SSID
For the wireless network components to be able to communicate with one another, you
must use the same
SSID
(Service Set Identifier).
The default SSID for the Giga762SX WLAN dsl is shown at the label on the bottom of the
device. For security reasons you can change this SSID and deactivate SSID broadcast. If
this option is enabled, the Giga762SX WLAN dsl will send the SSID in all data transfers
and the SSID of the Giga762SX WLAN dsl will be displayed on PCs that have a wireless
network adapter. In this case, unauthorised persons could use the SSID to gain access to
your network.
If you have performed a successful WPS registration before a manual configuration of
security data, this page shows the generated SSID. Make a note of this SSID. You will
need it to manually configure the wireless network adapters that do not support WPS.
ì
If you are using WPS registration, click on
Next >
.
ì
Enter a character string of your choice in the
SSID
field. The SSID is case-sensitive. It
can contain up to 32 characters. Use a combination of letters, digits and special char-
acters.
ì
Deactivate
SSID broadcast
and make a note of the SSID. You will
need for further wireless connections to the Giga762SX WLAN
dsl.

Click

.
Note:
The connection to the wireless network adapters will be inter-
rupted until the new SSID has also been entered.

Setting up security functions for the wireless network
Wireless networks are even more susceptible to eavesdropping than wired networks.
With conventional network adapters, an intruder only needs a device with a WLAN
adapter (e.g. a notebook or a PDA [Personal Digital Assistant]) with an appropriately
configured network card in order to eavesdrop on every communication made via a
nearby wireless LAN.
The Giga762SX WLAN dsl makes use of effective encryption methods to prevent unau-
thorised eavesdropping as far as possible.
The Giga762SX WLAN dsl is delivered with preset individual encryption (WPA2-PSK/
WPA-PSK with pre-shared Key). You will find this key at the label on the devices bottom.
If all components of your wireless network provide this encryption method there is no
need of any settings in this screen. If not, or if you want to change the preset key (e. g.
if unauthorised persons may have access to your device), you can configure the encryp-
tion for your wireless network in the next step.
You can use the following security mechanisms:
u
WPA2-PSK, WPA-PSK or WPA2-PSK/WPA-PSK (page 54)
u
WEP encryption (Wired Equivalent Privacy, see page 56)
You will find further options for setting up data encryption and authentication in the
Advanced Settings
menu (page 87).
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.
ì
If you do not want to change the encryption settings, click on
Next >
.
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.
ì
By clicking the
Unmask
button, a message showing the pre-
shared key is output in readable characters.
ì
To go to the next step, click
Next >
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.

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 55), 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 Giga762SX 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
.
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.

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
Next >
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
Giga762SX WLAN dsl wireless network.
