192.168.0.101 are different addresses on the same network.
• Make sure the TV IP address is on the same subnet as the
networked PC.

192.168.0.100 with the Sub
net mask 255.255.255.0, the TV
has the IP address 192.168.0.101 with the Subnet mask
255.255.255.0; both are on the same subnet.
Example of improper setup: The PC has the IP address
192.168.1.100 with the Subnet mask 255.255.255.0, the TV
has the IP address 192.168.0.101 with the Subnet mask
255.255.253.0; they are on different sub-nets.
