Try this:

To configure your router manually:

Reset the router - Hold the reset button of the router for 30 seconds then Unplug it for 10 seconds then turn it back On.

Just follow these simple steps:

Open a browswer window and type http://192.168.1.1 into the address bar and click on Go.

The log-in window will appear.

Skip user name and type admin (admin is the default password) as the password, and click OK.

I would just press the reset button, usually inset and requiring a pencil or paper clip. You'll lose all of your settings, but at least then the default login should work. Of course, the problem might be with the web page itself that you're trying to access. Maybe try to access a different page directly from the Start, Run line by typing in the address manually. If you have more than one browser program, try those, too.
