Set up your AirPort Express to create a new network that wireless computers and devices
can use to connect to the Internet.

Set up your AirPort Express to join an existing network. If the network is connected to the
Internet, all the computers and wireless devices on the AirPort network can use the Internet
connection. If the network is set up to be extended, AirPort Express can extend the range
of that network.

You can do all of your basic network setup and configuration with the setup assistant in
AirPort Utility on a Mac or Windows computer, or with Wi-Fi settings on an iOS device. To manage
