With the AirPort, a network of Macs can share a single IP address, and up to 10 users can connect to each other or to the Web via a single Base Station. You can also wirelessly network AirPort-equipped Macs without relying on a Base Station. However, don't expect to achieve the Ethernet-equivalent 11-Mbps throughput that Apple claims. The AirPort is plenty fast for a wireless connection, but it doesn't match 10BaseT Ethernet performance.

The AirPort comes with a special bracket for adding the card to an iMac DFV. You simply remove this bracket to install the card into another Mac model. After installing the software, you run the Setup Assistant, which lets you join an existing network or configure a Base Station.
