if disabling Auto-Optimize Network/Channel Optimization in the router settings clears out the problem.
    Disable Auto-Optimize Network
  13. Make sure to disable the ‘Connect High-Performance Devices to 5 GHz Only’ feature in the router’s settings.
    Disable High Performances Devices
  14. Disable Uplink Connectivity Monitor to check if that resolves the Wi-Fi issue.
    Disable Uplink Connectivity Monitor
  15. Disable Roaming Assistant to check if that clears out the Wi-Fi error.
    Disable Roaming Assistant
  16. Disable Packet Filtering and check if the issue is sorted.
    Disable Packet Filtering
  17. Make sure the WPS switch (it may flash green if working fine) of your TV is enabled and working fine. Then check if using it to connect your TV sorts out the Wi-Fi problem (you may enter the TV-generated PIN in the WPS setup).
  18. Check if changing the wireless authentication between WPA/WPA2 or WPA 3 sorts out the problem. If it fails, then check if setting the router encryption to TKIP solves the problem.
  19. If none of the above resolved the issue, then you may have to change the DHCP settings of your router (e.g., assigning a fixed IP least to the TV).
  20. Check if creating a Guest network and only connecting your Samsung TV to it sorts out the Wi-Fi problem.
    Create Guest Wi-Fi Network
  21. If none of the solutions resolved the issue, then performing the factory reset of the router may clear the error. If not, then you may have to use another router or extender (given that your TV can access the internet with the mobile phone’s hotspot).

If the issue is still there, then either use an ethernet cable to use the internet on the TV or get your TV checked for a hardware issue. Some users reported that replacing the Wi-Fi module resolved the issue but rarely, the motherboard of the TV has to be replaced.
