Check the current software version and if there is an available update, installtt.
• Check if the same symptom occurs with two or more Wi-F1 dev1ces
- Wi-Fi problems may be related to network cond1tion and a dev1ce that is connected to the network.
- If other W1-Fi devices can connect to the Internet at the same location as the TV, then your Wi- Fi router 1s
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 ts set to the recommended wireless settings. If network problems
continue, reset your network devices.

that ts next to the Wi-Ft router name (SSID)
tn
the menu tndicates the sensitivity of the receiver.
- It
IS
recommended that you connect to a Wi-F1 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.

IS
weak, wireless speed slowdowns and network d1sconnection may

- Wireless telephones that operate in the 2.4 GHz or 5 GHz bandwidth
- Wireless speakers that operate
tn
the 2.4 GHz or 5 GHz bandw1dth
- Video transmitters that operate in the 2.4 GHz or 5 GHz bandwidth
- Other wireless devices (Microwaves, cameras, baby monitors, netghboring w1reless dev1ces, etc.) that operate
tn
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 w1reless network equ1pment to avo1d 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 w1th h1gh rnterference, the network connection
may be weak or unstable.
- In this case, move the Wi-Fi router closer to the TV or check tf there are any obstructions (e.g., concrete walls,
cabinets) between the two devtces
