If those unsupported modes are enforced by users, WPS
will be disabled
. Under the configuration of every WPS-
supported mode, Wireless Gateway has Push Button method
and PIN method . For each method, Wireless Gateway offers
different security levels included in network credential, such as
open security, WEP 64 bits, WEP 128 bits, WPA-Personal TKIP,
WPA-Personal AES, WPA2-Personal TKIP, and WPA2-
Personal AES. Users could choose either one of the methods at
their convenience.
AP mode
For AP mode, Wireless Gateway supports three roles, registrar,
proxy, and enrollee in registration protocol. At different
scenarios, Wireless Gateway 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 ESSID 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
Wireless Gateway also has a built-in internal registrar.
Whenever users enter station’s PIN into AP’s webpage, click
“Start PBC”, or 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,
ESSID 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.
