Ethernet if you are connecting to a wired network, or AirPort if you are connecting to a

name, password, and PPPoE service name (if your service provider requires it).

Network Connections
Make sure the Ethernet cable is connected to your MacBook Pro and to the network.
Check the cables and power supplies to your Ethernet hubs and routers.
If you have two or more computers sharing an Internet connection, be sure that your
network is set up properly. You need to know if your ISP provides only one IP address
or if it provides multiple IP addresses, one for each computer.
If only one IP address is provided, then you must have a router capable of sharing the
connection, also known as network address translation (NAT) or “IP masquerading.”
For setup information, check the documentation provided with your router or
ask the person who set up your network. You can use an AirPort base station to
share one IP address among multiple computers. For information about using an
AirPort base station, check Mac Help or go to the Apple AirPort website at
www.apple.com/support/airport.
If you cannot resolve the issue using these steps, contact your ISP or network
administrator.
