First I used BSNL broadband connection before 2 years but I had some problems like disconnection of network from 6pm to 11pm. So, I just disconnected it and gave a Reliance broad band connection it was good until I had problem in its cable. And it was the worst experience that I had with internet connection you will get no response from your customer care and even though your problem gets solved it is good for only few weeks.
So I planned to give a wireless connection then my friend recommended to go for tikona and also I found the tikonas wireless dish is on my neighbors house so I gave Tikona internet connection.
So far its the best internet connection that I had i.e it is better than BSNL and Reliance.
So, I recommend you to give Tikona connection only if you have the Tikonas Dish near your home.
