Network will not assign IP address to XBOX

My home wireless network allows my Xbox to sign in using the WPA2 passphrase, but it does not assign an IP address.  I have check that DHCP is turned on, that MAC filtering is off, tried the wired ethernet connection, and basically went through the entire trouble shooting thing built into the xbox.  I'm begining to think the xbox is defective. 

I have answered the recommended questions below to help facilitate an answer:

What Country/State/Province do you live in?
USA, Ohio

Modem brand & model number:
2Wire

Router brand & model number:
Netgear WNDR3400

Network Connection Type: Wireless/Wired
preferably wireless, but i tried both

If Wireless, what type of encryption are you using?
WPA2 but i also tried without encryption.  same result.

Things you have tried:
Is UPnP Enabled? Yes/no/Unknown
Yes

Is NAT Type Open?
I don't know what this is and cannot find a NAT type setting in my router.

Any Error Codes you encounter:
What type of internet do you have? Cable/DSL/T1/3G?
DSL


Who is your ISP(Internet Service Provider)?
AT&T RoadRunner

When you run "Test Xbox LIVE connection" what is the exact message shown on screen?
Can't obtain an IP address from your router or modem.  Turn your router or modem off and back on, then wait 30 seconds.  (I did this several times)

Try running the "Restore to factory defaults" function on your Xbox.  It is in the Network settings under Additional Settings. Then try connecting it to your router again.

I've tried assigning a static IP address as the trouble shooting guide suggested. This had no effect.  I have three other computers on this network and the router assigns them IP addresses just fine.  I think the router is doing what it's supposed to.

Your issue may come from the setup your using.  Putting another router behind a 2wire router does not work very well.  2wire devices are both modems and routers, in one device.  So you typically do not need another router, like a Netgear, behind it.   Although  this should not prevent you from getting an IP address, it will affect your connection to Xbox Live. If you want to use a Netgear router behind the 2Wire, you should put the 2Wire in "bridge" mode. That would make it act more like a standard modem.

Log into your routers admin page and assign it a static ip address. Usually when a network wont assign a particular device an ip address it's not usually the device but it's the router.

You should power cycle your modem and router before setting the ip address
