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.
Figure 61
WPS: Example Network Step 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
.
Figure 62
WPS: Example Network Step 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
