Never let liquids get inside the FRITZ!Box. Otherwise,
electric shocks or short circuits may result.
The FRITZ!Box is intended for indoor use only.
Do not open the FRITZ!Box housing. The device con-
tains hazardous components and should only be
opened by authorized repair technicians.
Handling the
FRITZ!Box
You can either place FRITZ!Box on a horizontal surface or
mount it on a wall. Please note the following:
Place or hang the FRITZ!Box in a dry location that is
free of dust and protected from direct sunlight.
Do not place the FRITZ!Box on excessively heat-sensi-
tive surfaces, as the base of the device can heat up
during normal operation.

FRITZ!Box.
1. Insert the FRITZ!Box CD in the CD-ROM drive of your
computer.
The Installation Help starts automatically.
2. Follow the instructions in the Installation Help to pre-
pare the FRITZ!Box for operation.
At the conclusion of the Installation Help, you will be rout-
ed directly to the FRITZ!Box user interface.
Please see the instructions about setting up the
FRITZ!Box in section “Security and Handling” on page 7.
We recommend using the Installation Help on the
FRITZ!Box CD when launching operation of the FRITZ!Box
for the first time.

Connecting to the computer
Connecting Set aside the power supply unit out of the FRITZ!Box
package.
1. Connect the power supply unit to the socket on the
FRITZ!Box labeled “Power”.
2. Plug the other end into an AC power outlet.
The green “Power/DSL” LED will light up after a few sec-
onds to indicate that the device is ready for operation.
3.3 Connecting to the computer
If you would like to surf the web using the FRITZ!Box or to
open the FRITZ!Box user interface, then you must connect
a computer with the FRITZ!Box.
A computer can be connected with the FRITZ!Box in two
different ways:
via a LAN port
wirelessly via WLAN
Properties Note the following when connecting computers to the
FRITZ!Box:
One computer can be connected to the FRITZ!Box by
only one of these means.
At each of the network ports of the FRITZ!Box, a com-
puter can be connected directly or via a hub/switch.
Using WLAN you can connect multiple computers wi-
th the FRITZ!Box at the same time.
The way a computer is connected to the FRITZ!Box is
the same regardless of the operating system on the
computer.
All of the computers connected with the FRITZ!Box
constitute a network.

Connecting Computers to the LAN Port
FRITZ!Box Fon WLAN 7113 15
3.4 Connecting Computers to the LAN Port
If you would like to connect a computer to the LAN port of
the FRITZ!Box, make sure the computer is equipped with a
LAN port (network adapter). A LAN port is usually desig-
nated by the icon at left or labeled “LAN”.
Connecting a computer to a LAN port on the FRITZ!Box
Connecting Set aside the network cable (red) from the FRITZ!Box pack-
age.
1. Switch on your computer.
2. If you work with a Linux operating system, use YaST
to configure your network card with the setting
“DHCP”, if this setting is not already configured.
3. Insert one end of the LAN cable to the computer’s
network adapter.
4. Connect the other end of the network cable to one of
the sockets on FRITZ!Box labeled ”LAN”.
Now the FRITZ!Box and computer are connected to each
other.

You can connect a network hub or switch to the LAN port if
you would like to connect multiple computers to the
FRITZ!Box via LAN.
Connecting FRITZ!Box to a network hub
Connecting Set aside the network cable (red) from the FRITZ!Box
package.
1. Connect one end of the LAN cable to the uplink port
of the network hub or switch.
2. Connect the other end of the cable to the socket on
the FRITZ!Box labeled LAN.
The FRITZ!Box and network hub are now connected with
each other.

Connecting computer(s) wirelessly via WLAN
FRITZ!Box Fon WLAN 7113 17
3.5 Connecting computer(s) wirelessly via WLAN
Using WLAN you can connect one or multiple computers
with the FRITZ!Box wirelessly.
The wireless WLAN connection is independent of the operat-
ing system used. Each computer to be connected to the
FRITZ!Box via WLAN must support WLAN, by means of a com-
patible WLAN adapter, for instance the FRITZ!WLAN USB
Stick.
Presettings in the FRITZ!Box
The FRITZ!Box is delivered with preset values for WLAN se-
curity. These values must also be entered on the computer
with the WLAN adapter in order to be able to establish a
successful WLAN connection.
The following values are configured in the FRITZ!Box facto-
ry settings:
For more information on WLAN, see the section “More
about WLAN” from page 77.

Connect Using a WLAN Adapter
Connect Using a WLAN Adapter
You can connect computers with the FRITZ!Box wirelessly
as soon as you have installed a WLAN adapter and config-
ured WLAN software.
Installing 1. Switch on your computer.
2. Install a WLAN adapter, for instance the FRITZ!WLAN
USB Stick, on your computer along with the appropri-
ate software. Please take note of the instructions in
the documentation of the adapter.
Once installation has been completed, you generally have
software available to control your WLAN connections. In
the Windows operating systems you can open the user in-
terface of the WLAN software by clicking an icon in the
taskbar (specific to each manufacturer) or from the start
menu.
Alternatively, you can use the WLAN software supplied wi-
th the operating system to establish a WLAN connection to
the FRITZ!Box.
Establishing a
connection This description uses the values given in the section
“Presettings in the FRITZ!Box” on page 17.
If you would like to establish a WLAN connection using
these preset values, then your WLAN adapter must support
the WPA encryption procedure.
1. Start the WLAN software.
2. Select the SSID (WLAN radio network) “FRITZ!Box Fon
WLAN 7113” in the user interface.
If the radio network is not displayed, follow the
instructions in the section “The WLAN Adapter
Cannot Find FRITZ!Box” from page 59.
3. Set “Infrastructure” as the network mode.
4. Select “WPA PSK” as encryption or authentication.
5. Enter the preset key in the “Network Key” field. The
key is printed on the sticker on the base of your
FRITZ!Box.

WLAN adapter
does not support
WPA
If your WLAN adapter does not support the WPA security
mechanism, you must change the WLAN settings in the
FRITZ!Box to WEP.
Proceed as follows to change the encryption method:
1. Connect the FRITZ!Box and the computer using the
network cable (see the section “Connecting Comput-
ers to the LAN Port” from page 15).
2. Start a web browser.
3. Enter fritz.box in the address field.
The FRITZ!Box user interface opens.
From today’s perspective, WEP encryption does not offer
adequate protection. Contact the manufacturer of your
WLAN adapter for an update that makes the adapter able
to support WPA. We strongly advise against using WEP for
encryption in the long term!
