Just a bit of info....Belkin routers use this address. If you type it into your url field and then press enter you should get your router's login page. Default name and password is usually admin and admin but you should have been requested to choose a name and/or password when you installed it. You did store it somewhere, didn't you?
Linksys routers use 192.168.1.1 as do many others.
Should have mentioned, you may need to have administrator privileges set up on your account. Easy to do: Start>settings>control panel>user accounts and investigate.
