Hi, Don't know how other broadband connections in India work, but Sify certainly isn't what you'd expect a "broadband" connection to be like.1) You don't need a modem for using Sify. You need a LAN card only.2) Yes, you get egt a Userid and Pasword on Sify when you sign up with them.3) Yes, you have to login most of the times when you want to use Sify because Sify automatically logs you out after several hours if you forgot to logout yourself. This is apart from a bug on Sify which logs out subscribers every 15-20 minutes, which new subscribers to Sify face but it can be sorted out fairly simply now.All said, if you want a satisfying broadband experience in India, Sify in my opinion isn't the one to go for. It's too frustrating an experience most of us have on Sify.
