There may be two reasons for this situation:
One is the browser problem I change the browser or the following to clear the cache, the other is the password modified is not the original admin password we may restore factory settings.
Solution One
1. To solve the browser problem first we open it, then click "Tools" on the menu and click "Internet Options" in the dropdown below.
2. Furthermore, we click on "Internet Options"--click "General"--"Delete"--"Delete browsing History"-"OK" on it.
Solution Two,
The password has been modified. We only need to reset the router to login.
Reset method:
The Wps/rst button is the Reset key. Under power state, press the Wps/rst key for 5-10 seconds, the SYS led flashes fast 3 times or is released
Wps/rst key, the SYS light is again shiny that reset succeeded.
All right, after the reset, we just restart the router, then re-enter the address bar and then enter the admin username and admin password in the pop-up interface to log in, and then modify the password and then modify the ADSL Internet settings 192.168.0.1.
