Routers are best administered through a wired connection. Wireless admin is not the best method.

Try
clicking Start -> choose run
enter cmd
Black box opens - type ipconfig /all

this will provide connection info similar to:

The line in bold is the router address, this is what you need to put in the address bar in internet explorer, it will provide an authentification box to log into the router.
I have removed numbers from the above but specifically you need the gateway address to access your router.
If you use wireless and any of the security info is incorrect (eg SSID, encryption) you may be able to 'see it' but you will not be able to connect to it, therefore using the cable to connect directly is the most reliable method. Failing all this there should be a way to reset the modem to it's default status.

As for the laptop what are you using for the wireless connection ?
Built in transmitter or a plug in PCMCIA card.
I take it we are all assuming DHCP is used...
