Wi-Fi Protected Setup (WPS) is a standard created by the Wi-Fi Alliance to allow home and small office users an easy way to configure Wi-Fi Protected Access security. The following WPS methods can be used to add new devices to existing secure wireless networks:
  • PBC: With the Push Button Configuration, a button (actual or virtual) is pushed on the access point, or a registrar of the network, and another button is pushed on the new wireless device that enables data encryption. During the setup period (approximately two minutes after you push the button), unintended devices could join a network if they are within range. Support of this model is mandatory for WPS certified access points and optional for new wireless devices.
  • PIN: A label with a Personal Identification Number is provided on each new wireless device that joins the network. A PIN may be dynamically generated on the device's display. When the new device is detected, you are prompted to enter the PIN at the wireless access point, or the registrar of the network. This is the mandatory baseline model that every WPS certified product must support.
  • NFC: Near Field Communication readers transfer the network settings to a new device without manually entering a PIN. When a new wireless device is moved within range of the access point, or registrar of the network, a near field communication is established that allows the PIN to be transferred. NFC Forum compliant RFID tags can also be used. Support of this model by manufacturers of WPS devices is optional.
  • UFD: A USB Flash Drive can also be used to transfer data between the new wireless device and the access point or registrar of the network. Support of this model by manufacturers of WPS devices is optional.
NOTE: Wi-Fi Protected Setup (WPS) does not work with Wired Equivalent Privacy (WEP) devices on the same network. Using even one WEP device on your network will not allow you to use Wi-Fi Protected Setup.
