Troubleshooting Wi-Fi Network Problems

Software Version
Check the current software version and if there is an available update, install it.
• Check 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.
• Check 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.
• Check the Wi-Fi router to see if the router is set to the recommended wireless settings. If network problems
continue, reset your network devices.
• Check the signal strength of the Wi-Fi router to connect to from the TV Ul.
- The
'9'
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.
• If the signal strength of the Wi-Fi router is weak, wireless speed slowdowns and network disconnection may
occur.
• To supplement wireless coverage of network equipment, your Wi-Fi router should be placed in the middle of
the network equipment.

• Interference 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.
• How 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.
