Redirection problem while taking any site (solution works for me)

I have a problem with redirection,while taking any site fron my android phone browser or chrome browser on my pc a popup jumps up and asked to download an app or something.I am very much irritated with this problem and finally found a way to get rid of this problem

I am sharing the solution that works for me,please comment if its work for you.


Step-1

The problem is mainly from the modem,you need to type an address to get the setting of the modem from your browser.
Generally it will be 
http://192.168.1.1
may be you all have set with the default user name and password.
username:admin
password:admin


Step-2

In the setting there will be option to set the DNS or menu name like DNS SETUP,if you find you will able to see some numbers like 8.8.8.8,80.126.84.32 like that you need to clear it and set it to automatic mode and save(apply setting).

Step-3
This problem may come again,if you not changed you default user & password,so got to chage password option of you modem setting and change the password at once.


Step-4
Restart you modem and clear you browsing data and cookies from your browser and enjoy a problem free browsing.

I think this helps you.................
