Transferring the WLAN Security Settings Manually
The WLAN security settings for WLAN devices can also be
transferred manually. Manual transfer is unavoidable if a
WLAN device does not support any methods for transferring
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.
Transferring WLAN Security Settings
The values for WLAN security preconfigured in the FRITZ!Box
have to be transferred to the WLAN device.
The values preset in the FRITZ!Box are printed on the sticker
attached to the bottom of the housing. If you would like to
establish a WLAN connection using these values, then your
WLAN device must support the preset encryption method. If
this is not the case, first change the settings in the FRITZ!Box.
To do this, connect your computer and the FRITZ!Box using a
network cable.
1. Start the WLAN software.
2. The following table presents the values that are possible
for the connection between the FRITZ!Box and the WLAN
device. Enter in the WLAN software the values set in the
FRITZ!Box. If you changed the preconfigured values in
the FRITZ!Box, then enter these changed values in the
WLAN software.

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 for all Windows users in all Windows operating systems (Windows 7,
Windows Vista and Windows XP). This option is useful if a
computer is used by multiple users.
FRITZ!Box 3370 41
Port Forwarding: Making Computers Accessible from the Internet
The child protection feature is available only if you have set
up the Internet connection in the FRITZ!Box and established
an Internet connection. Child protection is not available if you
have configured the FRITZ!Box as an IP client. In this case, use
the corresponding functions of the router whose Internet connection is being shared.
Setting Up Child Protection in the FRITZ!Box
1. Open the FRITZ!Box user interface (see page 26).
2. Select the “Internet / Filters” menu.
3. Set up child protection. See the Online Help available in
the FRITZ!Box user interface for more information.
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 applications like online games and file sharing software or server services like HTTP, FTP, VPN, terminal and remote access
servers you have to make your computer accessible for other
Internet users.
Port Forwarding
Using port forwarding, you allow incoming connections from
the Internet. By releasing certain ports for incoming connections, you grant controlled access to your computers in your
network to other Internet users. Ports serve to assign incoming data packets to the various applications when all applications can be accessed at one IP address only.
The following port forwarding methods are possible in the
FRITZ!Box:
FRITZ!Box 3370 42
Port Forwarding: Making Computers Accessible from the Internet
PING IPv4:
The FRITZ!Box responds to ping inquiries from
the Internet addressed to the IPv4 address of the
FRITZ!Box.
IPv6:
The FRITZ!Box responds to ping inquiries from
the Internet addressed to the IPv6 address of the
FRITZ!Box. Additionally, you can set up PING6
port forwarding rules for each computer in the
home network since each computer has its own
globally valid IPv6 address.
TCP
UDP
ESP
GRE
Exposed Host
(Open firewall
completely)
IPv4:
Within IPv4 networks you can open the FRITZ!Box
firewall for the protocols TCP and UDP when entering the port range. One port can be opened for
exactly one computer.
IPv6:
Within IPv6 networks you can open the FRITZ!Box
firewall for the protocols TCP and UDP when entering the port range. One port can be opened for
each computer in the network.
IPv4:
Within IPv4 networks you can open the firewall
for the two protocols ESP and GRE which do not
use ports.
IPv4:
Within IPv4 networks you can open the firewall
for one computer completely. This computer is
then no longer protected by the FRITZ!Box firewall. If individual ports are already open for other
computers, then data packets for these ports are
not forwarded to the exposed host but to the other computer instead.
IPv6:
Within IPv6 networks you can open the firewall
for each computer completely. These computers
are then no longer protected by the FRITZ!Box
firewall.

• IPv6: Enable the advanced view. Port forwarding for IPv6
is also set up in the “Internet / Permit Access” menu, on
the “IPv6” page.
Determining the IPv4 Address for Accessing the FRITZ!Box
If you have enabled ports for forwarding in the FRITZ!Box, other Internet users can access your computers at the IP address
assigned to your FRITZ!Box by the Internet service provider.
This is a public IPv4 address.
Here is how to determine the public IPv4 address of the
FRITZ!Box:
1. Open any Internet page in order to establish an Internet
connection.
2. Open the FRITZ!Box user interface and enable the ad-
vanced view in the user interface.
3. The FRITZ!Box’s public IPv4 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
MyFRITZ! or dynamic DNS so that the IP address can always
be reached under the same name. For more information
about MyFRITZ!, see the section MyFRITZ!: Global Access to
the FRITZ!Box on page 38. For more information about dy-
namic DNS, see the section Dynamic DNS: Name Instead of
IP Address on page 45.
FRITZ!Box 3370 44
Dynamic DNS: Name Instead of IP Address
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.
Dynamic DNS can be used as an alternative to MyFRITZ!. Both
services can be used in parallel.
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 26).
2. Enable the advanced view.
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.
10.4 Remote Access over HTTPS
With this function it is possible to access the user interface of
the FRITZ!Box from another location. This allows you to configure settings in the FRITZ!Box or perform a FRITZ!OS update
using a computer that is not in your own network (LAN or
WLAN).
Setting Up Remote Access over HTTPS in the FRITZ!Box
1. Open the FRITZ!Box user interface (see page 26).
2. Enable the advanced view.
3. Select the “Internet / Permit Access” menu.

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 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.
Categories for Prioritization
There are three categories for prioritization: “Real-time applications”, “Prioritized applications” and “Background applications”. The categories are explained below.
Network applications and network devices are assigned to
the categories using rules.
Real-time Applications
This category is suitable for applications with high demands
on transmission speed and reaction times (for example, IPTV
or video on demand).
• 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.
FRITZ!Box 3370 46
Prioritization: Right of Way for Internet Access
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
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.
FRITZ!Box 3370 47
VPN: Remote Access to the Home Network
• 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
1. Enable the advanced view.
2. Prioritization is set up in the “Internet / Filters / Prioriti-
zation” menu.
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.

3. Select the “Internet / Permit Access” menu.
4. Select the “VPN” page.
See the Online Help of the FRITZ!Box to set up VPN.
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.
Individual computers that are networked over a VPN require a
VPN client.
• “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:

DNS Server: Freely Selectable
10.7 DNS Server: Freely Selectable
DNS servers are preset in the FRITZ!Box for IPv4 and IPv6.
These are the DNS servers assigned by the Internet service
provider.
For both IPv4 and IPv6, the preset DNS server can be replaced
by a free DNS server. Free DNS servers include, for instance,
OpenDNS and Google DNS.
Here is how to change the DNS server entry:
1. Open the FRITZ!Box user interface.
2. Enable the advanced view.
3. In the “Internet / Account Information” menu, select the
“DNS Server” page.
4. Change the settings for the DNS servers.
The “DNSv6” page is displayed only if you enabled IPv6
support for the FRITZ!Box on the “IPv6” page.
10.8 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.
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 the browser. A URL is the name of a web site that is easy to remember,
such as www.avm.de/en
er first. The DNS server resolves the URL into the corresponding IP address. There is one unambiguous IP address for every URL.
FRITZ!Box 3370 50
. Every query is sent to the DNS serv-
IPv6: The New Internet Protocol
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.
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.
10.9 IPv6: The New Internet Protocol
IPv6 stands for Internet protocol version 6 and is the successor to IPv4.
The FRITZ!Box supports the new IPv6 web protocol and can
establish IPv6 connections:
• IPv6 support can be switched on in the FRITZ!Box user
interface.
• For simultaneous use of IPv6 and IPv4, the FRITZ!Box
supports dual-stack and dual-stack lite. This means that
the FRITZ!Box can communicate with both IPv4 and IPv6
domains in the Internet.
• The FRITZ!Box supports native IPv6 and IPv6 with a tun-
nel protocol. Native IPv6 means that your Internet service provider supports IPv6 directly on your line.
FRITZ!Box 3370 51
IPv6: The New Internet Protocol
IPv6-capable Services in the Home Network
• FRITZ!NAS access via SMB or FTP/FTPS
• access to the user interface with http or https over IPv6

Windows XP.
• IPv6 has been available in the Mac OS X operating sys-
tems since Mac OS 10.
10.10Mobile Network: Replace Faulty DSL
Internet access over the mobile telephone network can be set
up so that the mobile telephone connection is established
automatically whenever the DSL connection fails. This guarantees Internet access even when the DSL connection is
missing. A USB modem for mobile Internet access
(UMTS/HSPA) and a SIM card from a mobile communications
provider are required for this. The FRITZ!Box supports
UMTS/HSPA modems from various manufacturers.
Here is how to set up the mobile telephone connection as a
substitute upon DSL failure:
1. Insert the USB modem in the USB port on the FRITZ!Box.
2. Open the FRITZ!Box user interface (see page 26).
In the “Internet” menu, the sub-menu “Mobile Telephone Network” is displayed.
The “Mobile Telephone Network” menu is not available
until the UMTS/HSPA modem has been connected to the
USB port of the FRITZ!Box.
3. Select the setting “Automatically enable the mobile con-
nection when the DSL connection is disrupted”.

FRITZ!Box as a WLAN Base Station
11 FRITZ!Box as a WLAN Base Station
The FRITZ!Box is a WLAN base station for WLAN devices like notebooks,
tablets or smartphones. The FRITZ!Box can establish WLAN connections
compliant with the fast WLAN N standard in two different frequency
bands at the same time. The FRITZ!Box is preconfigured with an encryption method from today’s safest method WPA2. This encryption method
is supported by most of the latest WLAN devices. The FRITZ!Box supports wireless LAN convenience functions like guest access, night service and WPS Quick Connection.
11.1 Connecting WLAN Devices Securely with the FRITZ!Box
In a WLAN radio network security is of the utmost importance.
This is why WLAN connections between the FRITZ!Box and
your wireless devices are encrypted. For encryption the
FRITZ!Box and your wireless devices must use the same encryption method. The FRITZ!Box is preconfigured with an encryption method that combines today’s safest methods WPA
and WPA2. These encryption methods are supported by most
of the latest wireless devices.
If you would like to use wireless devices that do not support
WPA2 or WPA, you can switch encryption in the FRITZ!Box to
the older, less secure WEP method. You can also establish
non-encrypted wireless LAN connections. However, if at all
possible we recommend always establishing WPA2 wireless
LAN connections.
WLAN devices can be connected with the FRITZ!Box automatically or manually. A particularly simple and secure automatic
method is WPS, with which a WLAN connection can be established at the touch of a button. For manual WLAN connections
with the FRITZ!Box use the WLAN software of your WLAN device or the WLAN program on your computer.
Connecting WLAN Devices Automatically (WPS)
WLAN devices that support the fast connection method WPS
can be connected with the FRITZ!Box automatically.
1. Start the WPS function of your WLAN device. Consult the
documentation of the WLAN device to find out how to
start WPS.
FRITZ!Box 3370 55
Connecting WLAN Devices Securely with the FRITZ!Box
2. Press the WLAN button on the FRITZ!Box until the
“WLAN” LED begins flashing. You have 2 minutes for this
task.
3. Your WLAN device and the FRITZ!Box now establish a se-
cure WLAN connection automatically. The FRITZ!Box
“WLAN” LED stops flashing and remains on.
With this, the WLAN connection is established. Your WLAN device is integrated into your home network and can use the Internet connection of the FRITZ!Box.
Connecting WLAN Devices Manually
You can connect WLAN devices with the FRITZ!Box manually.
WLAN devices like notebooks, tablets and smartphones use
the WLAN software of their own operating system for this connection. A WLAN adapter at the USB port of your computer
can use the WLAN software of your computer or a WLAN program of your own. No matter what program is used to establish the WLAN connection, the principle is the same: the
WLAN software searches for a WLAN radio network in the vicinity and, after authorization with a WLAN key, enables the
WLAN connection between the FRITZ!Box and your WLAN device.
1. Make sure that the WLAN function of the FRITZ!Box is en-
abled and the “WLAN” LED is on. If “WLAN” is not on,
press the “WLAN” button briefly.
2. Start the WLAN software of your WLAN device. Consult
the documentation of your WLAN device for instructions.
3. Search for the WLAN radio network of your FRITZ!Box.
Upon delivery this network is called
“FRITZ!Box WLAN 3370”.
4. Enter the WLAN key of the FRITZ!Box.
With this, the WLAN connection is established. Your WLAN device is integrated into your home network and can use the Internet connection of the FRITZ!Box.
FRITZ!Box 3370 56

11.2 Connecting WLAN Devices with the FRITZ!Box Guest Access
With the FRITZ!Box you can provide your guests with an Internet connection of their own. At this guest access they can surf
the web with their own smartphones or tablets, but cannot
access the contents of your home network.
You can set up a guest access if you have connected the
FRITZ!Box directly to your DSL line. If the FRITZ!Box is connected in another way, for instance to a cable modem, you cannot
set up guest access.
1. Open the FRITZ!Box user interface.
2. Make sure that the wireless radio network (WLAN) is en-
abled in the “WLAN / Radio Network” menu.
3. Select the “WLAN / Guest Access” menu and enable
guest access.
4. Assign a name for the guest wireless network (SSID) and
enter a WLAN key at least 20 characters long under “Security”.
This concludes the setup of your guest access. Now guests
can register their WLAN devices with the FRITZ!Box.
1. Your guest starts the WLAN software of his WLAN device,
searches for your guest wireless network and enters the
WLAN key you specified for authorization.
2. The WLAN connection will be established.
Your guest’s WLAN device can use the Internet connection of
the FRITZ!Box, but has no access to your home network. For
more information, see the Online Help.

Switching the WLAN Radio Network On and Off by Schedule
11.3 Switching the WLAN Radio Network On and Off by Schedule
You can switch the WLAN radio network of the FRITZ!Box automatically according to a schedule. This function is called
“night service” and reduces the power consumption of the
FRITZ!Box by completely turning off the WLAN module. The
FRITZ!Box Night Service also affects any other FRITZ! products
connected in the network (FRITZ!WLAN Repeater, for instance)
by switching the WLAN transmission of these devices on and
off as well.
1. Open the FRITZ!Box user interface.
2. Open the “System / Night Service” menu.
3. Enable the schedule for the WLAN radio network.
With the options “Switch WLAN off daily” and “Switch
WLAN off according to schedule” you define the intervals of the schedule. You can also select the option “The
radio network cannot be switched off until no more
WLAN devices are active”.
For more information on these settings, see the Online Help.
Switching WLAN On and Off Manually
You can switch the wireless radio network of the FRITZ!Box on
and off at any time, even when the device is hibernating.
• Press the WLAN button on the FRITZ!Box briefly
11.4 Enlarging the WLAN Radio Network
The range of a WLAN radio network is not specified. It depends on
• the WLAN devices you are using for your WLAN connec-
tions
• interference in the vicinity of your WLAN radio network
• the structural conditions where you operate the WLAN
radio network
• the number of WLAN devices in the vicinity of your
FRITZ!Box that work in the same frequency range
FRITZ!Box 3370 58
Enlarging the WLAN Radio Network
You can extend the range of your WLAN radio network with a
WLAN repeater.
Or you can set up a second WLAN router, for instance a second FRITZ!Box as a WDS repeater.
Expanding a WLAN Radio Network with a WLAN
Repeater
You can expanding your WLAN radio network with a WLAN Repeater. In combination with the FRITZ!Box the AVM
FRITZ!WLAN Repeater are especially suitable. All models of
the FRITZ!WLAN Repeater series can be integrated into your
WLAN radio network and your home network by WPS Quick
Connection. Find out more in the Internet at:
www.avm.de/en/Produkte/FRITZ_WLAN/FRITZ_WLAN_
Repeater_N_G
Expanding a WLAN Radio Network with a WDS Repeater
You can expand the WLAN radio network of your FRITZ!Box
with what is called a WDS repeater. A WDS repeater can be a
FRITZ!Box or any WLAN router you already have that can be
configured as a WDS repeater to expand your WLAN radio network.
See the documentation of your device to find out whether
your existing WLAN router supports the WDS function and
how to configure it as a WDS repeater. Your FRITZ!Box or another FRITZ!Box model can be configured as a WDS repeater
by working through the following steps:
1. Open the FRITZ!Box user interface.
2. Select “View: Advanced”.
3. Select the “WLAN / WDS” menu and follow the instruc-
tions displayed on the screen.
See the Online Help of the FRITZ!Box for more information.
FRITZ!Box 3370 59
WLAN—Getting Technical
The wireless LAN connection between your FRITZ!Box and a
FRITZ!Box in WDS operation can be encrypted by WPA2. The
wireless LAN connection between your FRITZ!Box and another wireless LAN router is only possible with less secure WEP
encryption.
11.5 WLAN—Getting Technical
A wireless LAN radio network is based on standards defined
by the Institute of Electrical and Electronic Engineers (IEEE).
These standards describe, for instance, the transmission
speeds, encryption methods and frequencies used in a wireless LAN network.
WLAN Standards
The Institute of Electrical and Electronic Engineers (IEEE) defined the WLAN standards IEEE 802.11a, IEEE 802.11b, IEEE
802.11g, IEEE 802.11n and IEEE 802.11i for WLAN radio networks.
Standards for the Throughput Rate
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.
Standard Frequency Band Gross Data Throughput up toNet Data Throughput up to
802.11b 2.4 GHz 11 Mbit/s 5 Mbit/s
802.11g 2.4 GHz 54 Mbit/s 25 Mbit/s
802.11a 5 GHz 54 Mbit/s 25 Mbit/s
802.11n 2.4 / 5 GHz 450 Mbit/s 200 Mbit/s
The standards are intended for different frequency bands.
FRITZ!Box 3370 60
WLAN—Getting Technical
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.
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.
FRITZ!Box 3370 61
WLAN—Getting Technical
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. Enable the advanced view.
3. Open the “WLAN / Radio Channel” menu and select “Ad-

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
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.
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.
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 of up
to 216 Mbit/s) or 40 MHz (throughput of up to 450 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,
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 from Other
Wireless Networks from page 101.
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
FRITZ!Box 3370 65
WLAN—Getting Technical
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 101.
A prerequisite for use of the 5-GHz frequency band is that
WLAN devices used in the network support this frequency
range in accordance with the IEEE 802.11a or IEEE 8002.11n
standard.
2.4 GHz or 5 GHz
The FRITZ!Box works in the wireless network either in the
2.4-GHz 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. If this is not possible due to interference or channels already being used by
other WLANs in the vicinity, the FRITZ!Box automatically
switches temporarily to a bandwidth of 20 MHz. Greater
bandwidth provides for higher data throughput:
Bandwidth (MHz) Maximum Data Throughput (Mbit/s)
20 216
40 450
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.

Network Settings in the FRITZ!Box
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.
Starting the Computer—Wake on LAN
The Wake on LAN function of computers can be enabled in the
editing mode for network devices. The computers must support wake on LAN and be connected with the FRITZ!Box with a
network cable. The wake on LAN function is also available
when the devices are connected via FRITZ!Powerline devices.
Wake on LAN is a function that allows a computer in the local
network to be started when it is accessed from the Internet.
For instance, you can access a computer using remote maintenance software, without wasting electricity by keeping the
computer switched on permanently. The computer must be in
standby operation.
The FRITZ!Box supports Wake on LAN both for IPv4 and for
IPv6 connections.
• The “Start Computer” Button
You can start the computer each time it is accessed over
the Internet by clicking the “Start Computer” button.

If you would like to change the IPv4 address, please read
through the following sections.
When Does It Make Sense to Change the IPv4 Address?
You should change the IPv4 address of the FRITZ!Box if the
following apply to your network:
• You have an existing local IPv4 network, one subnet with
several computers.
• Fixed IPv4 addresses are registered in the network set-
tings 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 IPv4 net-
work in order to make the FRITZ!Box features available to
all of the computers in the IPv4 network.
Reserved IP Addresses
The entire IP network 192.168.180.0 in the FRITZ!Box is reserved for internal purposes.
IPv4 addresses from this network may not be assigned to the
FRITZ!Box.
DHCP Server for IPv4
The FRITZ!Box is equipped with its own DHCP server for the
IPv4 network. 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 IPv4
address from the IP address range of the DHCP server.
FRITZ!Box 3370 74
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 IPv4 addresses from the
DHCP server only if the setting “Obtain an IPv4 address automatically” is enabled in the their IP settings. For more information, see the section Obtaining an IP Address Automati-
cally from page 78.
Fixed IPv4 Addresses When the DHCP Server Is Enabled
If you would like to configure fixed IPv4 addresses on individual computers connected with the FRITZ!Box despite the enabled DHCP server, please note the following:
• The IPv4 addresses must be from the IPv4 network of the
FRITZ!Box.
• The IPv4 addresses may not come from the address
range of the DHCP server.
• Each IPv4 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
IPv4 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 IPv4 address of the FRITZ!Box, the
following IPv4 addresses are available for assignment to the
computers:
192.168.178.2 - 192.168.178.254
FRITZ!Box 3370 75
Network Settings in the FRITZ!Box
Here too: each IPv4 address can be assigned only once.
Changing Network Settings
1. Enable the advanced view in the user interface.
2. Select the “Home Network / Network” menu.
3. Select the “Network Settings” page.
4. Click the “IPv4 Addresses” or “IPv6 Addresses” button,
depending on the address range you would like to
change.
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.
IPv6 Settings in the FRITZ!Box
The following settings options for IPv6 are found in the advanced view in the “Home Network / Network” menu on the
“Network Settings” page.
Additional IPv6 Routers in the Home Network
• IPv6 prefixes from other IPv6 routers
You can allow the network devices connected to the
FRITZ!Box to receive IPv6 prefixes announced by other
IPv6 routers in the local network.
• Also announce DNSv6 server via router advertisement
With this setting you specify that the FRITZ!Box announces the local DNSv6 server in the local network via router
advertisement. Alternatively, the network devices can
identify the local DNSv6 server via DHCPv6.
IPv6 Settings
Click the “IPv6 Addresses” button to configure settings for
the IPv6 addresses in the local network.
FRITZ!Box 3370 76
Network Settings in the FRITZ!Box
Unique Local Adresses
The communication within the local network takes place via
the Unique Local Addresses (ULA). If no IPv6 Internet connection is established, the network devices do not have a ULA
and communication between them is restricted. For this case
you can set the FRITZ!Box such that the network devices receive the ULA from the FRITZ!Box.
DHCPv6 Servers in the Home Network
The FRITZ!Box is equipped with its own DHCPv6 server. The
DHCPv6 server of the FRITZ!Box is switched on by default.
The DHCPv6 server assigns the network devices their IPv6
settings. These settings are used instead of the data in the
router advertisement messages. The DNS server, IPv6 prefixes or IPv6 addresses can all be assigned by DHCPv6. Define
which IPv6 settings should be assigned by the DHCPv6 server.
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 26).
2. Enable the advanced view.
3. Configure the UPnP settings in the “Home Network / Net-
work” menu on the “Programs” page.
Guest Access over the LAN 4
The network port “LAN 4” can be configured as a guest access. Guests can then connect their laptops to the guest access with a network cable to access the Internet. The guest
device does not have access to the home network.

The FRITZ!Box has two USB ports 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.
14.1 Power Supply for USB Devices
You can connect USB devices with the following properties to
the FRITZ!Box:
• Some USB devices require more than one USB port for
operation, 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.
14.2 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
EXT2 and NTFS file systems 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 84).
• 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 81).
• 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 20).
14.3 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 storage 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.
14.4 Configuring Password Protection and Access Rights
To protect the data on your USB memory from unauthorized
access, you can set up a password and access rights. Both
the password protection and the access rights are valid on all
memory available in the FRITZ!Box home network. You can
not assign special passwords or access rights for individual
storage media.
FRITZ!Box 3370 82
Accessing USB Memory
1. Start a web browser.
2. Enter “fritz.box” in the address line.
3. Go to the “Home Network / Storage (NAS)” and select
the “Security” tab.
4. Configure the access rights and password protection.
Note that you cannot set up password protection and access
rights if the USB remote connection is active.
14.5 Accessing USB Memory
The participants in the home network have various possibilities for accessing the various storage media of the FRITZ!Box.
• Home network members can access the contents of con-
nected USB memory and all other memory of the
FRITZ!Box especially conveniently with FRITZ!NAS. For
this FRITZ!NAS offers a graphic interface and allows data
exchange by drag & drop.
• 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 storage media
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 or on storage media of the
FRITZ!Box you can enable the FRITZ!Box media server.

Sharing a USB Printer
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. The term
“DLNA” is often used to designate this support.
Enable the “media server” function in the FRITZ!Box user
interface under “Home Network / Storage (NAS) / Options Enabled”.
14.6 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.
Using a USB Printer as a Network Printer
Configure the USB printer as a network printer on the
FRITZ!Box if
• the participants in the home network are to be able to
use the printer jointly and simultaneously.
• the printer is to be used by computers that use an oper-
ating system other than Windows (e.g. Mac OS X or
Linux).
For information about how to configure a USB printer as a network printer, see the section Setting Up a USB Printer as a
Network Printer on page 85.
Using a USB Printer with FRITZ!Box USB Remote Connection

Saving Energy with FRITZ!Box
15 Saving Energy with FRITZ!Box
The FRITZ!Box combines a variety of devices in one device: VDSL and
ADSL modem, WLAN router and media server. This means that you generally use much less power with the FRITZ!Box than you would with several separate devices.
What is more, the FRITZ!Box saves energy by reducing processing power
on standby and lowering the power consumption of idle functions. The
FRITZ!Box also offers various settings for energy-saving operation.
The current energy consumption of the total FRITZ!Box system is displayed on the “Overview” page. From there, click
with the mouse to view the Energy Monitor, which displays
details on the energy consumption.
15.1 Saving Energy with the WLAN Radio Network
You can reduce the power consumption of the WLAN radio
network by
• setting up night service for the WLAN radio network (see
page 58).
• turning off the WLAN radio network with the “WLAN” but-
ton whenever no more WLAN devices are registered on
the FRITZ!Box.
• adjusting the setting “Maximum transmitter power” to
the percentage level actually needed. This setting is configured in the “WLAN / Radio Channel” menu in the
FRITZ!Box user interface.
15.2 Enabling Energy-saving Mode for USB Hard Drives
In the FRITZ!Box you can enable an energy-saving function for
USB hard drives connected to the FRITZ!Box.
When the energy-saving function is enabled, connected USB
hard drives will be switched off when they are idle—as long
as the hard drives support the energy-saving function.
FRITZ!Box 3370 90
Saving Energy at the LAN Ports
Enable the energy-saving function in the “Home Network /
USB Devices” menu in the FRITZ!Box user interface. You can
also test here, wether your USB hard disk supports the energy-saving function.
15.3 Saving Energy at the LAN Ports
For the individual LAN ports of your FRITZ!Box you can configure various operation modes. The power consumption of
some modes is higher than others. Select the operation
mode that is best suited to your needs in order to minimize
the power consumption of the LAN ports.
The LAN ports can be configured in the FRITZ!Box user interface. In the “System / Energy Monitor” menu, the following
operating modes are available on the “Settings” page:
Operating Mode Functionality and Power Consumption
Always Enabled The LAN port is always enabled.
Highest power consumption.
Enable Automatically – Power Mode

Help in Case of Errors
16 Help in Case of Errors
This chapter provides assistance if you are not able to open
the user interface of your FRITZ!Box or are having problems
with the DSL or WLAN connection.
16.1 Cannot Establish a DSL Connection
The FRITZ!Box automatically establishes a connection to the
DSL network as soon as it is connected with the DSL line. If

error.
Changing the Annex Setting of the FRITZ!Box
The FRITZ!Box cannot establish a connection to the DSL
network. This is signaled by the continued flashing of the
“Power” LED.
Cause
The kind of DSL (Annex A, B, J or M) set in the FRITZ!Box is not
the same as the annex used on your DSL line.
Help
1. Contact your Internet service provider to find out which
annex is used on your DSL line.
2. Connect a computer with the FRITZ!Box either wirelessly
via WLAN or using a network cable.
