I have an LG tv with a netcast option on the remote, however, i do not know how to connect the internet/ethernet to the tv so that i can go on youtube. when i press enter on youtube, a notice pops up that says, "network is disconnected", how do i connect the network so that i can go on youtube? also, i don't know where the ethernet port is on the tv, so if someone could help me with that too it would be greatly appreciated
