I hate to say that Newdelhi is not that cyber friendly and you wont find many hotspots or wifi locations in Delhi which realy sucks. I read it on some website that there is Wifi at the airport but last time I was at the airport there was no networks showing up at anycorner of the airport and when I asked the information and help desk guy he had no clue what I am talking about, he probbably didnt know what wifi means so at last I just gave up on it.
There are a few cafe's advertised as being wifi enabled but ive never been to anyof those so dont really know if the really have it or its just a gimmick to get a few more customers.

If you know of any hotspots in Newdelhi that actually work please add those locations here so every one can know about them. I really wish I was in Bangalore.
