You do not need to enter any information. Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC button in their configuration utilities instead of or in addition to the physical button.

If the device does not have one, log into its configuration utility and locate the button (see the device's User's Guide for how to do this - for the VMG, see Figure 40 on page 95). 3 Press the button on one of the devices (it doesn't matter which). For the VMG you must press the WPS button for more than five seconds. 4 Within two minutes, press the button on the other device. The registrar sends the network name (SSID) and security key through an secure connection to the enrollee.

Push Button Configuration
WPS Push Button Configuration (PBC) is initiated by pressing a button on each WPS-enabled device, and
allowing them to connect automatically. You do not need to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC button in their
configuration utilities instead of or in addition to the physical button.
Take the following steps to set up WPS using the button.
1
Ensure that the two devices you want to set up are within wireless range of one another.
2
Look for a WPS button on each device. If the device does not have one, log into its configuration utility
and locate the button (see the device’s User’s Guide for how to do this - for the VMG, see
Figure 40 on
page 95
).
3
Press the button on one of the devices (it doesn’t matter which). For the VMG you must press the WPS
button for more than five seconds.
4
Within two minutes, press the button on the other device. The registrar sends the network name (SSID)
and security key through an secure connection to the enrollee.
If you need to make sure that WPS worked, 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.
7.8.8.2
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 WPA2-PSK pre-
shared key to the enrollee. If the registrar is already part of a network, it sends the existing information. If
not, it generates the SSID and WPA2-PSK randomly.
The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a
WPS-enabled access point.
