Field Description
Push Button
Configuration
Clicking this button will invoke the PBC method of WPS. It is only
used when AP acts as a registrar.
Apply Changes Whenever users want to enable/disable WPS or change AP’s PIN,
they need to apply this button to commit changes.
Reset It restores the original values of “Self-PIN Number” and “Client PIN
Number”.
Client PIN Number It is only used when users want their station to join AP’s network.
The length of PIN is limited to four or eight numeric digits. If users
enter eight digit PIN with checksum error, there will be a warning
message popping up.
If users insist on this PIN, AP will take it.
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.
Supported WPS features
Currently, Wireless Gateway supports WPS features for AP
mode, AP+WDS mode, Infrastructure-Client mode, and the
wireless root interface of Universal Repeater mode.
