Sometimes video streaming quality is poor when using the wireless LAN.

• The wireless network connection quality varies depending on the distance or obstacles (e.g. wall) between the TV/USB Wireless LAN Adapter and the wireless router (access point), environment interference, and quality of the wireless router (access point). If using USB Wireless LAN Adapter, it is suggested to use a wireless router (access point) supporting 5GHz operation for video streaming and place it closer to the USB Wireless LAN Adapter (not applicable for models with built-in wireless LAN device).

• Built-in wireless LAN TV uses the same 2.4GHz bandwidth as Bluetooth devices, therefore there may be rare occasions when communication speed by Wi-Fi may deteriorate if Bluetooth applications (e.g. mouse/3D Glasses, etc.) are used at the same time. In this case, use a wired connection for the Internet, or connect with a USB Wireless LAN Adapter at 5GHz.

Wireless LAN connection fails or radio reception conditions are poor.

• Check the installation location of the TV and wireless router (access point). Signal condition may be affected for the following reasons.
• - Other wireless devices, microwaves, fluorescent lights, etc., are placed nearby.
• - There are floors or walls between the wireless router (access point) and TV.
  If the problem persists even after checking the above, try making a wired LAN connection.
• When using a USB Wireless LAN Adapter, move it to avoid signal interference by using an extension cable with base unit (optional accessory).

The TV cannot connect with your wireless router (or access point) at 5GHz.

• Use the optional USB Wireless LAN Adapter to connect with your wireless router (or access point) at 5GHz. Then, set [Wi-Fi Direct] to [Off]. Press the HOME button, then select [Settings] → [Network] → [Wi-Fi Direct] → [Off].
