In some cases however, you may want to assign Internet information to some or all of yourPCs directly (often called “statically”), rather than allowing the device to assign it. Thisoption may be desirable (but not required) if:You have obtained one or more public IP addresses that you want to alwaysassociate with specific computers (for example, if you are using a computer as apublic web server).You maintain different subnets on your LAN (subnets are described in AppendixB).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 theaddress assigned to the LAN port on the device. By default, the LAN port isassigned the IP address 192.168.1.1. (You can change this number or anothernumber can be assigned by your ISP.)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 relatingonly to checking for and/or installing the IP protocol. Once it is installed, continue to followthe instructions for displaying each of the Internet Protocol (TCP/IP) properties. Instead ofenabling dynamic assignment of the IP addresses for the computer, DNS server and defaultgateway, click the radio buttons that enable you to enter the information manually.NoteYour PCs must have IP addresses that place them in the same subnet as the device’s LAN port.

This configures the PCs to access each other and the Internet via the device.•Configure the SSID and channel to match the SSID and channel previously configured on the device.Your wireless network can now communicate with the Internet via the device.
X7968r / X7967r / X7927r / X7922r User’s Guide73Configuring USB PCConnecting a computer to the USB port If you use the device’s USB port to connect to a PC, you must install the provided USB driversoftware on the PC. The driver enables Ethernet-over-USB communication with the device.Configuring the USB computer is a two-part process:In Part 1, you install the USB driver on the PC. If your computer is running Windows 2000, 98, 98 SE, XP or ME, follow theinstructions given below. In Part 2, you configure the IP properties on the USB PC.Part 1. Installing the USB DriverEnsure that the USB cable is not connected to the USB port on the PC. The installationprogram will prompt you when to connect the cable.This USB driver supports Windows 2000, 98, 98 SE, XP or ME1. Find the USB driver in the CD, double-click on setup.exe to start the DSLModem Setup Wizard.The Installing window displays as the Wizard prepares your system for the installation:Figure 83: USB Setup Wizard: Installing WindowIf a Microsoft digital signature dialog box is displayed, click Yes to continue.The installation program will begin copying the necessary installation files to the requiredlocations.

You do not need to restart your computer.Proceed to Part 2. Configuring IP properties on the USB PC.Part 2. Configuring IP properties on the USB PCNow that the USB driver installation is complete, you must configure the USB PC so that itsIP properties place it in the same subnet as the device’s USB port. There are two ways to dothis:The device is configured to assign an appropriate IP address to the USB PC. If you want touse this automatic assignment feature, called “DHCP server,”you must configure the USBPC to accept dynamically assigned IP information. Follow the instruction on ConfiguringEthernet PC section that corresponds to the operating system installed on your PC.If you want to assign a static IP address to the PC, follow the instructions on ConfiguringEthernet PC section and use the following information:In the Network and Dial-up Connections window, be sure to select the icon that correspondsto your new USB connection (not the one that corresponds to your Ethernet NIC). When youdisplay properties for the icon, the following text should display in the Connect Using textbox:USB IAD LAN Modem #nThe USB port on the device is preconfigured with these properties:USB port IP address:192.168.1.100 (for example)USB port subnet mask: 255.255.255.0Therefore, your PC must be configured as follows:IP address: 192.168.1.n where n is a number from 2 to 254 that does not conflict with the DHCP address range.Subnet mask: 255.255.255.0
X7968r / X7967r / X7927r / X7922r User’s Guide75IP AddressesNoteThis section refers only to IP addresses for IPv4 (version 4 of the Internet Protocol). IPv6 addresses are not covered.This section assumes basic knowledge of binary numbers, bits, and bytes.IP addresses, the Internet's version of telephone numbers, are used to identify individualnodes (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 dotteddecimal notation. The IP address 20.56.0.211 is read "twenty dot fifty-six dot zero dottwo-eleven."Structure of an IP addressIP 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 oftelephone lines, and ends with four digits that identify one specific line in that group. Similarly, IP addresses contain two kinds of information:Network IDIdentifies a particular network within the Internet or intranetHost IDIdentifies a particular computer or device on the networkThe first part of every IP address contains the network ID, and the rest of the addresscontains the host ID. The length of the network ID depends on the network's class (seefollowing section). The table below shows the structure of an IP address.Field1 Field2 Field3 Field4Class A Network ID Host IDClass B Network ID Host IDClass C Network ID Host IDHere 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 classesThe three commonly used network classes are A, B, and C. (There is also a class D but it has a special use beyond the scope of this discussion.) These classes have different uses andcharacteristics.Class A networks are the Internet's largest networks, each with room for over 16 millionhosts. 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 theinfrastructure 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. Therecan be up to 16,384 class B networks in existence. A class B network might be appropriatefor a large organization such as a business or government agency.
X7968r / X7967r / X7927r / X7922r User’s Guide76Class 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 theInternet are usually class C networks.Some important notes regarding IP addresses:The class can be determined easily from field1:field1 = 1-126: Class Afield1 = 128-191: Class Bfield1 = 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, asthose values are reserved for special uses.Subnet masksDefinitionmaskA 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 IDportion 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:255.255.255.128It's easier to see what's happening if we write this in binary: 11111111. 11111111. 11111111.10000000As 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 theremaining 7 bits in field4 for its host IDs, which range from 1 to 126 hosts (instead of theusual 0 to 255 for a class C address).Similarly, to split a class C network into four subnets, the mask is:255.255.255.192 or 11111111. 11111111. 11111111.11000000The 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.NoteSometimes 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:Class A: 255.0.0.0Class B: 255.255.0.0Class C:255.255.255.0These are called default because they are used when a network is initially configured, at which time it has no subnets.

X7968r / X7967r / X7927r / X7922r User’s Guide79Diagnosing Problem using IP UtilitiesPingPing is a command you can use to check whether your PC can recognize other computerson your network and the Internet. A ping command sends a message to the computer youspecify. If the computer receives the message, it sends messages in reply. To use it, youmust 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. Clickthe Start button, and then click Run. In the Open text box, type a statement such as thefollowing:ping 192.168.1.1Click OK. You can substitute any private IP address on your LAN or a public IP address foran Internet site, if known. If the target computer receives the message, a Command Prompt window is displayed: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 device is working (using thepreconfigured default LAN IP address 192.168.1.1) 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 aparticular Internet location, you can use the nslookup command, as explained in thefollowing section.From most other IP-enabled operating systems, you can execute the same command at acommand prompt or through a system administration utility.nslookupYou 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 name is not an entry in your ISP’sDNS table, the request is then referred to another higher-level server, and so on, until theentry is found. The server then returns the associated IP address.On Windows-based computers, you can execute the nslookup command from the Startmenu. Click the Start button, and then click Run. In the Open text box, type the following:NslookupClick 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 aswww.microsoft.com.The window will display the associate IP address, if known, as shown below:

This is provided by the ADSL/Annex A /G.Span Auto Detect feature. The standard used depends on the capability of the CO.Using Auto Detect, startup at the CPE is first attempted in Annex A. The CO is the master andthe CPE is the slave. If the result of handshake with the CO is G.Span (HS), then the CPE will switch to G.Span. If the CO does not support G.Span, then the resultant connection will be ADSL Annex A.This parameter must be set to AHS to configure the modem for A & HS ‘two-speed’ Auto Detect. For Auto Detect, all other parameters should be set to the Annex A profile.

Seedata rate, Ethernet.ADSL Asymmetric Digital Subscriber LineThe 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 itsfrequency 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 ModeA 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.

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 Dynamic Host Configuration Protocol relayA DHCP relay is a computer that forwards DHCPdata between computers that request IPaddresses and the DHCP server that assigns the addresses. Each of the device's interfaces can be configured as a DHCP relay. See DHCP.DHCP server Dynamic Host Configuration Protocol serverA 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). Thedata 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

X7968r / X7967r / X7927r / X7922r User’s Guide89Intranet A private, company-internal network that looks like part of the Internet (users access information usingweb browsers), but is accessible only by employees.IP See TCP/IP.IP address Internet Protocol addressThe 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 IPaddress 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 ProviderA company that provides Internet access to itscustomers, 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 DiodeAn electronic light-emitting device. The indicator lights on the front of the device are LEDs.MAC address Media Access Control addressThe permanent hardware address of a device, assigned by its manufacturer. MAC addresses are expressed as six pairs of hex characters, with each pair separated by colons. For example;NN:NN:NN:NN:NN:NN.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 TranslationA service performed by many routers that translates your network’s publicly known IPaddress 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.Network A group of computers that are connected together,allowing them to communicate with each other andshare resources, such as software, files, etc. A network can be small, such as a LAN, or very large, such as the Internet.
X7968r / X7967r / X7927r / X7922r User’s Guide90Network keys (Also known as encryption keys.) 64-bit and 128-bit encryption keys used in WEP wireless security schemes. The keys encrypt data over the WLAN, and only wireless PCs configured with WEP keys that correspond to the keys configured on the device can send/receive encrypted data.Network mask A network mask is a sequence of bits applied to anIP 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 CardAn 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 unitscalled 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) GroperA 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 ProtocolA 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 device uses two forms of PPP called PPPoA and PPPoE. See PPPoA, PPPoE.PPPoA Point-to-Point Protocol over ATMOne 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 PPPoAinterface per VC.PPPoE Point-to-Point Protocol over EthernetOne 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.
X7968r / X7967r / X7927r / X7922r User’s Guide91RIP Routing Information ProtocolThe original TCP/IP routing protocol. There are two versions of RIP: version I and version II. RJ-11 Registered Jack Standard-11The standard plug used to connect telephones, faxmachines, modems, etc. to a telephone port. It is a 6-pin connector usually containing four wires.RJ-45 Registered Jack Standard-45The 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 thenetwork 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 ProtocolThe 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 packetsfrom 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 ProtocolA 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
X7968r / X7967r / X7927r / X7922r User’s Guide92sequencing rules and supports re-keyingmechanisms.Triggers Triggers are used to deal with application protocols that create separate sessions. Some applications, such as NetMeeting, open secondary connections during normal operations, forexample, a connection to a server is establishedusing 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 addressof 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 packetsonly, UDP packets only, or both.Twisted pair The ordinary copper telephone wiring used by telephone companies. It contains one or more wire pairs twisted 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.UnnumberedinterfacesAn 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 IPaddress of another interface. For example, the WAN unnumbered interface of your device uses the same IP address of the LAN interface (192.168.1.1).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 CircuitA connection from your DSL router to your ISP.VCI Virtual Circuit IdentifierTogether 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 IdentifierTogether with the Virtual Circuit Identifier (VCI), theVPI uniquely identifies a VC. Your ISP will tell you the VPI for each VC they provide. See VC.

With respect to the device, WAN refers to the Internet.Web browser A software program that uses Hyper-Text TransferProtocol (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 browsersuse 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.Web site A computer on the Internet that distributes information to (and gets information from) remote users through web browsers. A web site typically consists of web pages that contain text, graphics, and hyperlinks. See hyperlink, web page.WEP Wired Equivalent Privacy (WEP) encrypts dataover WLANs. Data is encrypted into blocks of either 64 bits length or 128 bits length. Theencrypted data can only be sent and received by users with access to a private network key. Each PC on your wireless network must be manually configured with the same key as your device in order to allow wireless encrypted datatransmissions. Eavesdroppers cannot access your network if they do not know your private key. WEPis considered to be a low security option.Wireless Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or the entire communication path.See wireless LAN.Wireless LAN A wireless LAN (WLAN) is one in which a mobile user can connect to a local area network (LAN) through a wireless (radio) connection. A standard,IEEE 802.11, specifies the technologies for wireless LANs.WPA Wi-Fi Protected AccessWPA is an initiative by the IEEE and Wi-Fi Allianceto address the security limitations of WEP. WPAprovides a stronger data encryption method (called Temporal Key Integrity Protocol (TKIP)). It runs in a special, easy-to-set-up home mode called Pre-Shared Key (PSK) that allows you to manually enter a pass phrase on all the devices in your wireless network. WPA data encryption is based on a WPA master key. The master key is derived from the pass phrase and the network name (SSID) of the device.
X7968r / X7967r / X7927r / X7922r User’s Guide94It provides improved data encryption and stronger user authentication. The mode of WPA supported on your device is called Pre-Shared Key (PSK), which allows you to manually enter a type of keycalled a pass phrase.WWW World Wide WebAlso called (the) Web.
