|From what I can see, you've got the setup correct so far:|

One question about the following line:
Disconnected the internet cable from the Motorola modem and...
The internet cable will have to go to the "external" port on the new combo unit (combination modem/router/AP). Did you plug it in there?
If not, that's why you have no internet.
If you have the internet cable connected correctly you need to check the configuration of both routers. Chances are you have them both using separate subnets. If that's the case, change the wireless N to the same subnet and it should work.
Do click on my name above and read my "how-to" guide on connecting a second router. You'll want to pay attention to the "LAN port to LAN port" scenario.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
