3.4.3.1 Example WPS Network Setup
This section shows how security settings are distributed in an example WPS setup.
The following figure shows an example network. In step 1, both AP1 and Client 1 are
unconfigured. When WPS is activated on both, they perform the handshake. In this example,
AP1 is the registrar, and Client 1 is the enrollee. The registrar randomly generates the security
information to set up the network, since it is unconfigured and has no existing information.

CLIENT 1
In step 2, you add another wireless client to the network. You know that Client 1 supports
registrar mode, but it is better to use AP1 for the WPS handshake with the new client since
you must connect to the access point anyway in order to use the network. In this case, AP1
must be the registrar, since it is configured (it already has security information for the
network). AP1 supplies the existing security information to Client 2.
