    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. P-870HW-51a v2 User’s Guide...

    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. P-870HW-51a v2 User’s Guide...

    WPS-enabled device could join the network. This is because the registrar has no way of identifying the “correct” enrollee, and cannot differentiate between your enrollee and a rogue device. This is a possible way for a hacker to gain access to a network. P-870HW-51a v2 User’s Guide...
