I used ADL broadband for over a year and I didn’t like it at all.
Even though the service and support was good, the connection used to get disconnected every now and then. At last I threw away their modem and switched to BSNL (I am very much satisfied with BSNL).
The only advantage with Asianet is that broadband rates are very cheap. If you can pay a little more then you must not go for ADL. They think that India is a third world country and people dont care about quality of ISPs. I don’t even want to think about how much I suffered because of this low quality ISP.
Anyway, I don’t know how good this ISP is now. Sometimes they might have improved. God knows.
