Configure VPI and VCI

Follow the instructions below to configure the virtual connection.

To configure the virtual connection, follow these steps:

1.

Enter the values for the

VPI

and

VCI

given to you by your service provider.

2. Select

Enable

from the

Virtual Circuit

pull-down menu to make the connection

active. If you prefer to leave the connection inactive leave this as

Disable

, and

activate it when it is needed.

3.

Choose the type of connection used for the virtual connection and configure the

settings according to the instructions of your service provider.

4. Click the

Save Settings

button to save the configuration. If you want to establish

the connection now, click the

Connect

button.

VPI

- The Virtual Path Identifier is used with the VCI to define a dedicated circuit on the ATM network portion of the connection to the Internet and WAN. Most users

will not need to change this setting.

VCI

- The Virtual Channel Identifier is used with the VPI to define a dedicated circuit on the ATM network portion of the connection to the Internet and WAN. Most

users will not need to change this setting.

Virtual Circuit

- Use this to enable or disable the PVC you are currently configuring. By default, the PVC0 is set to

Enable

.

ATM Traffic Shaping

Settings used for ATM traffic shaping are located beneath the VPI/VCI configuration menu. These settings allow the user to adjust ATM Quality of Service (QoS) or

traffic parameters to suit specific traffic requirements. For applications or circumstances where packet loss or packet delay is a concern, ATM QoS can be adjusted to

minimize problems. For most accounts, it will not be necessary to change these settings. Altering QoS settings can adversely affect performance of some commonly

used Internet applications.

If you plan to change QoS or traffic parameters, contact your ISP or network services provider for information on what types of adjustment are available or possible

for your account. Your ISP may not support the class of service you want to use.

To adjust ATM QoS parameters, select one of the Service Categories listed here and type in the PCR value in the entry field below. For the VBR service category,

an additional parameter (SCR) must also be defined.

UBR

– Unspecified Bit Rate, this is the default category used for general-purpose Internet traffic where normal levels of packet loss and delay are acceptable. For

some applications or for multiple connection accounts, it may be desirable to specify the PCR.

CBR

– Constant Bit Rate, usually used in circumstances where very low packet loss and very low Cell Delay Variable (CDV) are desirable.

VBR-r

t – Real-time Variable Bit Rate. This models bursty traffic with specified peak and sustainable rates. Please note that when VBR-rt is specified, both PCR and

SCR are required (by ATM standards).

VBR-nrt

– Non-real-time Variable Bit Rate, usually used when network traffic is characterized by bursts of packets at variable intervals, and some moderate packet

loss and delay is acceptable. This category is typically used for audio and video applications such as teleconferencing. The network must support QoS Class 2 to

use VBR-nrt.

Depending on which

Service Category

is selected, it will be necessary to change one or more of the following parameters:

PCR

- Peak Cell Rate – The PCR is inversely related to the time interval between ATM cells. It is specified for all three service categories (UBR, CBR and VBR) in Kbps.

SCR

- Sustainable Cell Rate – The SCR is defined for the VBR service category. This is the rate that can be sustained for “bursty”, on-off traffic sources. It is a function

of Maximum Burst Size (

MBS

) and the time interval (between cells).

Wireless Setup

The Router’s basic wireless and wireless network security settings are configured in the

Wireless Settings

configuration menu. To access this menu, click on the

Wireless Setup

link in the left panel of the

Setup

menu directory. It is the first page that appears when you successfully access the Web manager.

The

Wireless Settings

menu presents three options for configuration. Choose from

one of the three following configuration procedures:

1. Launch the

Wireless Network Setup Wizard

to configure the Network Name

(SSID) and WPA wireless network security. Click the

Wireless Network Setup

Wizard

button to begin. This option is recommended for most users.

Note

: The Wireless Network Setup Wizard uses WPA wireless network

security. If you wish to configure WEP wireless network security, use Manual

Wireless Network Setup.

2. Use the

WPS (Wi-Fi Protected Setup) Wizard

to add individual wireless clients.

Click the

Add Wireless Device with WPS

button to use begin configuration

with WPS.

Note

: Wireless clients added to using this method must support WPS.

3.

Configure the SSID, channel and wireless network security settings manually.

Click the

Manual Wireless Network Setup

button to go to the general wireless

network settings menu.

Wireless Network Setup Wizard

Click on the

Wireless Network Setup Wizard

button in the

Wireless Settings

menu to begin configuration of basic wireless network settings and WPA wireless

network security.

In the first Wireless Setup Wizard menu, enter the name used for the wireless

network in the

Network Name (SSID)

entry field. The

SSID

or Service Set Identifier

is the name used for the wireless network or a part of the wireless network. Wireless

clients must use this SSID in order to access the wireless network and use the

Router.

To configure WPA wireless network security, the Wizard menu offers two options. The

easiest and recommended method will configure WPA network key automatically.

To automatically configure WPA network security, choose the option

Automatically

assign a network key

and click on the

Next

button to complete the wireless

configuration. The new

Pre-Shared Key

and WPA wireless security settings are

displayed in the

Setup Complete!

menu. For later reference, be sure to print this

menu; or copy the new automatically created Pre-Shared Key and paste it into a

document to be saved. Click on the

Save

button to save the new wireless settings.

The automatically created pre-shared key is randomly generated.

Note

: For future reference, print out the

wizard menu

that lists the

,

Cipher Type

, and most importantly, the

.

To manually enter the WPA network key, click the
