[. . . ] 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 following figure shows an example network. In step 1, both AP1 and Client 1 are unconfigured. When WPS is activated on both, they perform the handshake. In this example, AP1 is the registrar, and Client 1 is the enrollee. 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.

AP2 is out of range of AP1, so you cannot use AP1 for the WPS handshake with the new access 132 P-660HN-TxA User's Guide Chapter 8 Wireless LAN point. However, you know that Client 2 supports the registrar function, so you use it to perform the WPS handshake instead.

It does not work in Ad-Hoc networks (where there is no AP). · When you use WPS, it works between two devices only. You cannot enroll multiple devices simultaneously, you must enroll one after the other. For instance, if you have two enrollees and one registrar you must set up the first enrollee (by pressing the WPS button on the registrar and the first enrollee, for example), then check that it successfully enrolled, then set up the second device in the same way. · WPS works only with other WPS-enabled devices. However, you can still add non-WPS devices to a network you already set up using WPS. WPS works by automatically issuing a randomly-generated WPA-PSK or WPA2PSK pre-shared key from the registrar device to the enrollee devices. Whether the network uses WPA-PSK or WPA2-PSK depends on the device. You can check the configuration interface of the registrar device to discover the key the network is using (if the device supports this feature). [. . . ] If this device does cause harmful interference to radio/television reception, which can be determined by turning the device off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 1 2 3 Reorient or relocate the receiving antenna. Increase the separation between the equipment and the receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. 4 FCC Radiation Exposure Statement · This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
