What should I do if my TV is not connecting to a wired network?

Go to Menu > Settings > All Settings > Connection > Network > Open Network Settings > Wired; when a LAN cable is connected, the TV should access the network automatically. Samsung recommends using a CAT 7 (STP type) cable for the connection (100/10 Mbps), and note that the TV will not be able to connect if your network speed is below 10 Mbps. If the TV still does not connect, refer to the 'Wired network connection failed' section in Troubleshooting. (Page 9)
