How do I connect the TV to a wireless Wi-Fi network?
Navigate to Quick settings > TV options > Settings > Network & internet > Wi-Fi to turn Wi-Fi on, then select your wireless network from the list of found networks and follow the on-screen instructions. If your network name is hidden, select 'Add new network' to enter the network name manually. A message will be shown when the connection is successful.
