WPA2/WPA with pre-shared key (PSK)

WPA

is a more advanced procedure than WEP for protecting wireless networks. Dynamic

keys, based on TKIP (Temporal Key Integrity Protocol), offer increased security. The new

standard WPA2 uses

AES

(Advanced Encryption Standard) for encryption.

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.

This page shows the preset encryption settings.

.

If you yo want to change the pre-shared key:

ì

Select

WPA2-PSK

if WPA2 is supported by all components in the wireless network.

ì

Select

WPA-PSK

only if WPA is supported by all components in the wireless network.

ì

Select

WPA2-PSK / WPA-PSK

if only some components in the wireless network sup-

port WPA.

ì

Enter a key of your choice in the

Pre-shared key

field (min. 8 to max. 63 characters)

and confirm it by repeating the entry. You must set up the same pre-shared key for

all wirelessly connected PCs. Use a combination of letters, digits and special charac-

ters.

Note:

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

must also support WPA. Information about this can be found in the operating manual

for your network adapter.

By clicking the

Unmask

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

readable characters.

WEP encryption

WEP (Wired Equivalent Privacy) is an encryption for radio signals in wireless networks

and meets the IEEE 802.11 standard.

If you transmit data wirelessly and not all components in your wireless network support

the higher security standard WPA (page 56), we recommend that you activate

WEP

Encryption

.

WEP encryption and WPS registration cannot be used together in a wireless network.

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 Gigaset SX763 WLAN dsl and all your wireless network

adapters.

ì

Select the

Key length

: 64 bits or 128 bits.

ì

Select the

Input type

, i.e. whether the key is to be entered manually or generated

automatically by means of a

Passphrase

.

58

Security Setup Wizard

Manual key entry

ì

Select the

Key type

,

Hex

or

ASCII

.

If you select

Hex

as the key type you can use the characters

0

to

9

and

A

to

F

.

–

With a 64-bit encryption depth, the key is 10 characters long.

–

With a 128-bit encryption depth, the key is 26 characters long.

If you select

ASCII

as the key type, you can use the characters

0

to

9

,

A

to

Z

,

a

to

z

plus the special characters in the ASCII character set.

–

With a 64-bit encryption depth, the key is 5 characters long.

–

With a 128-bit encryption depth, the key is 13 characters long.

ì

Confirm the key by entering it again in the

Confirm key

field.

Generating a key by means of a Passphrase

ì

Enter a

Passphrase

(up to 32 characters) and confirm it by entering it again. The key

is generated automatically.

ì

To go to the next step, click

Note:

u

It is very

important

that you make a note of the key or passphrase. You will need

this information to configure the wireless network adapters properly.

u

You have to change the WEP encryption in the wireless network adapters for the

connected PCs in the same way, otherwise they will not be given access to the

Gigaset SX763 WLAN dsl wireless network.

Access control within the wireless network

In this step you can specify which PCs will have wireless access to the Gigaset SX763

WLAN dsl and hence to the LAN. Access control is based on the

MAC address

of the PC

network adapters. You can enter the MAC addresses for the PCs manually or select these

from the list of PCs that are currently logged in.

Access control is disabled by default. This means that all PCs that use the correct

SSID

can be logged in.

ì

Next to the

MAC address filter

, select

On

to activate the MAC filter.

Entering MAC addresses manually

ì

Enter the MAC address of the network adapter. You will find this address on the

underside of the device.

ì

Enter the name of the PC.

ì

Click the

Add

button to add the entry to the list.

Selecting from the list of logged-in PCs

ì

Select the required PC from the

Known wireless clients

list. All PCs that were

already entered manually on the router with the MAC address are displayed.

ì

Click the

Add

button to add the selected PC to the list.

Note:

If you activate MAC access control, you must at least add the PC on which you are con-

figuring the Gigaset SX763 WLAN dsl to the list. Otherwise, you will have no access

to the user interface and will receive an appropriate error message.

WPS registration is only possible for PCs in the list if you have activated MAC access

control.

If you have inadvertently denied all PCs access to the Gigaset SX763 WLAN dsl, you

have two options:

u

You can completely reset the Gigaset SX763 WLAN dsl (page 27).

u

You can connect a PC to the Gigaset SX763 WLAN dsl using one of the LAN con-

nections (by cable). As MAC access control only affects PCs that are connected

wirelessly, you can use this PC to change the configuration.
