1 Run the provided telephone cable from the wall jack providing ADSL

service to the ADSL port on your ADSL Router. When inserting an ADSL RJ-11 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. If you are using splitterless ADSL service, add low-pass filters between the ADSL wall jack and your telephones. (These filters pass voice signals through but filter data signals out.)

2 Then:

■ If you are using a full-rate (G.dmt) connection, your service provider

will attach the outside ADSL line to a data/voice splitter. In this case

you can connect your phones and computer directly to the splitter as

shown below (Figure 6

■ If you are using a splitterless (G.lite) connection, then your service

provider will attach the outside ADSL line directly to your phone

system. In this case you can connect your phones and computer

directly to the incoming ADSL line, but you will have to add low-pass

filters to your phones as shown below (Figure 7

)

IP addresses to each computer on your network. The factory default settings for the DHCP server will work in most any application. If you need to make changes to the settings, you can do so.

The changes that you can make are:

■ Change the Internal IP address of the Router. The default is

192.168.1.1

■ Change the Subnet Mask. The default is 255.255.255.0

■ Enable/Disable the DHCP Server Function. Default is ON (Enabled)

■ Specify the Starting and Ending IP Pool Address. Default is Starting: 2 /

Ending: 254

■ Specify the IP address Lease Time. Default is Half day

■ Specify a local Domain Name. Default is NONE

To make changes, click LAN Settings on the main menu.

The Router will also provide you with a list of all client computers connected to the network.

DHCP Clients List

The DHCP Clients List provides details on the devices that have received IP addresses from the Router. The list is only created when the Router is set up as a DHCP server. For each device that is connected to the LAN the following information is displayed:

■ IP address — The Internet Protocol (IP) address issued to the client

machine.

■ Host Name — The client machine’s host name, if configured.

■ MAC Address — The Media Access Control (MAC) address of the

client’s network card.

■ Client Type — Whether the client is connected to the Router by wired

or wireless connection.

As you connect more devices, the client list will grow to a maximum number of 253 clients.

From this section of the screen, you can do the following:

■ In the table, check the Fix text box to permanently fix the IP address.

■ In the table, click Release to release the displayed IP address.

■ Click New to allocate an IP address to a MAC address. If you click

New, a screen similar to that shown in Figure 28

will be displayed.

Enter the required details and click Apply to save your settings.

To enable Wireless function:

1 Select the Wireless Channel you want to use from the Channel

drop-down list.

2 Specify the SSID to be used by your Wireless Network in the SSID field. If

there are other wireless networks in your area, you should give your wireless network a unique name.

3 Enable or disable SSID Broadcast.

A feature of many wireless network adapters is that a computer's SSID can be set to ANY, which means it looks randomly for any existing wireless network. The available networks are then displayed in a site survey, and your computer can select a network. By clicking disable, you can block this random search, and set the computer's SSID to a specific network (for example, WLAN). This increases network security. If you decide to enable SSID Broadcast, ensure that you know the name of your network first.

4 In the Wireless Mode drop down list, select whether your router will

operate in 11b mode only, 11g mode only, or mixed 11b and 11g.

5 Click Apply.

Encryption This feature prevents any non-authorized party from reading or changing

your data over the wireless network.

Figure 31 Encryption Screen

From this screen, you can select the wireless security mode that you want to use. There are five selections:

■ Disabled (see page 41)

Page 43

Wireless Settings 41

■ WPA-PSK (no Server) (see page 41)

■ 128-bit WEP (see page 42)

■ 64-bit WEP (see page 43)

■ WPA (with RADIUS Server) (see page 44)

Select the required value from the drop down list, and press Apply.

Disabled

In this mode, wireless transmissions will not be encrypted, and will be visible to everyone. However, when setting up or debugging wireless networks, it is often useful to use this security mode.

WPA-PSK (no server)

WPA (WiFi Protected Access) provides dynamic key changes and constitutes the best security solution. In a wireless network where not all devices support WPA, WEP (Wired Equivalent Privacy) should be used.

Figure 32 WPA-PSK (no server) Screen

To enable WPA-PSK:

1 Enter the pre-shared key in the Pre-shared Key (PSK) field. The pre-shared

key is a password, in the form of a word, phrase or series of letters and numbers. The key must be between 8 and 63 characters long and can include spaces and symbols.

Note that each client that connects to the network must use the same key.

2 Optionally, check the Hide PSK check box, if you want the key that you

enter to be shown on the screen as a series of asterisks (*).

3 Click Apply.

128-bit WEP

WEP is the basic mechanism to transmit your data securely over the wireless network. Matching encryption keys must be setup on your Router and wireless client devices to use WEP.

Figure 33 128-bit WEP Screen

To enable 128-bit WEP:

1 You can enter the 128-bit WEP key manually:

■ enter your WEP key as 13 pairs of hex digits (0-9, A-F).

Or you can generate the 128-bit WEP key automatically:

■ enter a memorable passphrase in the Passphrase box, and then

click Generate to generate the hex keys from the passphrase.

The WEP keys on each device on the wireless network must be identical.

In 128-bit WEP mode, only one WEP key (key 1) can be specified.

2 Click Apply.

Wireless Settings 43

64-bit WEP

WEP is the basic mechanism to transmit your data securely over the wireless network. Matching encryption keys must be setup on your Router and wireless client devices to use WEP.

Figure 34 64-bit WEP Screen

To enable 64-bit WEP:

1 Manually enter the key:

■ enter the WEP key as 5 pairs of hex digits (0-9, A-F).

Automatically generate the key:

■ enter a memorable passphrase in the Passphrase box, and then click

Generate to generate the hex keys from the passphrase.

For 64-bit WEP, you can enter up to four keys, in the fields Key 1 to Key 4. The radio button on the left hand side selects the key that is used in transmitting data.

Note that all four WEP keys on each device in the wireless network must be identical.

2 Click Apply.

4 Select the encapsulation type (LLC or VC MUX) in the Encapsulation field.

This information will have been provided to you by your ISP.

5 Select the type of Quality of Service (CBR, UBR or VBR) in the QoS field.

■ CBR (constant bit rate): the CBR service class is intended for

real-time applications, for example, those requiring tightly constrained delay and delay variation, such as voice and video applications. The consistent availability of a fixed quantity of bandwidth is considered appropriate for CBR service.

■ UBR (unspecified bit rate): the UBR service class is intended for

delay-tolerant or non-real-time applications, for example, those which do not require tightly constrained delay and delay variation, such as traditional computer communications applications. The UBR service may be considered as "best effort service".

Page 50

48 CHAPTER 5: CONFIGURING THE ROUTER

■ VBR (variable bit rate): QoS class defined by the ATM Forum for

ATM networks. VBR is subdivided into a real time (RT) class and non-real time (NRT) class. VBR (RT) is used for connections in which there is a fixed timing relationship between samples. VBR (NRT) is used for connections in which there is no fixed timing relationship between samples, but that still need a guaranteed QoS. Compare with ABR, CBR, and UBR.

6 Enter the PCR/SCR/MBS values. 7 Select the connection type from the Connect Type drop-down menu.

■ Always Connected means that Internet connection to your ISP is

always on.

■ Auto - Triggered by Traffic means your Router will automatically

connect to your ISP every time a PC needs to access the Internet.

■ Manual - Start in Disconnected means that after re-booting the

Router, the Internet connection will need to be re-established manually by the user.

■ Manual - Start in Connected means that after re-booting the

Router, it will automatically establish connection to your ISP.

■ Manual - Start in Last State means that after re-booting the Router,

the Internet connection will stay in the previous condition before the reboot.
