There's no in-built Wireless LAN. The model is  LTDN40D36T (customized for our regional market). It has a 2 year warranty.

In TV electronics parlance, a set with LAN capability will have the label 'SMART' while one with an in-built digital TV tuner will be labelled 'DIGITAL'.

PS : When checking out the reviews online, you will be better off sticking to local/regional write-ups. The same model will have different features in different markets.
