Securing Your Wireless Connection

Introduction

You can protect the wireless communication between the wireless clients and your MediaAccess Gateway with a wireless key.

This means that:



Only clients which use the correct Network Name (SSID) and wireless key can connect to your network.



All data passing through your wireless access point is secured and encrypted.

Encryption types

Over the years a number of encryption types have been developed. The list below gives you an overview of the supported

encryption types ordered by descending security level; you will find the highest level of security at the top of the list:



WPA-PSK Encryption:

The wireless connection is secured with a pre-shared key that has been defined by the user. Wireless clients must be

configured with this key before they can connect to the MediaAccess Gateway. The MediaAccess Gateway supports the

following WPA-PSK versions (ordered by descending security):



WPA2-PSK:

The most recent and most secure version of WPA-PSK. Choose this version if you are sure that all your wireless clients

support WPA2-PSK.



WPA-PSK + WPA2-PSK

:

This is a mixed mode. In this mode WPA2-PSK, is the preferred encryption type but wireless clients do not support

WPA2-PSK, can still use WPA-PSK as encryption type. Choose this option if not all of your wireless clients support

WPA2-PSK or if you are not sure. Wireless clients that support WPA2-PSK will use WPA2-PSK, the others will use

WPA-PSK.



WPA-PSK

:

The first version of

WPA-PSK.

Choose this option if you are sure that none of your wireless clients support

WPA2-PSK.



WEP Encryption:

The least safe encryption type used for wireless connections. Like WPA-PSK it uses a user-defined key, but WEP has

been proven to have security issues.

Configuration

Proceed as follows:

1

Browse to the

MediaAccess Gateway GUI

.

For more information, see

“Accessing the MediaAccess Gateway GUI” on page 33

.

2

Under

Home Network

, click

Wireless

.

3

The

Wireless Access Point

page appears. In the upper-right corner, click

Configure

.

If you want to configure WPA2-PSK on the built-in wireless utility of Windows XP Service Pack 2 (SP2), you first

have to:



Upgrade your Windows XP to Service Pack 3.

- or -



Install the following update: http://support.microsoft.com/kb/917021

.

Although the MediaAccess Gateway allows you to use WEP or no security, we strongly advise against using one

of them! Use

WPA(2)-PSK

instead.

Telephony

Voice over IP (VoIP)

VoIP is a technology in which telephone calls are made over the Internet. This allows you to save on communication costs,

especially for long-distance calls.

The expensive solution

To be able to make your phone calls over the Internet you could either:



Buy an IP phone.

These IP phones are special phones that you can connect to your Internet Gateway.



Install VoIP software on your computer and make your phone calls via your computer.

The Technicolor solution

With the MediaAccess Gateway you can make both VoIP and traditional telephone calls using a traditional analogue phone.

If your MediaAccess Gateway is not powered, the traditional telephone network (if connected) will automatically selected.

This way you are still able to make emergency calls.
