receives the Giga762SX WLAN dsl security data (SSID and pre-shared key) and is

thereby registered.

The registration progress is shown in the window.

You can also follow the registration process via the LED display (see page 33).

If more than one client tries to register within the two minutes, an error message

is displayed. You may retry the WPS registration after a short time.

If an external client succeeds in registering, the LED (see page 33) displays a suc-

cessful WPS registration. The desired client in you network, however, has no con-

nection to the Giga762SX WLAN dsl and displays a registration failure. In this case

you should change the pre-shared key (WPA2-PSK/WPA-PSK) as soon as possible

and then perform WPS registration via PIN (see below).

–

Send own PIN

An automatically generated PIN is shown.

If you want to create a new PIN, click

Generate PIN

.

Click

OK

to activate your settings.

Enter the generated PIN on all WLAN partner devices that are to establish a

connection.

–

Enter partner device PIN

You would use this option if you have created a PIN at the desired client. Enter the

PIN of the WLAN partner device and click

OK

to activate your settings.

Setting encryption

If you are sending data over radio channels, we recommend that you activate encryp-

tion (

WEP

or

WPA

) on the components in the wireless network. WPA offers greater secu-

rity than WEP. You should therefore select WPA encryption if it is supported by all com-

ponents in your wireless network.

WPA also supports the use of an authentication server.

Note:

If you have activated access control via the MAC address filter, you have to include the

clients in the MAC address list before registering via WPS (see page 95).

Note:

The Giga762SX WLAN dsl is delivered with preset individual encryption (WPA2-PSK/

WPA-PSK with pre-shared key). You should change this settings only, if not all com-

ponents of your wireless network provide this encryption method, or if you want to

change the preset key for security reasons, or if you want to use the WDS repeater

function.

If you change the preset key after having registered PCs at the Giga762SX WLAN dsl

via WPS or manually, you must register all PCs again manually or via WPS.

menu select:

Encryption & Authentication

The following security mechanisms are currently available:

u

WPA2-PSK, WPA-PSK and WPA2-PSK/WPA-PSK (page 90)

u

WPA2 and WPA2/WPA with authentication server (page 90)

u

WEP encryption (Wired Equivalent Privacy, see page 92)

WPA2-PSK and WPA2-PSK / WPA-PSK

Note:

If you want to use the repeater function of your Giga762SX WLAN dsl (page 96) you

can only use WEP encryption.

Note:

This screen allows you to display the pre-shared key. You can change the encryption

here. In this case, you also have to configure all wireless network adapters manually

or perform WPS registration once again.

WPA with a pre-shared key (WPA-PSK)

WPA-PSK

is a special WPA mode for private users and users in small companies without

their own authentication server. After a certain period of time (

Rekey interval

), encryp-

tion keys are automatically generated with the pre-shared key, automatically changed

("rekeying") and authenticated between the devices.

The standard of encryption available to you depends on the components in the wireless

network. Every PC (network adapter) that requires access to a WPA-protected wireless

network must also support WPA. To find out whether and how you can use WPA on your

PC, read your network adapter's user guide. If all components support WPA2, select

WPA2-PSK

. If you are using network adapters that only support WPA, select

WPA-PSK

.

Select

WPA2-PSK / WPA-PSK

if both methods are used in your network. Your device

then automatically defines the best possible way to protect your data for each client.

The entries described below are identical for both options.

ì

Select the required option in the

Security

field.

ì

Enter a key in the

Pre-shared key

field (up to 32 characters) and confirm it by enter-

ing it again. Use a combination of letters, digits and special characters.

ì

By clicking the

Unmask

button, a message showing the pre-shared key is output in

readable characters.

ì

Apply the settings by clicking

OK

.

WPA and WPA2 with authentication server

In large networks (e.g. in companies) WPA enables the use of an additional authentica-

tion service. In this case, user access is controlled by user accounts and passwords, in

addition to WPA encryption. A RADIUS server acts as an authentication server. You can

select the new

WPA2

standard if it is supported by all components in your wireless net-

work. Select

WPA2 / WPA

if you are using devices that only support WPA.

WEP encryption

If WPA is not supported by all components in your wireless network, we recommend

that you activate

WEP Encryption

on the components.

ì

Choose the

WEP

option in the

Security

field.

ì

Select the

Authentication type

:

–

Select

Shared

to require that each client log in to the network with a specified

key.

–

Select

Open

to permit data transfer within the wireless network without the need

to enter a key.

You can choose either the standard 64-bit key or the more robust 128-bit key. The keys

are generated in hexadecimal or in ASCII format. You must use the same keys for encryp-

tion and decryption for the Giga762SX WLAN dsl and all your wireless network adapters.

ì

Select the

Key length

: 64 bits or 128 bits.

Note:

You cannot use WEP together with WPS.
