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.

2.4.4 Limitations of WPS
WPS has some limitations of which you should be aware.
• WPS works in Infrastructure networks only (where an AP and a wireless client
communicate). It does not work in Ad-Hoc networks (where there is no AP).
• When you use WPS, it works between two devices only. You cannot enroll
multiple devices simultaneously, you must enroll one after the other.
For instance, if you have two enrollees and one registrar you must set up the
first enrollee (by pressing the WPS button on the registrar and the first enrollee,
for example), then check that it successfully enrolled, then set up the second
device in the same way.
