To connect your Samsung TV to the internet, you'll need an Ethernet cable or a Wi-Fi connection. If you choose to use an Ethernet cable, make sure it's long enough to reach from your TV to your modem or router. Simply plug one end of the cable into the LAN port on the back of your TV and the other end into the Ethernet port on your modem or router.
If you prefer a wireless connection, make sure your TV is within range of your Wi-Fi router. On your TV, go to the settings menu and select the network option. From there, choose Wi-Fi, and the TV will display a list of available networks. Select your Wi-Fi network and enter the password if prompted.
Once connected, your Samsung TV will be able to access the internet and stream online content, browse the web, and use various smart features.
