User Guide
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.

WPS works by automatically issuing a randomly-generated WPA-PSK or WPA2-PSK pre-
shared key from the registrar device to the enrollee devices. Whether the network uses WPA-
PSK or WPA2-PSK depends on the device. You can check the configuration interface of the
registrar device to discover the key the network is using (if the device supports this feature).
Then, you can enter the key into the non-WPS device and join the network as normal (the
non-WPS device must also support WPA-PSK or WPA2-PSK).

You can easily check to see if this has happened. WPS works between only two devices
simultaneously, so if another device has enrolled your device will be unable to enroll, and will
not have access to the network. If this happens, open the access point's configuration interface
and look at the list of associated clients (usually displayed by MAC address). It does not
matter if the access point is the WPS registrar, the enrollee, or was not involved in the WPS
handshake; a rogue device must still associate with the access point to gain access to the
network. Check the MAC addresses of your wireless clients (usually printed on a Label on the
bottom of the device). If there is an unknown MAC address you can remove it or reset the AP.

WPS works only with other WPS-enabled devices. However, you can still add non-WPS
devices to a network you already set up using WPS.
WPS 2.0 does not allow the use of WPA-PSK.
When you use the PBC method, there is a short period (from the moment you press the
button on one device to the moment you press the button on the other device) when any
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.
