My DSL provider, who placed at home a modem with 4 ethernet ports, does not have DHCP and gave me the following details: IP, Subnet Mask, Gateway (Im presuming this is the Router address to be entered in Airport Utility), DNS and alternate DNS. I configured it as Static IP, and initially AirPort Express suggested that I put the router in Bridge Mode and pointed me to how I can change it. Now the router indicted green but Internet was still amber. Following all this, when I tried connecting using my MacBook, I get the message that it has a self-assigned IP and cannot connect to the internet. I dont know what to do to make it work. I configured the same settings for the Ethernet adapter on my MacBook and Im able to connect to the internet. I dont know if this is helpful but thought Id put all the information I have on the forum.
