Chapter 3 Wireless LAN Network 47
You can easily check to see if this has happened. WPS works between only two devices
simultaneously, so if another device has enrolled your device will be unable to enroll, and
will not have access to the network. If this happens, open the access point’s configuration
interface and look at the list of associated clients (usually displayed by MAC address). It
does not matter if the access point is the WPS registrar, the enrollee, or was not involved
in the WPS handshake; a rogue device must still associate with the access point to gain
access to the network. Check the MAC addresses of your wireless clients (usually printed
on a label on the bottom of the device). If there is an unknown MAC address you can
remove it or reset the AP.
3.4 Introduction to OTIST
In a wireless network, the wireless clients must have the same SSID and security settings as
the access point (AP) or wireless router (we will refer to both as “AP” here) in order to
associate with it. Traditionally this meant that you had to configure the settings on the AP and
then manually configure the exact same settings on each wireless client.
OTIST (One-Touch Intelligent Security Technology) allows you to transfer your AP’s SSID
and WEP or WPA-PSK security settings to wireless clients that support OTIST and are within
transmission range. You can also choose to have OTIST generate a WPA-PSK key for you if
you didn’t configure one manually.
3.4.1 Enabling OTIST
You must enable OTIST on both the AP and wireless client before you start transferring
settings.
We use the P-334WT in this guide as the example AP. Screens may vary slightly for your
ZyXEL devices.
Note: The AP and wireless client(s) MUST use the same Setup key .
3.4.1.1 AP
On the P-334WT, you can enable OTIST using the Reset button or the web configurator. If
you use the Reset button, the default (01234567) or previous saved (through the web
configurator) Setup key is used to encrypt the settings that you want to transfer.
Hold in the Reset button for one or two seconds.
Note: If you hold in the Reset button too long, the device may reset to the factory
defaults!
