Adapters and access points
Adapters
While some devices, such as the printer, have built-in Wi-Fi capability, other devices
need an adapter to become Wi-Fi-enabled.

documentation for installation and configuration instructions.
Access points
A common variety of wireless network is called an
infrastructure network . An
infrastructure network requires the use of a Wireless Access Point (WAP) .
A WAP acts as a central hub for a wireless network or as a router connecting the
wireless network to another network (such as the Internet or an Ethernet network).
Devices on the network communicate through the WAP.
Macintosh users may use an AirPort® Base Station as a WAP.
