If you select the Pure High-throughput (Greenfield) 802.11n mode and the
Encryption type is set to WEP, TKIP or TKIP AES (WPS2Mixed) on your AP or
wireless router, Samsung TVs will not support a connection in compliance with
new Wi-Fi certification specifications.
If your wireless router supports WPS (Wi-Fi Protected Setup), you can
connect to the network via PBC (Push Button Configuration) or PIN (Personal
Identification Number). WPS will automatically configure the SSID and WPA key
in either mode.
If your router, modem, or device is not certified, it may not connect to the TV
via the "Samsung Wireless LAN adapter."
