I have a bsnl bband modem with wifi ( ZXDSL 531BIIV7.3.of_D09_IN)
1. I want to change the dsl router username/password given as 'admin'.
2. My Wi-Fi is secured with a password. I want to set password for use of bband on my pc as well. Since activation of Wi-Fi the net for my pc gets connected by default when modem is put on without any password protection.
