When using Wi-Fi, make sure the Wi-Fi password is entered correctly.
Turn off the access point. Wait for 2 minutes and then turn them back on.
Ensure that there are no obstacles between the TV and the access point. (The Wi-Fi strength can be decreased by
appliances, cordless phones, stone walls/fireplaces, etc.) Reduce interference by not using or turning off other wireless
devices.
If the Wi-Fi connection fails, connect the TV to the access point via a LAN cable. If the TV can connect via the wired
connection, there might be a problem with the Wi-Fi access point. In this case, try using a different access point.
When using a LAN cable, use one rated CAT 5 or higher. Make sure it is plugged in at both ends.
When using a static IP, ensure network addresses are entered correctly.
If the problem persists, contact your Internet Service Provider or modem manufacturer.
