Normally password is password as few people mentioned above. Since i had a tough time after changing the password, i couldnt use it. what would have happened was, your password might have got locked by trying all the different combination. Normally they sent a mail to the bsnl.in mail id with all the information (16 digit username/password to login to see usage statistics, and email-id/password, router-modem username/password (pppoe) !! Why they made you to dial from computer as it can be stored in router/modem itself ? Shout at them... Scream at them.. All the best arun !
