Owner's Manual

NOTE: WPA-Personal (PSK) uses either WPA-PSK or WPA2-PSK authentication, based on the security protocols available
on the wireless router/AP.
computers on the infrastructure network to access the resources and tools of the wired LAN, including Internet access, e-mail,
file sharing, and printer sharing.
For the purposes of this user guide, infrastructure networks are classified as either basic networks or advanced networks.
A basic infrastructure network is a network that uses any of the following security types:
• WPA-Personal (PSK) authentication
• WEP (open or shared authentication)
• None
An advanced infrastructure network is typically used only in corporate environments and uses some form of Extensible
Authentication Protocol (EAP) (also called 802.1X) or Cisco Centralized Key Management (CCKM) authentication.
Ad Hoc Network
With an ad hoc network, wireless clients communicate directly with each other without the use of a wireless router/AP. This
type of network allows you to share files with other employees, print to a shared printer, and access the Internet through a
shared modem. With ad hoc networking, each computer that is connected to the network is able to communicate only with
other computers that are connected to the same ad hoc network and are within range.
Broadcasting Wireless Router/AP or Nonbroadcasting Wireless Router/AP
A broadcasting wireless router/AP broadcasts its network name (SSID), and a nonbroadcasting wireless router/AP does not.
Most wireless routers/APs in corporate environments are nonbroadcasting, and wireless routers/APs used today in home
office/small office environments can be configured to be nonbroadcasting. It is important to know whether the network you
want to connect to is broadcasting or nonbroadcasting.
