Network problems

Cannot connect to the Internet

•Check the modem and its incoming cable/telephone
connections (- p. 21).
•Confirm your modem’s operation.
•Ensure your IP address is set up correctly.

No network connection

•If using a wired network connection, check to ensure the LAN
cables are connected properly (- p. 21).
•Ensure the modem and router power cords are plugged in
and the devices are operating properly.
•Ensure your IP address is set up correctly. See Section
(- “Setting up the Network”).
•Check to ensure proper operation of other network connected
devices.

Network Setup fails (Auto)

•Check to ensure the LAN cables are connected properly
(- p. 21).
•DHCP is not enabled on the router, or no router is present.
Refer to your router’s documentation for instructions on
enabling DHCP. If your router does not support DHCP, you
must manually set up the IP address.
•Internet service is not available. Check your cable/DSL
modem or contact your ISP for Internet service issues.

Network Setup fails (Manual)

•Ensure the TV IP address is not the same as any other device
on the network.
Example: IP address 192.168.0.100 and IP address
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 the IP address
192.168.0.100 with the Subnet mask 255.255.255.0, the TV
has the IP address 192.168.0.101 with the Subnet mask
255.255.255.0; 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.

Unstable network connection

•When using a wired home-network connection, unplug the
LAN cables, and then reconnect them.
•When using a wireless home-network connection:
– Remove AC power from the router and the television for
1 minute.
•Reconnect AC power to the router.
•Reconnect AC power to the television and turn it
ON. After 2 minutes, check connection stability.
–Connect with LAN cables, if possible, and check
connection stability.
– Repeat the wireless network setup procedure and check
connection stability.

The DMS name is not displayed

•The LAN cables, if used, are not connected properly
(- p. 21).
•The WLAN, if used, is not configured properly.
•The network setup on the Server is incorrect. Make sure both
the DMS and TV are using the same network type (DHCP/
manual) and have compatible network settings.
•Too many DMSs are connected. You cannot connect more
than 32 sharing devices at one time.
•The DMS is not turned ON.
•The “server” is not a DMS device.
•Check the firewall and streaming settings on the DMS.
