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).
Wireless LAN connection fails
• 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.
