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 and the wireless router (access point), environmental interference, and the quality of the wireless router (access point). In this case, use a wired connection for the Internet, or try the 5GHz band.

• The 5GHz band may not be supported depending on your region/country. If the 5GHz band is not supported, the TV can only connect to a wireless router (access point) using the 2.4GHz band.

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.

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