FRITZ!WLAN Repeater N/G 22
Microsoft WLAN Service (WZC) Is Not Supported
Set the SSID to “visible” (announced).
For registration with the WPS function the SSID must be visible.
After successful registration you can hide the SSID of the access
point again.
6.5 Microsoft WLAN Service (WZC) Is Not Supported
The WLAN connection to the FRITZ!WLAN Repeater cannot be
established using the Microsoft WLAN Service (WZC) in
Windows XP with Service Pack 2.
Possible Cause
The required Microsoft patch for WPA2 (IEEE 802.11i) may not
be not installed.
Remedy
Install the current patch for Microsoft Windows XP with Service
Pack 2 from the web page
http://support.microsoft.com/kb/91702/EN-US or install Ser-
vice Pack 3.
6.6 No Higher Data Rates Available
Higher data rates in accordance with the WLAN standard
IEEE 802.11n are not available on one of the WLAN clients
connected to the FRITZ!WLAN Repeater (e.g., your notebook).
Possible Cause
The connection between the FRITZ!WLAN Repeater and the
WLAN base station or between the FRITZ!WLAN Repeater and the
WLAN client is not encrypted using WPA2. The use of the
IEEE 802.11n standard—and thus the availability of higher
throughput rates—is possible only if the WLAN connection is secured using the WPA2 (AES-CCMP) security mechanism.
Remedy
Set the WLAN encryption of the FRITZ!WLAN Repeater and the
encryption of the WLAN base station to WPA2. It is also possible
to achieve the data throughput rates of the 802.11n standard if
all WLAN participants transmit wirelessly. Because of the security risk associated with an open wireless network, we expressly
advise against using this option!
FRITZ!WLAN Repeater N/G 23
Interference During Audio Output
6.7 Interference During Audio Output

More about WLAN
2 More about WLAN
AVM and WLAN
WLAN (Wireless Local Area Network) is a radio technology that allows
networks access to the Internet to be provided without cable connections. This allows multiple users to share one wireless Internet connection.
2.1 Standards
The WLAN standards IEEE 802.11a, IEEE 802.11b,
IEEE 802.11g and IEEE 802.11n (on the basis of the preliminary draft 2.0 of the standard) and IEEE 802.11i were
developed by the Institute of Electrical and Electronic Engineers (IEEE).
The standards IEEE 802.11a, IEEE 802.11b, IEEE 802.11g
and IEEE 802.11n define the transmission rate within a
wireless LAN. The IEEE 802.11i standard is a security standard.
Standards for the Throughput Rate
Data Throughput The FRITZ!WLAN Repeater supports the IEEE 802.11n wire-
less standard and is downward compatible to 802.11a, b
and g networks.
The standards are intended for different frequency bands.
Standard Frequency Band Gross Data Throughput up to Net Data Throughput up to
802.11a 5 GHz 54 Mbit/s 54 Mbit/s
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 100 Mbit/s
The throughputs listed differentiate between gross and
net transmission rates. The net speed describes the transmission rate of the user data.
The standard used in a given WLAN depends on the settings of the WLAN access point.
29
Standards for the Throughput Rate
In order to communicate with each other, the
FRITZ!WLAN Repeater and the WLAN access point must
work in the same frequency band.
Range The range within a WLAN is highly dependent on the fol-
lowing factors:
the WLAN adapter used
the structural conditions
the amount of radio traffic on the same frequency
band. Other WLAN networks, microwave ovens or
Bluetooth transmitters (mobile telephones) may be
active.
where the FRITZ!WLAN Repeater is positioned
The FRITZ!WLAN Repeater provides for optimum extension of your wireless network when it is positioned halfway between your access point and the
devices for which the wireless network is to be extended. The device should also be operated in a location as central and free of obstruction as possible,
e.g. not in a closet, cabinet or below a radiator.
IEEE 802.11a This standard communicates with a maximum of
54 Mbit/s and works exclusively in the seldom used 5GHz range. This means it offers the opportunity to transmit
data relatively free of interference from external influences.
IEEE 802.11b With a maximum throughput rate of 11 Mbit/s, this is the
oldest standard for radio networks. Older WLAN access
points of the first generation can communicate with the
FRITZ!WLAN Repeater using 802.11b. However, if the
WLAN access point 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 com-
municates with a maximum of 54 Mbit/s gross in the 2.4GHz frequency range (ISM) and guarantees broad compatibility with many WLAN devices.
30
The Standard for Security
IEEE 802.11n This standard allows for high throughput rates and rang-
es. The FRITZ!WLAN Repeater supports 802.11n in the 2.4GHz frequency band, or, if desired, also in the 5-GHz frequency band. Modulation processes and antenna techniques like MIMO (Multiple Input, Multiple Output) use
the entire frequency band 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 (AES-CCMP).
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
AES-CCMP encryption process.
Mechanism Encryption
WPA TKIP (Temporary Key Integrity Protocol)
WPA2 TKIP
AES-CCMP
based on the extremely secure AES (Advanced Encryption Standard) procedure.
CCM (Counter with CBC-MAC) defines how
the AES procedure is applied to WLAN
packets.
The FRITZ!WLAN Repeater 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!WLAN Repeater can be used in combination with any WLAN adapters that also support WPA2
with AES or WPA with TKIP.
31
Security
2.2 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.
This is why the FRITZ!WLAN Repeater adopts the security
settings of your FRITZ!Box when it establishes a connection using WPS. For radio networks set up manually, these
security settings must be configured in the user interfaces
of the devices.
Encryption
The most important security setting is encryption. The
FRITZ!WLAN Repeater supports the security mechanisms
WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access) and WPA2 as follows:
As part of the WEP mechanism a static key is deter-
mined to serve for the encryption of the user data.
WLAN Radio Network Name (SSID)
In the factory settings of the FRITZ!WLAN Repeater a value
of “FRITZ!WLAN Repeater N/G” is preset as the default value of the SSID (Service Set Identifier). As soon as the initial configuration has been completed, the
FRITZ!WLAN Repeater automatically takes on the network
name of your WLAN base station. Depending on the WLAN
client used and how accessible it is, the network name of
the base station and the repeater will be listed once or
multiple times in the WLAN software. If you want to be
able to distinguish the FRITZ!WLAN Repeater from the
base station, you can change the network name of the
FRITZ!WLAN Repeater.
32
Frequency Ranges
2.3 Frequency Ranges
WLAN uses the frequency range around 2.4 GHz in the ISM
band or, alternatively, the frequency range at 5 GHz.
In order to communicate with each other, the
FRITZ!WLAN Repeater and the WLAN access point must
work in the same frequency band.
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 some cordless telephones, 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 the only adverse effects
are to the transmission rate; aborted connections and data losses are rare.
WLAN in the 5-GHz frequency band is subject to less interference, as these radio frequencies are used much less often.
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 2.4GHz 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.
If your WLAN access point is equipped with an autochannel function, you can automatically have it search for a
WLAN channel in your frequency range that is subject to as
little interference as possible.
33
Frequency Ranges
5-GHz Frequency
Band
The FRITZ!WLAN Repeater can operate in the 5-GHz frequency band as an alternative. This frequency range is
used much less frequently than the most common 2.4GHz frequency range.
A prerequisite for use of the 5-GHz frequency band is that
all WLAN adapters in the network support this frequency
range in accordance with the IEEE 802.11a or
IEEE 8002.11n standard.
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!WLAN Repeater
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 channels already being used by other WLANs in the vicinity, the FRITZ!WLAN Repeater automatically switches over 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.

ADSL abbreviation for Asymmetric Digital Subscriber Line
designates a fast kind of file transfer that works with standard copper cables and transports signals in both directions at different speeds (upstream at 640 Kbit/s and
downstream at up to 9 Mbit/s).
ADSL2 abbreviation for Asymmetric Digital Subscriber Line 2
ADSL2 (G.992.3) is a further development of the ADSL
norm G.992.1/G.992.2).
ADSL2 offers range much greater than did the first ADSL
generation, and is significantly more robust than ADSL, as
it can simply disable single carrier frequencies when they
produce interference. This feature allows ADSL2 to prevent synchronization losses.
With a throughput rate of up to 12 Mbit/s downstream,
ADSL2 offers considerably greater bandwidth than ADSL.
ADSL2 is completely downward compatible, meaning that
terminal equipment compliant with ADSL can also be operated on ADSL2 lines, although they cannot exploit the
advantages of ADSL2.
ADSL2+ abbreviation for extended bandwidth Asymmetric Digital
Subscriber Line 2
ADSL2+ (G.992.5) is a further development of the ADSL
norm (G.992.1/ G.992.2).
ADSL2+ offers a doubled frequency range used for downstream transmission, and thus double the maximum
bandwidth achievable for downstream to 24 Mbit/s.
ADSL2+ is completely downward compatible, meaning
that terminal equipment compliant with ADSL and ADSL2
can also be operated on ADSL2+ lines, although they cannot exploit the advantages of ADSL2+.

Default Gateway see gateway
DHCP abbreviation for Dynamic Host Configuration Protocol
DHCP is a protocol for the dynamic negotiation of the operating parameters for the TCP/IP protocol (TCP is a transport protocol based on the Internet protocol).
The computers of a local IP network (DHCP clients) access
the DHCP server as part of their operating systems’ start
procedure.
The central administration of the TCP/IP operation parameters makes it possible to avoid address conflicts caused
by IP addresses accidentally assigned more than once.
DHCP Server The DHCP server assigns each client an IP address that is
has not yet been assigned at the present time. The DHCP
server also informs the client of the IP addresses of the
DNS server to be used and of the default gateway. In assigning the IP addresses the DHCP server selects from a
prescribed pool of IP addresses.
DNS abbreviation for Domain Name System
Domain Name Service takes care of determining the IP address for a given domain name. This Domain Name Service runs on every computer. It accepts the domain name
FRITZ!WLAN Repeater N/G 41
Glossary
entered by a user and inquires about the corresponding IP
address at a DNS server known to the service. If a DNS
server cannot answer the inquiry itself, it can inquire
about the IP address (DNS resolution) at other DNS servers.
If the Domain Name Service receives negative information
from the DNS server (domain name not known), it can
send inquiries to other DNS servers it knows or return a
corresponding error message to the user. If it receives the
desired IP address instead, the application can use the IP
address to retrieve the destination desired by the user.
This hierarchical system of DNS servers is known as the
Domain Name System. The addresses of the DNS servers
at which the Domain Name Service is to inquire by default
generally are handed over to the computer by the Internet
Service Provider automatically whenever a connection to
the Internet is established. In local networks addresses
can also be assigned via DHCP. Otherwise they must be
entered manually in the TCP/IP settings of the computer
by the user or the system administrator.
DSL Modem A DSL modem connects a computer to the Internet via the
DSL line. In contrast to the analog modem, a connection
via the DSL modem does not mean that the telephone line
is busy.
DSL Router A combination of a DSL modem and a router is called a
DSL router.
Dynamic DNS abbreviation for Dynamic Domain Name System
Dynamic DNS is a service which allows a computer always
to be reached under the same domain name despite constantly changing IP addresses. This means that even private users have an economical way of placing their own
Internet offers on their computer at home.
It works by transmitting the current IP address to a special
DDNS server each time the IP address changes. Except for
the few seconds between the cancellation of the old IP ad-
FRITZ!WLAN Repeater N/G 42
Glossary
dress and the notification of the new IP address, the computer can always be reached at the selected domain
name.
Dynamic IP
Address
A dynamic IP address is an IP address valid only for the
duration of one Internet or network session.
Every computer participating in the Internet must have a
uniquely assigned public IP address. Since only a limited
number of such IP addresses is available, they must be
used sparingly. That is why most of the Internet participants who dial in to the Internet receive a dynamic IP address. They are called dynamic because every participant
receives a new public address that has not been assigned
yet each time she or he dials in to the Internet.
By contrast, dynamic addresses are usually used in local
IP networks because they are easy to handle, and because
using them avoids incorrect IP address entries or unintentional double assignments. The DHCP service is responsible for assigning unique dynamic IP addresses.
FAQ abbreviation for Frequently Asked Questions
FAQs are collections with answers to frequently asked
questions on a certain subject area.
Fixed IP address Fixed IP addresses are IP addresses which are permanent-
ly assigned to a computer or another device like a network
printer.
Assigning fixed IP addresses makes sense in cases where
a local network has a sufficiently large pool of IP addresses available, or when a computer is always supposed to
be accessible at a certain address (such as a web server or
e-mail server).
Firewall A firewall protects a computer or local network against at-
tacks from the Internet.
Most firewalls work with packet filters, which merely
check the IP addresses and port numbers of incoming and
outgoing data packets and filter the packets according to
prescribed rules.
FRITZ!WLAN Repeater N/G 43
Glossary
Some firewalls also integrate additional concepts like IP
masquerading and NAT to decouple data traffic by distinguishing strictly between the internal and external network.
Especially effective firewalls go even further, analyzing
and evaluating the contents of the packets and filtering
them according to prescribed rules. Such techniques may
also include a Stateful Packet Inspection Firewall, for instance.
Firmware The firmware is saved in programmable components with-
in a device. Through the possibility of updating the firmware by computer at any time, manufacturers enjoy great
flexibility in reacting to the demands of the operational
environment, integrating new functions requested by customers, and eliminating errors discovered after production.
FTP abbreviation for File Transfer Protocol
The File Transfer Protocol allows files to be exchanged between two computers operating in the Internet. Data exchange takes place via an FTP server and what is known as
an FTP client. The more convenient FTP clients are available as stand-alone software or are components of some
ISDN data transfer software; simple FTP clients are now included in many web browsers.
Gateway Gateway is a general term designating an interface be-
tween two computer networks. Such a network interface
can be realized using a router or a bridge, for instance.
If a computer wants to transfer data packets to a computer
in another network, it must first transmit the packet to the
gateway. To do this, the computer must know the address
of the gateway.
If all packets that cannot be delivered in a local network
always are to be transmitted to their given recipients via
the same gateway, for this purpose the address of the
gateway must be saved as the default gateway in the network settings of the computer.
FRITZ!WLAN Repeater N/G 44
Glossary
Such a default gateway for the computer is negotiated automatically by the operating system or the dialing software whenever an ISDN-Controller or DSL-Controller establishes a connection to the Internet. If a router is used for
the shared Internet access in a local network, the IP address of the router must be entered as the default gateway
in the TCP/IP settings of each computer that wishes to use
the Internet connection. If the TCP/IP setting is configured
by means of a DHCP server, there is no need to enter the
gateway address manually.
IP abbreviation for Internet Protocol
The IP Internet Protocol is the most important basic protocol for the control of data exchange in local networks and
in the Internet. The Internet protocol works without a connection; in other words, data packets are transmitted from
the sender to the recipient without previous consultation.
The addresses of the recipient and the sender in the data
packets are given as IP addresses.
IP Address abbreviation for Internet Protocol address
In IP-based networks, for instance in the Internet and local
networks, all connected devices are addressed via their IP
addresses. So that data packets are sure to be delivered
to the right address, each IP address may be assigned only once within the Internet or a local IP network.
The IP address consists of four three-digit groups of numbers (for instance, 192.168.178.247). Each group of numbers can assume values between 000 and 255.
Every IP address contains two components: the network
address and the host address. These two components can
be read out of an IP address only if the subnet mask is also specified.
IP addresses can be public or private, and also fixed or assigned dynamically. See the corresponding entries in the
Glossary for more information.
FRITZ!WLAN Repeater N/G 45
Glossary
IP Addressing Addressing is one of the main functions of the Internet
Protocol (IP). Internet addresses can be written in decimal, octal or hexadecimal notation. The
FRITZ!WLAN Repeater uses “dotted-decimal” notation:
The four bytes of an address are represented by decimal
numbers separated by dots. The total volume of Internet
addresses, the address space, is separated into classes
(A, B, C, D, and E). The full set of IP addresses, called the
address space, is grouped into address classes designated as A, B, C, D and E. Only the first three of these five address classes are actually used. These classes can be described as follows:
Classes Properties Network address
Decimal value
Class A address
Class B address
Class C address
Few networks, many hubs 0-127
Intermediate distribution of
networks and hubs
Many networks, few hubs 192-223
128-191
Properties of IP Address Classes
Every IP address consists of two parts: the network address and the host address. The sizes of the network address and the host address are variable, and determined
by the first four bits (of the first byte) of the IP address.

By means of IP masquerading a computer or LAN can be
Masquerading
protected from unauthorized connection request from the
Internet. Masquerading works by converting the IP addresses used in a network to one public IP address. From
the outside it appears that all requests are sent from a single computer.
IP Network A network in which data exchange takes place on the ba-
sis of the Internet Protocol is called an IP network.

Public IP
Address
A public IP address is an IP address valid in the Internet.
Every computer or router participating in the Internet must
have a uniquely assigned public IP address. This address
is usually negotiated dynamically with the Internet Service
Provider when a connection to the Internet is dialed. The
Internet Service Provider assigns the negotiated IP address to the computer or router for the duration of an Internet session.
Private IP
Address
Private IP addresses are used for computers and other
network devices within local IP networks.
Since many local IP networks are not connected to the Internet except via single computers or routers (gateway),
certain address ranges are excluded from the publicly
available IP addresses so that they are available for assignment in local IP networks. An IP address may only be
assigned once within the local network. A private IP address may exist in any number of other local networks.
Subnetwork A local IP network can consist of one subnetwork or be di-
vided into multiple subnetworks. The division into subnetworks is performed when the local IP network is configured. The subnetworks of a local IP network are also IP
networks.
Subnet Mask The subnet mask indicates which part of an IP address is
the network address and which the address of the computer. The network address defines what is called the subnet.
Example 1
IP address: 192.168.178.247
Subnet mask: 255.255.255.0
The assignment of the first three groups of numerals in the subnet mask indicates that the first three groups of numerals in the
IP address define the network. The following addresses result:

Example 1
Network address of the subnet: 192.168.178.0
Address of the computer in the
subnet:
IP address pool in the subnet: 192.168.178.0 -
Example 2
IP address: 192.168.178.247
Subnet mask: 255.255.0.0
The assignment of the first two groups of numerals in the subnet mask indicates that the first two groups of numerals in the
IP address define the network. The following addresses result:
Network address of the subnet: 192.168.0.0
Address of the computer in the
subnet:
IP address pool in the subnet: 192.168.0.0 -
192.168.178.247
192.168.178.255
The IP addresses
192.168.178.0 and
192.168.178.255 are reserved. This means that the
addresses from
192.168.178.1 to
192.168.178.254 are available for assignment to the
computers. Therefore a maximum of 254 computers can be
included in the subnetwork
192.168.178.247
192.168.255.255
That’s 65,536 IP addresses.
The IP addresses 192.168.0.0
and 192.168.255.255 are reserved. This means that the
addresses from 192.168.0.1 to
192.168.255.254 are available for assignment to the
computers.

Glossary
TCP/IP abbreviation for Transmission Control Protocol / Internet
Protocol
TCP/IP is the “language” of the Internet. TCP/IP is used to
refer to a suite of protocols used for data communication
over the Internet. TCP and IP are the network and transport
protocols underlying most Internet services, including file
transfer (FTP) and e-mail communication (SMTP). TCP/IP is
available for practically all computer systems. TCP/IP thus
offers the advantage of trouble-free communication between otherwise incompatible networks and systems.
Update A more recent version of software or firmware is called an
update. Updates are often free of charge, resolve minor
programming errors, and sometimes also offer new functions.
Upload This term designates the procedure of transmitting files
from one’s own computer to another computer in the Internet.
UPnP abbreviation for Universal Plug and Play (UPnP)
UPnP is an extension of the Microsoft Plug & Play standard
that allows devices to network globally and to exchange
services—without a central server or computer.
UPnP allows devices from all kinds of manufacturers (stereo systems, routers, printers, house controls) to be controlled via an IP-based network, with or without central
control through a gateway. It is based on a number of
standardized network protocols and data formats. Expressed simplistically, devices can communicate with
each other using UPnP to exchange information.
Today the UPnP forum specifies the UPnP standard and
certifies devices that are compliant with the standard.
