11n Repeater User’s Manual
Field
IP Address
Description
The IP address of your router on the local area network. Your local
area network settings are based on the address assigned here.
Subnet Mask
The subnet mask of your router on the local area network.
DHCP Mode
Once your router is properly configured and DHCP Server is
enabled, the DHCP Server will manage the IP addresses and other
network configuration information for computers and other devices
connected to your Local Area Network. There is no need for you to
do this yourself.
The computers (and other devices) connected to your LAN also
need to have their TCP/IP configuration set to "DHCP" or "Obtain an
IP address automatically".
IP Pool Range
These two IP values (from and to) define a range of IP addresses
that the DHCP Server uses when assigning addresses to computers
and devices on your Local Area Network. Any addresses that are
outside of this range are not managed by the DHCP Server; these
could, therefore, be used for manually configured devices or
devices that cannot use DHCP to obtain network address details
automatically.
Your router, by default, has a static IP address of 192.168.0.1. This

Max Lease Time
The amount of time that a computer may have an IP address before
it is required to renew the lease. The lease functions just as a lease
on an apartment would. The initial lease designates the amount of
time before the lease expires. If the tenant wishes to retain the
address when the lease is expired then a new lease is established. If
the lease expires and the address is no longer needed then another
tenant may use the address.

Wireless Access Control Mode
For security reason, using MAC ACL's (MAC Address Access
List) creates another level of difficulty to hacking a network. A
MAC ACL is created and distributed to AP so that only
authorized NIC's can connect to the network. While MAC
address spoofing is a proven means to hacking a network this
can be used in conjunction with additional security measures to
increase the level of complexity of the network security
decreasing the chance of a breach.
MAC addresses can be add/delete/edit from the ACL list
depending on the MAC Access Policy.
If you choose 'Allowed Listed', only those clients whose wireless
MAC addresses are in the access control list will be able to
connect to your Access Point. When 'Deny Listed' is selected,
these wireless clients on the list will not be able to connect the

Assigning static Internet information to your PCs
If you are a typical user, you will not need to assign static
Internet information to your LAN PCs because your ISP
automatically assigns this information for you.
In some cases however, you may want to assign Internet
information to some or all of your PCs directly (often called
“statically”), rather than allowing the Wireless Gateway to assign
it. This option may be desirable (but not required) if:
•
You have obtained one or more public IP addresses that
you want to always associate with specific computers (for
example, if you are using a computer as a public web
server).
•
You maintain different subnets on your LAN (subnets are
described in Appendix B).
Before you begin, you must have the following information
available:
•
The IP address and subnet mask of each PC
•
The IP address of the default gateway for your LAN. In
most cases, this is the address assigned to the LAN port on
the Wireless Gateway. By default, the LAN port is assigned
the IP address 10.0.0.2. (You can change this number or
another number can be assigned by your ISP. See
Addressing for more information.)
•
The IP address of your ISP’s Domain Name System (DNS)
server.
On each PC to which you want to assign static information,
follow the instructions relating only to checking for and/or
installing the IP protocol. Once it is installed, continue to follow
the instructions for displaying each of the Internet Protocol
(TCP/IP) properties. Instead of enabling dynamic assignment of
the IP addresses for the computer, DNS server and default
gateway, click the radio buttons that enable you to enter the
information manually.
Note
Your PCs must have IP addresses that place them in the same
subnet as the Wireless Gateway’s LAN port. If you manually assign
IP information to all your LAN PCs, you can follow the instructions in
Addressing to change the LAN port IP address accordingly.
78
11n Repeater User’s Manual
IP Addresses, Network Masks, and
Subnets
IP Addresses
This section refers only to IP addresses for IPv4 (version 4 of the
Internet Protocol). IPv6 addresses are not covered.
Note
This section assumes basic knowledge of binary numbers, bits,
and bytes.
IP addresses, the Internet's version of telephone numbers, are
used to identify individual nodes (computers or devices) on the
Internet. Every IP address contains four numbers, each from 0
to 255 and separated by dots (periods), e.g. 20.56.0.211. These
numbers are called, from left to right, field1, field2, field3, and
field4.
This style of writing IP addresses as decimal numbers
separated by dots is called dotted decimal notation. The IP
address 20.56.0.211 is read "twenty dot fifty-six dot zero dot
two-eleven."
Structure of an IP address
IP addresses have a hierarchical design similar to that of
telephone numbers. For example, a 7-digit telephone number
starts with a 3-digit prefix that identifies a group of thousands of
telephone lines, and ends with four digits that identify one
specific line in that group.
Similarly, IP addresses contain two kinds of information:
•
Network ID
Identifies a particular network within the Internet or intranet
•
Host ID
Identifies a particular computer or device on the network
The first part of every IP address contains the network ID, and
the rest of the address contains the host ID. The length of the
network ID depends on the network's class (see following
section). The table below shows the structure of an IP address.
Field1
Class A
Class B
Field2
Network ID
Field4
Host ID
Network ID
Class C
Field3
Host ID
Network ID
Host ID
Here are some examples of valid IP addresses:
Class A: 10.30.6.125 (network = 10, host = 30.6.125)
Class B: 129.88.16.49 (network = 129.88, host = 16.49)
Class C: 192.60.201.11 (network = 192.60.201, host = 11)
Network classes
The three commonly used network classes are A, B, and C.
(There is also a class D but it has a special use beyond the
79
11n Repeater User’s Manual
scope of this discussion.) These classes have different uses
and characteristics.
Class A networks are the Internet's largest networks, each with
room for over 16 million hosts. Up to 126 of these huge
networks can exist, for a total of over 2 billion hosts. Because of
their huge size, these networks are used for WANs and by
organizations at the infrastructure level of the Internet, such as
your ISP.
Class B networks are smaller but still quite large, each able to
hold over 65,000 hosts. There can be up to 16,384 class B
networks in existence. A class B network might be appropriate
for a large organization such as a business or government
agency.
Class C networks are the smallest, only able to hold 254 hosts
at most, but the total possible number of class C networks
exceeds 2 million (2,097,152 to be exact). LANs connected to
the Internet are usually class C networks.
Some important notes regarding IP addresses:
•
The class can be determined easily from field1:
field1 = 1-126:
Class A
field1 = 128-191:
Class B
field1 = 192-223:
Class C
(field1 values not shown are reserved for special uses)
•
A host ID can have any value except all fields set to 0 or all
fields set to 255, as those values are reserved for special
uses.
Subnet masks
Definition
mask
A mask looks like a regular IP address, but contains a pattern of
bits that tells what parts of an IP address are the network ID and
what parts are the host ID: bits set to 1 mean "this bit is part of the
network ID" and bits set to 0 mean "this bit is part of the host ID."
Subnet masks are used to define subnets (what you get after
dividing a network into smaller pieces). A subnet's network ID is
created by "borrowing" one or more bits from the host ID portion
of the address. The subnet mask identifies these host ID bits.
For example, consider a class C network 192.168.1. To split this
into two subnets, you would use the subnet mask:
255.255.255.128
It's easier to see what's happening if we write this in binary:
11111111. 11111111. 11111111.10000000
As with any class C address, all of the bits in field1 through
field3 are part of the network ID, but note how the mask
specifies that the first bit in field4 is also included. Since this
extra bit has only two values (0 and 1), this means there are two
subnets. Each subnet uses the remaining 7 bits in field4 for its
host IDs, which range from 1 to 126 hosts (instead of the usual
0 to 255 for a class C address).
Similarly, to split a class C network into four subnets, the mask
is:
80

The two extra bits in field4 can have four values (00, 01, 10, 11),
so there are four subnets. Each subnet uses the remaining six
bits in field4 for its host IDs, ranging from 1 to 62.
Sometimes a subnet mask does not specify any additional
network ID bits, and thus no subnets. Such a mask is called a
default subnet mask. These masks are:
Note
Class A:
Class B:
Class C:
255.0.0.0
255.255.0.0
255.255.255.0
These are called default because they are used when a network is
initially configured, at which time it has no subnets.

UPnP Control Point Software on
Windows ME/XP
This appendix provides instructions for configuring the UPnP on
your computers to work with the Wireless Gateway.
UPnP is an architecture for pervasive peer-to-peer network
connectivity of intelligent appliances, Wireless devices, and PCs
of all form factors. It is designed to bring easy-to-use, flexible,
standards-based connectivity to ad-hoc or unmanaged
networks whether in the home, in a small business, public
spaces, or attached to the Internet. UPnP is a distributed, open
networking architecture that leverages TCP/IP and the Web
technologies to enable seamless proximity networking in
addition to control and data transfer among networked devices
in the home, office, and public spaces.
UPnP is more than just a simple extension of the plug and play
peripheral model. It is designed to support zero-configuration,
"invisible" networking, and automatic discovery for a breadth of
device categories from a wide range of vendors. This means a
device can dynamically join a network, obtain an IP address,
convey its capabilities, and learn about the presence and
capabilities of other devices. DHCP and DNS servers are
optional and are used only if available on the network. Finally, a
device can leave a network smoothly and automatically without
leaving any unwanted state behind.
UPnP Control Point Software on Windows ME
To install the control point software on Windows ME:
1. In the Control Panel, select "Add/Remove Programs".
2. In the "Add/Remove Programs Properties" dialog box, select
the "Windows Setup" tab. In the "Components" list, double click
on the "Communications" entry.
3. In the "Communications" dialog box, scroll down the
"Components" list to display the UPnP entry. Select the entry,
click "OK".
4. Click "OK" to finish the "Add/Remove Programs" dialog.
5. Reboot your system.
Once you have installed the UPnP software and you have
rebooted (and your network includes the IGD system), you
should be able to see the IGD controlled device on your network.

UPnP Control Point Software on Windows XP with
Firewall
On Windows XP versions earlier than SP2, Firewall support is
provided by the Windows XP Internet Connection Firewall. You
cannot use the Windows XP Internet Connection Firewall
support on a system that you intend to use as a UPnP control
point. If this feature is enabled, although the control point
system may display controlled devices in the list of network
devices, the control point system cannot participate in UPnP
communication. (This restriction also applies to controlled
devices running on Windows XP systems earlier than SP2.)
On Windows XP SP2 and later, Firewall support is provided by
Windows Firewall. Unlike earlier versions, Windows XP SP2
can be used on a system that you intend to use as a UPnP
control point.

Diagnosing Problem using IP Utilities
ping
Ping is a command you can use to check whether your PC can
recognize other computers on your network and the Internet. A
ping command sends a message to the computer you specify. If
the computer receives the message, it sends messages in reply.
To use it, you must know the IP address of the computer with
which you are trying to communicate.
On Windows-based computers, you can execute a ping
command from the Start menu. Click the Start button, and then
click Run. In the Open text box, type a statement such as the
following:
ping 10.0.0.2
Click OK. You can substitute any private IP address on your
LAN or a public IP address for an Internet site, if known.
If the target computer receives the message, a Command
Prompt window is displayed:
Figure 8:
Using the ping Utility
If the target computer cannot be located, you will receive the
message Request timed out.
Using the ping command, you can test whether the path to the
Wireless Gateway is working (using the preconfigured default
LAN IP address 10.0.0.2) or another address you assigned.
You can also test whether access to the Internet is working by
typing an external address, such as that for www.yahoo.com
(216.115.108.243). If you do not know the IP address of a
particular Internet location, you can use the nslookup command,
as explained in the following section.
From most other IP-enabled operating systems, you can
execute the same command at a command prompt or through a
system administration utility.
nslookup
You can use the nslookup command to determine the IP
address associated with an Internet site name. You specify the
common name, and the nslookup command looks up the name
in on your DNS server (usually located with your ISP). If that
88
11n Repeater User’s Manual
name is not an entry in your ISP’s DNS table, the request is
then referred to another higher-level server, and so on, until the
entry is found. The server then returns the associated IP
address.
On Windows-based computers, you can execute the nslookup
command from the Start menu. Click the Start button, and then
click Run. In the Open text box, type the following:
Nslookup
Click OK. A Command Prompt window displays with a bracket
prompt (>). At the prompt, type the name of the Internet address
that you are interested in, such as www.microsoft.com.
The window will display the associate IP address, if known, as
shown below:
Figure 9:
Using the nslookup Utility
There may be several addresses associated with an Internet
name. This is common for web sites that receive heavy traffic;
they use multiple, redundant servers to carry the same
information.
To exit from the nslookup utility, type exit and press [Enter] at
the command prompt.

10BASE-T
A designation for the type of wiring used by Ethernet
networks with a data rate of 10 Mbps. Also known as
Category 3 (CAT 3) wiring. See data rate, Ethernet.
100BASE-T
A designation for the type of wiring used by Ethernet
networks with a data rate of 100 Mbps. Also known as
Category 5 (CAT 5) wiring. See data rate, Ethernet.
ADSL
Asymmetric Digital Subscriber Line
The most commonly deployed "flavor" of DSL for home users
is asymmetrical DSL. The term asymmetrical refers to its
unequal data rates for downloading and uploading (the
download rate is higher than the upload rate). The
asymmetrical rates benefit home users because they
typically download much more data from the Internet than
they upload.
analog
An analog signal is a signal that has had its frequency
modified in some way, such as by amplifying its strength or
varying its frequency, in order to add information to the signal.
The voice component in DSL is an analog signal. See digital.
ATM
Asynchronous Transfer Mode
A standard for high-speed transmission of data, text, voice,
and video, widely used within the Internet. ATM data rates
range from 45 Mbps to 2.5 Gbps. See data rate.
authenticate
To verify a user’s identity, such as by prompting for a
password.
binary
The "base two" system of numbers, that uses only two digits,
0 and 1, to represent all numbers. In binary, the number 1 is
written as 1, 2 as 10, 3 as 11, 4 as 100, etc. Although
expressed as decimal numbers for convenience, IP
addresses in actual use are binary numbers; e.g., the IP
address 209.191.4.240 is
11010001.10111111.00000100.11110000 in binary. See bit,

bridging
Passing data from your network to your ISP and vice versa
using the hardware addresses of the devices at each location.
Bridging contrasts with routing, which can add more
intelligence to data transfers by using network addresses
instead. The Wireless Gateway can perform both routing and
bridging. Typically, when both functions are enabled, the
device routes IP data and bridges all other types of data. See
routing.
broadband
A telecommunications technology that can send different
types of data over the same medium. DSL is a broadband
technology.
broadcast
To send data to all computers on a network.
DHCP
Dynamic Host Configuration Protocol
DHCP automates address assignment and management.
90
11n Repeater User’s Manual
When a computer connects to the LAN, DHCP assigns it an
IP address from a shared pool of IP addresses; after a
specified time limit, DHCP returns the address to the pool.

digital
Of data, having a form based on discrete values expressed
as binary numbers (0's and 1's). The data component in DSL
is a digital signal. See analog.
DNS
Domain Name System
The DNS maps domain names into IP addresses. DNS
information is distributed hierarchically throughout the
Internet among computers called DNS servers. For example,
www.yahoo.com is the domain name associated with IP
address 216.115.108.243. When you start to access a web
site, a DNS server looks up the requested domain name to
find its corresponding IP address. If the DNS server cannot
find the IP address, it communicates with higher-level DNS
servers to determine the IP address. See domain name.
domain name
A domain name is a user-friendly name used in place of its
associated IP address. Domain names must be unique; their
assignment is controlled by the Internet Corporation for
Assigned Names and Numbers (ICANN). Domain names are
a key element of URLs, which identify a specific file at a web
site. See DNS.

IP address
Internet Protocol address
The address of a host (computer) on the Internet, consisting
of four numbers, each from 0 to 255, separated by periods,
e.g., 209.191.4.240. An IP address consists of a network ID
that identifies the particular network the host belongs to, and
a host ID uniquely identifying the host itself on that network.

92
11n Repeater User’s Manual
network
A group of computers that are connected together, allowing
them to communicate with each other and share resources,
such as software, files, etc. A network can be small, such as
a LAN, or very large, such as the Internet.
network mask
A network mask is a sequence of bits applied to an IP
address to select the network ID while ignoring the host ID.
Bits set to 1 mean "select this bit" while bits set to 0 mean
"ignore this bit." For example, if the network mask
255.255.255.0 is applied to the IP address 100.10.50.1, the
network ID is 100.10.50, and the host ID is 1. See binary, IP
address, subnet.
NIC
Network Interface Card
An adapter card that plugs into your computer and provides
the physical interface to your network cabling. For Ethernet
NICs this is typically an RJ-45 connector. See Ethernet, RJ45.
packet
Data transmitted on a network consists of units called
packets. Each packet contains a payload (the data), plus
overhead information such as where it came from (source
address) and where it should go (destination address).
ping
Packet Internet (or Inter-Network) Groper
A program used to verify whether the host associated with an
IP address is online. It can also be used to reveal the IP
address for a given domain name.
port

router, through which data flows into and out of the device.
PPP
Point-to-Point Protocol
A protocol for serial data transmission that is used to carry IP
(and other protocol) data between your ISP and your
computer. The WAN interface on the Wireless Gateway uses
two forms of PPP called PPPoA and PPPoE. See PPPoA,
PPPoE.
PPPoA
Point-to-Point Protocol over ATM
One of the two types of PPP interfaces you can define for a
Virtual Circuit (VC), the other type being PPPoE. You can
define only one PPPoA interface per VC.
PPPoE
Point-to-Point Protocol over Ethernet
One of the two types of PPP interfaces you can define for a
Virtual Circuit (VC), the other type being PPPoA. You can
define one or more PPPoE interfaces per VC.
protocol
A set of rules governing the transmission of data. In order for
a data transmission to work, both ends of the connection
have to follow the rules of the protocol.
remote
In a physically separate location. For example, an employee
away on travel who logs in to the company’s intranet is a
remote user.
RIP
Routing Information Protocol
The original TCP/IP routing protocol. There are two versions
of RIP: version I and version II.
RJ-11
Registered Jack Standard-11

modems, etc. to a telephone port. It is a 6-pin connector
usually containing four wires.
93
11n Repeater User’s Manual
RJ-45
Registered Jack Standard-45
The 8-pin plug used in transmitting data over phone lines.
Ethernet cabling usually uses this type of connector.
routing
Forwarding data between your network and the Internet on
the most efficient route, based on the data’s destination IP
address and current network conditions. A device that
performs routing is called a router.
SDNS
Secondary Domain Name System (server)
A DNS server that can be used if the primary DSN server is
not available. See DNS.
subnet
A subnet is a portion of a network. The subnet is
distinguished from the larger network by a subnet mask that
selects some of the computers of the network and excludes
all others. The subnet's computers remain physically
connected to the rest of the parent network, but they are
treated as though they were on a separate network. See
network mask.
subnet mask
A mask that defines a subnet. See network mask.
TCP
See TCP/IP.
TCP/IP
Transmission Control Protocol/Internet Protocol
The basic protocols used on the Internet. TCP is responsible
for dividing data up into packets for delivery and
reassembling them at the destination, while IP is responsible
for delivering the packets from source to destination. When
TCP and IP are bundled with higher-level applications such
as HTTP, FTP, Telnet, etc., TCP/IP refers to this whole suite
of protocols.
Telnet
An interactive, character-based program used to access a
remote computer. While HTTP (the web protocol) and FTP
only allow you to download files from a remote computer,
Telnet allows you to log into and use a computer from a
remote location.
TFTP
Trivial File Transfer Protocol
A protocol for file transfers, TFTP is easier to use than File
Transfer Protocol (FTP) but not as capable or secure.
TKIP
Temporal Key Integrity Protocol (TKIP) provides WPA with a
data encryption function. It ensures that a unique master key is
generated for each packet, supports message integrity and
sequencing rules and supports re-keying mechanisms.
triggers
Triggers are used to deal with application protocols that create
separate sessions. Some applications, such as NetMeeting,
open secondary connections during normal operations, for
example, a connection to a server is established using one port,
but data transfers are performed on a separate connection. A
trigger tells the device to expect these secondary sessions and
how to handle them.
Once you set a trigger, the embedded IP address of each
incoming packet is replaced by the correct host address so that
NAT can translate packets to the correct destination. You can
specify whether you want to carry out address replacement, and
if so, whether to replace addresses on TCP packets only, UDP
packets only, or both.
twisted pair
The ordinary copper telephone wiring used by telephone
companies. It contains one or more wire pairs twisted
94
11n Repeater User’s Manual
together to reduce inductance and noise. Each telephone
line uses one pair. In homes, it is most often installed with
two pairs. For Ethernet LANs, a higher grade called Category
3 (CAT 3) is used for 10BASE-T networks, and an even
higher grade called Category 5 (CAT 5) is used for
100BASE-T networks. See 10BASE-T, 100BASE-T, Ethernet.
unnumbered interfaces
An unnumbered interface is an IP interface that does not
have a local subnet associated with it. Instead, it uses a
router-id that serves as the source and destination address
of packets sent to and from the router. Unlike the IP address
of a normal interface, the router-id of an unnumbered
interface is allowed to be the same as the IP address of
another interface. For example, the WAN unnumbered
interface of your device uses the same IP address of the
LAN interface (10.0.0.2).
The unnumbered interface is temporary – PPP or DHCP will
assign a ‘real’ IP address automatically.
upstream
The direction of data transmission from the user to the
Internet.
VC
Virtual Circuit
A connection from your DSL router to your ISP.
VCI
Virtual Circuit Identifier
Together with the Virtual Path Identifier (VPI), the VCI
uniquely identifies a VC. Your ISP will tell you the VCI for
each VC they provide. See VC.
VPI
Virtual Path Identifier
Together with the Virtual Circuit Identifier (VCI), the VPI
uniquely identifies a VC. Your ISP will tell you the VPI for
each VC they provide. See VC.
WAN
Wide Area Network
Any network spread over a large geographical area, such as
a country or continent. With respect to the Wireless Gateway,
WAN refers to the Internet.
Web browser
A software program that uses Hyper-Text Transfer Protocol
(HTTP) to download information from (and upload to) web
sites, and displays the information, which may consist of text,
graphic images, audio, or video, to the user. Web browsers
use Hyper-Text Transfer Protocol (HTTP). Popular web
browsers include Netscape Navigator and Microsoft Internet
Explorer. See HTTP, web site, WWW.
Web page
A web site file typically containing text, graphics and
hyperlinks (cross-references) to the other pages on that web
site, as well as to pages on other web sites. When a user
accesses a web site, the first page that is displayed is called
the home page. See hyperlink, web site.
