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.
9
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.

Establishing a WLAN Connection with AVM Stick & Surf
If you use a FRITZ!WLAN USB Stick from AVM as the WLAN device, you can use AVM Stick & Surf to establish a secure
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.

device is also equipped with a WPS button, or if WPS can be
enabled via the control software of the WLAN device.
1. Press the “WLAN” button on the FRITZ!Box and hold it
down for at least six seconds.
2. As soon as the “WLAN” LED begins flashing, enable the
WPS function on the other WLAN device, either by pressing a button or in the device’s user interface (depending
on the device). Activation must be started within
two minutes.
The FRITZ!Box and the WLAN device now connect with each
other automatically. The WLAN device adopts the security settings of the FRITZ!Box.

WPS with the PIN Method
If your WLAN device supports WPS, but does not have a button to start the push method nor any possibility to enable it in
its control software, use the PIN method to establish the
WLAN connection.
You can choose between two methods:
• the FRITZ!Box specifies the PIN
• the WLAN device specifies the PIN.
The FRITZ!Box Specifies the PIN
1. Open the FRITZ!Box user interface.
2. Select the “WLAN / Security” menu.
3. Go to the “WPS / Quick Connection”page.
4. Enable the setting “WPS enabled”.
5. Select the option “PIN method (WPS-PIN), the FRITZ!Box
specifies the PIN”.
6. The PIN will be displayed. Enter this PIN in the control
software of the WLAN device.
7. Click “Start WPS”.
The “WLAN” LED on the FRITZ!Box flashes slowly, indicating
that the WPS procedure has begun. Now a secure WLAN connection is being established between the FRITZ!Box and the

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.
28
Connecting Computers Wirelessly over WLAN
