Manuals for Toshiba televisions are available on the Toshiba Support website (http://support.toshiba.com/download
). Below is the link for the Toshiba LCD TV 40G300U1.http://cdgenp01.csd.toshiba.com/con...
Please refer to pp. 21: "Connecting a home network":
"The LAN port allows your Toshiba TV to connect to your home network. You can use this revolutionary home entertainment networking system to access photo, video and audio files that are stored on a DLNA server and play/display them on your TV. For supported formats, see page 53.
•• The TV’s home network connection allows access to file sharing only. You will NOT be
able to use the TV to access the Internet."
If you have a laptop with wireless capabilities and an HDMI port, you can use it to tap into your wireless router and access the Internet, then output the signal to your TV.
