CAUTION After new settings are saved, the corresponding processes may be stopped and
restarted. When this happens, the WAP device may lose connectivity. We
recommend that you change WAP device settings when a loss of connectivity will
least affect your wireless clients.
WPS Setup
This section describes the Wi-Fi Protected Setup (WPS) protocol and its
configuration on the WAP device.
WPS is a standard that enables simple establishment of wireless networks
without compromising network security. It relieves both the wireless client users
and the WAP device administrators from having to know network names, keys, and
various other cryptographic configuration options.
WPS facilitates network setup by allowing the administrator to use a push button
or PIN to establish wireless networks, which avoids the manual entry of network
names (SSIDs) and wireless security parameters:
• Push button: The WPS button is either on the product or a clickable button
on the user interface.
• Personal Identification Number (PIN): The PIN can be viewed in the
product user interface.
WPS maintains network security by requiring both the users of new client devices
and WLAN administrators to have either physical access to their respective
devices or secure remote access to these devices.
These are typical scenarios for using WPS:
• A user wishes to enroll a client station on a WPS-enabled WLAN. (The
enrolling client device may detect the network, and prompt the user to
enroll, although this is not necessary.) The user triggers the enrollment by
pushing a button on the client device. The WAP device's administrator then
pushes a button on the WAP device. During a brief exchange of WPS
protocol messages, the WAP device supplies the new client with a new
security configuration through Extensible Authentication Protocol (EAP).
