Supported WPS features
AP mode
For AP mode, the device supports three roles, registrar, proxy, and enrollee in registration
protocol. At different scenarios, the device will automatically switch to an appropriate role
depending on the other device’s role or a specific configuration.
AP as Enrollee
If users know AP’s PIN and enter it into external registrar, the external registrar will configure AP
with a new wireless profile such as new SSID and new security settings. The external registrar
does this job either utilizing the in-band EAP (wireless) or out-of-band UPnP (Ethernet). During
the WPS handshake, a wireless profile is encrypted and transmitted to AP. If the handshake
is successfully done, AP will be re-initialized with the new wireless profile and wait for legacy
stations or WPS stations to join its network.
AP as Registrar
The device also has a built-in internal registrar. Whenever users push the physical button, AP will
switch to registrar automatically. If users apply the same method on station side and the WPS
handshake is successfully done, SSID and security settings will be transmitted to that station
without the risk of eavesdropping. And then the station will associate with AP in a security-
enabled network.
AP as Proxy
At this state, AP is transparent to users. If users want to configure a station or any device that
is capable of being an enrollee, they have to enter device’s PIN into an external registrar and
choose an appropriate wireless profile. After the PIN is entered, the external registrar will inform
AP this event. AP then conveys the encrypted wireless profile between the device and the
external registrar. Finally, the device will use the wireless profile and associate with AP. However,
the device may connect to other APs if the wireless profile does not belong to the proxy AP.
Users must carefully choose the wireless profile or create a wireless profile on an external
registrar.
