Introduction
Sandberg Wireless G54 Router (referred to as “the router”) allows you to share a broadband
connection and local area network connection using both wireless and wired connections. The
Sandberg Wireless G54 Router is easy to configure thanks to its user-friendly web interface. Its
features include a range of security settings that you can configure to prevent uninvited guests.
The router works with ADSL, xDSL and cable modem connections that support one of the three
protocols Ethernet, PPPoE or PPTP. Your Internet service provider can tell you whether your Internet
connection is using one of these three standards.
1 Installing the router
1.1 Role of the router on the network
A router acts as a connection point between two networks. A router is generally used to connect
a local area network with multiple computers to the network of an Internet service provider. In
other words, a router allows several computers to share an Internet connection. The Sandberg
Wireless G54 Router is wireless, meaning that computers with wireless network cards can connect
to it without the use of cables.
Figure 1 shows an example of a typical network setup, with two computers sharing an Internet
connection.

As the router’s role is to create a bridge between two networks, it has one IP address for each
network. One IP address represents the router on the Internet and is called the external IP address,
and the other represents the router on the local area network and is called the internal IP address.
Each of the computers on the local area network also has its own IP address. This can be allocated
automatically by the router (using the router’s DHCP function) or it can be specifi ed manually on
each computer.
Figure 2 shows a typical network setup, and the IP addresses that form part of that setup.
172.64.102.85 is the router’s external IP address. When communicating with a computer over the
Internet, it will be this address that the computer ‘sees’, regardless of which computer on the local
area network is being used. The external IP address can either be dynamic or fi xed, depending
on the type of subscription set up with the Internet service provider. A dynamic IP address is one
that is allocated by the Internet service provider, but it is not necessarily the same address all
the time. A fi xed IP address always remains the same.
192.168.16.1 is the router’s internal IP address. This is the address of the router on the local area
network, the one that all the computers on the network connect to in order to access the Internet.
192.168.16.100 is the IP address of a computer on the network. This can either be defi ned in
Windows or be automatically allocated by the router.
192.168.16.101 is the IP address of a computer on the network. This can either be defi ned in
Windows or be automatically allocated by the router.

1.2 Connecting the router
The router can function both as a router and an access point. The connection mode used with
the router depends on how it is intended to function on the network.
• Router – Used if the Internet connection is to be shared between multiple computers, either
wirelessly, with cables, or both.
• Access Point – Used if the Internet connection is already shared between multiple computers,
e.g. via a router, and wireless access to the Internet is required. In this case, the role of the router
is to provide wireless access to the existing router.
1. Connect the electrical plug to a mains socket and the small round connector on the power lead
to the POWER socket on the router. Check that the “Power” lamp lights up.
• If you will be using the router function, connect the router’s WAN port to your existing ADSL/
broadband connection using a network cable.
• If you will be using the access point function, connect a network cable from the existing
network (typically the existing router) to port 1, 2, 3 or 4 on the router.
2. Screw the supplied antenna firmly into the thread on the far left. The antenna can be folded
upwards to increase the signal strength.
3. Connect up to four computers to the ports marked 1 to 4 on the router. If you will only be
connecting wirelessly, skip this step.
4. Start the connected computers.

The default router configuration is now complete. However, before using the router, you should
secure it against unauthorised wireless access. Instructions for this are given in section 2.2
below.
2.2 Securing a wireless network
If you are using the router’s wireless functionality, the network must be secured against
unauthorised access by enabling one of the router’s built-in security features. This protects
authorised network users against unauthorised access from the outside.
The router can use one of the following security features:
• WEP
• WPA pre-shared key
• WPA RADIUS
All computers that connect wirelessly to the router must use the same type of security as the
router. It is therefore important to select a security method supported by all the network cards
on the network. For more information on this, see the user guide for the individual network
cards on the network.
6
For additional security, the Access Control function can be used. See section 2.3.4 for information
on this.
Confi guration of the various security features is described in the following sections.
2.2.1 Configuring WEP
1. Click [WLAN Setup].
2. Select the [Security] tab.
3. Under Encryption Method, select WEP.
4. Under Key Length, select the encryption strength. You can select either 64-bit or 128-bit. For
greatest security, 128-bit is recommended.
5. Under Key Format, select the format for entering security codes. You can select either HEX
(digits and/or letters from A to F) or ASCII (letters and/or digits).
6. Under Default TX Key, select the security code to use as default.
7. In the fields Encryption Key 1-4, enter up to four security codes. If you enter multiple codes,
computers can access the network wirelessly by entering any one of them. The codes must
comply with the format given in Key Length and Key Format. Both upper and lower case letters
can be used.
64-bit HEX - 26 digits and/or letters from A to F
128-bit HEX - 26 Ziffern und/oder Buchstaben von A bis F
64-bit ASCII - 5 letters and/or digits
128-bit ASCII - 13 letters and/or digits
8. Click [OK].
NB: Make a note of all the codes, as these must be entered on all the computers that connect
wirelessly to the router.
2.2.2 Configuring WPA/WPA2
1. Click [WLAN Setup].
2. Select the [Security] tab.
3. Under Security Mode, select WPA/WPA2/Mixed.
4. Under WPA Type, select the encryption method to use.
5. Under WPA/WPA2 Cipher Suite select the encryption type to use. The options are TKIP, AES
or TKIP/AES. Note that all devices connecting to the network must support the encryption type.
6. Under Pre-Shared Key Format, select the format for entering security codes.
7. Enter a code in the Pre-Shared Key field.
8. Click [OK].
2.2.3 Configuring RADIUS
This type of security is for advanced users and requires a separate RADIUS server. RADIUS is
typically used in larger corporate networks, and is not recommended for private use. Documentation
on configuring the router for RADIUS can be found in the English manual on the CD provided.

3.5 Services
3.5.1 Virtual Server
NAT (Network Address Translation) is a technology that allows multiple computers on a local
area network to share the same external IP address. The way this works is that the router manages
all the network traffic originating from the computers on the network and sorts incoming network
traffic so it is redirected to the right computer. However, this may cause a problem for network
traffic that is not initiated at the request of a computer on the local area network.
A typical scenario is when a computer on the local area network is set up as a server. In this case,
a computer on the Internet would connect to the router’s external IP address. However, this network
request does not indicate which computer on the local area network it is addressed to, and the
router therefore has no means of knowing where to forward it.
This is solved by setting up the router’s NAT function so that it forwards incoming network traffic
on certain network ports to a specific IP address on the local area network.
Example: An FTP server is set up on a computer on the network with the IP address 192.168.16.100.
FTP uses network port 21 by default.
The router’s NAT function is set up to forward all incoming traffic on port 21 to IP address
192.168.16.100.
It may also be necessary to configure NAT for applications such as IP telephony, file sharing and
online gaming to work properly.
NB: For Virtual Server to work as intended, the computer that network traffic is forwarded to must
be configured with a static IP address.
1. Click [New…].
2. Under Type, enter the types of service to grant access to, e.g. FTP.
3. Under Service Name, enter a name of your choice.
4. Under Forward Port, enter the numbers of the relevant inbound ports.
5. Under Local Port, enter the numbers of the local ports.
6. Under Local Server IP, enter the IP address of the computer providing the desired service.
7. Click [OK]. Any new services can then be set up in the same way.

4 Troubleshooting
I cannot connect to the router when I type http://192.168.16.1 in my browser.
• Check that the originating computer is connected to the router’s wireless network. See section .
• PCheck that the originating computer is configured to be automatically allocated an IP address.
This can be checked in the network adapter setup under Control Panel in Windows.
• If necessary, try connecting the computer directly to port 1 on the router using a network cable.
The router cannot be detected by any wireless devices in the vicinity.
• Check that the “Wireless” LED on the router is on.
• Check that the router is within range of the wireless devices. Try repositioning the router or the
wireless device trying to connect to it. The number of walls and ceilings, and their thickness and
materials, are all factors that affect the strength of the wireless signal.
• Check that the wireless devices are connected to the correct wireless network. See the documentation
for the wireless devices for information on this.
Unable to connect to the router from a wireless device.
• Check that the security settings are appropriate for the wireless devices trying to connect to the
router. See section and the documentation for the wireless device for information on security
settings.
The router is connected to my Internet equipment but cannot access the web.
• Check that the Internet equipment is correctly connected (see section 1.2). For further information
about your Internet equipment, contact your Internet service provider.
• In certain configurations, the connected computers must have their IP addresses allocated by
the Internet equipment. If this is the case, disable the router’s built-in DHCP server (see section
2.1.2).
• Check that the correct connection type is selected (see section 2.1.1) and that the details entered
are correct.

Introduktion
Sandberg Wireless G54 Router (herefter kaldet ”routeren”) giver dig mulighed for at dele en
bredbåndsforbindelse og lokal netværksforbindelse både ved trådløst og kablet tilslutning. Sandberg
Wireless G54 Router konfigureres nemt ved hjælp af et brugervenligt web interface. Her har du
bl.a. mulighed for at opsætte en række sikkerhedsindstillinger, så du undgår ubudne gæster.
Routeren virker med ADSL, xDSL, og kabelmodem forbindelse, der understøtter en af de ftre
protokoller Ethernet, PPPoE eller PPTP. Din internetudbyder kan oplyse dig om, hvorvidt din
internetforbindelse benytter én af disse tre standarder.
1 Installation af Routeren
1.1 Routerens rolle i netværket
En router fungerer som forbindingspunkt mellem to netværk. Oftest anvendes routeren til at
forbinde et lokalnetværk med et antal computere til internetudbyderens netværk. Med andre ord
tillader en router, at flere computere deler den samme internetforbindelse. Sandberg Wireless
G54 Router er trådløs, så computere med trådløst netkort kan forbinde til den uden kabler.
viser et eksempel på en typisk netværksopstilling, hvor to computere deler en internetforbindelse.

DSL eller
Kabelmodem

Da routerens rolle er at danne bro mellem to netværk, har den en IP adresse på hvert netværk.
Én IP adresse der repræsenterer routeren på Internettet, kaldet den eksterne IP adresse, og én
der repræsenterer den på lokalnetværket, kaldet den interne IP adresse. Computere på lokalnetværket
har tillige en IP adresse hver. Denne kan tildeles automatisk fra routeren (ved hjælp af routerens
DHCP funktion), eller den kan indstilles på hver computer.
illustrerer en typisk netværksopsætning, og de IP adresser der indgår i opstillingen.
172.64.102.85 er routerens eksterne IP adresse. Når der kommunikeres med en computer på
Internettet, vil det være denne adresse, computeren ”kan se” – uanset hvilken computer i
lokalnetværket, der anvendes. Den eksterne IP adresse kan være enten dynamisk eller fast, alt
efter hvordan internetabonnementet er sat op hos udbyderen. En dynamisk IP adresse tildeles
af internetudbyderen, men er ikke nødvendigvis den samme adresse altid. En fast IP adresse er
altid den samme adresse.
192.168.16.1 er routerens interne IP adresse. Det er den adresse, routeren har på det lokale
netværk, og som alle computere i netværket forbinder til for at komme på Internettet.
192.168.16.100 er IP adressen på en computer i netværket. Denne kan enten være defineret i
Windows, eller være automatisk tildelt af routeren.
192.168.16.101 er IP adressen på en computer i netværket. Denne kan enten være defineret i
Windows, eller være automatisk tildelt af routeren.

1.2 Tilslutning af routeren
Routeren kan både fungere som router og access point. Måden routeren tilsluttes på, afhænger
af hvordan den skal fungere i netværket.
• Router – Anvendes hvis internetforbindelsen skal deles mellem flere computere, enten trådløst,
med kabler eller begge dele.
• Access Point – Anvendes hvis internetforbindelsen allerede er delt mellem flere computere, f.eks.
via en router, og der ønskes trådløs adgang til internettet. Her er routerens rolle, at sørge for
den eksisterende router kan tilgås trådløst.
1. Tilslut strømforsyningens strømstik til en stikkontakt og strømforsyningens lille runde stik til
stikket POWER på routeren. Kontrollér at ”Power” lampen lyser.
• Skal routerfunktionen anvendes, tilsluttes routerens WAN port til din eksisterende
ADSL/bredbåndsforbindelse med et netværkskabel.
• Skal access point funktionen anvendes, tilsluttes et netværkskabel fra det eksisterende netværk
(typisk den eksisterende router) til port 1, 2, 3 eller 4 på routeren.
2. Skru den medfølgende antenne fast i gevindet yderst til venstre. Antennen kan bukkes opad
for forøgelse af signalstyrken.
3. Tilslut op til fire computere til portene mærket 1-4 på routeren. Ønskes det kun at bruge trådløs
forbindelse, springes dette trin over.
4. Start de tilsluttede computere.

Routerens standardopsætning er nu konfigureret. Før den tages i brug, bør den dog sikres mod
uønsket trådløs adgang. Information herom findes i afsnit 2.2 herefter.
2.2 Sikring af trådløst netværk
Anvendes routerens trådløse egenskaber, bør netværket sikres mod uønsket adgang ved at
aktivere en af routerens indbyggede sikkerhedsfaciliteter. Hermed sikres godkendte brugere af
netværket imod uautoriseret adgang udefra.
Routeren kan anvende en af følgende sikkerhedsfaciliteter:
• WEP
• WPA/WPA2
• WPA RADIUS
Alle computere der forbinder trådløst til routeren skal anvende samme type sikkerhed som
routeren. Derfor er det vigtigt at vælge en sikkerhedsmetode, som samtlige netkort i netværket
understøtter. Se nærmere information herom i brugsanvisningen til de enkelte trådløse netkort
i netværket.
