What You Need to Know

Wireless Basics

“Wireless” is essentially radio communication. In the same way that walkie-talkie radios send and

receive information over the airwaves, wireless networking devices exchange information with one

another. A wireless networking device is just like a radio that lets your computer exchange

information with radios attached to other computers. Like walkie-talkies, most wireless networking

devices operate at radio frequency bands that are open to the public and do not require a license to

use. However, wireless networking is different from that of most traditional radio communications in

that there a number of wireless networking standards available with different methods of data

encryption.

screen. Set

Network Authentication

Open

and

WEP Encryption

Disabled

to allow

DESCRIPTION

Wireless Network Setup

Enable Wireless

Turn the wireless LAN on or off.

Hide Access

Point

Select this check box to hide the SSID in the outgoing beacon frame so a station cannot

obtain the SSID through scanning using a site survey tool.

Enable Wireless

Multicast

Forwarding

Select this check box to convert wireless multicast traffic into wireless unicast traffic.

SSID

The SSID (Service Set IDentity) identifies the service set with which a wireless device is

associated and serves as a name for the wireless network. Wireless devices associating to

the access point (AP) must have the same SSID.

Enter a descriptive name (up to 32 English keyboard characters) for the wireless LAN.

BSSID

This shows the MAC address of the wireless interface on the VDSL Router when wireless LAN

is enabled.

Max Clients

Set a limit for how many wireless clients can connect to the VDSL Router at a time.

Apply/Save

Click this button to save your changes.

DESCRIPTION

Enable WPS

Use WiFi Protected Setup (WPS) to quickly set up a wireless network without having to

manually configure settings. Set up each WPS connection between two devices at a time.

WPS is not available when using WPA or WPA 2.

Add Client

Use this section to add a wireless client to the wireless network.

Select

Push-Button

to add a client by pressing a button on the VDSL Router and the

wireless client. This is the easiest method.

Select

Enter STA PIN

to add a client by entering the client’s Personal Identification

Number (PIN) in the field that displays when you select this option.

Select

Use AP PIN

to add a client by entering the AP’s PIN from the

Device PIN

field in

the client’s WPS configuration.

Add Enrollee

Click this to use WPS to add a wireless client to your wireless network.

Note: You must also activate WPS on the client within two minutes.

Set WPS AP Mode

Configured

uses the VDSL Router’s current wireless security settings for WPS.

Unconfigured

has the VDSL Router change its wireless security settings when you do

one of the following:

•

Add a wireless enrollee. The VDSL Router automatically uses WPA2-PSK and a random

key. The

WPS AP Mode

automatically changes to

Configured

•

Use

Setup AP

to have an external registrar (like Windows Vista) configure the VDSL

Router’s wireless security settings. The

WPS AP Mode

automatically changes to

Configured

•

Manually configure the VDSL Router’s wireless security settings. Then you can

manually set the

WPS AP Mode

Configured

Device PIN

This shows the VDSL Router’s PIN. Enter this PIN in the external registrar within two

minutes of clicking

Config AP

Enter this PIN in the client’s WPS configuration if you selected

Use AP PIN

Config AP

Click

Config AP

to have an external registrar configure the VDSL Router’s wireless

security settings. See

Section 14.7.8 on page 196

for how to use Windows Vista as an

external registrar.

Push Button

and

are reserved for future use and have no effect

at the time of writing.

Note: After you click

Config AP

you must enter the VDSL Router’s PIN in the external

registrar within two minutes.

WPS Wireless ER

This is available when you set the

WPS AP Mode

Configured

Click

Enable/Disable

to have an external registrar such as an Intel wireless station use WPS to add wireless

clients and then authenticate them whenever they connect to the wireless network.

If you used a Windows Vista computer to configure the VDSL Router’s wireless settings,

you can also use the Windows Vista computer to add and authenticate wireless clients

without using

WPS Wireless ER

. See

Section 14.7.8 on page 196

for details.

Note: After you click

Enable/Disable

you must enter the VDSL Router’s PIN in the external

registrar within two minutes.

Then click

Enable/Disable

again.

WPS 2.0

Select this to support WPS 2.0.

Network

Authentication

Use the strongest authentication method that the wireless clients all support.

WPA2

WPA

uses an external RADIUS server to authenticate a separate user name

and password for each user. While WPA2 offers the strongest security, more wireless

clients support WPA.

Mixed WPA2/WPA

supports WPA and WPA2 simultaneously.

WPA2-PSK

WPA-PSK

uses a common password for all clients. While WPA2-PSK offers

stronger security, more wireless clients support WPA-PSK.

Mixed WPA2/WPA -PSK

supports WPA2-PSK and WPA-PSK simultaneously.

Choose

Open

to allow all wireless connections without authentication.

WPA2

Preauthentication

This field displays when you select

WPA2

Mixed WPA2/WPA

Enable pre-authentication for fast roaming by allowing a wireless client already connected

to an AP to perform IEEE 802.1x authentication with another AP before connecting to it.

Network Re-auth

Interval

This field displays when you select

WPA2

Mixed WPA2/WPA

Specify how often wireless stations have to resend usernames and passwords in order to

stay connected. If wireless station authentication is done using a RADIUS server, the

reauthentication timer on the RADIUS server has priority.

WPA Group Rekey

Interval

Set the rate at which the AP (if using WPA(2)-PSK key management) or RADIUS server (if

using WPA(2) key management) sends a new group key out to all clients. The re-keying

process is the WPA(2) equivalent of automatically changing the WEP key for an AP and all

stations in a WLAN on a periodic basis.

RADIUS Server IP

Address

Enter the IP address of the external authentication server in dotted decimal notation.

RADIUS Port

Enter the port number of the external authentication server. The default port number is

1812

. You need not change this value unless your network administrator instructs you to

do so with additional information.

RADIUS Key

Enter a password (up to 31 alphanumeric characters) as the key to be shared between

the external RADIUS server and the VDSL Router. The key must be the same on the

RADIUS server and your VDSL Router. The key is not sent over the network.

WPA/WAPI

Encryption

Select the encryption type (

AES

TKIP+AES

) for data encryption.

Select

AES

if your wireless clients can all use AES.

Select

TKIP+AES

to allow the wireless clients to use either TKIP or AES.

Generate

password

automatically

This field displays when you select WPA(2)-PSK.

Select this option to have the VDSL Router automatically generate a password. The

password field becomes read-only.

WPA/WAPI

passphrase

This field displays when you select WPA(2)-PSK.

Enter 16 to 63 alphanumeric characters (0-9, A-Z, with no spaces). It must contain both

letters and numbers and is case-sensitive. Click the link to display the password.

WEP Encryption

This field displays when you set

Network Authentication

Open

. Enable WEP

encryption to scramble the wireless data transmissions between the wireless stations and

the access points (AP) to keep network communications private. Both the wireless

stations and the access points must use the same WEP key.

Note: WEP is extremely insecure. Attackers can break it using widely-available software. It

is strongly recommended that you use a more effective security mechanism.

Encryption

Strength

If you are using WEP encryption, select

64-bit

128-bit

to set the length of the

encryption key.
