Why is my Airport Extreme blinking yellow?

I just had my Internet upgraded to 150MBps. It is working fine. The provider came in and changed the modem. Ookla Speed test shows the increase in speed, but light on the router is still blinking yellow. Airport utility shows a red number 1 and an orange dot. When I edit the router it shows an orange dot and "Double NAT."

Open AirPort Utility

Click on the picture of the AirPort Extreme

Click Edit in the smaller window that appears

Click the Network tab at the top of the next window

Change the setting for Router Mode from DHCP and NAT to "Off (Bridge Mode)"

Click Update at the lower right of the window and give the AirPort a minute to restart





Your provider supplied you with a modem/router, also known as a gateway. The Double NAT error appeared on the AirPort to tell you that there were two devices both trying to act as routers on your network, when you only want one device acting as a router on the network.


A guess would be that your "old" modem was just that......a modem.....and not a modem/router or gateway. If this were the case, the DHCP and NAT setting would have been correct for your AirPort Extreme.


The AirPort Extreme will continue to provide WiFi service for your network.
