Let’s check how to fix Wi-Fi not working on Samsung Smart TV.

1. Restart Samsung TV
The first thing that you must do if your Samsung smart TV isn’t connecting to Wi-Fi is to restart your Smart TV. There are two ways to do so.
In the first method, you need to unplug the TV from the power source and keep it disconnected for at least up to 60 seconds. Then, plug the power cord back into the plug. Your TV will turn on. Again, wait for a minute until the TV boots up fully. Hopefully, the Wi-Fi should start working on your Samsung TV now.
Alternatively, if the idea of unplugging the TV from the power supply seems too laborious, you can use the Power button on your TV’s remote to restart the TV. Basically, with your TV turned on, press and hold the Power button on your remote until the TV turns off and on automatically. Leave the button when you see Samsung Smart TV written on the screen. Wait for a minute before you start using the TV. Meanwhile, the TV will connect to the Wi-Fi.
2. Restart Modem
Next, you should also restart your Wi-Fi modem. To do so, simply, unplug the Wi-Fi modem from the power source. Many times, the first two solutions are enough to fix Wi-Fi issues on Samsung Smart TV.
3. Check Wi-Fi Password
If it’s the first time you are connecting to the Wi-Fi on your Samsung Smart TV, make sure you are typing the correct password for your Wi-Fi. So, when the on-screen keyboard appears, enable the checkbox next to Show password. This will ensure that you are typing the right password.
Pro Tip: You can also use the SmartThings app on your phone to type the password.
4. Reduce the Number of Devices Connected to Wi-Fi
Most Wi-Fi modems have a limit on the number of devices that can connect to them. The more devices you have connected to a particular Wi-Fi network, the weaker its signal will become. So, if you are experiencing an internet issue on your Samsung TV, you should disconnect some other devices that are connected to your Wi-Fi network.
5. Connect to 2.4GHz
Another simple solution to fix the Wi-Fi issue on Samsung TV is to connect to the 2.4GHz network instead of 5Ghz. Basically, if you see two Wi-Fi connections, connect to the one that says 2.4Ghz.
6. Re-add Wi-Fi Network
You should also try to forget the Wi-Fi network on your TV and re-add it to fix Wi-Fi not working issue.

3. Then, go to Open network settings.
4. Select Wireless.

6. Select the network that you want to delete and then press the Delete option.
7. With the Wi-Fi network deleted, follow steps 1-4 again until you the Wireless Connection screen. Select the Wi-Fi to which you want to connect and enter the password. Hopefully, Wi-Fi will start working on your TV.
7. Keep TV Near Router
If Wi-Fi keeps disconnecting or you are unable to see the Wi-Fi network on your Samsung TV, make sure that the TV and modem are within the compatible range.
You can check the network strength by going to Settings > General > Network > Open network settings > Wireless. Here you will see the available Wi-Fi networks. The Wi-Fi network that you are connected to will show a checkmark icon next to it. Check the number of Wi-Fi bars that show next to the network. More bars indicate a better network.
