Wireless Web Page Group

The Wireless web pages group enables a variety of settings that can provide secure and reliable wireless

communications for even the most demanding tech-savvy user.

The Wireless Voice Gateway offers a choice of 802.11b/g/n, WPA and WPA-PSK authentication of your

PCs to the gateway, 64 and 128 bit WEP encryption of communication between the gateway and your

PCs to guaranty security, and an Access Control List function that enables you to restrict wireless access

to only your specific PCs.

Performance

Because your wireless communication travels through the air, the factory default wireless channel setting

may not provide optimum performance in your home if you or your neighbors have other interfering

2.4GHz or 5 GHz devices such as cordless phones. If your wireless PC is experiencing very sluggish or

dramatically slower communication compared with the speed you achieve on your PC that is wired to the

gateway, try changing the channel number. See the 802.11b/g/n Basic Web Page discussion below for

details.

Authentication

Authentication enables you to restrict your gateway from communicating with any remote wireless PCs

that aren’t yours. The following minimum authentication

-related changes to factory defaults are

recommended. See the 802.11b/g/n Basic and Access Control Web Page discussions below for details.

Security

Security secures or scrambles messages traveling through the air between your wireless PCs and the

gateway, so they can’t be observed by others. The following minimum security setting changes to factory

defaults are recommended. See the 802.11b/g/n Security Web Page discussion below for details.

802.11x Authentication introduction

If you enable the

802.11x authentication

function, you will have to offer the following information-



WPA

(Wi-Fi Protected Access)

/WPA2

:

It must be used in conjunction with an authentication server such as RADIUS to provide centralized

access control and management. It can provide stronger encryption and authentication solution than

none WPA modes.

WPA2

is the second generation of

WPA

security.



WPA-PSK

(WPA-Pre-Shared Key)

/WPA2-PSK

(WPA2-Pre-Shared Key)

:

It is useful for small places without authentication servers such as the network at home. It allows the

use of manually-entered keys or passwords and is designed to be easily set up for home users.



RADIUS Server:

RADIUS Server is a protocol for carrying authentication, authorization, and

configuration information between a Network Access Server which desires to authenticate its links

and a shared Authentication Server. Please key in the IP Address for the RADIUS Server.



RADIUS Port:

Besides the IP address of the RADIUS Server, you have to enter the port number for

the server. Port 1812 is the reserved RADIUS-authentication port described in RFC 2138. Earlier AP

(RADIUS clients) use port 1945. The default value will be shown on this box. You can keep and use

it.



RADIUS Key:

A RADIUS Key is like a password, which is used between IAS and the specific

RADIUS client to verify identity. Both IAS and the RADIUS client must be use the same RADIUS

Key for successful communication to occur. Enter the RADIUS Key.
