You would need to connect it to your home network - I presume you know how to do this... no? You go to Network Settings, there you select the network and enter the password.
After you connect to the network, press the Netflix button on your remote, and see if it connects there.
If not, here's what you do:
I don't know if your menu is identical to mine (our sets are a few years apart), but you go to Menu, then to Networks, then to Network Settings.
There you will see several parameters, including the DNS. Usually it is set to be Automatic, and it will show some value. You click on it, and then select: Manual. It will give you the line, where you enter the four digits, in this case 8.8.8.8.
All this might sound scary the first time around, but it is done pretty well in Samsung menu.
