Optimizing Wireless Connectivity and Security 4-1February 2005Chapter 4 Optimizing Wireless Connectivity and SecurityThis chapter describes how to configure the wireless features of your wireless router. In planning your wireless network, you should consider the level of security required. You should also select the physical placement of your firewall in order to maximize the network speed. The full manual with detailed how to instructions is available on line at http://kbserver.netgear.com/ and via the Documentation link in the configuration utility of the wireless router.Observe Performance, Placement, and Range GuidelinesThe operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless firewall. The latency, data throughput performance, and notebook power consumption of wireless adapters also vary depending on your configuration choices.For best results, place your firewall:• Near the center of the area in which your computers will operate.• In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls).• Away from sources of interference, such as computers, microwaves, and 2.4 GHz cordless phones.• Away from large metal surfaces.• Place the router where ventilation is not blocked. Do not stack the router on other electronic equipment or stack items on top of the router. The time it takes to establish a wireless connection can vary depending on both your security settings and placement. WEP connections can take slightly longer to establish. Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router.
NETGEAR Wireless Router Setup Manual4-2 Optimizing Wireless Connectivity and SecurityFebruary 2005Implement Appropriate Wireless Security Unlike wired network data, your wireless data transmissions can be received well beyond your walls by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The wireless router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.Figure 4-1: wireless router wireless data security optionsThere are several ways you can enhance the security of your wireless network.•Restrict Access Based on MAC Address. You can restrict access to only trusted computers so that unknown computers cannot wirelessly connect to the wireless router. MAC address filtering adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed. •Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of the SSID, only devices that have the correct SSID can connect. This nullifies the wireless network ‘discovery’ feature of some products such as Windows XP, but the data is still fully exposed to a determined snoop using specialized test equipment like wireless sniffers.•WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption will block all but the most determined eavesdropper. Note: Indoors, computers can connect over 802.11b/g wireless networks at ranges of up to 300 feet. Such distances can allow for others outside of your immediate area to access your network.:LUHOHVV'DWD6HFXULW\2SWLRQV5DQJHXSWRIRRWUDGLXV2SHQV\VWHPHDV\EXWQRVHFXULW\0$&DFFHVVOLVWQRGDWDVHFXULW\:(3VHFXULW\EXWVRPHSHUIRUPDQFHLPSDFW:3$36.YHU\VWURQJVHFXULW\.%4'%!2
NETGEAR Wireless Router Setup ManualOptimizing Wireless Connectivity and Security 4-3February 2005•WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides strong data security. WPA-PSK will block eavesdropping. Because this is a new standard, wireless device driver and software availability may be limited. •Turn Off the Wired LAN. If you disable the wireless LAN, wireless devices cannot communicate with the router at all. You might choose to turn off the wireless the LAN when you are away and the others in the household all use wired connections.Understanding Wireless SettingsTo configure the Wireless settings of your firewall, click the Wireless link in the main menu of the browser interface. •Name (SSID). The SSID is also known as the wireless network name. Enter a value of up to 32 alphanumeric characters. In a setting where there is more than one wireless network, different wireless network names provide a means for separating the traffic.

Troubleshooting Common Problems 6-1February 2005Chapter 6Troubleshooting Common ProblemsThis chapter gives information about troubleshooting your Wireless Router. After each problem description, instructions are provided to help you diagnose and solve the problem.Basic FunctioningAfter you turn on power to the router, the following sequence of events should occur:1. When power is first applied, verify that the Power light is on.2. After approximately 10 seconds, verify that:a. The power light is solid green.b. The LAN port lights are lit for any local ports that are connected.c. The Internet port light is lit.If a port’s light is lit, a link has been established to the connected device. If a LAN port is connected to a 100 Mbps device, verify that the port’s light is green. If the port is 10 Mbps, the light will be amber.If any of these conditions does not occur, refer to the appropriate following section.Power Light Not OnIf the Power and other lights are off when your router is turned on:• Make sure that the power cord is properly connected to your router and that the power supply adapter is properly connected to a functioning power outlet. • Check that you are using the power adapter supplied by NETGEAR for this product.If the error persists, you have a hardware problem and should contact technical support.
NETGEAR Wireless Router Setup Manual6-2 Troubleshooting Common ProblemsFebruary 2005Lights Never Turn Off When the router is turned on, the lights turns on for about 10 seconds and then turn off. If all the lights stay on, there is a fault within the router.If all lights are still on one minute after power up:• Cycle the power to see if the router recovers.• Clear the router’s configuration to factory defaults. This procedure is explained in “Restoring the Default Configuration and Password” on page 6-7.If the error persists, you might have a hardware problem and should contact technical support.LAN or Internet (WAN) Port Lights Not OnIf either the LAN lights or Internet light do not light when the Ethernet connection is made, check the following:• Make sure that the Ethernet cable connections are secure at the router and at the hub or workstation.• Make sure that power is turned on to the connected hub or workstation.• Be sure you are using the correct cable:— When connecting the router’s Internet port to a cable or DSL modem, use the cable that was supplied with the cable or DSL modem. This cable could be a standard straight-through Ethernet cable or an Ethernet crossover cable.Troubleshooting the Web Configuration InterfaceIf you are unable to access the router’s Web Configuration interface from a computer on your local network, check the following:• Check the Ethernet connection between the computer and the router as described in the previous section.• Make sure both your computer’s IP address and DNS server address is acquired automatically via DHCP. Refer to the tutorials on the CD for assistance with configuring your computer for DHCLP.
NETGEAR Wireless Router Setup ManualTroubleshooting Common Problems 6-3February 2005Note: If your computer’s IP address is shown as 169.254.x.x, the computer is not configured correctly for your network. Recent versions of Windows and MacOS will generate and assign a 169.254.x.x IP address if the computer cannot reach a DHCP server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection from the computer to the router and reboot your computer.• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure the Java applet is loaded.• Try quitting the browser and launching it again.• Make sure you are using the correct login information. The URL for the router is http://www.routerlogin.net or http://www.routerlogin.com. The factory default login name is admin and the password is password, both in lower case letters. Make sure that CAPS LOCK is off when entering this information.If the router does not save changes you have made in the Web Configuration Interface, check the following:• When entering configuration settings, be sure to click the APPLY button before moving to another menu or tab, or your changes are lost. • Click the Refresh or Reload button in the Web browser. The changes may have occurred, but the Web browser may be caching the old configuration.Troubleshooting the ISP ConnectionIf your router is unable to access the Internet, you should first determine whether the router is able to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address, your router must request an IP address from the ISP. You can determine whether the request was successful using the Web Configuration Manager.To check the WAN IP address: 1. Launch your browser and select an external site such as www.netgear.com2. Access the Main Menu of the router’s configuration at http://www.routerlogin.net. When prompted, enter admin for the user name and password for the password, both in lower case letters.3. Under the Maintenance heading, select Router Status4. Check that an IP address is shown for the WAN Port If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.
NETGEAR Wireless Router Setup Manual6-4 Troubleshooting Common ProblemsFebruary 2005If your router is unable to obtain an IP address from the ISP, you may need to force your cable or DSL modem to recognize your new router by performing the following procedure:1. Turn off power to the cable or DSL modem. 2. Turn off power to your router. 3. Wait five minutes and reapply power to the cable or DSL modem. 4. When the modem’s lights indicate that it has reacquired sync with the ISP, reapply power to your router.5. Then restart your computer.If your router is still unable to obtain an IP address from the ISP, the problem may be one of the following:• Your ISP may require a login program. Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.• If your ISP requires a login, you may have incorrectly set the login name and password in the router.• Your ISP may check for your computer's host name. Assign the computer Host Name of your ISP account as the Account Name in the Basic Settings menu.• Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for your computer’s MAC address. In this case:Inform your ISP that you have bought a new network device, and ask them to use the router’s MAC address.ORConfigure your router to spoof your computer’s MAC address. This can be done in the Basic Settings menu. If your router can obtain an IP address, but your computer is unable to load any Web pages from the Internet:• Your computer may not recognize any DNS server addresses. A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the router’s configuration, reboot your computer and verify the DNS address as described in “Install or Verify Windows Networking Components” on page B-9. Alternatively, you may configure your computer manually with DNS addresses, as explained in your operating system documentation.
NETGEAR Wireless Router Setup ManualTroubleshooting Common Problems 6-5February 2005• Your computer may not have the router configured as its TCP/IP gateway.If your computer obtains its information from the router by DHCP, reboot the computer and verify the gateway address as described in “Install or Verify Windows Networking Components” on page B-9.Troubleshooting a TCP/IP Network Using a Ping UtilityMost TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP network is made very easy by using the ping utility in your computer or workstation.Testing the LAN Path to Your RouterYou can ping the router from your computer to verify that the LAN path to your router is set up correctly.To ping the router from a running Windows 95 or later:1. From the Windows toolbar, click on the Start button and select Run.2. In the field provided, type Ping followed by the IP address of the router, as in this example:ping www.routerlogin.net3. Click on OK.You should see a message like this one:Pinging <IP address> with 32 bytes of dataIf the path is working, you see this message:Reply from < IP address >: bytes=32 time=NN ms TTL=xxxIf the path is not working, you see this message:Request timed outIf the path is not functioning correctly, you could have one of the following problems:• Wrong physical connections— Make sure the LAN port LED is on. If the LED is off, follow the instructions in “LAN or Internet (WAN) Port Lights Not On” on page 6-2.
NETGEAR Wireless Router Setup Manual6-6 Troubleshooting Common ProblemsFebruary 2005— Check that the corresponding Link LEDs are on for your network interface card and for the hub ports (if any) that are connected to your workstation and router.• Wrong network configuration— Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on your computer or workstation.— Verify that the IP address for your router and your workstation are correct and that the addresses are on the same subnet.Testing the Path from Your Computer to a Remote DeviceAfter verifying that the LAN path works correctly, test the path from your computer to a remote device. From the Windows run menu, type:PING -n 10 <IP address>where <IP address> is the IP address of a remote device such as your ISP’s DNS server.If the path is functioning correctly, replies as in the previous section are displayed. If you do not receive replies:— Check that your computer has the IP address of your router listed as the default gateway. If the IP configuration of your computer is assigned by DHCP, this information will not be visible in your computer’s Network Control Panel. Verify that the IP address of the router is listed as the default gateway as described in “Install or Verify Windows Networking Components” on page B-9.— Check to see that the network address of your computer (the portion of the IP address specified by the netmask) is different from the network address of the remote device.— Check that your cable or DSL modem is connected and functioning.— If your ISP assigned a host name to your computer, enter that host name as the Account Name in the Basic Settings menu.— Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers. Many broadband ISPs restrict access by only allowing traffic from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single computer connected to that modem. If this is the case, you must log in to the router and use the Basic Settings menu to configure your router to “clone” or “spoof” the MAC address from the authorized computer.
NETGEAR Wireless Router Setup ManualTroubleshooting Common Problems 6-7February 2005Restoring the Default Configuration and PasswordThis section explains how to restore the factory default configuration settings, changing the router’s administration password to password. You can erase the current configuration and restore factory defaults in two ways:• Use the Erase function of the router (see “Erasing the Configuration” on page 5-3).• Use the Default Reset button on the rear panel of the router. Use this method for cases when the administration password or IP address is not known.To restore the factory default configuration settings without knowing the administration password or IP address, you must use the Default Reset button on the rear panel of the router.1. Press and hold the Default Reset button until the power light blinks on (about 10 seconds).2. Release the Default Reset button and wait for the router to reboot.If the wireless router fails to restart or the power light continues to blink or turns solid amber, the unit may be defective. If the error persists, you might have a hardware problem and should contact technical support.Note: Erasing the configuration will restore the factory default settings. When the router is in the factory default state, the Smart Wizard installation assistant will automatically connect to your browser. You can either go through the installation wizard again, or you can bypass the wizard by following the instructions at “How to Bypass the Configuration Assistant” on page 3-11.

If you haven’t been given host or domain names, you can use the following examples as a guide:• If your main e-mail account with your ISP is aaa@yyy.com, then use aaa as your host name. Your ISP might call this your account, user, host, computer, or system name. • If your ISP’s mail server is mail.xxx.yyy.com, then use xxx.yyy.com as the domain name.ISP Host Name: _________________________ ISP Domain Name: _______________________For Wireless Access: See the configuration worksheet at “Information to Gather Before Changing Basic Wireless Settings“ on page 4-5.Preparing Your Computers for TCP/IP NetworkingComputers access the Internet using a protocol called TCP/IP (Transmission Control Protocol/Internet Protocol). Each computer on your network must have TCP/IP installed and selected as its networking protocol. If a Network Interface Card (NIC) is already installed in your computer, then TCP/IP is probably already installed as well.
NETGEAR Wireless Router Setup ManualB-4 Preparing Your NetworkFebruary 2005Most operating systems include the software components you need for networking with TCP/IP:•Windows® 95 or later includes the software components for establishing a TCP/IP network. • Windows 3.1 does not include a TCP/IP component. You need to purchase a third-party TCP/IP application package such as NetManage Chameleon.• Macintosh Operating System 7 or later includes the software components for establishing a TCP/IP network.• All versions of UNIX or Linux include TCP/IP components. Follow the instructions provided with your operating system or networking software to install TCP/IP on your computer.In your IP network, each computer and the firewall must be assigned a unique IP addresses. Each computer must also have certain other IP configuration information such as a subnet mask (netmask), a domain name server (DNS) address, and a default gateway address. In most cases, you should install TCP/IP so that the computer obtains its specific network configuration information automatically from a DHCP server during bootup. For a detailed explanation of the meaning and purpose of these configuration items, refer to “Appendix B, “Network, Routing, and Firewall Basics.” The wireless router is shipped preconfigured as a DHCP server. The firewall assigns the following TCP/IP configuration information automatically when the PCs are rebooted:• PC or workstation IP addresses—192.168.1.2 through 192.168.1.254• Subnet mask—255.255.255.0• Gateway address (the firewall)—192.168.1.1These addresses are part of the IETF-designated private address range for use in private networks.Configuring Windows 95, 98, and Me for TCP/IP NetworkingAs part of the PC preparation process, you need to manually install and configure TCP/IP on each networked PC.

NETGEAR Wireless Router Setup ManualB-20 Preparing Your NetworkFebruary 2005Verifying the Readiness of Your Internet AccountFor broadband access to the Internet, you need to contract with an Internet service provider (ISP) for a single-user Internet access account using a cable modem or DSL modem. This modem must be a separate physical box (not a card) and must provide an Ethernet port intended for connection to a Network Interface Card (NIC) in a computer. Your firewall does not support a USB-connected broadband modem.For a single-user Internet account, your ISP supplies TCP/IP configuration information for one computer. With a typical account, much of the configuration information is dynamically assigned when your PC is first booted up while connected to the ISP, and you will not need to know that dynamic information. In order to share the Internet connection among several computers, your firewall takes the place of the single PC, and you need to configure it with the TCP/IP information that the single PC would normally use. When the firewall’s Internet port is connected to the broadband modem, the firewall appears to be a single PC to the ISP. The firewall then allows the PCs on the local network to masquerade as the single PC to access the Internet through the broadband modem. The method used by the firewall to accomplish this is called Network Address Translation (NAT) or IP masquerading.Are Login Protocols Used?Some ISPs require a special login protocol, in which you must enter a login name and password in order to access the Internet. If you normally log in to your Internet account by running a program such as WinPOET or EnterNet, then your account uses PPP over Ethernet (PPPoE). When you configure your router, you will need to enter your login name and password in the router’s configuration menus. After your network and firewall are configured, the firewall will perform the login task when needed, and you will no longer need to run the login program from your PC. It is not necessary to uninstall the login program.What Is Your Configuration Information?More and more, ISPs are dynamically assigning configuration information. However, if your ISP does not dynamically assign configuration information but instead used fixed configurations, your ISP should have given you the following basic information for your account:
NETGEAR Wireless Router Setup ManualPreparing Your Network B-21February 2005• An IP address and subnet mask• A gateway IP address, which is the address of the ISP’s router• One or more domain name server (DNS) IP addresses• Host name and domain suffixFor example, your account’s full server names may look like this:mail.xxx.yyy.com In this example, the domain suffix is xxx.yyy.com.If any of these items are dynamically supplied by the ISP, your firewall automatically acquires them.If an ISP technician configured your PC during the installation of the broadband modem, or if you configured it using instructions provided by your ISP, you need to copy the configuration information from your PC’s Network TCP/IP Properties window or Macintosh TCP/IP Control Panel before reconfiguring your PC for use with the firewall. These procedures are described next.Obtaining ISP Configuration Information for Windows ComputersAs mentioned above, you may need to collect configuration information from your PC so that you can use this information when you configure the wireless router. Following this procedure is only necessary when your ISP does not dynamically supply the account information. To get the information you need to configure the firewall for Internet access:1. On the Windows taskbar, click the Start button, point to Settings, and then click Control Panel.2. Double-click the Network icon.The Network window opens, which displays a list of installed components.3. Select TCP/IP, and then click Properties.The TCP/IP Properties dialog box opens.4. Select the IP Address tab.If an IP address and subnet mask are shown, write down the information. If an address is present, your account uses a fixed (static) IP address. If no address is present, your account uses a dynamically-assigned IP address. Click “Obtain an IP address automatically”.5. Select the Gateway tab.
NETGEAR Wireless Router Setup ManualB-22 Preparing Your NetworkFebruary 2005If an IP address appears under Installed Gateways, write down the address. This is the ISP’s gateway address. Select the address and then click Remove to remove the gateway address.6. Select the DNS Configuration tab.If any DNS server addresses are shown, write down the addresses. If any information appears in the Host or Domain information box, write it down. Click Disable DNS.7. Click OK to save your changes and close the TCP/IP Properties dialog box.You are returned to the Network window.8. Click OK.9. Reboot your PC at the prompt. You may also be prompted to insert your Windows CD.Obtaining ISP Configuration Information for Macintosh ComputersAs mentioned above, you may need to collect configuration information from your Macintosh so that you can use this information when you configure the wireless router. Following this procedure is only necessary when your ISP does not dynamically supply the account information. To get the information you need to configure the firewall for Internet access:1. From the Apple menu, select Control Panels, then TCP/IP.The TCP/IP Control Panel opens, which displays a list of configuration settings. If the “Configure” setting is “Using DHCP Server”, your account uses a dynamically-assigned IP address. In this case, close the Control Panel and skip the rest of this section.2. If an IP address and subnet mask are shown, write down the information. 3. If an IP address appears under Router address, write down the address. This is the ISP’s gateway address.4. If any Name Server addresses are shown, write down the addresses. These are your ISP’s DNS addresses.5. If any information appears in the Search domains information box, write it down.6. Change the “Configure” setting to “Using DHCP Server”.7. Close the TCP/IP Control Panel.
NETGEAR Wireless Router Setup ManualPreparing Your Network B-23February 2005Restarting the NetworkOnce you’ve set up your computers to work with the firewall, you must reset the network for the devices to be able to communicate correctly. Restart any computer that is connected to the firewall.After configuring all of your computers for TCP/IP networking and restarting them, and connecting them to the local network of your wireless router, you are ready to access and configure the firewall.

February 2005Glossary 1GlossaryUse the list below to find definitions for technical terms used in this manual.List of Glossary Terms802.11bIEEE specification for wireless networking at 11 Mbps using direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.5GHz.802.11gA soon to be ratified IEEE specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.5GHz. 802.11g is backwards compatible with 802.11b.Cat 5Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network operating at 10 Mbits/second (10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be rated as Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA). This rating will be printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four twisted pairs, and terminated with an RJ45 type connector. In addition, there are restrictions on maximum cable length for both 10 and 100 Mbits/second networks.DHCPAn Ethernet protocol specifying how a centralized DHCP server can assign network configuration information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and gateway (router) addresses.DNSShort for Domain Name System (or Service), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.
NETGEAR Wireless Router Setup Manual2GlossaryFebruary 2005Domain NameA descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.DSLShort for digital subscriber line, but is commonly used in reference to the asymmetric version of this technology (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate). ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world gain access. Dynamic Host Configuration ProtocolDHCP. An Ethernet protocol specifying how a centralized DHCP server can assign network configuration information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and gateway (router) addresses.GatewayA local device, usually a router, that connects hosts on a local network to other networks.IPInternet Protocol is the main internetworking protocol used in the Internet. Used in conjunction with the Transfer Control Protocol (TCP) to form TCP/IP.IP AddressA four-byte number uniquely defining each host on the Internet, usually written in dotted-decimal notation with periods separating the bytes (for example, 134.177.244.57). Ranges of addresses are assigned by Internic, an organization formed for this purpose. ISPInternet service provider.Internet ProtocolThe main internetworking protocol used in the Internet. Used in conjunction with the Transfer Control Protocol (TCP) to form TCP/IP.local area networkLAN. A communications network serving users within a limited area, such as one floor of a building. A LAN typically connects multiple personal computers and shared network devices such as storage and printers. Although many technologies exist to implement a LAN, Ethernet is the most common for connecting personal computers.
NETGEAR Wireless Router Setup ManualGlossary 3February 2005MAC addressThe Media Access Control address is a unique 48-bit hardware address assigned to every network interface card. Usually written in the form 01:23:45:67:89:ab.MbpsMegabits per second.Point-to-Point ProtocolPPP. A protocol allowing a computer using TCP/IP to connect directly to the Internet.PPPoAPPPoA. PPP over ATM is a protocol for connecting remote hosts to the Internet over an always-on connection by simulating a dial-up connection.PPPoEPPPoE. PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an always-on connection by simulating a dial-up connection.PPP over ATMPPPoA. PPP over ATM is a protocol for connecting remote hosts to the Internet over an always-on connection by simulating a dial-up connection.PPTPPoint-to-Point Tunneling Protocol. A method for establishing a virtual private network (VPN) by embedding Microsoft’s network protocol into Internet packets.routerA device that forwards data between networks. An IP router forwards data based on IP source and destination addresses.SSIDA Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a wireless local area network. For the wireless devices in a network to communicate with each other, all devices must be configured with the same SSID. This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the wireless Access Point and to the wireless network name. See also Wireless Network Name and ESSID.Subnet MaskA mask used to determine what subnet an IP address belongs to. Subnetting enables a network administrator to further divide an IP address into two or more subnets.An IP address has two components, the network address and the host address. For example, consider the IP address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215) represent the Class B network address, and the second two numbers (017.009) identify a particular host on this network.
NETGEAR Wireless Router Setup Manual4GlossaryFebruary 2005Subnetting enables the network administrator to further divide the host part of the address into two or more subnets. In this case, a part of the host address is reserved to identify the particular subnet. This is easier to see if we show the IP address in binary format. The full address is: 10010110.11010111.00010001.00001001 The Class B network part is: 10010110.11010111 and the host address is 00010001.00001001 If this network is divided into 14 subnets, however, then the first 4 bits of the host address (0001) are reserved for identifying the subnet. The subnet mask is the network address plus the bits reserved for identifying the subnetwork. (By convention, the bits for the network address are all set to 1, though it would also work if the bits were set exactly as in the network address.) In this case, therefore, the subnet mask would be 11111111.11111111.11110000.00000000. It's called a mask because it can be used to identify the subnet to which an IP address belongs by performing a bitwise AND operation on the mask and the IP address. The result is the subnetwork address: Subnet Mask 255.255.240.000 11111111.11111111.11110000.00000000 IP Address 150.215.017.009 10010110.11010111.00010001.00001001 Subnet Address 150.215.016.000 10010110.11010111.00010000.00000000 The subnet address, therefore, is 150.215.016.000. TCP/IPThe main internetworking protocols used in the Internet. The Internet Protocol (IP) used in conjunction with the Transfer Control Protocol (TCP) form TCP/IP.WANWide Area Network. A long distance link used to extend or connect remotely located local area networks. The Internet is a large WAN.WEPWired Equivalent Privacy is a data encryption protocol for 802.11b wireless networks. All wireless nodes and access points on the network are configured with a 64-bit or 128-bit Shared Key for data encryption.Wi-FiA trade name for the 802.11b wireless networking standard, given by the Wireless Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standards group promoting interoperability among 802.11b devices.Wireless Network Name (SSID)Wireless Network Name (SSID) is the name assigned to a wireless network. This is the same as the SSID or ESSID configuration parameter. WPAWi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security enhancements that increase the level of data protection and access control for existing and future wireless LAN systems.
