6.13.2 Security 2.4GHz

The following screen appears when Wireless Security is selected. The options shown
here allow you to configure security features of the wireless LAN interface.

Please see 6.13.3 for WPS setup instructions.
Click Apply/Save to implement new configuration settings.

WIRELESS SECURITY

Setup 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 menu. 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 gr anted access.

Network Authentication

This option specifies whether a network key is used for authenticat ion to the
wireless network. If network authe ntication is set to Open, then no authenti cation
is provided. Despite this, the iden tity 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.

Different authentication type pops up different settings requests.

113

Choosing 802.1X, enter RADIUS Server IP address, RADIUS P ort, RADIUS key and
Current Network Key.

Also, enable WEP Encryption and select Encryption Strength.

Select the Current Network Key and enter 13 ASCII characters or 26 hexadecimal
digits for 128-bit encryption keys and enter 5 ASCII characters or 10 hexadecimal
digits for 64-bit encryption keys.

Choosing WPA2-PSK, you must enter WPA Pre-Shared Key and Group Rekey
Interval.

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.

114

Security options include authentication and encryption services based on the wire d
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 wire less 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 en abled. 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 grea ter 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.

115

6.13.3 WPS 2.4GHz

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 3240 has a WPS button on the device.

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 .

I. Setup

Step 1: Enable WPS by selecting Enabled from the drop down list box shown.

Step 2: Set the WPS AP Mode. Configured is used when the NexusLink 3240 will

assign security settings to clients. Unconfigured is used when an
external client assigns security settings to the NexusLink 3240.

NOTES: Your client may or may not have the ability to provide security settings to

the NexusLink 3240. If it does not, then you must set the WPS AP mode
to Configured. Consult the device documentation to check its capabilities.

116

IIa. PUSH-BUTTON CONFIGURATION

The WPS push-button configuration provides a semi-automated configuration
method. The WPS button on the front panel of the router can be used for this
purpose.

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 4, return to Step 3.

Step 3: Press WPS button

Press the WPS button on the front panel of the router. The WPS LED will

blink to show that the router has begun searching for the client.

Step 4: Go to your WPS wireless client and activate the push-button function.
A typical WPS client screenshot is shown below as an example.

Now go to Step 7 (part III. Check Connection) to check the WPS connection.

IIb. 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 conf igured 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 5: Select the PIN radio button in the WSC Setup section of the Wireless

Security screen, as shown in A or B below , and then click the appropriate
button based on the WSC AP mode selected in step 2.

A - For Configured mode, click the Add Enrollee button.

117

Enter STA PIN: a Personal Identification N umber (PIN) has to be read from either
a sticker or the display on the new wireless device. This PIN must then be inputted
at representing the network, usually the Access Point of the network.

B - For Unconfigured mode, click the Config AP button.

Step 6: Activate the PIN functio n on the wi reless client. For Configured mode,

the client must be configured as an Enrollee. For Unconfigured mode,
the client must be configured as the Registr ar. 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.

III. CHECK CONNECTION

Step 7: 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 Wirele ss Network Connection icon from the

Network Connections window (or the system tr ay) to confirm the status of
the new connection.

54g Rate Drop-down menu that specifies the following fixed rates:

Auto: Default. Uses the 11 Mbps data rate when possible
but drops to lower rates when necessary. 1 Mbps, 2Mbps,

5.5Mbps, or 11Mbps fixed rates. The appropriate setting

is dependent on signal strength.
Multicast Rate Setting for multicast packet transmit rate (1-54 Mbps)
Basic Rate Setting for basic transmission rate.
Fragmentation

Threshold

A threshold, specified in bytes, that determines whether

packets will be fragmented and at what size. On an

802.11 WLAN, packets that exceed the fragmentation

threshold are fragmented, i.e., split into, smaller units

suitable for the circuit size. Packets smaller than the

specified fragmentation threshold value are not

fragmented. Enter a value between 256 and 2346. If you

experience a high packet error rate, try to slightly increase

your Fragmentation Threshold. The value should remain

at its default setting of 2346. Setting the Fragmentation

Threshold too low may result in poor performance.

123

Field Description

RTS Threshold Request to Send, when set in bytes, specifies the packet

size beyond which the WLAN Card invokes its RTS/CTS

mechanism. Packets that exceed the specified RTS

threshold trigger the RTS/CTS mechanism. The NIC

transmits smaller packet without using RTS/CTS. The

default setting of 2347 (maximum length) disables RTS

Threshold.
DTIM Interval Delivery T raffic Indication Message (DTIM) is also known as

Beacon Rate. The entry range is a value between 1 and

65535. A DTIM is a countdown variable that informs clients

of the next window for listening to broadcast and multicast

messages. When the AP has buffered broadcast or

multicast messages for associated clients, it sends the next

DTIM with a DTIM Interval value. AP Clients hear the

beacons and awaken to receive the broadcast and

multicast messages. The default is 1.
Beacon Interval The amount of time between beacon transmissions in

milliseconds. The default is 100 ms and the acceptable

range is 1 – 65535. The beacon transmissions identify the

presence of an access point. By default, network devices

passively scan all RF channels listening for beacons coming

from access points. Before a station enters power save

mode, the station needs the beacon interval to know when

to wake up to receive the beacon (and learn whether there

are buffered frames at the access point).
Global Max Clients The maximum number of clients that can connect to the

router.

Chapter 7 Voice

This chapter first describes the various options for configuration of the SIP voice
service. It then provides detailed instructions for making telephone calls using VoIP
(Voice over IP) or PSTN (Public Switched Telephone Network) services. Session
Initiation Protocol (SIP) is a peer-to-peer protocol used for Internet conferencing,
telephony, events notification, presence and instant messaging.
SIP is designed to address the functions of signaling and session management
within a packet telephony network. Signaling allows call information to be carried
across network boundaries. Session management provides the ability to control
the attributes of an end-to-end call.





NOTE: The SIP standard is set by the Internet Engineering Task Force (IETF).

The SIP standard defines the following agents/servers:

• User Agents (UA) - SIP phone clients (hardware or software)

• Proxy Server – relays data between UA and external servers

• Registrar Server - a server that accepts register requests from UA

• Redirect Server – provides an address lookup service to UA

The following subsections present Basic, Advanced and Debug SIP screens.
