Configuring wireless connections

If PCs are communicating wirelessly via the Gigaset SE551 WLAN dsl/cable, you should

also take steps to enhance the security of your wireless network. You make this config-

uration via the

Advanced Settings

–

Wireless Network

menu. Here you can

u

activate the Gigaset SE551 WLAN dsl/cable's wireless module (see below),

u

set the channel and

SSID

(see page 71),

u

set

Encryption

for wireless transmissions (see page 74), and

u

restrict access to the Gigaset SE551 WLAN dsl/cable's LAN (see page 74),

u

configure the repeater function on the Gigaset SE551 WLAN dsl/cable.

ì

In the

Advanced Settings

menu, select

Wireless Network

.

ì

Select the

On

option for

Wireless Network

(default setting).

Devices can only log in wirelessly if the Gigaset SE551 WLAN dsl/cable's wireless

module is activated.

You can now make the settings for your wireless network.

Channel

This function is only shown in the window if the Super G transmission mode is deacti-

vated (see page 73).

The set radio channel is used by all clients in your network for wireless data transfer.

You can choose between various channels, depending on your current location.

ì

Select

Automatic

so that the best channel for transmitting the data is used automat-

ically.

Configuring the Advanced Settings

SSID

Before the wireless network components can communicate with each other, you must

use the same

SSID

(Service Set Identifier).

The default SSID for the Gigaset SE551 WLAN dsl/cable is

ConnectionPoint

. For security

reasons you should change this SSID and deactivate SSID broadcast (see below).

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

32 alphanumerical characters long.

SSID broadcast

If this option is enabled (default setting), the Gigaset SE551 WLAN dsl/cable will send

the SSID in all data transmissions, and your Gigaset SE551 WLAN dsl/cable's SSID will be

displayed on PCs that have a wireless network adapter. In this case eavesdroppers could

use the SSID to gain access to your network.

If you deactivate

SSID broadcast

, your Gigaset SE551 WLAN dsl/cable's SSID will not be

displayed. This increases the protection against unauthorised access to your wireless

network. However, you must make a note of the SSID. You will need this to log on your

PC.

ì

Select the

Off

option to deactivate

SSID broadcast

.

Transmission mode

This function is only shown in the window if the Super G transmission mode is deacti-

vated (see page 73).

The standard IEEE 802.11g permits data transfer up to 54 Mbit/s, IEEE 802.11b up

to 11 Mbit/s. For the best possible data transfer rates in your network select

IEEE 802.11g only

. To operate clients with older wireless network adapters in your

network, select

IEEE 802.11b/g (mixed)

.

ì

Select the required transmission mode for your wireless network.

Sending power

ì

Select the required sending power for your device.

We recommend that you select a sending power with a range to suit the spatial envi-

ronment of your local network. A much greater range makes it easier to eavesdrop

on your wireless data transmission.

Please remember:

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

the new SSID on them as well.

Super G (108 Mbit/s)

With the aid of channel bundling, the

Super G

transmission mode enables wireless data

transfer up to 108 Mbps. The channel for wireless data transfer cannot be changed. You

can only use Super G if this function is supported by at least one client in your wireless

network. For the best possible data transfer rates, all clients in your LAN should support

Super G.

ì

Select the mode for using

Super G (108 Mbit/s)

for your wireless network to incre-

ase the data transmission speed. You have a choice of two modes.

–

Static

: Wireless transmission is at a rate of just 108 Mbps. Clients that do not

support this speed cannot connect to Access Point.

–

Dynamic

: If you select this transmission mode, the router accepts subscribers

that communicate at different transfer rates and adjusts to the slowest client in

the network.

ì

If you do not wish to use

Super G (108 Mbit/s)

, select

Disabled

in the selection

menu.

XR (extended range)

Activating XR enables data transfer even in the peripheral areas of your wireless net-

work, albeit at very low data transfer rates. Conversion to XR mode occurs automatically

when the signal is weak enough and if the partner station is also XR capable.

ì

Activate or deactivate

XR

for your wireless network to increase the range.

ì

Click on

OK

to apply the settings.

Please remember:

If you activate Super G as the transmission mode, but it is not supported by all compo-

nents in your wireless network, then for technical reasons the transfer rate in the net-

work may be significantly lower than the possible maximum of 108 Mbit/s.

Configuring the Advanced Settings

Setting wireless security

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

tion (

WEP

or

WPA

) on your wireless network components. WPA offers greater security

than WEP. We therefore recommend that you choose WPA encryption if it is supported

by all components in your wireless network.

WPA

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

keys based on TKIP (Temporal Key Integration Protocol) offer increased security. The

new standard WPA2 is based on AES.

WPA also supports the use of an authentication server.

ì

In the

Wireless Network

menu, select

Encryption

.

The following security mechanisms are currently available:

u

WPA2-PSK and WPA2-PSK / WPA-PSK (see page 75)

u

WAP2 and WPA2 / WPA with authentication server (see page 76)

u

WEP encryption (Wired Equivalent Privacy) (see page 77)

75

Configuring the Advanced Settings

WPA2-PSK and WPA2-PSK / WPA-PSK

WPA with Pre-shared key (WPA-PSK)

WPA-PSK

is a special WPA mode that provides encryption protection for users at home

and in small companies without a company authentication server. Encryption keys

are automatically generated with the Pre-shared key, and automatically changed

(rekeying) and authenticated between the devices after a certain period of time (

Rekey

Interval

).

Which standard of encryption you can choose depends on the components in your wire-

less network. Every PC (network adapter) that requires access to a wireless network pro-

tected by WPA must also support WPA. To find out whether and how you can use WPA

on your PC, read your network adapter's operating instructions. If all components sup-

port WPA2, select option

WPA2-PSK

. If you are using network adapters that only sup-

port WPA, select the option

WPA2-PSK / WPA-PSK

. The entries described below are the

same 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 alphanumerical characters) and

confirm it by entering it again.

ì

Apply the settings by clicking

OK
