How AirPort Provides Wireless Internet Access
With AirPort Extreme technology, your iMac makes a wireless connection to an AirPort
Express or AirPort Extreme Base Station, which is connected to the Internet via a
telephone line or a DSL modem or cable modem.
Note: You need an AirPort Express or AirPort Extreme Base Station and Internet access
(fees may apply). Some Internet service providers aren’t compatible with AirPort. Range
may vary with site conditions.
