5 On a computer connected to the wireless client, try logging into the NBG318S’s web
configurator. If you can connect, WPS was successful.
If you cannot connect, check the list of associated wireless clients in the AP’s
configuration utility. If you see the wireless client in the list, WPS was successful.
V If you cannot connect using WPS, check both devices’ configuration interfaces
to ensure WPS is enabled on both devices. If that doesn’t work, check you are
using the correct PIN. After you have generated a new PIN (see Section 7.9 on
page 101) the default PIN on the attached label is no longer valid.
7.4.2 How WPS Works
When two WPS-enabled devices connect, each device must assume a specific role. One device
acts as the registrar (the device that supplies network and security settings) and the other
device acts as the enrollee (the device that receives network and security settings. The registrar
creates a secure EAP (Extensible Authentication Protocol) tunnel and sends the network name
(SSID) and the WPA-PSK or WPA2-PSK pre-shared key to the enrollee. Whether WPA-PSK
or WPA2-PSK is used depends on the standards supported by the devices. If the registrar is
already part of a network, it sends the existing information. If not, it generates the SSID and
WPA(2)-PSK randomly.
The following figure shows a WPS-enabled client (installed in a notebook computer)
connecting to a WPS-enabled access point.
