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?

Have you plugged your computer directly into the modem with ethernet to make sure the modem is connected to the internet? Are you sure the ethernet cable you're using to connect the AirPort to the modem is good and plugged into the WAN port on the Airport? – Richard Oct 13 '12 at 10:45
My modem is indeed connected to the internet, today I got the installation guys offered me a new router after I asked this question and it works. But I love my airport extreme! And I want it working with this modem! I will try the WAN port thing and get back to you – MCKapur Oct 13 '12 at 11:10
So you can connect your computer directly to the modem and get online, yes? The "WAN port thing" is the only way to plug a router into a modem like yours: Airport Extreme routers have 1 WAN port and 3 LAN ports for taking ethernet out. Sometimes in haste people plug the modem into one of the LAN ports. Just checking the hardware... – Richard Oct 13 '12 at 12:54
@Richard I am pretty sure it is in the WAN port, the one which has a gray circle indicator – MCKapur Oct 13 '12 at 13:12
That sounds right. And are you sure your computer can get online when connected directly to the modem with Ethernet? – Richard Oct 13 '12 at 19:46

The Amber light could mean many things.

Steps I would take:

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