"external registrar," and triggers the WPS registration process at this UI. (On
a wired LAN, the WPS protocol messages are transported via the Universal
Plug and Play, or UPnP, protocol.) The host registers the AP as a new
network device and configures the AP with new security settings.
• An AP administrator has just added a new AP to an existing (wireless or
wired) network via WPS, and wishes to grant network access to a new
client device. The device is enrolled through either the "PIN" or "push button
control (PBC)" methods described above, but this time the device enrolls
with the external registrar, with the AP acting solely as a proxy.
• A wireless device that does not support WPS must join the WPS-enabled
WLAN. The administrator, who cannot use WPS in this case, instead
manually configures the device with the SSID, public shared key, and
cryptography modes of the WPS-enabled AP. The device joins the network.
The PIN is either an eight-digit number that uses its last digit as a checksum value,
or a four-digit number with no checksum. Each of these numbers may contain
leading zeroes.
The WPS standard assigns specific roles to the various components in its
architecture:
• —A device that can join the wireless network.
• —A device that provides wireless access to the network.
• —An entity that issues security credentials to enrollees and
configures APs.
The WAP121 can act as an AP and supports an internal registrar. It does not
function as a enrollee.
The administrator can enable or disable WPS on only one VAP. WPS is operational
only if this VAP meets the following conditions:
• The AP is configured to broadcast the VAP SSID.
• MAC address filtering is disabled on the VAP.
• WEP encryption is disabled on the VAP.
