Network Setup fails (Auto)
• Check to ensure the LAN cables are connected properly
(- p. 22).
• DHCP is not enabled on the router, or no router is
present. Refer to your router's documentation for
instructions on enabling DHCP. If you do not have a

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