It almost seems to me that your router is set to use DHCP and you Laptop isn't, or visa-versa. Make sure that on your router DHCP is enabled, and then go to start>>Control Panel>>Network Connections. Find the connection that uses your wireless NIC. Right click>>Properties>>General Tab>>Click on the text="Internet Protocol (TCP/IP)>>Properties. Make sure that "Obtain an IP address automatically is selected. Select Ok>>Ok and try it now.
Also double check again to make sure you arent doin any mac address filtering..
