In a network test over a wired
connection, the second items
which include the IP address,
subnet, gateway and DNS server
fail.
If the IP address, subnet mask and gateway address were typed in manually, check that
•
valid values were entered. (For example, 0.0.0.0 is not valid for an IP address, subnet
mask or gateway address.) If the IP address the user entered in is invalid, change it to a
valid IP address.
In a network test over a wired

by selecting [Wireless Network Setup] and [Select Network].
If there is a sharing device with the same SSID, try to connect to this device.
If the IP address is set to automatic and you cannot connect to the sharing device using
3.
option 1 or 2, check the settings of the sharing device to see if the DHCP server function on
the sharing device is enabled. If disabled, activate the function. (For details on how to set up
the sharing device, see the manual for the corresponding sharing device.)
If you still cannot connect to the sharing device after confirming options 1, 2 and 3, reset the
4.
sharing device and try again.
There could be several causes of the connection failure. Check the AP settings to see if the
5.
following condition is found:
The Pure high-Throughput 802.11n mode (or Greenfield 802.11n mode) is selected -
and the Encryption type is set to WEP, TKIP or TKIP-AES.
Under the conditions stated above, Samsung TVs will not support a connection in -
compliance with new Wi-Fi certification specifications. This is intended to maximize
the performance of the AP, TV and TV network.
To connect to the AP, set the Encryption type to AES. If Pure High-Throughput
-
802.11n mode (or Greenfield 802.11n mode) is selected and the Encryption type
is set to AES, your Samsung TV will connect to the AP providing you with optimum
performance.
