Airport Extreme won't recognize IP address

[kgrass]

My Airport Extreme isn't recognizing the IP address from my cable modem. When the modem is connected directly to my MBP the internet works fine. When connected to the router I don't get any internet. I have powered off the modem and router and all devices, brought up the modem first (waited for all lights to come on), powered up the router, then the devices. Still nothing. I've tried deleting the DNS server information and resetting - nothing seems to work. There is a green light on the ethernet port on the Time Capsule so I believe the port is fine.

Any ideas are greatly appreciated.

AirPort Extreme using self-assigned IP

OK, after a very long time I finally have gotten this resolved. Here is a link to the Apple Support discussion detailing what worked: http://discussions.apple.com/message.jspa?messageID=12177236
