How to change BSNL router password?

 IMPORTANT: Change your router password as soon as you login for the first time itself.Otherwise, attackers can easily access your networks. For eg: someone else can change your WiFi settings so that it can be accessed by public.

For changing , first of all go to 192.168.1.1 in your web browser(like Internet Explorer, Firefox, Google Chrome etc) and give default username and password both as "admin". Go to "Management"->"Access control"->"passwords". Select user as "admin" and type your old and new password and then "save&reboot". Done!

How to change DNS server addresses of your router ?

Login to 192.168.1.1 . Then go to "Advanced setup" ->"DNS"->"DNS Server". If you want to add DNS server other than that used by BSNL, untick " Enable Automatic Assigned DNS" and add your primary and secondary DNS server address. You can use OpenDNS server addresses ie 208.67.222.222 and 208.67.220.220.(Why?)
