Is this TV capable of WPA2 or only WEP
Asked by: Anonymous
The LG UHD 73 Series 75 inch Class 4K Smart UHD TV with AI ThinQ® (74.5'' Diag), Model # 75UN7370AUH uses the Wi-Fi® Protected Setup (WPS) feature (WPS PBC (Push-button configuration) or WPS PIN) which is a built-in feature of many routers that makes it easier to connect Wi-Fi enabled devices to a secure wireless network. If your wireless router supports WPS (Wi-Fi Protected Setup), you can easily connect to the wireless router by pressing the WPS-PBC button on the router. Press the wireless router’s WPS-PBC button and then press the TV’s [Connect] button. You can also connect via WPS PIN. This is a method to connect to an access point using a Wi-Fi Protected Setup-Personal Identification Number (WPS-PIN). Select the access point (AP) to which you would like to connect. Enter the PIN displayed on the access point’s Wi-Fi device. WPS automatically configures the SSID and WPA key settings. The TV only supports the following wireless network security protocols:
• Authentication Modes: WEP, WPAPSK, WPA2PSK
• Encryption Types: WEP, TKIP, AES
On the TV, press Settings on the remote control, then on the TV, press Advanced Settings > Network > WiFi Connection > Connect via WPS PIN. If the pin code option is grayed out, connect the TV to the wireless network first, then the WPS option/Advanced Wireless option will become an available option...^IFV

I love the picture on this model. I know this model is not equipped with the TruMotion feature, but is there something similar that can be employed? I have noticed on certain cable channels (TBS in this case) a problem with smoothing.
