Option Description Enable Wireless A checkbox þ that enables or disables the wireless LAN interface. When selected, a set of basic wireless options will appear. Hide Access Point Select Hide Access Point to protect the access point from detection by wireless active scans. To check AP status in Windows XP, open Network Connections from the start Menu and select View Available Network Connections. If the access point is hidden, it will not be listed there. To connect a client to a hidden access point, the station must add the access point manually to its wireless configuration. Clients Isolation When enabled, it prevents client PCs from seeing one another in My Network Places or Network Neighborhood. Also, prevents one wireless client communicating with another wireless client. PDF created with pdfFactory Pro trial version www.pdffactory.com
73 Option Description Disable WMM Advertise Stops the router from ‘advertising’ its Wireless Multimedia (WMM) functionality, which provides basic quality of service for time-sensitive applications (e.g. VoIP, Video). Enable Wireless Multicast Forwarding Select the checkbox þ to enable this function. SSID [1-32 characters] Sets the wireless network name. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that user will not be granted access. BSSID The BSSID is a 48-bit identity used to identify a particular BSS (Basic Service Set) within an area. In Infrastructure BSS networks, the BSSID is the MAC (Media Access Control) address of the AP (Access Point); and in Independent BSS or ad hoc networks, the BSSID is generated randomly. Country A drop-down menu that permits worldwide and specific national settings. Local regulations limit channel range: US= worldwide, Japan=1-14, Jordan= 10-13, Israel= 1-13 Max Clients The maximum number of clients that can access the router.

PDF created with pdfFactory Pro trial version www.pdffactory.com
74 6.2 Security The following screen appears when Wireless Security is selected. The options shown here allow you to configure security features of the wireless LAN interface. Click Save/Apply to implement new configuration settings. WIRELESS SECURITY Wireless security settings can be configured according to Wi-Fi Protected Setup (WPS) or Manual Setup. The WPS method configures security settings automatically (see 6.2.1 WPS) while the Manual Setup method requires that the user configure these settings using the Web User Interface (see the table below). Select SSID Select the wireless network name from the drop-down box. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that client will not be granted access. Network Authentication This option specifies whether a network key is used for authentication to the wireless network. If network authentication is set to Open, then no authentication is provided. Despite this, the identity of the client is still verified. Each authentication type has its own settings. For example, selecting 802.1X authentication will reveal the RADIUS Server IP address, Port and Key fields. WEP Encryption will also be enabled as shown below. PDF created with pdfFactory Pro trial version www.pdffactory.com
75 The settings for WPA authentication are shown below. The settings for WPA-PSK authentication are shown next. PDF created with pdfFactory Pro trial version www.pdffactory.com
76 WEP Encryption This option specifies whether data sent over the network is encrypted. The same network key is used for data encryption and network authentication. Four network keys can be defined although only one can be used at any one time. Use the Current Network Key list box to select the appropriate network key. Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm. WEP is a set of security services used to protect 802.11 networks from unauthorized access, such as eavesdropping; in this case, the capture of wireless network traffic. When data encryption is enabled, secret shared encryption keys are generated and used by the source station and the destination station to alter frame bits, thus avoiding disclosure to eavesdroppers. Under shared key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel. Encryption Strength This drop-down list box will display when WEP Encryption is enabled. The key strength is proportional to the number of binary bits comprising the key. This means that keys with a greater number of bits have a greater degree of security and are considerably more difficult to crack. Encryption strength can be set to either 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. 6.2.1 WPS 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 3111u has both a WPS button on the device and a virtual button accessible from the web user interface (WUI). Devices with the WPS logo (shown here) support WPS. If the WPS logo is not present on your device it still may support WPS, in this case, check the device documentation for the phrase “Wi-Fi Protected Setup”. NOTE: WPS is only available in Open, WPA-PSK, WPA2-PSK and Mixed WPA2/WPA-PSK network authentication modes. Other authentication modes do not use WPS so they must be configured manually. 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. PDF created with pdfFactory Pro trial version www.pdffactory.com
77 Step 2: Set the WSC AP Mode. Configured is used when the NEXUSLINK 3111u will assign security settings to clients. Unconfigured is used when an external client assigns security settings to the NEXUSLINK 3111u. NOTES: Your client may or may not have the ability to provide security settings to the NEXUSLINK 3111u. If it does not, then you must set the WSC 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 - WSC External Registrar 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 will see the following dialog box if the Key is too short or too long. PDF created with pdfFactory Pro trial version www.pdffactory.com
78 Step 5: Click the Save/Apply button at the bottom of the screen. IIIa. PUSH-BUTTON CONFIGURATION The WPS push-button configuration provides a semi-automated configuration method. The WPS button on the rear panel of the router can be used for this purpose or the Web User Interface (WUI) can be used exclusively. 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: First method: WPS button Press the WPS button on the rear panel of the router.
