I too have the same set up as you, apart from the fact that my initial configuration was completed via a pc connected directly to the cable modem. Repeat the initial configuration you carried out by directly connecting to the modem via the laptop to ensure that everything works (ie you can get onto the net)
Once this is working, turn off the modem and connect the Ethernet cable from the modem to the WAN port on the router. Restart your modem and manually check the settings are as follows by logging into the router wirelessly.
1.WAN settings - dynamic IP address
2.Press 'Clone MAC address' - this will effectively be the address of the device you are using to conect to the router (wireless card, etc) and then on to the modem.
3. DHCP server set to enabled
4.Static DHCP disabled
5. Save the settings on the router which will effectively restart it and le voila - were cooking on gas

This should enable direct connection to the internet. Any problems let me know
