[. . . ] If you cannot connect, check the list of associated wireless clients in the AP's configuration utility. If you see the wireless client in the list, WPS was successful. 3 4 5 6 7 8 P-660HN-TxA User's Guide 129 Chapter 8 Wireless LAN The following figure shows a WPS-enabled wireless client (installed in a notebook computer) connecting to the WPS-enabled AP via the PIN method.

One device acts as the registrar (the device that supplies network and security settings) and the other device acts as the enrollee (the device that receives network and security settings. The registrar creates a secure EAP (Extensible Authentication Protocol) tunnel and sends the network name (SSID) and the WPAPSK or WPA2-PSK pre-shared key to the enrollee. Whether WPA-PSK or WPA2-PSK is used depends on the standards supported by the devices. If the registrar is already part of a network, it sends the existing information. If not, it generates the SSID and WPA(2)-PSK randomly. 130 P-660HN-TxA User's Guide Chapter 8 Wireless LAN The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a WPS-enabled access point. Figure 60 How WPS works ACTIVATE WPS WITHIN 2 MINUTES ACTIVATE WPS WPS HANDSHAKE ENROLLEE SECURE TUNNEL REGISTRAR SECURITY INFO COMMUNICATION The roles of registrar and enrollee last only as long as the WPS setup process is active (two minutes). The next time you use WPS, a different device can be the registrar if necessary. The WPS connection process is like a handshake; only two devices participate in each WPS transaction. If you want to add more devices you should repeat the process with one of the existing networked devices and the new device. Note that the access point (AP) is not always the registrar, and the wireless client is not always the enrollee. All WPS-certified APs can be a registrar, and so can some WPS-enabled wireless clients. This means that it is not part of an existing network and can act as either enrollee or registrar (if it supports both functions). If the registrar is unconfigured, the security settings it transmits to the enrollee are randomly-generated. Once a WPS-enabled device has connected to another device using WPS, it becomes "configured". A configured wireless client can still act as enrollee or registrar in subsequent WPS connections, but a configured access point can no longer act as enrollee. It will be the registrar in all subsequent WPS connections in which it is involved. If you want a configured AP to act as an enrollee, you must reset it to its factory defaults. P-660HN-TxA User's Guide 131 Chapter 8 Wireless LAN 8. 8. 8. 4 Example WPS Network Setup This section shows how security settings are distributed in an example WPS setup. The registrar randomly generates the security information to set up the network, since it is unconfigured and has no existing information. Figure 61 WPS: Example Network Step 1 ENROLLEE REGISTRAR SECURITY INFO CLIENT 1 AP1 In step 2, you add another wireless client to the network. You know that Client 1 supports registrar mode, but it is better to use AP1 for the WPS handshake with the new client since you must connect to the access point anyway in order to use the network. In this case, AP1 must be the registrar, since it is configured (it already has security information for the network). AP1 supplies the existing security information to Client 2.
