Q: Airport Extreme green light but no valid IP Address

I have a satellite based internet service. I have a brand new Airport Extreme that pushes out a working wireless network (though I do get a Double Nat notice). Yeah! This AE used Bridge Mode and uses DHCP.

 

I have a 5th generation Airport Extreme elsewhere that is hooked up to a working Ethernet connection. I tested the Ethernet cable on my Mac that was going to the WAN port and I can get online. Though the AE has a green light in front when I hook-up a Ethernet cable from a LAN port I can't get a valid IP Address nor can I get online. To get the green light on front I have it using a static IP Address (it is the same range as the brand new AE) and its in Bridge Mode.

 

Any suggestions to get the 5th generation AE working wirelessly and wired is appreciated.

 

Thank you for looking.

    Does your satellite Internet ISP provide you with a modem or similar device that you connect the AirPort Extreme by Ethernet to? A Double NAT condition would indicate that there is another NAT router upstream of the Extreme. This is not typically a condition you want your network to be in especially for data throughput performance with satellite Internet's limited speeds.

    I have a 5th generation Airport Extreme elsewhere that is hooked up to a working Ethernet connection.

    ... and would that Ethernet connection lead back to the new Extreme?

    I tested the Ethernet cable on my Mac that was going to the WAN port and I can get online.

    Just to be sure I understand your statement. Do you mean that you tested the Ethernet cable coming from the new Extreme that you would plug into the WAN port of the 5th gen Extreme worked for Internet access when that cable was plugged into your Mac?

    Though the AE has a green light in front when I hook-up a Ethernet cable from a LAN port I can't get a valid IP Address nor can I get online.

    ... but the Mac could? A green status LED just means that the base station did not find anything amiss with it current configuration. It does NOT mean that you have network or Internet connectivity. Actually I am surprised that you didn't have a flashing amber light instead and that you were told that the base station could not get a valid IP address.
