Wireless Network Name (SSID)

For the wireless network components to be able to communicate with one another, they

must use the same

SSID

(Service Set Identifier).

The SSID for the Gigaset SE587 WLAN dsl is individually preset. The preset SSID is shown

on the label on the bottom of the device (see page 4).

You can change the SSID if required and for security reasons you can deactivate SSID

broadcast.

ì

Enter a character string of your choice. The SSID is case-sensitive. It can contain up

to 32 characters. Use a combination of letters, digits and special characters.

Wireless Channel

All clients in the network use the same radio channel for wireless data transfer.

The channel is selected automatically by default (

Auto Channel

is enabled). If required,

you can choose manually between various channels, depending on your current loca-

tion.

To choose the channel manually:

ì

Disable the

Auto Channel

option.

ì

Select the

Wireless Channel

for your wireless network.

Wireless SSID broadcast

If this option is enabled (default setting), the Gigaset SE587 WLAN dsl will send the SSID

in all data transfers and the SSID of the Gigaset SE587 WLAN dsl will be displayed on PCs

that have a wireless network adapter. In this case, hackers could use the SSID to detect

your network.

If you deactivate

Wireless SSID broadcast

, the SSID of the Gigaset SE587 WLAN dsl will

not be displayed. This increases protection against unauthorised access to your wireless

network. Make a note of the SSID. You will need it to log on to the PC.

ì

Select

Disable

to deactivate

Wireless SSID broadcast

.

Wireless Security

For your security data transmission in your wireless network is encrypted by default.

Access to your wireless network is only granted to authenticated clients.

The Gigaset SE587 WLAN dsl is delivered with preset individual encryption (WPA-PSK/

WPA2-PSK with pre-shared key). You will find this key on the label on the bottom of the

device.

Note:

The connection to the wireless network adapters will be interrupted until you have

connected them with the new SSID.

If all components of your wireless network provide this encryption method there is no

need to change any settings on this page. If not, or if you want to change the preset key

(e. g. if unauthorised persons have access to your device), you can configure the

encryption for your wireless network on this page.

The following security mechanisms are available:

u

WPA-PSK

/WPA2-PSK (WiFi-Protected Access)

u

WEP

encryption (Wired Equivalent Privacy)

WPA-PSK (WPA with pre-shared key) offers greater security than WEP. You should there-

fore select WPA-PSK encryption if it is supported by all components in your wireless net-

work. WPA-PSK is an efficient method for protecting wireless networks. Dynamic keys,

based on the

AES

(WPA2-PSK) or

TKIP

(WPA-PSK), offer increased security.

ì

In the

Wireless Network

menu, select

Wireless Security

.

ì

Select the desired encryption method from the

Security Mode

option menu.

WPA-PSK and WPA2-PSK

ì

Select

WPA-PSK/WPA2-PSK

from the

Security Mode

option menu.

ì

Enter a key in the

WPA Shared key

field (up to 32 characters). Use a combination of

letters, digits and special characters.

ì

Click

Save Settings

to apply your settings.

Note:

If you change the encryption, wirelessly connected clients are disconnected until you

update the security setting on the wireless network adapters again.

WPA-PSK/WPA2-PSK

Select this option for WPA-PSK or WPA2-PSK encryption.

WEP

Select this option for WEP encryption.

Disabled

Select this option if you want to deactivate the encryption

of the wireless data transmission. It is not recommended to

deactivate encryption.

Note:

Make a note of the key that you have entered. You will need this information to con-

figure the wireless network adapters properly.

WEP encryption

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

that you activate

WEP Encryption

on the components.

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

are generated in hexadecimal format. You must use the same keys for encryption and

decryption for the Gigaset SE587 WLAN dsl and all your wireless network adapters.

ì

Select

WEP

from the

Security Mode

option menu.

ì

Select

64 bit

or

128 bit

from the

Key Length

option menu.

ì

If you don’t use an authentication server in your network keep the value

Open Sys-

tem

for the parameter

Authentication type

. Otherwise choose

Shared Key

.

You can enter up to four keys manually or generate them automatically by means of a

passphrase.

Generating keys by means of a Passphrase

ì

Enter a

Passphrase

(up to 32 characters).

ì

Click

to create the keys.

Generating keys manually

ì

Enter up to four keys in fields

Key 1

to

Key 4

.

–

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

An example of a valid key: 12-34-56-7A-BC

–

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

An example of a valid key: 23-45-67-AB-C8-91-23-45-DE-F1-23-45-67

Allowed characters are 0-9 and A-F.

ers properly.

u

When you have concluded the configuration you must change the WEP encryption

in the wireless network adapters for the connected PCs in the same way, as they

will not otherwise be given access to the wireless network of the Gigaset SE587

WLAN dsl.
