AirPort Extreme Wireless Connection
If your iMac G5 has an AirPort Extreme Card installed, you can configure your AirPort
network and Internet connection using AirPort Setup Assistant, located in the Utilities
folder within your Applications folder. The assistant helps you configure the AirPort
Base Station and set up your computer to use AirPort Extreme. For more information
about your AirPort Base Station, see the AirPort Base Station Setup Guide that came with
your base station. For information on installing an AirPort Extreme Card, see “Installing
an AirPort Extreme Card” on page 47.
If your AirPort Base Station is already configured, in most cases your AirPort Extreme
Card is ready to access it immediately.
To check if you have access to an AirPort Extreme network:
m
Click the AirPort status icon in the menu bar and choose an AirPort network listed
there.
If you don’t see an AirPort network listed, you can use AirPort Setup Assistant to check
or change your settings, or you can change them using the Network pane of System
Preferences.
Setting Up an AirPort Extreme Connection Manually
Gather the following information from your system administrator if you’ll be setting up
a manual connection.
If you’ll be connecting using DHCP, most of this information is provided to your
computer automatically by the network, so ask your system administrator what is
required.
• Domain name server (DNS) addresses, if necessary
• DHCP or manual IP address configuration
• IP address
• Router address
• Subnet mask
• Password, if required
Next, make sure your AirPort connection options are active in Network preferences.
