Can anyone tell me how does BSNL provide the authentication for username and password? My issue is: I already have a Bsnl connection and in workin state.. My problem is when is use my username and password, i get an ip on the status screen and have a connection for internet, but when i use username and password of some one else, i dont get a connection status, nor do i get an IP. I wanna know, if BSNL authenticates with username and password only then i should be able to use others usernam and password as well (working usernam & password). So can any one answer my question!!!
