Getting to Know FRITZ!Box
1 Getting to Know FRITZ!Box
This chapter gives you an overview of the features and functions of
your FRITZ!Box 6840 LTE and describes ports, buttons and LEDs.
1.1 FRITZ!Box at a Glance
Access to the Internet
The FRITZ!Box connects multiple computers fast and safely
with the Internet. Other network-compatible devices like
smartphones and game consoles can use the FRITZ!Box for
their Internet connection.
For fast Internet connections via the LTE radio standard, an
LTE modem is integrated into the FRITZ!Box. A preconfigured
firewall protects your network from attacks from the Internet.
The FRITZ!Box also offers a variety of functions to control access to the Internet as well as access from the Internet. The
“Internet filter” feature allows you to restrict access to the Internet for individual Windows users or computers, for instance for you children’s computers. With the integrated VPN
server you can link remote computers securely with the home
network of the FRITZ!Box over the Internet.
WLAN Base Station for Wireless Connections
Computers and other network devices that support WLAN can
be connected wirelessly with the FRITZ!Box. If no WLAN device is integrated in your computer, you can install an external
WLAN adapter like a FRITZ!WLAN USB Stick by AVM (see also
AVM Products for the FRITZ!Box from page 135).
The FRITZ!Box supports the fast WLAN N standard, which provides for data throughput of up to 300 Mbit/s (gross).
You can use the FRITZ!Box in either the 2.4-GHz frequency
band or the 5-GHz frequency band (dual band). Because the
5-GHz frequency band is used less frequently, connections in
this band are subject to less interference.
With the “guest access” feature you can grant friends and visitors fast, secure access to the Internet over your wireless network.

FRITZ!Box at a Glance
Telephone System (PBX)
The FRITZ!Box is a telephone system (or PBX: private branch
exchange) for the Internet telephone line.
The PBX is also equipped with up to five integrated answering
machines and one integrated fax machine for fax reception.
You do not need any more additional devices for these functions. For up to five different telephone numbers in the
FRITZ!Box you can configure a separate answering machine.
The FRITZ!Box can be configured to forward new messages on
an answering machine and new faxes automatically by email.
The FRITZ!Box telephone book is easy to manage in the web
browser. If you use multiple FRITZ!Box cordless telephones on
the FRITZ!Fon, you can use a shared telephone book or set up
a separate telephone book for each FRITZ!Fon in the
FRITZ!Box.
In addition, the FRITZ!Box telephone functions offer convenience features like a call list, call diversion and do not DisturbDo Not Disturb.
DECT Base Station for Cordless Telephones
A DECT base station is integrated in your FRITZ!Box. Up to six
cordless telephones can be connected with the FRITZ!Box:
you do not need an additional base station.
You can use the FRITZ!Box as a DECT base station or as a repeater. When used as a repeater, the FRITZ!Box increases the
range of another FRITZ!Box’s DECT radio network.
Switchboard in the Home Network
The FRITZ!Box connects your computers and other network
devices not only with the Internet, but also with each other.
The connected network devices constitute the home network
of the FRITZ!Box and can exchange data among each other.
You connect computers and other network devices with the
FRITZ!Box either wirelessly via WLAN or using a network cable.

LTE: Radio Standard for Connecting to the Internet
The FRITZ!Box can manage various storage media and make
them available to all participants in the home network. These
include connected USB flash drives, USB hard drives and online storage.
USB 2.0 Port
The FRITZ!Box has a USB port which can be used to integrate
USB devices into your home network, for instance a printer or
a storage medium. The connected USB devices can then be
used simultaneously by all network devices in the home network of the FRITZ!Box.
Media Server for Music, Images, and Video in the Home
Network
As a media server the FRITZ!Box makes music, video and image files available throughout the entire home network. With
suitable playback devices in the home network of the
FRITZ!Box you can even play back the media files when the
computer is turned off.
Your music, video and image files can be stored on a USB
storage medium connected to the FRITZ!Box.
The playback devices or programs, for instance computers or
television sets, must support the UPnP AV or DLNA standard.
1.2 LTE: Radio Standard for Connecting to the Internet
LTE (Long Term Evolution) is a radio standard specified according to the 3GPP standard, Release 8 . Within this standard the FRITZ!Box belongs to category 3 UE (user equipment).
Frequency Ranges
LTE supports two frequency bands:
• 791 - 862 MHz: the LTE band 20 is located in this range.
This band is called the “digital dividend” spectrum.
• 2500 - 2690 MHz: the LTE band 7 is located in this range.

Connecting Computers Wirelessly over WLAN
Please note the following before establishing a wireless connection between the computer and the FRITZ!Box:
• WLAN device
A computer to be connected to the FRITZ!Box via WLAN
must be equipped with a WLAN device for it to support
WLAN. A WLAN device can be an external WLAN adapter—like a USB stick, for example—or a device integrated
in the computer. Many modern computers and notebooks come with a WLAN device integrated.
• WLAN security settings
In the FRITZ!Box, WLAN security settings are enabled upon delivery. Before a computer can establish a wireless
connection to the FRITZ!Box, the WLAN security settings
of the FRITZ!Box must be transferred to the WLAN device.
For this procedure the FRITZ!Box supports the two automatic methods AVM Stick & Surf and WPS (Wi-Fi Protected Setup). The security settings can also be transferred
manually.
For more information on WLAN, see the section FRITZ!Box as
a WLAN Base Station from page 52.

WLAN connection quickly and conveniently.
1. Switch on your computer.
2. Insert the your FRITZ!WLAN USB Stick into the USB port
on the FRITZ!Box.
The WLAN security settings are transmitted to the
FRITZ!WLAN USB Stick. The “Info” LED on the FRITZ!Box
begins flashing quickly.
As soon as the “Info” LED stops flashing, transmission
of the settings has been concluded.
3. Remove the FRITZ!WLAN USB Stick.
4. Now insert the FRITZ!WLAN USB Stick into the USB port
of the computer.
The security settings will be adopted and the WLAN connection between the FRITZ!Box and the FRITZ!WLAN USB Stick
will be established. As soon as the WLAN connection has
been established the computer is connected to the FRITZ!Box.
See the AVM FRITZ!WLAN USB Stick manual for details.
Establishing a WLAN Connection Using WPS
The FRITZ!Box supports WPS (Wi-Fi Protected Setup). WLAN
devices that also support WPS can be connected with your
FRITZ!Box securely using this method. All of the necessary
WLAN security settings are transferred in the process. There
are two kinds of WPS: the push-button method and the PIN
method.

the security settings automatically.
For manual transfer the WLAN security settings have to be entered in the WLAN software.
WLAN devices are generally delivered with their own WLAN
software, which is installed in the computer along with the
WLAN device. By now many operating systems have WLAN
software included. Integrated WLAN devices sometimes use
the operating system’s WLAN software.
Installing a WLAN Device
If you need to use a separate WLAN device because you do
not have one integrated, then install the WLAN device in the
computer along with the corresponding WLAN software.
Please take note of the instructions in the documentation of
the device.

FRITZ!Box as an Internet Router
10 FRITZ!Box as an Internet Router
The FRITZ!Box connects computers in your home network with the Internet. This chapter explains the possibilities offered by using the
FRITZ!Box as an Internet router and how to take advantage of them.
10.1 Child Protection: Restricting Internet Access
The child protection feature allows you to define access rules
to the Internet for individual computers or Windows users.
These access rules may include restrictions of Internet access
time, filter lists and a list with blocked network applications:
• Restrict Internet access time: Using the time restriction
you can restrict the amount of time the user can surf the
web. You can define on which days of the week, at what
times of day, and for how long a computer or Windows
user is allowed to use the Internet connection.
• Block or permit web sites: you can use filter lists to de-
fine which Internet pages are allowed to be accessed
and to which access is blocked. For instance, you can
block all Internet pages the government has defined as
offensive or harmful to minors.
You can create both filter lists, the whitelist and the
blacklist. A whitelist contains all Internet pages to which
access is allowed. A blacklist contains all Internet pages
to which access is blocked.
• Block network applications: You can list network appli-
cations for which Internet access should be blocked. For
instance, you can block Internet access for file-sharing
software.
Child protection can be enabled for each computer individually, regardless of the computer’s operating system.
You can also enable child protection individually in all Windows operating systems (Windows 7, Windows Vista and
Windows XP). This option is very beneficial if a computer is
used by multiple users.

Port Forwarding: Making Computers Accessible from the Internet
Setting Up Child Protection in the FRITZ!Box
1. Open the FRITZ!Box user interface (see page 30).
2. Select the “Internet / Filters” menu.
3. Set up the child protection feature, making use of the
Online Help in the FRITZ!Box user interface.
10.2 Port Forwarding: Making Computers Accessible from the Internet
With default settings in the FRITZ!Box, programs on your computer and LAN cannot be accessed from the Internet. For a
number of applications like online games and file sharing
software, you have to make your computer accessible for other Internet users. In order to grant controlled access to your
computer to other Internet users, you release certain ports for
incoming connections. The ports serve to distinguish between running applications on a computer that has only one
IP address.
Setting Up Port Forwarding in the FRITZ!Box
• Port Forwarding is set up in the “Internet / Permit Ac-
cess”menu.
• Port Forwarding for IPv6 is also set up in the “Internet /
Permit Access” menu, on the “IPv6” page. To see this
page, make sure you enabled the expert mode in the
“System / Expert Mode” menu.
Address for Accessing the FRITZ!Box
If you have enabled the ports for forwarding in the FRITZ!Box,
other users can access your computer at the IP address assigned to your FRITZ!Box by the Internet Service Provider. This
is a public IP address.
Here is how to determine the public IP address of the
FRITZ!Box:
1. Open the FRITZ!Box user interface (see page 30).
2. Enable the expert settings in the “System / Expert
Mode” menu.
44

Dynamic DNS: Name Instead of IP Address
3. Open any Internet page in order to establish an Internet
connection.
4. The FRITZ!Box’s public IP address is displayed on the
“Overview” page in the “Connections” area.
Every time the Internet connection is interrupted the Internet
Service Provider re-assigns the IP address. The IP address
may change in the process. Therefore it is a good idea to use
dynamic DNS so that the IP address can always be reached
under the same name. For more information, see the section
Dynamic DNS: Name Instead of IP Address on page 45.
10.3 Dynamic DNS: Name Instead of IP Address
Dynamic DNS is an Internet service that makes it possible for
the FRITZ!Box to remain accessible from the Internet at all
times under a fixed name, even though the public IP address
changes.
You must register with a dynamic DNS provider to use this
service. When you register, you agree on the fixed name (domain name) at which your FRITZ!Box should be accessible
from the Internet. You also define a user name and password.
Every time the IP address changes, the FRITZ!Box transmits
the new IP address to the dynamic DNS provider in the form of
an update request. Then the domain name is assigned to the
current IP address by the dynamic DNS provider.
Setting Up Dynamic DNS in the FRITZ!Box
1. Open the FRITZ!Box user interface (see page 30).
2. Make sure that the expert mode is enabled in the “Sys-
tem / Expert Mode” menu.
3. Select the “Internet / Permit Access” menu.
4. Select the “Dynamic DNS” page and set up dynamic
DNS. Consult the Online Help available in the FRITZ!Box
user interface for more information.

WLAN).
Setting Up Remote Access over HTTPS in the FRITZ!Box
1. Open the FRITZ!Box user interface (see page 30).
2. Make sure that the expert mode is enabled in the “Sys-
tem / Expert Mode” menu.
3. Select the “Internet / Permit Access” menu.
4. Select the “Remote Access” page and set up dynamic
DNS. For more information, see the Online Help.
10.5 Prioritization: Right of Way for Internet Access
Prioritization is a function you can use to specify that network
applications and network devices be treated with higher or
lower priority when they access the Internet connection. For
example, you may wish to ensure that applications like Internet telephony, IPTV and video on demand are always treated
with higher priority than other applications. You can also
specify that file-sharing applications like eMule and BitTorrent always have to wait behind online games.
Network applications and network devices are assigned to
the categories using rules.
Categories for Prioritization
There are three categories for prioritization: “Real-time applications”, “Prioritized applications” and “Background applications”. The categories are explained below.
Real-time Applications
This category is suitable for applications with high demands
on transmission speed and reaction times (for example, Internet telephony, IPTV, video on demand).
46
Page 47
Prioritization: Right of Way for Internet Access
• Network applications of this category always have priori-
ty over other applications accessing the Internet at the
same time.
• When the Internet connection is working at full capacity,
the network packets of the applications of this category
will always be sent first. In this case data from network
applications assigned to other categories, like “Prioritized applications”, will be transmitted later.
• If multiple network applications are assigned to this cat-
egory, then they must share the available capacity.
• Whenever Internet telephony is included in this catego-
ry, this application always has the highest priority, even
over other real-time applications.
Prioritized Applications
This category is suitable for applications that require a fast reaction time (for example, company access, terminal applications, games).
• For network applications prioritized in this category,
90% of the FRITZ!Box’s upload bandwidth is available,
as long as no application from the “Real-time applications” category requires bandwidth. The remaining 10%
of the upload bandwidth is available for applications
that are prioritized in lower categories or not prioritized
at all.
• If multiple network applications are assigned to the “Pri-
oritized applications” category, then they must share
the available capacity.
Background Applications
This category is suitable for applications that do not require
any high transmission speed and which are not time-critical
(for example, peer-to-peer services or automatic updates).
• Network applications assigned to this category are al-
ways treated with the lowest priority when the Internet
connection is working at full capacity. So whenever an
application from a different category or a non-prioritized
47
Page 48
Prioritization: Right of Way for Internet Access
application requires the entire bandwidth, all background applications must wait until bandwidth capacity
becomes available again.
• If no other network applications are active, then the
background applications receive the entire bandwidth.
Prioritization Method in the FRITZ!Box
The following algorithm is used in the FRITZ!Box to send data
packets according to their prioritization:
• Change in the order in which packets are sent to the In-
ternet (upstream direction)
The order of the packets the FRITZ!Box receives from the
Internet (downstream direction) cannot be changed.
• Discard low-priority packets in order to ensure the trans-
mission of higher-priority packets. This algorithm is
used whenever more packets are supposed to be sent to
the Internet than the upstream transmission rate of the
Internet connection allows.
• As long as no packets are being sent from higher-priority
applications, the full transmission rate of the Internet
connection is available for low-priority packets.
Setting Up Prioritization in the FRITZ!Box
In order to use prioritization, the expert mode must be enabled in the user interface of the FRITZ!Box.
1. Make sure that the expert mode is enabled in the “System
/ Expert Mode” menu.
2. Prioritization is set up in the “Internet / Filters / Prioriti-
zation” menu.

VPN: Remote Access to the Home Network
10.6 VPN: Remote Access to the Home Network
Via VPN (see glossary) a secure remote access to the network
of the FRITZ!Box can be established. The VPN solution for the
FRITZ!Box features the following:
• The VPN solution for the FRITZ!Box is based on the IPSec
standard.
• Computer-LAN coupling and LAN-LAN coupling: VPN con-
nections can be set up for individual remote computers
or even for remote networks.
• A maximum of eight simultaneous active VPN connec-
tions is supported.
• The configuration files for the VPN connections are creat-
ed using a separate program. The program is provided
free of charge and can be downloaded from the AVM web
site.
• A free VPN client for individual computers can also be
downloaded from the AVM web site.
The AVM web site offers a Service Portal which presents comprehensive information on VPN in general and in connection
with the FRITZ!Box. Visit this portal to obtain more detailed information.
www.avm.de/en/vpn
Setting Up VPN in the FRITZ!Box
1. Open the FRITZ!Box user interface.
2. Enable the expert settings in the “System / Expert
Mode” menu.
3. Select the “Internet / Permit Access” menu.
4. Select the “VPN” page.

DNSSEC: Security for DNS Queries
Supplementary Software for VPN
All of the information required for a VPN is saved in a configuration file. The terminals involved in any VPN must receive
this file.
If an individual computer is integrated into a network via a
VPN, the computer must have a VPN client installed.
• “Configure FRITZ!Box VPN Connection” Wizard
AVM provides the “Configure FRITZ!Box VPN” software
for creating configuration files. This program is a Wizard
that takes you step by step through the VPN configuration. All of the necessary VPN settings, like the encryption method and access rules, are set automatically. The
resulting configuration files must be imported to the respective terminals of the VPN tunnel. At the terminal
with the FRITZ!Box the configuration file is then imported
to the FRITZ!Box. The VPN parameters in these files can
be adjusted manually to connect to products by other
manufacturers.
• The “FRITZ!VPN” VPN Client
AVM offers the “FRITZ!VPN” software as a VPN client.
Both the Wizard and the client can be downloaded free of
charge from the VPN Service Portal on the AVM web site:
www.avm.de/en/vpn
10.7 DNSSEC: Security for DNS Queries
DNSSEC is short for Domain Name System Security Extensions. As the name says, this is an extension of DNS, the domain name system.
DNSSEC ensures that both the DNS server and the information returned by the DNS server are authentic, or genuine.
50
Page 51
DNSSEC: Security for DNS Queries
Support with the FRITZ!Box
The FRITZ!Box supports DNSSEC queries over UDP.
The FRITZ!Box has a DNS proxy. The computers in the home
network use the FRITZ!Box as a DNS server. The FRITZ!Box forwards DNSSEC queries from the home network to the Internet. The FRITZ!Box forwards DNSSEC responses from the Internet to the home network.The DNSSEC information must be
validated on the computer in the home network. For this DNSSEC must be supported in the operating system.
Security with DNSSEC
When a home user surfs the web, she or he sends queries to
the Internet by entering URLs in the address line of his browser.
A URL is the name of a web site that is easy to remember, such
as avm.de/en
DNS server resolves the URL into the corresponding IP address.
There is one unambiguous IP address for every URL.
The home user relies on the authenticity of the IP address returned by the DNS server. Authentic means that the response
is the IP address of the desired web site, and not a faked IP
address that leads to a fake web site. DNSSEC can ensure that
the returned addresses are authentic.
. Every query is sent to the DNS server first. The

FRITZ!Box as a WLAN Base Station
11 FRITZ!Box as a WLAN Base Station
The FRITZ!Box supports WLAN (Wireless Local Area Network) technology. In this chapter you will learn how you can use WLAN with the
FRITZ!Box.
11.1 Security
Security is of utmost importance within radio networks.
Radio signals can also be received outside of office or residential spaces and abused for criminal purposes.
Therefore it is important that no unauthorized users can register in a WLAN to use its Internet access or shared network
resources.
FRITZ!Box includes settings on various levels that contribute
to the security of your WLAN and thus to the security of your
computers.
Wireless Network Name (SSID)
In the factory settings of the FRITZ!Box, the name of the wireless network (SSID) is set to “FRITZ!Box 6840 LTE”.
It may occur that an additional device with the same
FRITZ!Box network name is located in the vicinity of your
FRITZ!Box. Therefore we recommend changing the preset radio network name.
11.2 Guest Access: WLAN Connection for Guests
You can connect computers with the FRITZ!Box via WLAN so
that they can access the Internet without being integrated in
the home network of the FRITZ!Box. This function is called
“guest access”.
Your guests can use the guest access, for instance, to surf the
web with a notebook and to receive e-mail.
52
Page 53
Setting Up Night Service for WLAN
Guest Access Properties
• The guest radio network is a separate radio network with
its own name (SSID). It is independent of the wireless
network of the FRITZ!Box that integrates computers in
the home network.
• Computers connected via guest access are not part of
the home network.
• The guest network is secured with its own network key.
This network key can be changed as desired without affecting the computers in your home network.
Setting Up Guest Access in the FRITZ!Box
1. Open the FRITZ!Box user interface.
2. Make sure that the expert mode is enabled in the “Sys-
tem / Expert Mode” menu.
3. Make sure that the wireless radio network (WLAN) is en-
abled in the “WLAN / Radio Network” menu.
4. Select the menu “WLAN / Guest Access” and configure
the guest radio network. For more information, see the
Online Help of the FRITZ!Box.
11.3 Setting Up Night Service for WLAN
In the FRITZ!Box you can set up night service for the WLAN radio network. Then the FRITZ!Box switches to hibernation at
specified times and turns off the radio network. This has the
following advantages:
• reduced power consumption when idle
• time-controlled Internet access: with night service you
can ensure that your children are only allowed to surf the
web until a certain time of day
Switching Night Service for WLAN On and Off
1. Open the FRITZ!Box user interface (see page 30).
2. Select the “System / Night Service” menu.
53
Page 54
Increasing the Range of the WLAN Connection
3. Enable the “Use schedule for WLAN radio network” op-
tion.
4. Enable or disable the option “The radio network cannot
be switched off until no more WLAN devices are active”.
Option enabled: The radio network remains switched on
until all wireless connections between the FRITZ!Box and
other WLAN devices have been ended.
Option is disabled: The radio network is switched off immediately at the start of the specified period.
5. Define the days and times at which the FRITZ!Box WLAN
radio network should be switched off.
6. Save your settings by clicking “Apply”.
Night service for WLAN is now enabled. To disable night service, remove the checkmark in front of “Use schedule for
WLAN radio network” and click “Apply”.
Switching On WLAN during Night Service
The WLAN radio network of the FRITZ!Box can be switched
back on at any time during night service:
Press the WLAN button on the FRITZ!Box or enable the WLAN
radio network using a connected telephone (see page 120).
11.4 Increasing the Range of the WLAN Connection
The range of a WLAN radio network is influenced by various
external circumstances. The following factors have an especially strong influence on the distance over which your
FRITZ!Box can establish a stable, high-throughput wireless
connection:
• the WLAN device used
• structural conditions
• the number of devices operating near the access point in
the same frequency range.
54
Page 55
Increasing the Range of the WLAN Connection
If needed, you can extend the range of your WLAN radio network with a WLAN repeater, for instance with the FRITZ!WLAN
Repeater N/G or FRITZ!WLAN Repeater 300E from AVM. A
WLAN repeater is a supplementary device that is not included
in the FRITZ!Box package.
Instead of using a WLAN repeater, you can set up a Wireless
Distribution System. For this you need, in addition to the
FRITZ!Box, another WLAN access point that is configured as a
WDS repeater (see page 55).
Using the FRITZ!WLAN Repeater
With the FRITZ!WLAN Repeater N/G from AVM you can extend
the range of your WLAN radio network quickly and easily, for
instance to overcome structural conditions that are characterized by thick materials and heavy shielding. The FRITZ!WLAN
Repeater N/G supports all common WLAN standards, is especially easy to install and can be operated at any 230-V power
outlet. For more information on the FRITZ!WLAN Repeater
N/G, see the web site at:
www.avm.de/en/Produkte/FRITZ_WLAN/FRITZ_WLAN_
Repeater_N_G
Setting Up a WDS
To use WDS (Wireless Distribution System) to increase the
range of your WLAN radio network, you need another WLAN
base station in addition to the FRITZ!Box. This can be a second FRITZ!Box or any other WLAN base station that supports
WDS. The first WLAN base station then works as a WDS base
station and the second as a WDS repeater.
The WDS base station and WDS repeater are connected to
each other via WLAN. The WDS base station then can use the
WDS repeater to reach even computers that are outside its
own range, but within the range of the WDS repeater.

WDS: Expanding the WLAN range using a WDS repeater
Note the following for WDS configuration:
• To expand the range of your wireless network, you need
at least one additional WLAN base station. The wireless
network of your FRITZ!Box can be expanded to a WDS
(Wireless Distribution System) with up to three WLAN
base stations.
• All WLAN base stations implemented in the WDS must
support WDS and be configured for this technology.
• All WLAN base stations implemented as repeaters in the
WDS must be located within the radio range of the WDS
base station.
• The FRITZ!Box can function as a WDS base station to es-
tablish the Internet connection for other WDS repeaters,
or as a WDS repeater to expand the range of a WDS base
station.
• All WDS connections between the WDS base station
and the WDS repeaters must be secured using the
same encryption (e.g. WPA/WPA2). Note that the WPA2
encryption method is available only when your network
consists of AVM devices, since in the WLAN standard only WEP encryption has been specified for WDS connections.
• All WLAN base stations in the WDS must use the same
radio channel.
56
Page 57
WLAN Standards
• Every WLAN base station participating in the WDS fulfills
the tasks of a WLAN access point for its WLAN clients.
This means that the WLAN clients see each WLAN base
station with an individual name (SSID) and individual
encryption settings.
If you use the WLAN control software provided in
Windows 7, Windows Vista or by the Windows XP Service
Pack 2 on your WLAN clients, you can assign the same
SSID and the same encryption settings to different WLAN
base stations. Each client can then automatically register
at the WLAN base station with the best availability.
• Each IP address may be assigned only once in the wire-
less network.
11.5 WLAN Standards
The WLAN standards IEEE 802.11a, IEEE 802.11b,
IEEE 802.11g, IEEE 802.11n and IEEE 802.11i were developed by the Institute of Electrical and Electronic Engineers
(IEEE).
The IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and
IEEE 802.11n standards define the throughput within a wireless radio network. IEEE 802.11i is a security standard.
Standards for the Throughput Rate
Data Throughput
The throughputs listed differentiate between gross and net
transmission rates. The net speed describes the transmission
rate of the user data.
The FRITZ!Box supports your choice of the standards
IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and IEEE 802.11n.
WLAN devices based on one or more of the standards listed
can be used for WLAN connections with the FRITZ!Box.
57

WLAN Standards
Standard Frequency Band
802.11b 2.4 GHz 11 Mbit/s 5 Mbit/s
802.11g 2.4 GHz 54 Mbit/s 25 Mbit/s

802.11n 2.4 / 5 GHz 300 Mbit/s 150 Mbit/s
Gross Data Throughput up to
Net Data Throughput up to
The standards are intended for different frequency bands.
IEEE 802.11a
Because this standard works exclusively in the seldom used
5-GHz range, it offers the opportunity to transmit data relatively free of interference from external influences. WLAN devices that support 802.11a are much less common than devices that work in accordance with the 802.11b/g standard.
IEEE 802.11b
With a maximum throughput rate of 11 Mbit/s, this is the oldest WLAN standard. Older WLAN devices of the first generation can communicate with the FRITZ!Box using 802.11b.
However, if the WLAN device supports newer standards such
as 802.11g, the latest standard should be used.
IEEE 802.11g
This is currently the most common WLAN standard. It communicates with a maximum of 54 Mbit/s gross in the 2.4-GHz
frequency range (ISM) and guarantees broad compatibility
with many WLAN devices.
However, due to heavy use of the 2.4-GHz range, interference
is more common than in the less-used 5-GHz range.
IEEE 802.11n
This standard allows for high throughput rates and ranges.
The FRITZ!Box supports 802.11n in the 2.4-GHz frequency
band, or, if desired, also in the 5-GHz frequency band. Modulation processes and antenna techniques like MIMO (Multiple
Input, Multiple Output) use whichever frequency band is
available more effectively than the older standards.
58
Page 59
WLAN Standards
The use of the 802.11n standard—and thus the availability
of higher throughput rates—is possible only if the WLAN connection is secured using the WPA2 security mechanism (AESCCMP).
Thanks to compatibility with the 802.11g standard, you can
also continue to use older WLAN devices.
Setting the Right Standard in the FRITZ!Box
The throughput rate that can be achieved in your WLAN radio
network depends on the WLAN standards used by the integrated WLAN devices. These WLAN standards must also be
set in the FRITZ!Box. Proceed as follows to check which WLAN
standards are set and change them if needed:
1. Open the FRITZ!Box user interface.
2. Make sure that the expert mode is enabled in the “Sys-
tem / Expert Mode” menu.
3. Open the “WLAN / Radio Channel” menu and select “Ad-
just radio channel settings” to make the desired changes.
Note the following for the configuration of this setting:
• In order to communicate with each other, the FRITZ!Box
and all WLAN devices must work in the same frequency
band.
• The standard you configure in the FRITZ!Box must be
compatible with the standards of all WLAN devices used
in the WLAN.
Make a note of which standards the WLAN devices in your
network are compatible with and then adjust the FRITZ!Box
settings according to the following information:
59
Page 60
WLAN Standards
• Your radio network integrates only WLAN devices that
are compatible with one or both of the following standards:
802.11n
802.11g
Set the following mode in the FRITZ!Box:
Mode: 802.11n+g
The 2.4-GHz frequency band will be used.
• Your radio network integrates only WLAN devices that
are compatible with one or both of the following standards:
802.11b
802.11g
Set the following mode in the FRITZ!Box:
Mode: 802.11b+g
The 2.4-GHz frequency band will be used.
• Your radio network integrates only WLAN devices that
are compatible with one or several of the following standards:
802.11n
802.11g
802.11b
Set the following mode in the FRITZ!Box:
Mode: 802.11n+g+b
The 2.4-GHz frequency band will be used.
60
Page 61
WLAN Standards
• Your radio network integrates only WLAN devices that
are compatible with one or both of the following standards:
802.11n
802.11a
Set the following mode in the FRITZ!Box:
Mode: 802.11n+a
The 5-GHz frequency band will be used.
The Standard for Security
IEEE 802.11i
The WPA2 security mechanism is defined in the IEEE 802.11i
standard. WPA2 is an extension of the familiar security mechanism WPA (Wi-Fi Protected Access).
The main feature of the extension of WPA to WPA2 is the AESCCMP encryption process.
Mechanism Encryption
WPA TKIP (Temporary Key Integrity Protocol)
WPA2 TKIP
AES-CCMP
based on the extremely secure AES (Advanced
Encryption Standard) procedure. CCMP (Counter Mode with CBC-MAC Protocol) defines how
the AES procedure is applied to WLAN packets.
FRITZ!Box supports the AES encryption procedure as part of
the WPA2 mechanism, and the TKIP encryption procedure as
part of the WPA mechanism. This means that the FRITZ!Box
can be used in combination with any WLAN devices that also
support WPA2 with AES or WPA with TKIP.
61
Page 62
Frequency Ranges
11.6 Frequency Ranges
WLAN uses the frequency ranges at 2.4 GHz and 5 GHz as its
transmission range.
With the FRITZ!Box you can establish WLAN connections in either the 2.4-GHz or the 5-GHz frequency range.
2.4-GHz Frequency Band
In the 2.4-GHz frequency band WLAN works in the same range
as Bluetooth, microwave devices and various other devices
like radio-controlled toys, garage-door openers and video
bridges. This means that interference may occur within
WLANs operated in the vicinity of such devices. Generally this
has adverse effects on the transmission rate, including aborted connections.
In the 2.4-GHz frequency range the European regulation authorities have designated 13 channels for WLAN. A channel
can have a bandwidth of 20 MHz (throughput up to
130 Mbit/s) or 40 MHz (throughput of up to 300 Mbit/s).
Channels located directly next to each other in the 2.4-GHz
band may overlap and result in mutual interference. For instance, if several WLANs are operated close to each other in
the 2.4-GHz frequency range with a bandwidth of 20 MHz, a
distance of at least five channels should be left empty between each two channels used. This means that if channel 1
is selected for one WLAN, the channels 6 through 13 can be
selected for a second WLAN. This maintains the minimum distance between channels.
Should interference in a WLAN persist, the first step should
be to select a different channel.
WLAN Autochannel
With the WLAN autochannel function, the FRITZ!Box automatically searches for the channel subject to the least interference. This process takes into consideration interference from
radio networks in the vicinity (WLAN base stations) and potential sources of interference (for instance video bridges,
62
Page 63
Frequency Ranges
baby monitors, microwave ovens). Should problems with interference persist despite this function, try to identify the
source of interference and switch it off manually.
Additional tips on interference in the WLAN radio network are
presented in the section Ruling Out Interference Caused by
Other Wireless Networks from page 118.
5-GHz frequency band
The FRITZ!Box can operate in the 5-GHz frequency band as an
alternative. This frequency range is used much less often
than the most common 2.4-GHz frequency range.
In the 5-GHz frequency band the FRITZ!Box supports automatic channel switching by DFS (Dynamic Frequency Selection).
DFS ensures that the channels from 52 to 140 are kept free
for higher priority users, like weather radar systems. If you are
operating your FRITZ!Box in one of these channels, it monitors the selected channel periodically for higher priority users, and, if necessary, switches to a different channel. Note
that the FRITZ!Box waits up to ten minutes, as legally required, before occupying a free channel. During this period
you cannot register any WLAN devices. The WLAN connection
is then established automatically. For more information, see
the section Avoiding WLAN Channels with DFS on page 117.
A prerequisite for use of the 5-GHz frequency band is that all
WLAN devices in the network support this frequency range in
accordance with the IEEE 802.11a or IEEE 8002.11n standard.
2.4GHz or 5GHz
The FRITZ!Box works in the wireless network either in the 2.4GHz range or in the 5-GHz range, but not parallel in both frequency ranges at the same time.
Bandwidth
In both frequency ranges you can select between channel
bandwidths of 20 MHz or 40 MHz (exception: channel 140 in
the 5-GHz frequency band). The FRITZ!Box initially attempts
to select a channel with 40 MHz bandwidth (throughput up to
300 Mbit/s). If this is not possible due to interference or
63
Page 64
Frequency Ranges
channels already being used by other WLANs in the vicinity,
the FRITZ!Box automatically switches temporarily to a channel with 20 MHz bandwidth. Greater bandwidth provides for
higher data throughput:
Bandwidth (MHz) Maximum Data Throughput (Mbit/s)
20 130
40 300
Increasing bandwidths also increases the probability of interference by wireless networks in the vicinity. Large bandwidths
reduce the frequency range available to other wireless networks in the vicinity.

FRITZ!Box as a Telephone System
12 FRITZ!Box as a Telephone System
The FRITZ!Box is a telephone system (or PBX: Private Branch Exchange) for Internet telephony. This chapter describes convenience
functions for the telephone system that can be configured in the
FRITZ!Box user interface, for instance telephone books, answering
machines and call diversion.
You will also find out which convenience functions can be used to
make calls, for instance internal calling, alternating between calls,
fowarding calls and three-party conferences.
12.1 Using the Telephone Book and Call List
Telephone Book
A telephone book is at your disposal in the FRITZ!Box. In the
user interface the FRITZ!Box telephone book is found in the
“Telephony” menu.
If a cordless telephone from AVM (for instance FRITZ!Fon MTF) is registered on the FRITZ!Box, you can use the telephone
book directly on the cordless telephone. If multiple AVM cordless telephones are registered, you can set up an individual
telephone book for each cordless telephone in the FRITZ!Box.
Call List
In the call list the FRITZ!Box saves outgoing and incoming
calls, missed calls, and sent and received faxes.
In the FRITZ!Box user interface the call list is found in the “Telephony” menu.
If the number of a caller or someone called is entered in the

15 Network Devices in the FRITZ!Box Home Network
All network devices connected with the FRITZ!Box comprise a network.
Network devices include, for instance, computers, game consoles and
smartphones. The devices can be connected with the FRITZ!Box by cable or wirelessly. This chapter describes the network settings in the
FRITZ!Box and how you can change them. You will also learn how you
can change the IP settings for the computer in the most common operating systems.
15.1 Network Settings in the FRITZ!Box
The FRITZ!Box is delivered with preconfigured network settings. According to these settings, all network devices connected with the FRITZ!Box are located in a single network.
The network settings can be changed and adapted to your
conditions and needs. But you should do so only if you are
well versed in networking technology.
The Glossary (from page 146) explains concepts and terminology having to do with IP networks.
Network Overview
The FRITZ!Box user interface shows an overview with all of the
devices and users connected with the FRITZ!Box.
The network overview “Devices and Users” is found in the
menu “Home Network / Network”.

FRITZ!Box can be changed here.
Button for deleting the entry
Users or network devices that do not have an active connection to the FRITZ!Box can be deleted
from the network overview by clicking this button.
Always Assigning the Same IP address
The editing mode for network devices includes the setting
“Always assign this network device the same IP address”.
When this setting is enabled for a network device, the DHCP
server of the FRITZ!Box will always assign the same IP address
to this device each time the connection is established.
88
Page 89
Network Settings in the FRITZ!Box
Starting the Computer – Wake on LAN
The editing mode for network devices that are connected with
the FRITZ!Box via a network (LAN) port includes the “Start
Computer” button. Use this button to start computers that
support wake on LAN.
With the wake on LAN function you can start computers in
your FRITZ!Box via the Internet. For instance, you can access a
computer at any time using remote maintenance software,
without wasting electricity by keeping the computer switched
on permanently.
IP Settings in the FRITZ!Box
The IP settings of the FRITZ!Box are preset upon delivery with
the following values:
FRITZ!Box Factory Settings
IP address 192.168.178.1
Subnet mask 255.255.255.0

The IP address and the corresponding subnet mask yield the
following values:
Network address of the subnet 192.168.178.0
Entire IP address range for the computers
192.168.178.2 -
192.168.178.254
The following addresses cannot be assigned because they
are reserved for certain purposes:
This IP address is used by the

IP Address in the FRITZ!Box
Upon delivery the FRITZ!Box is assigned the following IP address:
192.168.178.1
If you would like to change the IP address, please read
through the following sections.
When Does It Make Sense to Change the IP Address?
You should change the IP address of the FRITZ!Box if the following apply to your network:
• You have an existing local IP network, one subnet with
several computers.
• Fixed IP addresses are registered in the network settings
of the computer, and you do not want to or are not permitted to change these addresses.
• You want to connect the FRITZ!Box to the local IP network
in order to make the FRITZ!Box features available to all of
the computers in the IP network.
Reserved IP Addresses
The entire IP network 192.168.180.0 in the FRITZ!Box is reserved for internal purposes.
IP addresses from this network may not be assigned to the
FRITZ!Box.
DHCP Server of the FRITZ!Box
The FRITZ!Box is equipped with its own DHCP server. The
DHCP server is enabled by default in the factory settings. The
following range of IP addresses is reserved for the DHCP server in the factory settings:
192.168.178.20 - 192.168.178.200
This IP address can be changed as needed.
Every time the operating system on a computer connected
with FRITZ!Box is started, the DHCP server assigns it an IP address from the IP address range of the DHCP server.
90
Page 91
Network Settings in the FRITZ!Box
Only one DHCP server may be active within any network.
Assigning the IP addresses via the DHCP server ensures that
all of the computers connected with the FRITZ!Box are located
in the same IP network.
The computers can receive their IP addresses from the DHCP
server only if the setting “Obtain an IP address automatically” is enabled in the their IP settings. For more information,
see the section Obtaining an IP Address Automatically from
page 93.
Fixed IP Addresses when the DHCP Server Is Enabled
If you would like to configure fixed IP addresses on individual
computers connected with the FRITZ!Box despite the enabled
DHCP server, please note the following:
• The IP addresses must be from the IP network of the
FRITZ!Box.
• The IP addresses may not come from the address range
of the DHCP server.
• Each IP address can be assigned only once.
Disabling the DHCP Server
You can disable the DHCP server.
To make sure that all computers remain in the same IP network when the DHCP server is disabled, you must enter the IP
addresses manually in the computers’ network settings. First
disable the option “Obtain an IP address automatically” and
then enter the IP address manually in the appropriate field.
In the case of the preset IP address of the FRITZ!Box, the following IP addresses are available for assignment to the computers:
192.168.178.2 - 192.168.178.254

5. Make the desired changes and then confirm with “OK”
so that all changes will be applied.
Please note that changes to the network settings in the
FRITZ!Box may make it necessary to adjust the network settings of your computers so that you can continue to access
the FRITZ!Box user interface.
UPnP Settings
The Universal Plug-and-Play (UPnP) service included in your
FRITZ!Box provides status information about the FRITZ!Box to
all connected computers. Programs with UPnP support on
these computers can receive this information and use them
to display the status of the FRITZ!Box (e.g., connection status,
data transmission). UPnP service thus allows you to monitor
your FRITZ!Box from a connected computer.
Here is how to change the UPnP settings:
1. Open the FRITZ!Box user interface (see page 30).
2. Make sure that the expert mode is enabled in the “Sys-
tem / Expert Mode” menu.
3. Configure the UPnP settings in the “Home Network / Net-
work” menu on the “Programs” page.

Obtaining an IP Address Automatically
15.2 Obtaining an IP Address Automatically
The FRITZ!Box has its own DHCP server, which assigns IP addresses to the connected computers. The connected computers must be configured such that they can receive their IP addresses automatically. The steps for checking and adjusting
this option differ among the operating systems. See the relevant section for your operating system.
If FRITZ!Box is operated in a network, no other DHCP server
may be activated in this network.

USB Devices in the FRITZ!Box Home Network
16 USB Devices in the FRITZ!Box Home Network
The FRITZ!Box has a USB port to which you can connect various USB
devices. All network devices in the FRITZ!Box home network can use
these USB devices jointly and simultaneously.
This chapter describes how to share a printer in the network, which
USB devices can be used in your FRITZ!Box home network, and how to
use these devices safely.
16.1 Power Supply for USB Devices
You can connect USB devices with the following properties to
the FRITZ!Box:
• Some USB device require more than one USB port for op-
eration, for instance, hard drives with a USB Y cable.
Connect this type of USB devices to the FRITZ!Box using
a USB hub with its own power supply.
• The total current consumption of connected USB devices
without their own power supply may not exceed 500 mA.
Check the rating plates of the connected USB devices.
USB devices that exceed the total current consumption
of 500 mA can be connected to the FRITZ!Box using a
USB hub with its own power supply.
16.2 USB Devices on the FRITZ!Box
These USB devices can be connected to the FRITZ!Box:
• You can connect up to four USB storage media like hard
disks, USB flash drives or card readers.
• USB storage media must use the file systems EXT2, FAT,
FAT32 or NTFS. On storage media with the FAT and FAT32
file systems you can use files up to a size of 4 GB. In the
NTFS file system there is no limit to the size of files that
can be used.
• You can connect one standard USB printer or one all-in-
one device with scanner and fax function. The complete
range of functions available in a all-in-one printers

device is guaranteed only with the USB remote connection of the FRITZ!Box (see also: Sharing a USB Printer on
page 99).
• You can connect a USB hub to the FRITZ!Box and use up
to four USB devices at this hub.
You can use USB hubs with or without a separate power
supply. We recommend deploying a USB hub with its
own power supply if the USB devices to be connected exceed a total current consumption of 500 mA (see also:
Power Supply for USB Devices on page 97).
• You can connect a USB stick from the FRITZ!WLAN USB
Stick series by AVM to conveniently establish secure
WLAN connections using AVM Stick & Surf (see:
Establishing a WLAN Connection with AVM Stick & Surf
on page 25).
16.3 Using USB Devices Safely
Follow the instructions below about how to use USB devices
on your FRITZ!Box.
• The FRITZ!Box can not defend the USB memory from ex-
ternal influences. This means that voltage spikes or
drops, like those that occur during electrical storms, may
lead to data losses on connected USB memory media.
We recommend making regular backups of the USB
memory contents to avoid any losses.
• Whenever you want to remove USB devices from the
FRITZ!Box, go to the “Home Network / USB Devices” area
in the FRITZ!Box user interface to remove them safely
and avoid any loss of data.

Accessing USB Memory
16.4 Accessing USB Memory
The participants in the home network have various possibilities for accessing the various memory media of the FRITZ!Box.
• Participants in the home network can use FTP software
like FireFTP to exchange files among the FRITZ!Box storage media and workplaces.
Alternatively, you can enter ftp://fritz-box
line of your Internet browser to access the memory of the
FRITZ!Box.
If you would like to use FTP software, see the documentation of the software as well as the instructions in the
Online Help of the FRITZ!Box user interface.
• For access to media data like music, images and videos
available on the memory of the FRITZ!Box you can enable
the FRITZ!Box media server. Suitable playback devices
like TV sets, web radios, smartphones and the Windows
Media Player can then call up the data for streaming
from the media server.
Playback devices to be used in connection with the media server must support the UPnP/AV standard.
Enable the “media server” function in the FRITZ!Box user
interface under “Home Network / Storage (NAS) / Options Enabled”.
16.5 Sharing a USB Printer
You can connect a USB printer to the USB port of the
FRITZ!Box to make it available to all participants in your home
network. You can either release the printer for sharing as a
network printer or use the FRITZ!Box USB remote connection
software to connect it with a computer. Which option is preferable depends on how you intend to use the printer.
