Introduction
Local networks with Gigaset products
You can use Siemens Gigaset WLAN devices to set up a local network, e.g. a home network. All the PCs in this network can communicate with each other and have access to
the Internet. The PCs can run on Windows 98, Windows ME, Windows 2000 or Windows
XP. Gigaset Routers e.g. the Gigaset SE551/WLAN dsl/cable have an interface to enable
Internet access, so that you can connect a DSL or cable modem for Internet access (WAN
interface).

You can set up the network in a number of ways. You can
u Use a Gigaset SE551 WLAN dsl/cable to set up a wired local network (see page 5).
u Use the Gigaset SE551 WLAN dsl/cable to set up a local network comprising wireless
and wired network components (see page 8).
u Use the wireless network adapters Gigaset PC Card 108, a Gigaset USB Adapter 108
or a Gigaset USB Stick 108 to set up a wireless network without routers, i.e. connect
PCs directly with each other (see page 6), or connect PCs to a Gigaset SE551 WLAN
dsl/cable (see page 7).
u Use one or more Gigaset WLAN Repeaters to extend the range of your wireless local
network (see page 10).

Introduction
Wired local network (Ethernet)
In a wired local network the PCs are linked via an Ethernet cable. The Siemens Gigaset
SE551 WLAN dsl/cable has four Ethernet LAN ports for connecting four PCs. The PCs
must have an Ethernet network adapter that is connected via an Ethernet cable to a LAN
port on the router. New PCs frequently come supplied with such a socket. You can buy
Ethernet cables (CAT-5) from specialist retailers.
Internet
Ethernet
The WAN interface on the Gigaset SE551 WLAN dsl/cable allows all PCs in the network
to access the Internet simultaneously. To use this feature you will need the access data
from an Internet Service Provider, e. g. T-Online.

Introduction
Wireless local network (WLAN)
In a wireless local network (WLAN), the PCs are linked to each other via a wireless connection. The PCs must be equipped with a wireless network adapter (e.g. the Gigaset PC
Card 108 or Gigaset USB Adapter).
We generally differentiate between two types of wireless networks:
u ad-hoc mode
u infrastructure mode
Ad-hoc network
Ad-hoc networking is a new concept in network communications that is rapidly gaining
in popularity. Ad-hoc networks do not have any fixed network infrastructure. 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 on 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.
An ad-hoc network is a wireless network set up without using a router.

Introduction
Infrastructure Network
The infrastructure mode is used to connect wireless and wired networks with each
other. In addition to the mobile stations, the infrastructure mode needs an access point,
also known as a base station. In infrastructure mode, the stations on the network always
communicate with each other via an access point. Unlike the ad-hoc mode, the access
point sets up the wireless network on a permanent basis, and every station that wants
to be part of the wireless network has to register with the access point before it is
allowed to exchange data. Using an access point also extends the range of the wireless
network.
The access point establishes the connection from the mobile stations of a wireless network to a wired LAN (Ethernet) or to the Internet. In this case, this is referred to the
router functionality of the device. The access point sends data packets that are not
addressed to stations in its network "outside" and passes data packets coming from "outside" to the appropriate station in its network.
The Gigaset SE551 WLAN dsl/cable is such an access point. You can use it for connecting
u wireless linked PCs to the Internet and
u connect PCs with a wireless connection to a wired network.
Infrastructure mode is the standard configuration for the Gigaset SE551 WLAN dsl/
cable. This configuration is described in the quick guide enclosed with the router.
Connecting wireless networks to the Internet
The Gigaset SE551 WLAN dsl/cable has a WAN interface that permits simultaneous
access of all the stations to the Internet. To use this feature, you will need a DSL or cable
connection from an Internet Service Provider. Please check whether your Internet Service Provider supports parallel access by several PCs.

Introduction
Linking a wireless network (WLAN) to a wired network (LAN)
A major advantage of wireless networks is their ability to work easily with existing wired
networks. You can set up a wireless network to link mobile stations with an existing
wired network. This requires all the stations in the wireless network to work 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. These PCs also access the Internet via
the Gigaset SE551 WLAN dsl/cable.
Please note:
You can also connect an Ethernet router to a LAN port, providing access to a larger
wired network. If you want to connect the Gigaset network to an existing network, a
variety of settings need to be taken into account. Therefore we cannot provide a general example for this use; the configuration depends greatly on the networks in question. We advise having configuration of such a network carried out by an expert.

Introduction
Extending a wireless network using a repeater
You can use a repeater, e.g. the Gigaset WLAN Repeater 108 to extend the coverage of
your wireless network. To do this, set it up at the limit of the range of your wireless network. The Gigaset WLAN 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 would be possible with the Gigaset SE551 WLAN dsl/cable alone.

Introduction
Roaming
In a wireless network with several repeaters, roaming allows the connected subscribers
(PCs) to move freely between the different repeaters without breaking their contact
with the access point. As soon as there is a risk of losing contact, the PC automatically
searches for another repeater with a stronger signal. This allows you to set up wireless
networks that cover a much larger area than would be possible with just a single access
point (and a single additional repeater). Multiple repeaters also allow more subscribers
to be served simultaneously. The main area of application for WLANs with roaming is on
large company sites and in universities.

In a roaming network, all the users must use the same SSID and encryption. The access
point must be connected to a wired network (Ethernet). For details, refer to the operating instructions on the CD supplied.

Introduction
Possible uses
No matter which type of network you have opted for, Gigaset products for local networks offer a wealth of uses.
u Shared use of files
You can use your Gigaset SE551 WLAN dsl/cable or a PC in the network as a file
server.
All central data are then
– stored in a bulk memory connected directly to the USB interface on your Gigaset
SE551 WLAN dsl/cable
– or in the data system of a PC in the network.
Users on other PCs can hook up folders or entire drives on this file server to their own
PCs and work with them as if they were actually on their local PC. Various access
rights can be assigned.
How to connect a bulk memory to the Gigaset SE551 WLAN dsl/cable and use it in
the network is described in the device's user guide.
How to release files on one PC for access to users on other PCs is described in Chapter
"Releasing files and printers for shared use":
– for Windows XP from page 21
– for Windows 2000 from page 32
– for Windows 98, 98 SE, ME from page 46
How to make released files on other PCs available on your PC is described in Chapter
"Using released files and printers":
– for Windows XP from page 53
– for Windows 2000 from page 58
– for Windows 98, 98 SE, ME from page 66
u Shared use of printers
Printers can be made available to PCs in the network in two ways:
– directly via the USB interface on your Gigaset SE551 WLAN dsl/cable
– via the PC on the network to which the printer is connected
All users can print their files at these printers.
Being directly connected to the Gigaset SE551 WLAN dsl/cable offers the advantage
that the printer is always available without having to ensure that a specific PC is
switched on. How to connect a printer to the Gigaset SE551 WLAN dsl/cable and use
it in the network is described in the device's user guide.
How to release a printer on one PC is described in Chapter "Releasing files and printers for shared use":

u Controlled access to the Internet
You want to prevent users accessing particular Internet services or children having
access to any Internet pages at all. With the Gigaset Routers you can
– completely isolate PCs from the Internet.
– restrict access to Internet services,
– prevent access to particular web domains or Internet sites.
u Protecting local networks from unauthorised access
To protect your network from unauthorised access, you can for example
– set up access control for wireless users,
– set data encryption (only on wireless networks).
u Running games, conferences and telephony via the Internet
The Gigaset SE551 WLAN dsl/cable comes programmed with a comprehensive firewall functionality that protects your local network against unauthorized access from
the Internet. Some applications however, such as games, video conferences, Internet telephony etc., require the possibility of external access from the Internet to local
applications. The normal configuration of the router does not permit "external"
access and supports only those Internet applications that do not need more than
one connection (e.g. file transfer, email ...).
u Making your own server available on the Internet
Advanced Internet users might like to set up a Web server of their own so that they
can have their own home page or other offerings on the Internet. This requires a particular configuration for the Gigaset SE551 WLAN dsl/cable.
You will find information regarding the configuration of the four above-named functions of your Gigaset SE551 WLAN dsl/cable in the device's user guide.

Releasing files and printers for shared use
Releasing files and printers for shared use
A very common function of local networks is to allow the shared use of files and printers. Users can access from any PC on the network those files made available by another
PC on that network, or they can print their fi les v ia a printer administered on another PC.
File
Server
This chapter describes what steps you must carry out to release files and printers for network usage. It assumes that the network cards or wireless network adapters have
already been installed in the PCs and that the PCs are either connected via a router or
directly via an ad-hoc network.
The following steps are necessary before files and printers can be shared on the network:
u The network has to be set up on all the computers. The Internet protocol (TCP/IP) has
to have been set as the connection method.
u All PCs have to have been assigned to the same network (workgroup).
u Users who want to make their files or printer available have to release them on
their PC.
u After that, users who want to use other users' files or printers can make them avail-
able on their PC. This is described in Chapter "Using released files and printers" from
page 49.
13
Releasing files and printers for shared use
Network configuration, release and use differ depending on the Windows operating
system used.
Please note:
If you are using Windows 2000 on your network, you have to set up for all users who
are to have access to resources on a Windows 2000 PC the appropriate user IDs on the
Windows 2000 PC and their own PCs.
