You can change your network connections from Ethernet cable to Wi-Fi and vice versa.
- Press MENU on your remote.
- Go to Settings -> General -> Network and Connection
- Select the Wi-Fi network you wish to connect to and enter the password using the remote control.
- Select JOIN.
If you cannot see the Wireless/Wi-Fi connection, select Rescan networks.
Also, make sure the router is close enough to my device.
