Troubleshooting Wi-Fi Network Problems
Checkpoints
yMake sure that you have the latest version of the software.
-If you are using a Wi-Fi router, check whether you have the latest firmware installed.
-If there are any available updates, update the firmware according to the manufacturer's instructions.
-/ (Home) (Settings) (Advanced) General About This TV Software Version
Check the current software version and if there is an available update, install it.
yCheck if the same symptom occurs with two or more Wi-Fi devices.
-Wi-Fi problems may be related to network condition and a device that is connected to the network.
-If other Wi-Fi devices can connect to the Internet at the same location as the TV, then your Wi-Fi router is
probably normal.
yCheck the power and Ethernet cables of the Wi-Fi router.
-When the Ethernet cable connected to the Wi-Fi router is loose or disconnected, network problems can
occur.
-Check all power and Ethernet cables of the Wi-Fi router to see if they are correctly connected.
yCheck the Wi-Fi router to see if the router is set to the recommended wireless settings. If network problems
continue, reset your network devices.
yCheck the signal strength of the Wi-Fi router to connect to from the TV UI.
-The that is next to the Wi-Fi router name (SSID) in the menu indicates the sensitivity of the receiver.
-It is recommended that you connect to a Wi-Fi network with 3 or more bars of signal strength.
-If the bars of signal strength are less than 3, the network connection status may be weak or unstable, so
shorten the distance between the Wi-Fi router and the TV.
yIf the signal strength of the Wi-Fi router is weak, wireless speed slowdowns and network disconnection may
occur.
yTo supplement wireless coverage of network equipment, your Wi-Fi router should be placed in the middle of
the network equipment.

yInterference Factors
If there is any interference from surrounding equipment, the network connection may be weak or unstable.
-Wireless telephones that operate in the 2.4 GHz or 5 GHz bandwidth
-Wireless speakers that operate in the 2.4 GHz or 5 GHz bandwidth
-Video transmitters that operate in the 2.4 GHz or 5 GHz bandwidth
-Other wireless devices (Microwaves, cameras, baby monitors, neighboring wireless devices, etc.) that operate
in the 2.4 GHz or 5 GHz bandwidth.
yHow to reduce the effects of interference between Wi-Fi and Bluetooth devices
-Set the channels on your wireless network equipment to avoid the 2.4 GHz or 5 GHz bandwidth which has
lots of interference.
-If possible, use the 5 GHz wireless network.
-If the Wi-Fi router is located too far away or in environments with high interference, the network connection
may be weak or unstable.
-In this case, move the Wi-Fi router closer to the TV or check if there are any obstructions (e.g., concrete walls,
cabinets) between the two devices.
