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.

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.

In step 3, you add another access point (AP2) to your network. AP2 is out of range of AP1, so you cannot 
use AP1 for the WPS handshake with the new access point. However, you know that Client 2 supports 
the registrar function, so you use it to perform the WPS handshake instead.
