Wireless local area network (WLAN)
In a wireless local area network (WLAN) PCs are linked without wires or cables. The PCs
have to be equipped with a wireless local area network adapter (WLAN adapter), for
example a Gigaset PC Card 108.
We generally differentiate between two types of wireless network:
uInfrastructure mode
uAd-hoc mode
Infrastructure mode
Infrastructure mode connects wireless and wired networks with one another. In addi-
tion to the mobile stations, infrastructure mode needs an access point such as the
Gigaset SE555 WLAN dsl. In infrastructure mode, the stations in the network always
communicate via this access point. The access point sets up the wireless network on a
permanent basis. Each station that wants to be part of the wireless network must first
register with the access point before it can exchange data. The range of the wireless net-
work can be increased by using an access point.
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 sta-
tions within the network "outside" and forwards data packets originating from "outside"
to the appropriate station within the network.
You can use the Gigaset SE555 WLAN dsl to connect
uwirelessly networked PCs to the Internet and
uwirelessly networked PCs to an Ethernet network.
Infrastructure mode is the default configuration for the Gigaset SE555 WLAN dsl. This
configuration is described in the quick guide enclosed with the router.
Ad-hoc mode
An ad-hoc network is a wireless network that has been configured without an access
point or a router. The mobile network components that communicate with each other
directly and wirelessly form the network on an "ad-hoc" basis, i.e. as and when required.
All the stations in the network have the same rights. Ad-hoc networks are used wher-
ever communications networks have to be set up quickly and there is no existing net-
work infrastructure, and where the participants are on the move.

Linking wireless networks with the Internet
The Gigaset SE555 WLAN dsl has an ADSL interface that permits all stations within its
local area network to access the Internet simultaneously. To be able to use this function-
ality you need a DSL connection obtainable from an Internet service provider. Find out
whether your service provider supports parallel access by several PCs.

Linking a wireless local area network (WLAN) to an Ethernet (LAN)
Wireless local area 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 local area network in infrastructure mode.
The Gigaset SE555 WLAN dsl 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 SE555 WLAN dsl.
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.

Extending the wireless network coverage with a repeater
Using a repeater, for example the Gigaset WLAN Repeater, you can extend your wireless
network's coverage. Set it up within the range of your network. The repeater will now
transmit data traffic into its own wireless area. This technology allows you to set up
wireless networks that cover a much larger area than is possible with a single Gigaset
SE555 WLAN dsl.
PCs to be connected in a wireless local area network via a repeater must be equipped
with a wireless network adapter or a USB adapter.

Features and applications
The Gigaset SE555 WLAN dsl's wide range of features makes it ideal for a large number
of applications, such as:
uInternet access
The Gigaset SE555 WLAN dsl allows several users to have Internet access via the
integrated ADSL modem.
– Since many DSL providers permit communication with end users via the PPPoE
protocol, the Gigaset SE555 WLAN dsl has an integrated Client for this protocol,
so you no longer have to install this service on your PC.
– If your Internet service provider permits this, the Gigaset SE555 WLAN dsl sup-
ports shared Internet access for up to 252 users. This means several users in your
network can surf the Internet at the same time, all using the same Internet
account.
uSetting up a local area network
The Gigaset SE555 WLAN dsl offers the following possibilities:
– Four devices connected via Ethernet ports with a transmission speed of 10 or
100 Mbps (with automatic recognition).
– Up to 252 mobile terminals connected via a radio interface with a transmission
speed of up to 108 Mbps. It complies with IEEE 802.11g standard and can work
with all products that satisfy Standard IEEE 802.11b or 802.11g. The Super G
technology allows for high transmission speed.
– Using a Gigaset SE555 WLAN dsl makes it easy to set up a network at home or in
small offices. For example, users can exchange data or share resources in the net-
work, such as a file server or printer. You can connect a USB hard disk or a printer
to the USB interface of the Gigaset SE555 WLAN dsl and make them available to
all users in your network.
The Gigaset SE555 WLAN dsl supports DHCP for dynamic IP configuration of the
local area network, and DNS for domain name mapping.

uSecurity functions
The Gigaset SE555 WLAN dsl offers comprehensive security measures:
–Firewall protection against unauthorised access from the Internet
All PCs in the local area network use the Public IP address of the Gigaset SE555
WLAN dsl for their Internet connections, which makes them 'invisible' on the
Internet. The Gigaset SE555 WLAN dsl only allows access from the Internet if it
has been requested from the local area network.
With the firewall the Gigaset SE555 WLAN dsl also offers comprehensive protec-
tion against hacker attacks.
– Service filtering and URL blocking
The Gigaset SE555 WLAN dsl can filter Internet access. Here you determine which
PCs may access which Internet services.
In addition, you can deactivate access to certain Internet domains and sites
(URL blocking).
– Access control and encryption for the local area network
You can use various encryption methods and authentication methods (WEP, WPA/
WPA2, 802.1x MAC access control) to prevent unauthorised access to your wire-
less LAN or make data illegible to unauthorised parties.
uOffering your own services on the Internet
– If you want to offer your own services on the Internet, you can set up the Gigaset
SE555 WLAN dsl as a virtual server without permitting further access to the local
area network.
–Static IP address
This allows you to release a PC in your local area network for unlimited access
from the Internet. Please note that in this case your local area network will no
longer be adequately protected against Internet attacks.
– You can use the Gigaset SE555 WLAN dsl to easily set up an FTP server and/or
HTTP server for access from the Internet.

guidelines:
uOperate the Gigaset SE555 WLAN dsl only indoors within a temperature range of
+5 to +40 °C. Do not position the Gigaset SE555 WLAN dsl near sources of heat. Do
not cover the ventilation slots. High temperatures can damage the device.
uA mains socket for 220/230 V~ and a connection socket for the splitter or LAN must
be available in the place where you set up the Gigaset SE555 WLAN dsl.
uDo not position the device in the immediate vicinity of stereo equipment, TV sets or
microwave ovens. This may cause interference.
uPosition the Gigaset SE555 WLAN dsl so that it is as near to the centre of your wire-
less network as possible. The general rule is: the higher you place the antennae, the
better the performance. Make sure that the place where you position the Gigaset
SE555 WLAN dsl offers optimum reception throughout the house or office.
uPosition the Gigaset SE555 WLAN dsl on a non-slip surface. The router feet do not
normally leave any traces on the surface they are on. However, some furniture sur-
faces may contain substances that attack and soften the router's rubber feet. The
feet may well mark the furniture surface in this case.
uPosition the Gigaset SE555 WLAN dsl so that it cannot fall down and damage the
antenna.
