 If you chose PPPoE, your ISP provides your IP address automatically using DHCP.
If your service provider asks you for the MAC address of your wireless device, use the
address of the Ethernet WAN port (<), printed on the label on the bottom of the
device.
If you’ve already used AirPort Utility to set up your wireless device, the fields below the
Configure IPv4 pop-up menu may already contain the information appropriate for your
service provider.
You can change the WAN Ethernet speed if you have specific requirements for the
network you’re connected to. In most cases, the settings that are configured
automatically are correct. Your service provider should be able to tell you if you need
to adjust these settings.
Changing the WAN Ethernet speed can affect the way the wireless device interacts with
the Internet. Unless your service provider has given you specific settings, use the
automatic settings. Entering the wrong settings can affect network performance.
Contact your service
provider for the
information you should
enter in these fields.
Use this pop-up menu
if you need to adjust
the speed of the
Ethernet WAN port.
