1 Security and Handling
What to watch out for
Security When working with the FRITZ!Box Fon WLAN 7270, observe
the following security instructions in order to protect your-
self and the FRITZ!Box from harm.
Do not install the FRITZ!Box during an electrical storm.
Disconnect FRITZ!Box from the power supply during
electrical storms.
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 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 FRITZ!Box on excessively heat-sensitive
surfaces, as the base of the device can heat up during
normal operation.
When connecting to your FRITZ!Box computer using
the network, remember to take the length of the cable
into account.
If you would like to establish wireless connections be-
tween FRITZ!Box and the computer, position the de-

2 FRITZ!Box Fon WLAN 7270
An Overview
The FRITZ!Box Fon WLAN 7270 is a Private Branch Exchange (PBX) for
making telephone calls via the Internet and the fixed-line network.
The FRITZ!Box connects your computers directly with your DSL line. Each
connected computer can establish an Internet connection over the
FRITZ!Box. As a WLAN access point, FRITZ!Box offers you the possibility of
connecting your computer to the DSL line wirelessly.
Possibilities for connecting FRITZ!Box
PBX FRITZ!Box is a PBX for the connection of analog and ISDN
terminal devices. You can connect two analog telephones
to FRITZ!Box. Up to eight ISDN telephony devices can be
connected to the integrated ISDN S0port. You can make
telephone calls using the Internet, ISDN, or the analog
fixed-line network using all of the connected telephones.
Using Cordless
Phones Thanks to the DECT function, the FRITZ!Box can be used as
a basis station for cordless phones. Every cordless phone
that supports the DECT-GAP standard can be registered at
the FRITZ!Box.

FRITZ!Box Fon WLAN 7270 10
FRITZ!Box Fon WLAN 7270
Connecting
Computers Four computers can be connected directly to the FRITZ!Box
using the four LAN ports.
You can also connect a network hub or switch to the LAN
ports so that even more computers can be connected to
FRITZ!Box.
WLAN Access
Point The FRITZ!Box is a WLAN access point. All computers
equipped with a WLAN adapter can be wirelessly connected
to the FRITZ!Box.
Local Network All of the computers connected with the FRITZ!Box consti-
tute a network and can share access to any files released
for file sharing.
Internet All of the computers connected to the FRITZ!Box can access
the Internet.
The FRITZ!Box works as a DSL router, making the Internet
connection available to all connected computers. All con-
nected computers can then use the Internet connection at
the same time.
Firewall When the FRITZ!Box is operated as a DSL router configured
with the factory settings, the integrated firewall protects
your network from attacks from the Internet.
USB Port The FRITZ!Box is equipped with a USB host controller to
which you can connect a USB storage device (hard drive,
stick), a printer, an AVM FRITZ!WLAN USB Stick N, an AVM
FRITZ!WLAN USB Stick or a USB hub.
The USB port supports the USB 1.1 and USB 2.0 standards.
If you use AVM’s FRITZ!WLAN USB Stick N or the
FRITZ!WLAN USB Stick, AVM Stick & Surf technology is at
your disposal. Use Stick & Surf to adopt the WLAN security
settings from the FRITZ!Box quickly and conveniently.
For connecting a printer, FRITZ!Box has a printer server.
Media Server An integrated media server makes music files available in
the local network. Music files from a USB stick can be made
available even when the computer is switched off.
Network Devices Other network devices can also be connected to the net-
work ports of the FRITZ!Box, for instance game consoles.

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 with
the FRITZ!Box at the same time.
The computer is connected to the FRITZ!Box in the
same way regardless of the operating system on the
computer.
All of the computers connected with the FRITZ!Box
constitute a network.
3.4 Connecting Computer(s) to the LAN Port
If you want to connect a computer to one of the four LAN
ports on the FRITZ!Box, make sure that your computer is
equipped with a network adapter. A LAN port is usually des-
ignated by the icon at left or labeled “LAN”.

Connecting Set aside the network cable (yellow) from the FRITZ!Box
package.
1. Switch on your computer.
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.
2. Insert one end of the LAN cable to the computer’s net-
work adapter.
3. Connect the other end of the LAN cable to a socket on
the FRITZ!Box labeled “LAN 1”, “LAN 2”, “LAN 3” or
“LAN 4”.
Now the FRITZ!Box and computer are connected to each
other.
Connecting More Computers to the LAN Ports
Additional cables are required to connect further comput-
ers. In purchasing a LAN cable, note the instructions in the
section “Network Cable” on page 117.
You can connect a computer to any of the four LAN ports of
the FRITZ!Box at any time.
Connecting a Network Hub or Switch
You can connect a network hub or switch to one of the LAN
ports on the FRITZ!Box if you would like to connect multiple
computers to the via LAN.

Connecting FRITZ!Box to a network hub
Connecting Set aside the network cable (yellow) 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 one of the LAN
sockets on the FRITZ!Box.
The FRITZ!Box and the network hub are now connected with
each other.
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 oper-
ating system used. Each computer to be connected to the
FRITZ!Box via WLAN must support WLAN, by means of a
compatible WLAN adapter, for instance the
FRITZ!WLAN USB Stick N.

Connecting the FRITZ!WLAN USB Stick
Connect If you are using a FRITZ!WLAN USB Stick N or a
FRITZ!WLAN USB Stick by AVM as a WLAN adapter, you can
transmit the security settings of the FRITZ!Box to your
FRITZ!WLAN Stick quickly and conveniently using AVM
Stick & Surf. Proceed as follows to do so (described here
using the example of the FRITZ!WLAN USB Stick N):
1. Switch on your computer.
2. Insert the AVM FRITZ!WLAN USB Stick N the USB port
on the FRITZ!Box. The “INFO” LED on the FRITZ!Box be-
gins flashing rapidly.
The WLAN security settings are being transferred to
the FRITZ!WLAN USB Stick N. As soon as the “INFO”
LED stops flashing, transmission of the settings has
been concluded.
3. Remove the FRITZ!WLAN USB Stick N.
4. Now insert the FRITZ!WLAN USB Stick N in the USB
port of the computer.
The security settings saved on the FRITZ!WLAN USB Stick N
are applied to the computer. Now the FRITZ!Box and
FRITZ!WLAN USB Stick N are connected with each other
wirelessly.
Using WLAN adapters from Other Manufacturers
Installing Proceed as follows to install a WLAN adapter from another
manufacturer:
1. Switch on your computer.
For more information on WLAN, see the section “More
about WLAN” from page 122.
For more information, see the manual on the AVM
FRITZ!WLAN USB Stick N or the manual for the AVM
FRITZ!WLAN USB Stick.

2. Install the WLAN adapter in your computer along with
the appropriate software. Please take note of the in-
structions in the documentation of the adapter.
3. In order to establish a WLAN connection to the
FRITZ!Box, you must either use the WLAN software
supplied with the operating system, or the manufac-
turer’s WLAN software included in the WLAN adapter
package.
Establishing a
Connection The FRITZ!Box is delivered with preset values for WLAN se-
curity. You must enter these values during the configuration
of the WLAN adapter.
If you would like to establish a WLAN connection using
these preset values, then your WLAN adapter must support
WPA encryption.
1. Start the WLAN software.
2. Enter the following for the connection between the
FRITZ!Box and the WLAN adapter:
3. Confirm your entries using the relevant button in the
user interface (for instance, “OK” or “Connect”).
Now your WLAN adapter and the FRITZ!Box are connected
with each other wirelessly.
Please see the instructions in the section “Opening the Us-
er Interface” on page 28. See also the information on WLAN
security in the section“Security” from page 125.
