I bought a new modem today (ATT 2wire wireless router with modem). I am trying to install my airport extreme, but keep getting the dreaded flashing amber light and an error message telling me that the airport is not connected to the internet. I called apple and they suggested that the airport is not reading the IP address of the router/modem. Can anyone help? I've searched the internet for guidance to fix this problem, but haven't found anything. Thank you in advance for any help.
