On your laptop (which needs to be connected to the wireless router in question, wither wirelessly or wired) go to- start-run and type in cmd
In the black box type in ipconfig
Make a note of your default gateway. (probably 192.168.0.1 or something?)
Type that address into Internet Explorer
You should be prompted for login, which in my experience with Belkin is either both blank, admin admin, or admin for u/n and no password......
When you get past this screen, report back what options you have, or tell me the exact router and i will be able to talk you through it
