Try the following ...
AirPort Extreme Base Station Setup (AEBSn) w/Cable Modem
Perform a "hard" reset of the AEBSn.
o (ref: http://docs.info.apple.com/article.html?artnum=107451)
Modem/Router Power ReCycling
o Power-off the Cable modem, AEBSn, & computer(s); Wait at least 30 minutes.
o Power-on the Cable modem; Wait at least 15 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
Setup the AEBSn
Either connect to the AEBSn's wireless network or, temporarily, connect your computer directly (using an Ethernet cable) to one of the LAN ports of the AEBSn, and then, using the AirPort Utility in Manual Mode, check these settings:

Once you have verified Internet access, I strongly suggest that you use wireless encryption (WPA or WPA2) to secure your network.
A router will have at least two IP addresses, one for the WAN-side (Internet facing), and one for the LAN-side (your local network).
The WAN-side address is typically provided by your ISP and is an address that can be "seen" from the Internet. You can find this WAN-side IP address on the AirPort Summary page within the AirPort Utility.
On the other hand, the default LAN-side IP address of the AirPorts is 10.0.1.1. This LAN-side address is the one "seen" by computers connected to the AirPort (both via wire or wirelessly).
A big "thank you" to Tesserax.
I just installed Comcast cable, and had bought a new AEBS to set up my wireless. I spent about 24 hours getting very, very frustrated - both with my apparent inability to get it working, and with the lack of service from Comcast.
I've set up numerous Airport configs, and thought it would be piece o' cake. It wasn't. The airport wireless came up nice and strong, but I was unable to get a connection to the internet via the wireless, even though I could via a hard-wired ethernet cable.
I followed the protocol Tesserax gave - and BINGO, I'm now happily online wirelessly. Two things seemed to be different to my protocol:
1. How long I let the CATV modem stay unplugged. The old 5 minute rule seems not to apply - but the 30 mins works.
2. Setting up first w/o security; then going back and setting up WPA/WPA2. I don't know why - but this seems to make a big diff.
thanks Tesserax. All Comcast / Mac / Airport users should get a copy of your setup protocol.
