User’s Guide Configuring your Computers 101 Field Description Authentication Type Open System: Open System authentication is not required to be successful while a client may decline to authenticate with any particular other client. Shared Key: Shared Key is only available if the WEP option is implemented. Shared Key authentication supports authentication of clients as either a member of those who know a shared secret key or a member of those who do not. IEEE 802.11 Shared Key authentication accomplishes this without the need to transmit the secret key in clear. Requiring the use of the WEP privacy mechanism. Auto: Auto is the default authentication algorithm. It will change its authentication type automatically to fulfill client’s requirement. Fragment Threshold When transmitting a packet over a network medium, sometimes the packet is broken into several segments, if the size of packet exceeds that allowed by the network medium. The Fragmentation Threshold defines the number of bytes used for the fragmentation boundary for directed messages. This value should remain at its default setting of 2346. It specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increases the “Fragment Threshold” value within the value range of 256 to 2346. Setting this value too low may result in poor network performance. Only minor modifications of this value are recommended. RTS Threshold This value should remain at its default setting of 2347. Should you encounter inconsistent data flow, only minor modifications are recommended. If a network packet is smaller than the preset “RTS threshold” size, the RTS/CTS mechanism will not be enabled. The ADSL modem (or AP) sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. Beacon Interval The Beacon Interval value indicates the frequency interval of the beacon. Enter a value between 20 and 1024. A beacon is a packet broadcast by the ADSL modem (or AP) to synchronize the wireless network. The default is 100. Data Rate The rate of data transmission should be set depending on the speed of your wireless network. You should select from a range of transmission speeds, or you can select Auto to have the ADSL modem (or AP) automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the AP and a wireless client. The default setting is Auto.

User’s Guide Configuring your Computers 103WPS Introduction of WPS Although home Wi-Fi networks have become more and more popular, users still have trouble with the initial set up of network. This obstacle forces users to use the open security and increases the risk of eavesdropping. Therefore, WPS is designed to ease set up of security-enabled Wi-Fi networks and subsequently network management (Wi-Fi Protected Setup Specification 1.0h.pdf, p. 8). The largest difference between WPS-enabled devices and legacy devices is that users do not need the knowledge about SSID, channel and security settings, but they could still surf in a security-enabled Wi-Fi network. For examples, in the initial network set up, if users want to use the PIN configuration, the only thing they need to do is entering the device PIN into registrar, starting the PIN method on that device and simply wait until the device joins the network. After the PIN method is started on both sides, a registration protocol will be initiated between the registrar and the enrollee. Typically, a registrar could be an access point or other device that is capable of managing the network. An enrollee could be an access point or a station that will join the network. After the registration protocol has been done, the enrollee will receive SSID and security settings from the registrar and then join the network. In other words; if a station attempts to join a network managed by an access point with built-in internal registrar, users will need to enter station’s PIN into the web page of that access point. If the device PIN is correct and valid and users start PIN on station, the access point and the station will automatically exchange the encrypted information of the network settings under the management of AP’s internal registrar. The station then uses this information to perform authentication algorithm, join the secure network, and transmit data with the encryption algorithm. More details will be demonstrated in the following sections. Supported WPS features Currently, Wireless Gateway supports WPS features for AP mode, AP+WDS mode, Infrastructure-Client mode, and the wireless root interface of Universal Repeater mode. Other modes such as WDS mode, Infrastructure-Adhoc mode, and the wireless virtual interface of Universal Repeater mode are not implemented with WPS features. If those unsupported modes are enforced by users, WPS will be disabled. Under the configuration of every WPS-supported mode, Wireless Gateway has Push Button method and PIN method. For each method, Wireless Gateway offers different security levels included in network credential, such as open security, WEP 64 bits, WEP 128 bits, WPA2-Personal TKIP, and WPA2-Personal AES. Users could choose either one of the methods at their convenience.
User’s Guide Configuring your Computers 104AP mode For AP mode, Wireless Gateway supports three roles, registrar, proxy, and enrollee in registration protocol. At different scenarios, Wireless Gateway will automatically switch to an appropriate role depending on the other device’s role or a specific configuration. AP as Enrollee If users know AP’s PIN and enter it into external registrar, the external registrar will configure AP with a new wireless profile such as new SSID and new security settings. The external registrar does this job either utilizing the in-band EAP (wireless) or out-of-band UPnP (Ethernet). During the WPS handshake, a wireless profile is encrypted and transmitted to AP. If the handshake is successfully done, AP will be re-initialized with the new wireless profile and wait for legacy stations or WPS stations to join its network. AP as Registrar Wireless Gateway also has a built-in internal registrar. Whenever users enter station’s PIN into AP’s webpage, click “Start PBC”, or push the physical button, AP will switch to registrar automatically. If users apply the same method on station side and the WPS handshake is successfully done, SSID and security settings will be transmitted to that station without the risk of eavesdropping. And then the station will associate with AP in a security-enabled network. AP as Proxy At this state, AP is transparent to users. If users want to configure a station or any device that is capable of being an enrollee, they have to enter device’s PIN into an external registrar and choose an appropriate wireless profile. After the PIN is entered, the external registrar will inform AP this event. AP then conveys the encrypted wireless profile between the device and the external registrar. Finally, the device will use the wireless profile and associate with AP. However, the device may connect to other APs if the wireless profile does not belong to the proxy AP. Users must carefully choose the wireless profile or create a wireless profile on an external registrar. Infrastructure-Client mode In Infrastructure-Client mode, Wireless Gateway only supports enrollee’s role. If users click “Start PIN”, click “Start PBC”, or press the physical button on Wireless Gateway, it will start to seek WPS AP. Once users apply the same method on registrar side, Wireless Gateway will receive the wireless profile upon successfully doing the registration protocol. Then Wireless Gateway will associate with an AP.
User’s Guide Configuring your Computers 105Instructions of AP’s and Client’s operations At this state, AP is transparent to users. If users want to configure a station or any device that is capable of being an enrollee, they have to enter device’s PIN into an external registrar and choose an appropriate wireless profile. After the PIN is entered, the external registrar will inform AP this event. AP then conveys the encrypted wireless profile between the device and the external registrar. Finally, the device will use the wireless profile and associate with AP. However, the device may connect to other APs if the wireless profile does not belong to the proxy AP. Users must carefully choose the wireless profile or create a wireless profile on an external registrar. This device supports Push Button method and PIN method for WPS.

User’s Guide Configuring your Computers 12615 Routing The Routing page enables you to define specific route for your Internet and network data. Most users do not need to define routes. On a typical small home or office LAN, the existing routes that set up the default gateways for your LAN hosts and for the DSL device provide the most appropriate path for all your Internet traffic. −On your LAN hosts, a default gateway directs all Internet traffic to the LAN port(s) on the DSL device. Your LAN hosts know their default gateway either because you assigned it to them when you modified your TCP/IP properties, or because you configured them to receive the information dynamically from a server whenever they access the Internet. −On the DSL device itself, a default gateway is defined to direct all outbound Internet traffic to a route at your ISP. The default gateway is assigned either automatically by your ISP whenever the device negotiates an Internet access, or manually by user to setup through the configuration. You may need to define routes if your home setup includes two or more networks or subnets, if you connect to two or more ISP services, or if you connect to a remote corporate LAN. Static Route 1. From the head Advance menu, click on Route. The following page is displayed:

It can also be specified as all zeros to indicate that this route should be used for all destinations for which no other route is defined (this is the route that creates the default gateway). Subnet Mask The network mask of the destination subnet. The default gateway uses a mask of 0.0.0.0. Next Hop The IP address of the next hop through which traffic will flow towards the destination subnet. Metric Defines the number of hops between network nodes that data packets travel. The default value is 0, which means that the subnet is directly one hop away on the local LAN network. Interface The WAN interface to which a static routing subnet is to be applied.

User’s Guide Configuring your Computers 129RIP RIP is an Internet protocol you can set up to share routing table information with other routing devices on your LAN, at your ISP’s location, or on remote networks connected to your network via the ADSL line. Most small home or office networks do not need to use RIP; they have only one Router,such as the ADSL Router, and one path to an ISP. In these cases, there is no need to share routes, because all Internet data from the network is sent to the same ISP gateway. You may want to configure RIP if any of the following circumstances apply to your network: −Your home network setup includes an additional Router or RIP-enabled PC (other than the ADSL Router). The ADSL Router and the Router will need to communicate via RIP to share their routing tables. −Your network connects via the ADSL line to a remote network, such as a corporate network. In order for your LAN to learn the routes used within your corporate network, they should both be configured with RIP. −Your ISP requests that you run RIP for communication with devices on their network. 2.

User’s Guide Configuring your Computers 16032 UPnP 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. The DSL device supports a control point for Universal Plug and Play (UPnP) version 1.0, and supports two key features: NAT Traversal and Device Identification. This feature requires one active WAN interface. In addition, the host should support this feature. In the presence of multiple WAN interfaces, select an interface on which the incoming traffic is present. With NAT Traversal, when an UPnP command is received to open ports in NAT, the application translates the request into system commands to open the ports in NAT and the firewall. The interface to open the ports on is given to UPnP when it starts up and is part of the configuration of the application. For Device Identification, the application will send a description of the DSL device as a control point back to the host making the request.

User’s Guide Configuring your Computers 17035 Dynamic DNS Configuration Overview of Dynamic DNS If some host has a dynamic IP address that keeps changing frequently, it is difficult to keep updating the IP record that is associated with the domain name of this host in the zone files. This will result in non-accessibility of this host on the Internet. Dynamic DNS service allows to keep mapping of a dynamic IP address of such host to a static hostname. Dynamic DNS services are provided by many websites. The host needs to register with some website and get a domain name. When the IP address of the host changes, it just needs to send a message to the website that's providing dynamic DNS service to this host. For this to work, an automated update client needs to be implemented. These update clients send update messages to the servers whenever there is some change in the IP address of that host. Then, the server updates the entries for that host and replies back with some return code. Above Figure explains one such scenario in which a host gets a dynamic IP address for itself from a DHCP server. As the host has registered with one of the dynamic DNS service providers on the Internet, it sends an update message to the service provider with host name and changed IP address. The service provider updates the new IP address of the host in the zone files that have entry for that host name and replies back with some return code. The return code communicates the success or failure of the update message. This process is repeated every time the host's IP address changes. If the dynamic DNS service provider is notified of the same IP address again and again, then it considers it an abuse and might block the host name. To avoid this scenario, the IP address that was successfully updated to the ISP is stored on the unit. Whenever we receive an IP address change notification, the new IP address is compared with the IP address that was stored on the last update. If they differ, then only an
User’s Guide Configuring your Computers 171update request is sent. However, when the system comes up there is no way of knowing what was the IP address on last successful update before the system went down. You need to give the command “system config save“ periodically to save this IP address on Flash. Registering With Dynamic DNS Service Provider Currently, Wireless ADSL2+ Router supports two Dynamic DNS service providers, www.tzo.com and www.dyndns.com. To use their Dynamic DNS service, you first need to visit the Web site of a service provider and register. While registering, you need to provide your username, password, and hostname as mandatory parameters. A service provider may also prompt you to fill some optional parameters. Configuring IP Interfaces You need to create a Dynamic DNS interface per IP interface and can only create one Dynamic DNS interface service on one IP interface. For more information on creating IP interfaces, refer to section Creating IP interfaces. Note www.dyndns.org provides three kinds of services - Dynamic DNS, Custom DNS and Static DNS. You can create different domains in these systems. Custom DNS service is a full DNS solution for newly purchased domains or domains you already own. A web-based interface provides complete control over resource records and your entire domain, including support for dynamic IPs and automated updates. Static DNS service points a DNS hostname in some domain owned by dyndns.org to the user's ISP-assigned static or pseudo-static IP address. DynDNS service points a fixed hostname in some domain owned by dyndns.org to the user's ISP-assigned dynamic IP address. This allows more frequent update of IP addresses, than allowed by Static DNS.

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 ADSL2+ Router 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 ADSL2+ Router. By default, the LAN port is assigned the IP address 192.168.1.1. (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 ADSL2+ Router’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.
User’s Guide IP Addresses, Network Masks, and Subnets 215B IP Addresses, Network Masks, and Subnets IP Addresses Note This 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 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 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 = 30.6.125) 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
User’s Guide IP Addresses, Network Masks, and Subnets 216scope 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:
User’s Guide IP Addresses, Network Masks, and Subnets 217255.255.255.192 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. Note 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: 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.

User’s Guide Troubleshooting 220Diagnosing 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 192.168.1.1 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 14: 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 ADSL2+ Router is working (using the preconfigured 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 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.
User’s Guide Troubleshooting 221nslookup 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 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 15: 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.

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 ADSL2+ Router 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.
User’s Guide Glossary 223When 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 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 ADSL2+ Router'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. download To transfer data in the downstream direction, i.e., from the Internet to the user. DSL Digital Subscriber Line A technology that allows both digital data and analog voice signals to travel over existing copper telephone lines. encryption keys See network keys Ethernet The most commonly installed computer network technology, usually using twisted pair wiring. Ethernet data rates are 10 Mbps and 100 Mbps. See also 10BASE-T, 100BASE-T, twisted pair. FTP File Transfer Protocol A program used to transfer files between computers connected to the Internet. Common uses include uploading new or updated files to a web server, and downloading files from a web server. Gbps Abbreviation of Gigabits per second, or one billion bits per second. Internet data rates are often expressed in Gbps. host A device (usually a computer) connected to a network. HTTP Hyper-Text Transfer Protocol HTTP is the main protocol used to transfer data from web
User’s Guide Glossary 224sites so that it can be displayed by web browsers. See web browser, web site. Hub A hub is a place of convergence where data arrives from one or more directions and is forwarded out in one or more directions. It connects an Ethernet bridge/Router to a group of PCs on a LAN and allows communication to pass between the networked devices. ICMP Internet Control Message Protocol An Internet protocol used to report errors and other network-related information. The ping command makes use of ICMP. IEEE The Institute of Electrical and Electronics Engineers is a technical professional society that fosters the development of standards that often become national and international standards. Internet The global collection of interconnected networks used for both private and business communications. 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 An electronic light-emitting device. The indicator lights on the front of the Wireless ADSL2+ Router are LEDs. MAC address Media Access Control address The 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 Translation 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.
User’s Guide Glossary 225network 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 Wireless ADSL2+ Router 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.
User’s Guide Glossary 226RJ-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
User’s Guide Glossary 227together 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 (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 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 ADSL2+ Router, 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. 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. WWW World Wide Web
