Network Setup
Setting up the Internet 
connection
Using the network feature you can connect the 
TV to the Internet. The set-up procedure differs 
depending on the type of network and LAN 
router. Before setting up the Internet connection, 
be sure to set up a LAN router. Check your 
wireless LAN environment using the following 
chart.
Wireless LAN
Wired LAN
 , Type 4
* Type 1 is easier to set up if your router has an 
automatic setting button, e.g. Air Station One-Touch 
Secure System (AOSS). Most of the latest routers 
have this function. Check your router.
Type 1: Follow the configuration for “Secured 
Network with Wi-Fi Protected Set-up (WPS)”.
Type 2: Follow the configuration for “Secured 
Network without Wi-Fi Protected Set-up 
(WPS)”.
Type 3: Follow the configuration for 
“Unsecured Network with Any Type of Wireless 
LAN Router”.
Type 4: Follow the configuration for “Wired 
network set-up”.
Type 1: Secured network with 
Wi-Fi protected Set-up (WPS)
The WPS standard makes security of a wireless 
home network as straightforward as pressing the 
WPS button on the wireless LAN router. Before 
setting up a wireless LAN, check the location of 
the WPS button on the router and verify how to 
use it.For security purpose, “WPS (PIN)” provides a 
PIN code for your router. PIN code is renewed 
every time you select “WPS (PIN)”.
1Press HOME, then select   > 
“Network” > “Network Set-up”.
2Select “Wireless Set-up”.
3Select “WPS (Push Button)” for Push 
Button method or “WPS (PIN)” for PIN 
method.
~
Button name of the WPS may differ depending 
on the router (e.g. AOSS button).
4Follow the instructions on the set-up 
screen.
Type 2: Secured network without 
Wi-Fi protected Set-up (WPS)
To set up a wireless LAN, SSID (wireless 
network name) and security key (WEP or WPA 
key) will be required. If you do not know them, 
consult the instruction manual of your router.
1Press HOME, then select   > 
“Network” > “Network Set-up”.
2Select “Wireless Set-up”.
3Select “Scan”, then select a network 
from the list of scanned wireless 
networks.
4Follow the instructions on the set-up 
screen.
~
If you use WPS for network set-up, the security 
settings of the wireless LAN router activate, and any 
equipment previously connected to the wireless 
LAN in a non-secure status will be disconnected 
from the network.
In this case, activate the security settings of the 
disconnected equipment and then reconnect. Or, you 
can deactivate the security settings of the wireless 
LAN router, and then connect the equipment to a 
TV in a non-secure status.
