The Gigaset SE551 WLAN dsl/cable
Your Siemens Gigaset SE551 WLAN dsl/cable is a powerful but easily operated device for
connecting your PC (WLAN) or your local network (LAN) to the Internet without the
need for wires (via a DSL or cable modem).
You can connect your PC wirelessly to the Gigaset SE551 WLAN dsl/cable and create a
wireless local network (WLAN). Thanks to Super G technology the transfer rate within
the local wireless network achieves up to 108 Mbps. For network security, wireless
transmission can be encrypted using the WPA standard or 64/128-bit WEP.
The Gigaset SE551 WLAN dsl/cable allows several users to access the Internet simultaneously. A single user account can be shared if your Internet Provider permits this.
If you want to surf the Internet at the lowest possible cost, then the Gigaset SE551
WLAN dsl/cable is a convenient and effective solution.
You can connect a DSL or cable modem to the WAN interface of your Gigaset SE551
WLAN dsl/cable.

There are various ways in which you can set up the network with a Gigaset SE551 WLAN
dsl/cable. You can
u set up a wired local network (Ethernet) and allow the connected PCs access to the
Internet (see page 8).
u set up a wireless local network (WLAN) and allow the connected PCs access to the
Internet (see page 9).
u set up a local network comprising wireless and wired network components (see
page 11).

Wired local network (Ethernet)
In a wired local network, PCs communicate with one another via an Ethernet cable.
When the Siemens 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.

The Gigaset SE551 WLAN dsl/cable
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.

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 19).
20
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.
21
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 20). 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
