Troubleshooting Wi-Fi Network Problems
Checkpoints
Make sure that you have the latest version of the software.
y
- 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.
- 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.
y
- 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.
y
- 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
y
continue, reset your network devices.
Check the signal strength of the Wi-Fi router to connect to from the TV UI.
y
- 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 number of bars indicating 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
y
occur.
To supplement wireless coverage of network equipment, your Wi-Fi router should be placed in the middle of
y
the network equipment.
Interference Factors
y
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
y
- Set the channel 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.
