Airport Extreme not working with new modem I have an Airport Extreme that was previously connected to a, well lets say not great modem. So I replaced the modem with 'Nucleus Connect', which is Fibre I think. (I live in Singapore and they installed this here). And I have a problem, my airport extreme just does not work anymore! I plug it into the modem and power source, but it flashes amber. Here is what I have done:


Factory default reset
Power down computers
Power down airport extreme
Power down modem


So what now!? In my Airport Utility here are the problems:


No DNS Servers
No Internet Connection


Also, the router shows up sporadically in Airport Utility and when it does,  it shows up but with a warning sign and my only option is to forget it.

Can someone point me to troubleshooting steps to resolve this issue?
The Amber light could mean many things.  

Steps I would take:

Install new firmware http://support.apple.com/kb/DL1481?viewlocale=en_US&amp;locale=en_US

Second: 

Factory default reset

Does your modem have a router built into it?  If so, you need to put that either into bridge mode or router behind router mode.
