Field Description
Disable WPS Checking Yes and clicking “Confirm” will disable Wi-Fi
Protected Setup. WPS is turned on by default.
WPS State When AP’s settings are factory default (out of box), it is set to
open security and un-configured state. It will be displayed by
“WPS Status”.
WPS PIN “WPS PIN” is AP’s PIN. Whenever users want to change AP’s
PIN, they could reboot the device.
Push Button (This
button is name WPS
and at the right side
of the device)
Press this button for 2 seconds will invoke the PBC method of
WPS. It is only used when AP acts as a registrar.
Introduction of WPS
Although home Wi-Fi networks have become more and more popular, users still have trouble
with the initial set up of network. This obstacle forces users to use the open security and
increases the risk of eavesdropping. Therefore, WPS is designed to ease set up of security-
enabled Wi-Fi networks and subsequently network management (Wi-Fi Protected Setup
Specification 1.0h.pdf, p. 8).
The largest difference between WPS-enabled devices and legacy devices is that users do not
need the knowledge about SSID, channel and security settings, but they could still surf in a
security-enabled Wi-Fi network. For examples, in the initial network set up, if users want to use
the PIN configuration, the only thing they need to do is entering the device PIN into registrar,
starting the PIN method on that device and simply wait until the device joins the network. After
the PIN method is started on both sides, a registration protocol will be initiated between the
registrar and the enrollee. Typically, a registrar could be an access point or other device that is
capable of managing the network. An enrollee could be an access point or a station that will join
the network. After the registration protocol has been done, the enrollee will receive SSID and
security settings from the registrar and then join the network. In other words; if a station attempts
to join a network managed by an access point with built-in internal registrar, users will need to
enter station’s PIN into the web page of that access point. If the device PIN is correct and valid
and users start PIN on station, the access point and the station will automatically exchange the
encrypted information of the network settings under the management of AP’s internal registrar.
The station then uses this information to perform authentication algorithm, join the secure
network, and transmit data with the encryption algorithm. More details will be demonstrated in
the following sections.
