just hardwired a computer to the router and open a web browser. on the address bar of the web browser type http://192.168.2.1 (default ip address of the router) and you will be prompted with the login screen. by default you don't need to type anything on the password field. now you will prompted with the router's page and from there you can set it up.
click here for the manual.

hope this'll help you

Are you trying to configure the router wirelessly. Connect your computer to the router with a lan cable and then access the router and change its wireless settings. since you cannot change the wireless settings wirelessly as you will get disconnected.

SOURCE: How do I make my SMC Barricade router go to a startpage

It sounds like what you want to do is have your web browser display a page when you open it... this is called setting your home page...

If you use MS Internet Explorer then
1) Go to the tools menu
2) Go to internet options
3) at the top set your home page
4) Press apply and ok
5) Now press the home button - this is the page Internet Explorer will display whenever you open it

IF this helped you then please help me and vote kindly.
