|Check your computer's TCP/IP (network) settings. Is it set to get it's TCP/IP settings automatically (DHCP) or do they have to be manually assigned?|
If manual, make note of the present settings on the TV. Then one a computer connected to your router that is working properly, open a command prompt window (ie: Start >> Run >> type cmd and hit Enter) and perform the following command:
Compare the output of the two devices and post the IP Address of each in here so I can compare too. I suspect your new router may be using a different subnet than the old one and the TV in question may be configured for the old subnet. We'll know more once I see the two IP's.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
