11n Repeater User’s Manual
Field Description
IP Address The IP address of your router on the local area network. Your local
area network settings are base d on the address as signed he re.
Subnet Mask The subnet mask of your router on the local area network.
DHCP Mode Once your router is properly configur ed and DHCP Server is
enabled, the DHCP Server will manage the IP addresses and ot her network configuration informati on for computers a nd other dev ices connected to your Local Area Net work. Th ere is n o need fo r 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 addr esses
that the DHCP Server uses when assigning addresses to computers and devices on your Local Area Net work. Any address es that a re outside of this range are not managed by the DHCP Server; these could, therefore, be used for manually configur ed devices or devices that cannot use DHCP to obtain net work address details automatically.
Your router, by default, has a static IP address of 192.168. 0.1. This means that addresses 192.168.0.2 to 192.168.0.254 can be made available for allocation by the DHCP Serv er.
Max Lease Time Th e amoun t of time that a comput er may have an IP addres s before
it is required to renew the lease. T he leas e functi ons jus t as a lease on an apartment would. The initial lease des ignates the amo unt of time before the lease expi res. If th e tenan t wishes to retain the address when the lease is expir ed then a n e w lease is establi shed. If the lease expires and the ad dress i s no long er neede d then another tenant may use the addre ss.
Domain Name Domain name for the dhcp server scope.
DNS Servers DNS Server address for the dhcp se rver scope.
IP Address The IP address to be configured for your computer or device on the
local area network.For example, 192.168.0. 2.

Wireless Access Control Mode
For security reason, using MAC ACL's (MAC Address Access List) creates another level of difficulty to ha cking a networ k. A MAC ACL is created and distributed to AP so that only authorized NIC's can connect to the network. Wh ile 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 whos e 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 Access Point. To access the Wireless Network Access Control page:

Assigning static Internet information to y our 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 t his info rmation f or y ou.
In some cases however, you m ay want t o assi gn Intern et 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 comput ers (for example, if you are using a comput er as a pu blic web server).
• You maintain different subnets on your LAN (subnets are described in Appendix B).
Before you begin, you must have t he follo wing informat ion available:
Note
• 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 assign ed to the LA N 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 informati on, follow the instructions relating only to checking for and/or installing the IP protocol. Once it is in stalle d, contin ue to foll ow the instructions for displayin g each of t he Inte rnet Proto col (TCP/IP) properties. Instead of enabling dynamic assignment of the IP addresses for the computer, DNS server and def ault gateway, click the radio buttons t hat enabl e you to ent er the information manually.
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 foll ow the inst ructions i n Addressing to change the LAN port IP address accordingly.

Subnets
IP Addresses
This section refers only to IP addresses for IPv4 (ve rsion 4 of the Internet Protocol). IPv6 addresses are not covered.
Note
This section assumes basic knowledge of bi nary numbe rs, bits, and bytes.
IP addresses, the Internet's version of telephone num bers, 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 exam ple, a 7 -digi t telepho ne numbe r 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 contai n two kind s of informat ion:
• Network ID Identifies a particular network within the Int ernet or intranet
• Host ID Identifies a particular computer or device o n 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 Field2 Field3 Field4
Class A Network ID Host ID Class B Network ID Host ID Class C Network ID Host ID
Here are some examples of valid IP addresses: Class A: 10.30.6.125 (network = 10, host = 30.6.12 5)
Class B: 129.88.16.49 (network = 129.8 8, 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 diff erent uses and characteristics.
Class A networks are the Internet's largest networks, each wit h room for over 16 million hosts. Up to 126 of these huge networks can exist, for a total of ov er 2 bi llion ho sts. Becau se 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 a ppropriat e 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 net works 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 valu e except a ll fields set to 0 or all fields set to 255, as those values are reserved for special uses.
Definition
mask
Subnet masks
A mask looks like a regular IP address, but contains a pattern of bits that tells what parts of an I P address a re the net work 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 "t his bit i s part of the host ID."
Subnet masks are used to define subnets (what you get after
dividing a network into smaller pieces). A subn et's network ID is created by "borrowing" one o r more bit s from the host ID po rtion of the address. The subnet mask id entifies t hese ho st ID bit s.
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 mean s there are t wo subnets. Each subnet uses the remaining 7 bits in field4 for its host IDs, which range from 1 to 126 h osts (i nstead of the usu al 0 to 255 for a class C address).
Similarly, to split a class C network into four subnets, the mask is:
80
11n Repeater User’s Manual
255.255.255.192 or 11111111. 11111111.
11111111.11000000
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 subnet s. Such a mask i s called a default subnet mask. These masks are:
Note
Class A: 255.0.0.0 Class B: 255.255.0.0 Class C: 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.

C 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, p ublic spaces, or attached to the Internet. UPnP is a dist ribute d, 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 simpl e extensio n of the p lug and play peripheral model. It is designed to support zero-configuration, "invisible" networking, and automatic discovery fo r a breadth of device categories from a wide range of vendors. This means a device can dynamically join a net work, o btain an IP addres s, 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 networ k. Finally, a device can leave a network smoothly and automati cally with out leaving any unwanted state behin d.
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 P rograms" dialo g.
5. Reboot your system.
Once you have installed th e UPnP software a nd you hav e rebooted (and your network includes the IGD system), you should be able to see the IGD contro lled dev ice on y our netwo rk.

Diagnosing Problem using IP Utilities
ping
Ping is a command you can use to check whether yo ur PC can recognize other computers on your n etwork and the Int ernet. 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 t est wh ether 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 worki ng 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 ca n use th e nslookup command, as explained in the following section.
From most other IP-enabled o perating syst ems, yo u can execute the same command at a command prompt or through a system administration utility.
nslookup
You can use the nslookup comma nd to determi ne the I P address associated with an Internet site name. You sp ecify the common name, and the nslookup command looks up the name in on your DNS server (usually located with your ISP). If that

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,
IP address, network mask.
bit Short for "binary digit," a bit is a number that can have two
values, 0 or 1. See binary.
bps bits per second 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 Gate way can perf orm both routing and bridging. Typically, when both functions are enabled, the device routes IP data and bridges all other types of data. See routing.

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.
DHCP relay Dynami c Ho st Configuration Protocol relay
A DHCP relay is a computer that forwards DHCP data between computers that request IP addresses and the DHCP server that assigns the addresses. Each of the Wireless Gateway's interfaces can be configured as a DHCP relay. See DHCP.
DHCP server Dynamic Host Configuration Protocol server
A DHCP server is a computer that is responsible for assigning IP addresses to the computers on a LAN. See
DHCP.
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.

intranet A private, company-internal network that looks like part of the
Internet (users access information using web browsers), but is accessible only by employees.
IP See TCP/IP. 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. A network mask is used to define the network ID and the host ID. Because IP addresses are difficult to remember, they usually have an associated domain name that can be specified instead. See domain name, network mask.
ISP Internet Service Provider
A company that provides Internet access to its customers, usually for a fee.
LAN Local Area Network
A network limited to a small geographic area, such as a home or small office.
LED Light Emitting Diode

mask See network mask. Mbps Abbreviation for Megabits per second, or one million bits per
second. Network data rates are often expressed in Mbps.
NAT Network Address Tra nslation
A service performed by many routers that translates your network’s publicly known IP address into a private IP address for each computer on your LAN. Only your router and your LAN know these addresses; the outside world sees only the public IP address when talking to a computer on your LAN.
92

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, RJ-
45.
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 A physical access point to a device such as a computer or
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 Wi reless 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
The standard plug used to connect telephones, fax machines, modems, etc. to a telephone port. It is a 6-pin connector usually containing four wires.
93

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 de al with application protocols that creat e
separate sessions. Some applications, such as NetMeeting, open secondary connections during normal operations, for example, a connection to a server is established u sing 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 t o the correct destinat ion. 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 Wire less 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, grap hics 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.
