Wired local network (Ethernet)
In a wired local network, PCs communicate with one another via an Ethernet cable.
When the Gigaset SE551 WLAN dsl/cable is used, it establishes the connection between
the PCs. For this it has four Ethernet LAN ports for connecting four PCs. The PCs have to
be equipped with a network socket (Ethernet). New PCs frequently already have this
socket. For older PCs you need to install an Ethernet network card. The PC and the Ethernet LAN socket on the Gigaset SE551 WLAN dsl/cable are connected using an Ethernet
cable (CAT5). There is one supplied. You can obtain additional Ethernet cables from your
retailer.
The Gigaset SE551 WLAN dsl/cable allows all PCs to access the Internet simultaneously.

Wireless local network (WLAN)
In a wireless local network (WLAN) PCs are linked without wires. For this the PCs
have to be equipped with a wireless network adapter (WLAN adapter) such as a
Gigaset PC Card 108 or a USB Adapter 108.
We generally differentiate between two types of wireless network:
u Infrastructure mode
u Ad-hoc mode
Infrastructure mode
The infrastructure mode connects wireless and wired networks with one another. In
addition to the mobile stations, the infrastructure mode needs an access point such as
the Gigaset SE551 WLAN dsl/cable. In infrastructure mode the stations in the network
always communicate via this access point. Each station that wants to be part of the wireless network must first register with the access point before it can exchange data.
The access point establishes the connection between the mobile stations of a wireless
network and a wired LAN (Ethernet) or the Internet. In this case this is described as the
device's router functionality. The router sends data packets that are not addressed to stations within the network "outside" and forwards data packets originating from "outside"
to the appropriate station within the network.
You can use the Gigaset SE551 WLAN dsl/cable to connect
u wirelessly networked PCs to the Internet and
u wirelessly networked PCs to an Ethernet network.
Infrastructure mode is the default configuration of the Gigaset SE551 WLAN dsl/cable.
This configuration is described in the quick guide enclosed with the router.
Ad-hoc mode
An ad-hoc network is a wireless network set up without an access point or router.
The mobile network components that communicate with each other directly and without wire connections form the network "ad-hoc", i.e. as and when required. All the
stations in the network have the same rights. Ad-hoc networks are used wherever
communications networks have to be set up quickly and without any existing network
infrastructure, and where the participants are on the move.

Linking wireless networks with the Internet
The Gigaset SE551 WLAN dsl/cable has an ADSL interface that permits all stations within
its local network to access the Internet simultaneously. To be able to use this functionality you need a DSL or cable connection obtainable from an Internet provider. Find out
whether your Internet Service Provider supports parallel access by several PCs.

This illustration shows the commonest method of application. One or more PCs communicate wirelessly with the Gigaset SE551 WLAN dsl/cable in infrastructure mode. The
Gigaset SE551 WLAN dsl/cable forwards the data to the Internet via a DSL or cable
modem. Data from the Internet flows back to the PC along the same route.

Linking a wireless network (WLAN) to an Ethernet (LAN)
Wireless networks can work easily together with existing Ethernet networks. If you wish
to connect mobile stations to an existing wired network, you must group together all
mobile stations into a wireless network in infrastructure mode.

Ethernet
The Gigaset SE551 WLAN dsl/cable has four Ethernet interfaces (LAN ports). Up to four
PCs can be connected directly to these LAN ports.
All PCs can access the Internet via the Gigaset SE551 WLAN dsl/cable.
Please remember:
You can also connect an Ethernet router to a LAN port to access a larger Ethernet.
If you want to link the Gigaset WLAN network to an existing network, a large number
of settings have to be applied. Therefore we cannot provide a general example for this
use; the configuration depends greatly on the networks in question. We advise having
the configuration of such a network carried out by a specialist.

Page 21
First Steps
To t he PC
You can connect wired or wireless PCs to your Gigaset SE551 WLAN dsl/cable to create
a local network (LAN).
Wireless
A wireless connection is made using a wireless network adapter that must be installed
in your PC. This can be, for example, a Gigaset PC Card 108, a Gigaset USB Adapter 108
or another Super G, 802.11g or 802.11b-compatible wireless network adapter.
You def ine a Radio network by assigning all the devices an identical SSID. You should
therefore assign the SSID of the Gigaset SE551 WLAN dsl/cable to the network adapters.
The factory set SSID is ConnectionPoint.
If the correct SSID has been entered in your PC's wireless network adapter, the wireless
link will be established automatically once you connect your Gigaset SE551 WLAN dsl/
cable to the mains power supply (see page 20).
21
Page 22
First Steps
Wired
ì Connect one of the LAN sockets (LAN1 – LAN4) on the back of the Gigaset SE551
WLAN dsl/cable to the Ethernet connection on a PC. To do this, use an Ethernet cable
with RJ-45 jacks (CAT5). This can also be done with the supplied Ethernet cable.
The four LAN sockets can automatically set the transmission speed to 10 Mbps
Ethernet or 100 Mbps Fast Ethernet and the transmissions mode to Half duplex or
Full duplex depending on the performance of the network adapter in your PC.
22
Page 23
First Steps
To the mains power supply
Please remember:
Only use the router with the mains adapter (12V 1A DC) that is supplied.
ì Connect the mains adapter cable to the 12V DC socket on the Gigaset SE551 WLAN
dsl/cable.
ì Plug the mains adapter into a mains socket.
Your Gigaset SE551 WLAN dsl/cable is now ready for use.
u The power LED on the front lights up.
u The WLAN LED lights up to indicate that the Gigaset SE551 WLAN dsl/cable is ready
to open wireless connections.
The radio link to a PC that is connected by means of a wireless network adapter is
opened automatically provided the network adapter has been configured with the
same SSID as the Gigaset SE551 WLAN dsl/cable (see page 21). It can take a few seconds for the wireless connection to be established. The WLAN LED flashes when
data is sent or received via this connection.
u The LAN LEDs light up if a device is connected to the corresponding LAN connection
by means of an Ethernet cable.
In order to communicate via the Gigaset SE551 WLAN dsl/cable, the network must be
configured on the connected PC. This usually takes place automatically.
You will find information on how to operate devices on the USB port of the Gigaset

Security settings
Setting security functions for the wireless network
In the next step you can set the encryption and authentication methods for your wireless network.
Wireless networks are even more strongly exposed to the risk of 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 Gigaset SE551 WLAN dsl/cable makes use of effective encryption methods to prevent unauthorised eavesdropping as far as possible.
You can use the following security mechanisms:
u WPA2-PSK or WPA2-PSK / WPA-PSK (see below)
u WEP encryption (Wired Equivalent Privacy, see page 39)
We recommend using WPA2-PSK if it is supported by all components in your wireless
network.
You will find further options for setting data encryption and authentication in the
Advanced Settings menu (see page 74).
37
Page 38
Security settings
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 Integration Protocol) offer increased security. The
new standard WPA2 uses AES for the encryption.
WPA-PSK is a special WPA mode for users at home and in small companies without a
company authentication server. Encryption keys are automatically generated with the
Pre-shared key, automatically changed ( "rekeying") and authenticated between the
devices after a certain period of time (Rekey Interval).
Please remember:
Every PC (network adapter) that requires access to a wireless network protected 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.
ì Select the option WPA2-PSK if it is supported by all components in your wireless
network.
or
ì Select the option WPA2-PSK / WPA-PSK if some or all components in your wireless
network support WPA with the TKIP protocol.
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 also set the same Pre-shared key for all wirelessly connected PCs.
ì To go to the next step, click on Next >.
38
Page 39
Security settings
WEP encryption
WEP (Wired Equivalent Privacy) is an encryption procedure for radio signals in wireless
networks and meets the standard IEEE 802.11.
If you transmit data wirelessly and not all components in your wireless network support
the higher security standard WPA (see page 38), we recommend that you activate WEP-
Encryption on these network components.
You can choose either the standard 64-bit key or the more robust 128-bit key for encryption. The keys are generated in hexadecimal or in ASCII format. You must use the same
keys for encryption and decryption for the Gigaset SE551 WLAN dsl/cable and all your
wireless network adapters.
ì Select the Key length: 64 bit or 128 bit.
ì Select the Input type, i.e. whether you wish to enter the key manually or have it
generated automatically by means of a Passphrase.
39
Page 40
Security settings
Manual key entry
ì Select the Key type, Hex or ASCII.
.
If you select Hex you can use the characters 0 to 9 and A to F.
– With a 64-bit encryption depth the key is exactly 10 characters long.
An example of a valid key: 1234567ABC
– With a 128-bit encryption depth the key is exactly 26 characters long.
An example of a valid key: 234567ABC8912345DEF1234567
If you select ASCII you can use the characters 0 to 9, A to Z and a to z plus the special
characters in the ASCII character set.
– With a 64-bit encryption depth the key is exactly 5 characters long.
An example of a valid key: GIGA1
– With a 128-bit encryption depth the key is exactly 13 characters long.
An example of a valid key: GIGASET_SE551
ì Confirm the key by entering it again in the Confirm key field.
Generating the 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.
Please remember:
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 When you have concluded the Security Setup Wizard you must change the
WEP encryption on the wireless network adapters for the connected PCs in the
same way as they will not otherwise be given access to the Gigaset SE551
WLAN dsl/cable's wireless network.

ì To go to the next step in the Security Setup Wizard, click on Next >.
Access control within the wireless network
In this step you can specify which PCs will have wireless access to the Gigaset SE551
WLAN dsl/cable and hence to your LAN. The access control is based on the MAC address
of the PCs' network adapters. You can enter the MAC addresses for the PCs manually or
select them from the list of PCs that are currently logged in.
The default setting for access control is disabled. This means that all PCs that use the
correct SSID can log in.
ì Next to MAC address filter select the option On to activate the MAC filtering.
Entering MAC addresses manually
ì Enter the MAC address of the network adapter. You will find this address on the bot-
tom of the device.
ì Enter the name of the PC.
ì Click on 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 are displayed
that are currently logged in to the router with the correct SSID.
ì Click on the Add button to add the selected PC to the list.

Using UPnP (Universal Plug and Play)
PCs with UPnP (Universal Plug & Play) can offer their own network services and automatically use services offered on the network.
Please remember:
The PC must have Windows ME or Windows XP as its operating system. Check whether
the UPnP function has been installed in your PC's operating system. It may be necessar y to retrospectively install the UPnP components even on Windows XP or Windows
ME systems. Please consult your PC's operating instructions.
As soon as you have installed UPnP in the operating system of a PC and activated it on
the router, applications on this PC (e.g. Microsoft Messenger) can communicate via the
Internet without your needing to expressly authorise it. In this case, the router automatically implements port forwarding (Port Forwarding, see page 64), thereby facilitating
communication via the Internet.
You will see a symbol for your Gigaset SE551 WLAN dsl/cable on the task bar on the PC
on which UPnP is installed. Windows XP systems will also include the icon under network connections. Clicking on this icon opens the Gigaset SE551 WLAN dsl/cable's configuration screens.

Attack detection
If the firewall functions of your Gigaset SE551 WLAN dsl/cable are activated, the device
monitors and limits the access of incoming traffic via the DSL connection with a function called Stateful Packet Inspection (SPI). This allows the Gigaset SE551 WLAN dsl/
cable to identify and prevent certain types of attack from the Internet, such as Denialof-Service (DoS). DoS attacks are aimed at devices and networks with Internet connections. The aim is not so much to steal data but to paralyse the computer or network to
such an extent that the network resources are no longer available. A typical hacker
attack involves making a remote computer announce that it is acting for the paralysed
device, for example, and receive the data meant for it.
You can use the Attack Detection function to change the standard firewall settings and
arrange to be notified by email about any attempted hacker attacks.
ì In the Advanced Settings – Internet – Firewall menu, select Attack Detection.
ì Select the security level for the firewall.
The default setting is Medium, which combines a high degree of security with little
effect on functionality.

Setting up the NAT function
Your Gigaset SE551 WLAN dsl/cable comes provided with the NAT (Network Address
Translation) function. With Address Mapping, several users on your local network can
access the Internet via one or more public IP addresses. In the default setting, all the
local IP address are mapped to your router's public IP address.
One feature of NAT is that data from the Internet is not allowed into your local network
unless it has been explicitly requested by one of the PCs on that network. Most Internet
applications run behind the NAT firewall without any problems. If you request Internet
pages, for example, or send and receive e-mails, the request for data from the Internet
comes from a PC on the local network and so the router allows the data through. The
router opens exactly one port for the application. A port is an internal PC address
through which the data is exchanged between a server on the Internet and a client on
a PC in the local network. Communicating via a port follows the rules of a particular protocol (TCP or UDP).
If an external application tries to send a call to a PC within the local network, the router
will block it. There is no open port via which the data could enter the local network.
Some applications, such as games on the Internet, require several links, i.e. several ports
so that the players can communicate with each other. In addition, these applications
must also be permitted to send requests from other users on the Internet to the user on
the local network. These applications cannot work if Network Address Translation (NAT)
has been activated.
Using port forwarding (the forwarding of requests to particular ports) you make the
router forward requests from the Internet for a certain service, e.g a game, to the appropriate port or ports on the PC on which the game is running.
Port triggering is a specific variant of port forwarding. Unlike port forwarding, in this
case the Gigaset SE551 WLAN dsl/cable forwards data from the set port block to the PC
which has previously sent data to the Internet via a certain port (trigger port). This
means that approval for the data transfer is not tied to one specific PC in your network,
but only to the port numbers of the required Internet service.
Where configuration is concerned, this means:
u You have to define a so-called trigger port for the application and also the protocol
(TCP or UDP) that this port uses. Then you assign to this trigger port the public ports
that have to be opened for the application.
u The router checks all outgoing data for the port number and protocol. If it recognises
a match of port and protocol to a defined trigger port, then it will open the assigned
public ports and notes the IP address of the PC that sent the data. If data comes back
from the Internet via one of these public ports, it allows the data through and directs
it to the right PC. A trigger event always comes from a PC within the local network.
If a trigger port is addressed from outside, it is simply ignored by the router.
61
Page 62
Configuring the Advanced Settings
Please remember:
u An application that is configured for port triggering can only be run by one user in
the local network at a time.
u As long as the public ports are open, they can be used by unauthorised persons to
gain access to a PC in the local network.
When the Gigaset SE551 WLAN dsl/cable is supplied, the NAT funct io n ( Net wo rk Add re ss
Translation) is activated, i.e. all IP addresses of PCs in the local network are converted to
the router's public IP address when accessing the Internet.
You can use the NAT settings for the Gigaset SE551 WLAN dsl/cable to
u set up port triggering for special applications (see page 63),
u set up the Gigaset SE551 WLAN dsl/cable as a virtual server by configuring Port For-
warding (see page 64),
u open the firewall for selected PCs (see page 65).
Please remember:
For the functions described below you must make sure that the IP addresses of the
PCs do not change. If the IP addresses of the PCs are assigned via the DHCP server
of the Gigaset SE551 WLAN dsl/cable, you must select the option Never expires
(see page 70) for the settings on the Local Network screen for Lease time or assign
static IP addresses for the PCs.
You can activate or deactivate the NAT function (default setting: NAT function is activated).

Port Forwarding
If you configure Port Forwarding, the Gigaset SE551 WLAN dsl/cable outwardly assumes
the role of the servers. It receives requests from remote users under its public IP address
and automatically redirects them to local PCs. The private IP addresses of the servers on
the local network remain protected.
Internet services are addressed via defined port numbers. The Gigaset SE551 WLAN dsl/
cable needs a mapping table of the port numbers to redirect the service requests to the
server that actually provides the service. For this, Port Forwarding has to be configured.
ì To set up port forwarding for a service, select Port Forwarding in the
Address Translation (NAT) menu.
ì Select the required application from the Predefined applications list.
ì Click the Add button. The data for the required service is entered on the screen.
ì Select the option in the Enabled column.
If the application you require is not in the list, then you must enter the relevant data on
the screen manually:
ì Select the protocol of the service you are providing from the Protocol list.
ì Under Public port, enter the port number of the service you are providing.
ì In the Local port field, enter the internal port number to which service requests are
to be forwarded.

Configuring the Advanced Settings
ì In the Local IP address field, enter the IP address of the PC which provides the serv-
ice.
Example: the Web server has been configured to react to requests on port 8080.
However, the requests from websites enter by port 80 (standard value). If you add
the PC to the forwarding table and define port 80 as the public port and Port 8080
as an internal port, all requests from the Internet are diverted to the service with the
port number 80 on the Web server of the PC you have defined with port 8080.
Note:
You can enter a single port number, several individual port numbers separated by
commas, port blocks consisting of two port numbers separated by a dash, or any
combination of these, e.g. 80,90-140,180).

ì Click OK to apply the settings.
Opening the firewall for selected PCs (Exposed Host)
You can set up a client in your local network to be an exposed host. Your device will
them forward all incoming data traffic from the Internet to this client. You can then, for
example, operate your own Web server on one of the clients in your local network and
make it accessible to Internet users.
As the exposed host your local client is directly visible to the Internet and therefore particularly exposed to risk (e.g. from hacker attacks). You should only activate this function if it is absolutely necessary (e.g. to operate a Web server) and other functions
(e.g. port forwarding) are not adequate. In this case you should take appropriate measures on the clients concerned.
Please remember:
Only one PC per public IP address can be set up as Exposed Host (see also the section
"Port Forwarding" on page 64.
ì To set up a PC as Exposed Host, select Exposed Host in the Address Translation

Dynamic DNS
Any service you provide on the Internet can be accessed by Domain names. Your router's
Public IP address is assigned to this domain name. If your Internet Service Provider for
your local network's WAN connection assigns the IP address dynamically, the IP address
of the router can change. The assignment to the domain name will no longer be valid
and your service will no longer be available.
In this case you must ensure that the assignment of the IP address to the domain name
is regularly updated. This is handled by the dynamic DNS service (DynDNS). You can use
the DynDNS service to assign your Gigaset SE551 WLAN dsl/cable an individual static
domain name on the Internet even if it does not have a static IP address.
There are various providers on the Internet offering free DynDNS service.
The Gigaset SE551 WLAN dsl/cable uses the DynDNS service from DynDNS.org
(http://www.DynDNS.org)
service can be reached on the Internet as a subdomain of one of the DynDNS.org

QoS (Quality of Service)
Many communication and multimedia applications require high speed and large bandwidths to transfer data between the local network and the Internet. However, for many
applications there is often only one Internet connection with limited capacity available.
QoS (Quality of Service) divides this capacity between the different applications and
provides undelayed, continuous data transfer where data packets with higher priority
are given transmission preference.
ì In the Advanced Settings – Internet menu, select the entry QoS.
ì Activate Differentiated services, i.e. the prioritisation of certain services for data
transfer between your network and the Internet.
ì In the field next to Upstream rate, enter the value for your DSL connection. The

You can determ ine via Priority which data packets are to be given preferential transmission. With the aid of PHB (Per Hop Behaviours) a decision is also made about whether
data packets are to be forwarded immediately before all others (EF, Expedited Forward-
ing), guaranteed and without data loss (AF, Assured Forwarding) or normally (BE, Best
Effort). If your application already supports QoS your application will determine the priority automatically, and this will be noted by your device for forwarding. In addition,
your device recognises certain Predefined applications and gives each data packet the
relevant priority. You can also determine which proportion of the bandwidth for your
Internet connection is to be made available for a certain class as Allocated bandwidth.

Please remember:
New settings can only be made after rebooting the Gigaset SE551 WLAN dsl/cable.
If necessary, reconfigure the IP address on your PC (including one that is statically
assigned) so that it matches the new configuration.
Configuring the DHCP server
The Gigaset SE551 WLAN dsl/cable has a DHCP Server for which the factory setting is
active. As a result, the IP addresses of the PCs are automatically assigned by the
Gigaset SE551 WLAN dsl/cable.
Please remember:
u If the DHCP server for the Gigaset SE551 WLAN dsl/cable is activated, you can con-
figure the network setting on the PC so that the option Obtain an IP address
automatically is set. To find out how to do this, please read the document enti-
tled “Network configuration” on the CD.
u If you deactivate the DHCP server, you will have to assign a static IP address for
the PCs using the network settings.
ì To activate the DHCP server, select On.
ì If the DHCP server is active, you can define a Lease time. The Lease time determines
the period for which the PCs keep the IP address assigned to them without changing
them.

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 configuration 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 deactivated (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.
Please remember:
The connection to the wireless network adapters will be interrupted until you enter
the new SSID on them as well.
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.
Tra nsmission mo de
This function is only shown in the window if the Super G transmission mode is deactivated (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 environment of your local network. A much greater range makes it easier to eavesdrop
on your wireless data transmission.

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.
Please remember:
If you activate Super G as the transmission mode, but it is not supported by all components in your wireless network, then for technical reasons the transfer rate in the network may be significantly lower than the possible maximum of 108 Mbit/s.
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 netwo rk, alb eit at very lo w da ta t rans fer 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.

Setting wireless security
If you are sending data over wireless channels, we recommend that you activate encryption (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)
74
Page 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 wireless network. Every PC (network adapter) that requires access to a wireless network protected 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 support WPA2, select option WPA2-PSK. If you are using network adapters that only support 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.

Configuring the Advanced Settings
WPA and WPA2 with authentication server
In large networks (e.g. in companies) WPA enables the use of an additional authentication 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 standard WPA2 if this is supported by all components in your wireless
network, or select WPA2 / WPA if you are using devices that only support WPA.
ì Select the required option in the Security field.
ì Enter the IP address of the RADIUS server in the RADIUS server IP address field.
ì Enter the port of the RADIUS server in the RADIUS server port field.
ì In the RADIUS server secret key field, enter a keyword conforming to the conven-
tions of the RADIUS server, which is to be used by the server for authentication.
ì Click on OK to apply the settings.

activate WEP-Encryption on your wireless network components.
ì In the Security field, select the option WEP.
ì Select the Authentication type:
–Select Shared to require that each client logs in to the network with a specified
key.
–Select Open to permit data transfer within your wireless network without the
need for a key.
You can choose either the standard 64 bit key or the more robust 128 bit key for encryption. The keys are generated in hexadecimal or in ASCII format. You must use the same
keys for encryption and decryption for both the Gigaset SE551 WLAN dsl/cable and all
your wireless network adapters.
ì Select the Key length: 64 bit or 128 bit.
ì Select the Input type, i.e. whether you wish to enter the key manually or have it
