4.4.2 Wireless - Security Configure
Wireless security settings can be configured according to Wi-Fi Protected Setup
(WPS) or Manual Setup. The WPS method configures security settings automatically
(see 4.4.3 WPS) while the Manual Setup method requires that the user configure
these settings using the Web User Interface (see the table below).

64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10
hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26
hexadecimal numbers. Each key contains a 24-bit header (an initiation vector)
which enables parallel decoding of multiple streams of encrypted data.
Current Network Key
Select the required network key.

4.4.3 WPS Setup
Wi-Fi Protected Setup (WPS) is an industry standard that simplifies wireless security
setup for certified network devices. Every WPS certified device has both a PIN
number and a push button, located on the device or accessed through device
software. The NexusLink 5700 has both a WPS button on the device and a virtual
button accessible from the web user interface (WUI).
To configure security settings with WPS, follow the procedures below. You must
choose either the Push-Button or PIN configuration method for Steps 6 and 7.
I. Setup
Step 1: Enable WPS by selecting Enabled from the drop down list box shown.
22
Step 2: Set the WPS AP Mode. Configured is used when the NexusLink 5700.
will assign security settings to clients. Unconfigured is used when an external
client assigns security settings to the NexusLink 5700.
NOTES: Your client may or may not have the ability to provide security settings to
the NexusLink 5700. If it does not, then you must set the WPS AP mode to
Configured. Consult the device documentation to check its capabilities.
In addition, using Windows Vista, you can add an external registrar using
the StartAddER button (Appendix E - WPS OPERATION has detailed
instructions).
II. NETWORK AUTHENTICATION
Step 3: Select Open, WPA-PSK, WPA2-PSK, or Mixed WPA2/WPA-PSK network
authentication mode from the Manual Setup AP section of the Wireless
Security screen. The example below shows WPA2-PSK mode.
Step 4: For the Pre-Shared Key (PSK) modes, enter a WPA Pre-Shared Key. You
23
will see the following dialog box if the Key is too short or too long.
Step 5: Click the button at the bottom of the window.
IIIa. PUSH-BUTTON CONFIGURATION
The WPS push-button configuration provides a virtual button (accessible from the
web user interface) configuration method.
The WPS push-button configuration is described in the procedure below. It is
assumed that the Wireless function is Enabled and that the router is configured as
the Wireless Access Point (AP) of your WLAN. In addition, the wireless client must
also be configured correctly and turned on, with WPS function enabled.
NOTE: The wireless AP on the router searches for 2 minutes. If the router stops
searching before you complete Step 7, return to Step 6.
Step 6: WUI virtual button
Select the Push-Button radio button in the WPS Setup section of the
Wireless Security screen, and then click the appropriate button based on
the WPS AP mode selected in step 2.
For Configured mode, click the Add Enrollee button.
Step 7: Go to your WPS wireless client and activate the push-button function on
your NexusLink 5700.
A typical WPS client screenshot is shown below as an example.
24
Now go to Step 8 (part IV. Check Connection) to check the WPS connection.
IIIb. WPS – PIN CONFIGURATION
Using this method, security settings are configured with a personal identification
number (PIN). The PIN can be found on the device itself or within the software.
The PIN may be generated randomly in the latter case. To obtain a PIN number for
your client, check the device documentation for specific instructions.
The WPS PIN configuration is described in the procedure below. It is assumed that
the Wireless function is Enabled and that the router is configured as the Wireless
Access Point (AP) of your wireless LAN. In addition, the wireless client must also be
configured correctly and turned on, with WPS function enabled.
Step 6: Select the PIN radio button in the WPS Setup section of the Wireless
Security screen, as shown in A or B below, and then click the appropriate
button based on the WPS AP mode selected in step 2.
A - For Configured mode, enter the client PIN in the box provided and
then click the Add Enrollee button (see below).
B - For Unconfigured mode, click the Config AP button.
25
Step 7: Activate the PIN function on the wireless client. For Configured mode,
the client must be configured as an Enrollee. For Unconfigured mode,
the client must be configured as the Registrar. This is different from the
External Registrar function provided in Windows Vista.
The figure below provides an example of a WPS client PIN function in-progress.
Now go to Step 8 (part IV. Check Connection) to check the WPS connection.
IV. CHECK CONNECTION
Step 8: If the WPS setup method was successful, you will be able access the
wireless AP from the client. The client software should show the status.
The example below shows that the connection established successfully.
You can also double-click the Wireless Network Connection icon from the
Network Connections window (or the system tray) to confirm the status of
the new connection.
4.4.4 Wireless - Advanced Configure
The Advanced page allows you to configure advanced features of the wireless LAN
interface.
