I just got my Samsung UN46D6400 set today. I hooked it directly to my modem to check the ethernet setting. Under network, I hit wired setup. It says that it failed. I get a MAC address and IP address, but it says that DHCP is not enabled. When I called Comcast, they said that the IP address was wrong. They said it is a TV set issue. Nothing to do with ISP. Does anyone know how to fix this? Thanks.
