How to Access Router Without knowing Username & Password

In some cases we want to change settings of our router but suddenly we realized that we don’t know the username and password of router.SO here is the solution for it

STEPS:

1) Open cmd and type in "ipconfig"

2) Goto you browser and type in the Default Gateway in the address bar. e.g 192.168.1.1

3) Now you have to go to your modem (physically) and on bottom 
of the modem their will be Modem Access Lode

4) In Username type in "admin" or "user" and in password type that MODEM ACCESS CODE.

5) If there is not the Modem Access Lode Code than you can try typing in the default USERNAME and PASSWORD.The default username is "admin" and default password is also "admin"

7) If default username and password also didnt work then we have another solution! You can bypass the USERNAME and PASSWORD page!!! What you want to do is just type you'r default gateway in you'r browsers address bar and type in "/main.html" and here you are! Congrats..You are in you'r router's setting!
    e.g "192.168.1.1/main.html"

8) ENJOY....
