Hi and welcome to
D-A-L
where did you get the router from?
Have you connected the moden to the router through the WAN port, have you got a spare ethernet cable to connect the laptop to the router with wires, to make sure the router's working properly.
start >>
Run >>
CMD >> type ipconfig
(hit enter) that should give you an IP Address, a subnet mask and a default gateway, the default gateway is the IP address of the router
if you type that into your address bar of your homepage you should be able to get to the home page of the router
