Increasing the WLAN Range
The range of a WLAN radio network also always depends
on external influences. The following factors have an es-
pecially strong influence on the distance over which your
FRITZ!Box can establish a stable, high-throughput wire-
less connection:
the WLAN adapter used
structural conditions at your location
the number of devices operating near the access
point in the same frequency range
You can extend the range in your wireless network yourself
as needed. To do so you will need supplementary equip-
ment not included in your FRITZ!Box package: You can ei-
ther use a WLAN repeater, for instance the
FRITZ!WLAN Repeater by AVM, or use an additional WLAN
access point working in repeater mode to set up a wireless
distribution system. Both options are described in greater
detail below.

Using the FRITZ!WLAN Repeater N/G
Using the FRITZ!WLAN Repeater N/G
To increase the WLAN range, especially under difficult or
strongly-shielding structural conditions, the
FRITZ!WLAN Repeater N/G, available as an accessory from
AVM, can be used in combination with the FRITZ!Box. It
supports all common WLAN standards, is especially easy
to install and can be operated at any 230-V power outlet.
Setting up a WDS
To extend the range in your wireless network using WDS
(Wireless Distribution System), you will need a WLAN ac-
cess point in addition to the FRITZ!Box. One of the two
WLAN access points works as the WDS base station, the
other 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 would be located beyond its range without
the WDS repeater.
WDS: Expanding the WLAN range using a repeater
Note the following for WDS configuration:
In order to expand the range of your wireless net-
work, you need at least one additional WLAN access
point. The wireless network of your FRITZ!Box can be
expanded to a WDS (Wireless Distribution System)
with up to three WLAN access points.
All WLAN access points implemented in the WDS
must support WDS and be configured for this tech-
nology.
All WLAN access points implemented as repeaters in
the WDS must be located within the radio range of
the WDS base station.

Setting up a WDS

The FRITZ!Box can function as a WDS base station to
establish the Internet connection for other WDS re-
peaters, or as a WDS repeater to expand the range of
a WDS base station.
Make sure that the WDS connections between the
WDS base station and the WDS repeaters are secured
using the same encryption (for instance,
WPA/WPA2). Note that the WPA2 encryption method
is available only when your network consists of AVM
devices, since only WEP encryption has been speci-
fied for WDS connections among all manufacturers.
Make sure that all WLAN access points in the WDS
use the same radio channel.
Every access point participating in the WDS fulfills
the tasks of a WLAN access point for its given WLAN
clients. This means that the WLAN clients see each
WLAN access point 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
with Service Pack 2 on your WLAN clients, you can as-
sign the same SSID and the same encryption settings
to different WLAN access points. Each client can then
automatically register at the WLAN access point with
the best availability.
Make sure that each IP address is assigned only once
in the wireless network.
Configuring FRITZ!Box as a Base Station
WDS Base Station
As a
WDS base station
, the FRITZ!Box establishes Internet
connections for other WLAN repeaters and WLAN clients.
For instructions on how to set up the FRITZ!Box as a WDS
repeater, start reading from page 140.
To set up the FRITZ!Box as a WDS base station, proceed
according to the following directions:
1.
Start a web browser.

Setting up a WDS
2.
Enter
fritz.box
in the address field.
The FRITZ!Box user interface opens.
3.
Make sure that the expert setting is enabled in the
“System / Expert Mode” menu and click “Apply”.
4.
Open the “WLAN / Radio Network” menu.
5.
If the wireless network (WLAN) is not enabled yet, en-
able the setting “WLAN radio network active” and
then click “Apply”.
6.
Click the “WDS” menu entry.
7.
Enable the “WDS enabled” setting.
8.
Select “Base station” as the operating mode.
9.
Select from the list of “WLAN Devices” the devices
that are to be used as WDS repeaters.
10.
In the “Security” area define how the WDS repeater
connection should be encrypted.
11.
Enter a WLAN key.
12.
Click “Apply”.
The “Repeater Settings” you require to set up the
WDS repeaters are displayed.
13.
We recommend printing out these settings.
This concludes the configuration of the FRITZ!Box as a
WDS base station.
Note that the WPA2 encryption method is available
only when your network consists of AVM devices.
Register the FRITZ!Box settings you printed out in each
WDS repeater operating in your wireless network.

6.
Click the “WDS” menu command.
7.
Enable the “WDS enabled” setting.
8.
Select the “Repeater” option as the operating mode.
9.

If the FRITZ!Box is to be operated as a WDS repeater,
you must change its IP settings.
IP address:
Enter here an IP address for this
FRITZ!Box that fulfills the following criteria: The IP
address must be different from the IP address of
the WDS base station, and must come from the IP
network of the WDS base station. Keep in mind
that the IP address may not come from the ad-
dress range of the DHCP server of the WDS base
station.
