Figure 24   How WPS works

The roles of registrar and enrollee last only as long as the WPS setup process is active (two 
minutes). The next time you use WPS, a different device can be the registrar if necessary.

The WPS connection process is like a handshake; only two devices participate in each WPS 
transaction. If you want to add more devices you should repeat the process with one of the 
existing networked devices and the new device.

Note that the access point (AP) is not always the registrar, and the wireless client is not always 
the enrollee. All WPS-certified APs can be a registrar, and so can some WPS-enabled wireless 
clients.

By default, a WPS devices is “unconfigured”. This means that it is not part of an existing 
network and can act as either enrollee or registrar (if it supports both functions). If the registrar 
is unconfigured, the security settings it transmits to the enrollee are randomly-generated. Once 
a WPS-enabled device has connected to another device using WPS, it becomes “configured”. 
A configured wireless client can still act as enrollee or registrar in subsequent WPS 
connections, but a configured access point can no longer act as enrollee. It will be the registrar 
in all subsequent WPS connections in which it is involved. If you want a configured AP to act 
as an enrollee, you must reset it to its factory defaults.
