Wireless-B Broadband RouterChapter 1: IntroductionThe Wireless Router lets you securely share your DSL or Cable ModemInternet connection with all the computers in the house, both wireless andwired. You can connect four computers directly to the Router by Ethernetcables, and daisy-chain out to more hubs and switches to create as big a net-work as you need.Or, use the Router's built-in Wireless Access Point to connect your PC to thenetwork without stringing any wires. Just plug a wireless network adapter intoyour notebook through a PC Card slot, and you're ready to go. Wireless net-working doesn't get any easier.Of course, you can connect more computers to the Router and your high-speedInternet link -- just provide a wired or wireless network adapter for each one.And once your computers are connected to the Router, they can communicatewith each other too, sharing resources like printers and all kinds of files --music, digital pictures, and documents. To protect your data and privacy, all wireless communications can be protect-ed by 128-bit encryption, while the Router helps keep Internet intruders out ofyour computers. It's all easier than you think -- the included Setup Wizardswalk you through configuring the Router, step by step.With the Wireless-B Broadband Router, you're ready to start sharing printers,files, and your Internet connection, the easy way.• 11 Mbps High-Speed Data Transfer Rate with Automatic Fallback• Plug-and-Play Operation Provides Easy Setup• 802.11b, DSSS, 2.4GHz-Compliant• Supports up to 128-bit WEP Encryption Security• Compatible with Virtually All Major Network Operating Systems• Free Driver Upgrades via Web• Remote administration and upgrade feature• Integrated Equalizer Recovers Weak Signals and Enhances Sensitivity• Sturdy Metal Design with Integrated Antenna• Works with All Standard Internet Applications• Clear Channel Assessment Increases Network Throughput• Hardware Buffer Chaining Provides High Performance While Reading andWriting BuffersThe Wireless Broadband RouterFeaturesNetwork Everywhere®SeriesAppendix A: Troubleshooting 45Common Problems and Solutions 45Frequently Asked Questions 57Appendix B: How to Ping Your ISP’s E-mail and Web Addresses 63Appendix C: Configuring Wireless Security 66Configuring Wireless Security in Windows XP 69Appendix D: Finding the MAC Addressand IP Address for Your Ethernet Adapter 74Appendix E: Glossary 78Appendix F: Specifications 87Environmental 87Appendix G: Warranty Information 88Appendix H: Contact Information 891
Wireless-B Broadband RouterNetwork Everywhere®Series2Dynamic IP AddressesA dynamic IP address is automatically assigned to a device on the network,such as PCs and print servers. These IP addresses are called “dynamic”because they are only temporarily assigned to the PC or device. After a certaintime period, they expire and may change. If a PC logs on to the network (or theInternet) and its dynamic IP address has expired, the DHCP server will assignit a new dynamic IP address.For DSL users, many ISPs may require you to log on with a user name andpassword to gain access to the Internet. This is called “Point to Point Protocolover Ethernet” or PPPoE. PPPoE is similar to a dial-up connection but does nothave a phone number to dial into, and PPPoE is a dedicated high-speed con-nection. PPPoE also will provide the Router with a dynamic IP address toestablish a connection to the Internet.DHCP (Dynamic Host Configuration Protocol) ServersDHCP frees you from having to assign IP addresses manually every time a newuser is added to your network. PCs and other network devices using dynamicIP addressing are assigned a new IP address by a DHCP server. The PC or net-work device obtaining an IP address is called the DHCP client. The Router’sInternet port is, by default, set as a DHCP client.DHCP servers can either be a designated PC on the network or another networkdevice, such as the Router. By default, a DHCP server is enabled on yourRouter’s LAN ports. If you already have a DHCP server running on your net-work, you must disable one of the two DHCP servers. If you run more than oneDHCP server on your network, you will experience network errors, such asconflicting IP addresses. To disable the Router’s DHCP function, see theDHCP section in Chapter 5: The Router’s Web-Based Utility.NNoottee::Even if you assign a static IP address to a PC, other PCs can still useDHCP’s dynamic IP addressing, as long as the static IP is not within theDHCP range of the LAN IP Address.If the Router’s DHCP function fails to provide a dynamic IP address for anyreason, please refer to Appendix A: Troubleshooting.NNoottee::Since the Router is a device that connects two networks, it needs twoIP addresses—one for the LAN side, and one for the Internet side. In thisUser Guide, you’ll see references to the “Internet IP address” and the “LANIP address.”Since the Router has firewall security (NAT), only the Router’s Internet IPaddress can be seen from the Internet.However, even the Internet IP address can be blocked, so that the Router andnetwork seem invisible to the Internet—This is shown in the Filters section in“Chapter 5: The Routers Web-Based Utility”. Simply put, a router is a network device that connects two networks together. In this instance, the Router connects your Local Area Network (LAN), or thegroup of PCs in your home or office, to the Wide Area Network (WAN) that isthe Internet. The Router processes and regulates the data that travels betweenthese two networks. Think of the Router as a network device with two sides. The first side is madeup of your private Local Area Network (LAN) of PCs. The other, public sideis the Internet, or the Wide Area Network (WAN), outside of your home oroffice. The Router’s firewall (NAT) protects your network of PCs so users on the pub-lic, Internet side cannot “see” your PCs. This is how your LAN, or network,remains private. The Router protects your network by inspecting the first pack-et coming in from the Internet port before delivery to the final destination onthe LAN port. The Router inspects Internet port services like the web server,ftp server, or other Internet applications, and, if allowed, it will forward thepacket to the appropriate PC on the LAN side.What’s an IP Address?IP stands for Internet Protocol. Every device on an IP-based network, includ-ing PCs, print servers, and routers, requires an IP address to identify its “loca-tion,” or address, on the network. This applies to both the Internet and LANconnections.There are two ways of assigning an IP address to your network devices. Static IP AddressesA static IP address is a fixed IP address that you assign manually to a PC orother device on the network. Since a static IP address remains valid until youdisable it, static IP addressing insures that the device assigned it will have thatsame IP address until you change it. Static IP addresses are commonly usedwith network devices such as server PCs or print servers.If you use the Router to share your cable or DSL Internet connection, contactyour ISP to find out if they have assigned a static IP address to your account.If so, you will need that static IP address when configuring the Router. You canget the information from your ISP.IP AddressesAn Introduction to LANs and WANs3

It will stop blink-ing after completing the diagnosis. If this LED blinks formore than five seconds, refer to the TroubleshootingAppendix.Ethernet Green. This LED serves two purposes. When this LED is litcontinuously, this indicates that the Router is connected to adevice through the corresponding port (1, 2, 3, or 4). A blink-ing LED indicates that the Router is actively sending orreceiving data over that port. The Router’s LEDsTThhee RReesseett BBuuttttoonnPressing the Reset Button and holding it in for a few seconds will clear allof the Router’s data and restore the factory defaults. This should be doneonly if you are experiencing heavy routing problems, and only after youhave exhausted all of the other troubleshooting options. By resetting theRouter, you run the risk of creating conflicts between your PCs’ actual IPAddresses and what the Router thinks their IP Addresses should be. Youmay be forced to reboot each network PC.If the Router locks up, simply press the reset button or power it down forthree to five seconds by removing the power cable from the Router’sPower Port. Leaving the power off for too long could result in the loss ofnetwork connections.Figure 1-2The Router’s rear panel (as shown in Figure 1-1) is where all of its connectionsare made.Internet The Internet Port is where you will connect your cable orDSL modem with an Ethernet cable. Your modem con-nection will not work from any other port. Ports 1, 2, 3, 4 These four LAN (Local Area Network) ports are whereyou will connect networked devices, such as PCs, printservers, and any other Ethernet devices you want to puton your network. Power The Power Port is where you will connect the includedAC Power adapter.Figure 1-1The Router’s Ports
Wireless-B Broadband Router7Chapter 2: Planning Your WirelessNetworkA wireless LAN is exactly like a regular LAN, except that each computer in theLAN uses a wireless adapter to connect to the network through a wireless con-nection. Computers in a wireless LAN must be configured to share the sameradio channel.The wireless adapter provides LAN access for wireless workstations. An inte-grated wireless and wired LAN is called an Infrastructure configuration. Agroup of wireless adapter users and this Router compose a Basic Service Set(BSS). Each PC equipped with a wireless adapter in a BSS can talk to anycomputer in a wired LAN infrastructure via this Router.An infrastructure configuration extends the accessibility of a PC with a wire-less adapter to a wired LAN, and doubles the effective wireless transmissionrange for two PCs equipped with a wireless adapter Infrastructure mode also supports roaming capabilities for mobile users. Morethan one BSS can be configured as an Extended Service Set (ESS). This con-tinuous network allows users to roam freely within an ESS. All PCs that areequipped with a wireless adapter, and are within one ESS, must be configuredwith the same ESS ID.Before enabling an ESS with roaming capability, it is recommended to select afeasible radio channel and optimum Router position. Proper positioning com-bined with a clear radio signal will greatly enhance performance.RoamingNetwork TopologyNetwork Everywhere®Series6The Internet indicators, shown in Figure 1-2, show the status of informationbeing transmitted to and from the Internet.Internet Green.

Connect the Power Adapter (included) to the Router’s Power port and plugthe other end into a power outlet.• The Power LED will blink green as soon as the power adapter is con-nected.5. Power on the cable or DSL modem. Verify that the power is on by checkingthe Internet LED in the Internet column on the front of the Router. TheLink LED will be illuminated if the power is on and the modem is ready.6. Press the Reset button on the back of the Router. Hold the button in for threeseconds. This restores the Router’s default settings.7. Power on your PC.The Router is now connected.Continue to the next chapter to configure your PCs.For Wireless Connections: In addition to accessing the Router through anEthernet connection, a wireless connection can be used to access the Router.After powering on the Router and connecting it to your modem, enter theRouter’s IP Address in the Address field of your wireless PC’s web-browser asfollows: http://192.168.1.1 and press Enter.IImmppoorrttaanntt:: The Router is configured by default to work out of the box withall Network Everywhere Wireless Adapters. If you have changed thedefaults on your Network Everywhere Wireless Adapters, or are usingother wireless adapters, you must temporarily change your wirelessadapter settings to: (SSID = wireless) in order to initially access the Routerwirelessly. After you have accessed the Router with the default settings,you can change the Router’s settings to coincide with your Network set-tings and reset your adapters.IImmppoorrttaanntt:: Some ISPs—most notably some cable providers—configuretheir networks so that you do not have to enter a full Internet address intoyour web browser or e-mail application to reach your home page orreceive your e-mail. If your Internet home page address is something verysimple, such as “www”, rather than “www.networkeverywhere.com”, oryour e-mail server’s address is something similar to “e-mail” or “pop3”,rather than “pop.mail.networkeverywhere.com”, you won’t be able toproperly configure the Router until you determine the actual Internetaddresses of your Web and e-mail connections.You mmuussttobtain this information prior to connecting the Router to your net-work. You can obtain this information by contacting your ISP.Chapter 3: Connecting the RouterBefore plugging everything together, it’s always a good idea to have everythingyou’ll need to get the Router up and running. Depending upon how you con-figure the Router in Chapter 5: The Router’s Web-based Utility, you may needsome of the following values from your ISP:When connecting through a Static IP connection, be sure to have 1) Yourbroadband-configured PC’s fixed Internet IP Address, 2) Your broadband-configured PC’s Computer Name and Workgroup Name, 3) Your SubnetMask, 4) Your Default Gateway, and 5) Your Primary DNS IP address.When connecting through a PPPoE connection, be sure to have 1) YourPPPoE User Name and 2) Your PPPoE Password.The installation technician from your ISP should have left this information withyou after installing your broadband connection. If not, you can call your ISP torequest the data.Once you have the above values, you can begin the Router’s installation andsetup.Once you are sure that you have the above values on hand, you can begin theInstallation and Setup of the Router.1. Power everything down, including your PCs, your cable or DSL modem andthe Router.2. Connect an Ethernet cable from one of your PC’s Ethernet ports to one of theRouter’s Ethernet ports. Do the same with all the PCs you wish to connect tothe Router. In addition to accessing the Router through an Ethernet connection, a wire-less connection can be used to access the Router. See the “For WirelessConnections” note that follows these connection instructions.3. Connect another Ethernet cable from your cable or DSL modem to theRouter’s Internet port.Before You StartConnecting Your Hardware Together and Booting Up

They include the following:• FTP (File Transfer Protocol) A protocol used to transfer files over aTCP/IP network (Internet, UNIX, etc.). For example, after developing theHTML pages for a website on a local machine, web developers typicallyupload the files to the web server using FTP. FTP includes functions to logonto the network, list directories, and copy files. FTP operations can be per-formed by typing commands at a command prompt or via an FTP utilityrunning under a graphical interface such as Windows. FTP transfers canalso be initiated from within a web browser by entering the URL precededby ftp://.• Telnet A terminal emulation protocol commonly used on Internet andTCP/IP-based networks. It allows a user at a terminal or computer to logonto a remote device and run a program.• SMTP (Simple Mail Transfer Protocol) The standard e-mail protocol onthe Internet. It is a TCP/IP protocol that defines the message format and themessage transfer agent (MTA), which stores and forwards the mail. • DNS (Domain Name System) The way that Internet domain names arelocated and translated into IP addresses. A domain name is a meaningfuland easy-to-remember “handle” for an Internet address.• TFTP (Trivial File Transfer Protocol) A version of the TCP/IP FTP proto-col that has no directory or password capability.• Finger A UNIX command widely used on the Internet to find out infor-mation about a particular user, such as his or her telephone number, whetherthe user is currently logged on, and the last time the user was logged on. Theperson being “fingered” must have placed his or her profile on the systemin order for the information to be available. Fingering requires entering thefull user@domain address, for example, name@universityname.edu.• HTTP (HyperText Transport Protocol) The communications protocol usedto connect to servers on the World Wide Web. Its primary function is toestablish a connection with a web server and transmit HTML pages to theclient web browser. • POP3 (Post Office Protocol 3) A standard mail server commonly used onthe Internet. It provides a message store that holds incoming e-mail untilusers log on and download it. POP3 is a simple system with little selectivi-ty. All pending messages and attachments are downloaded at the same time.POP3 uses the SMTP messaging protocol. (SMTP may also need to be for-warded.)

TheRouter, using the RIP protocol, determines the network packets’ route based onthe fewest number of hops between the source and the destination. The RIP pro-tocol regularly broadcasts routing information to other routers on the network.To set up Dynamic Routing:1. Choose the correct Working Mode. Gateway mode should be used if theRouter is hosting your network’s connection to the Internet. Router modeshould be selected if the Router exists on a network with other routers. InRouter Mode, any computer connected to the Router will not be able to con-nect to the Internet unless you have another router functioning in theGateway mode.2.

Wireless-B Broadband Router39Network Everywhere®Series38To delete a Static Routing entry, select an entry, and click the Delete thisentry button.2. Enter the following data to create a new static route.Destination LAN IP: The Destination LAN IP is the address of the remotenetwork or host to which you want to assign a static route. Enter the IPaddress of the host for which you wish to create a static route here. If youare building a route to an entire network, be sure that the network portionof the IP address is set to 0. For example, the Router’s standard IP addressis 192.168.1.1. Based on this address, the address of the routed network is192.168.1.x, with the last digit “x” determining the Router’s place on thenetwork. Therefore you would enter the IP address 192.168.1.0 if you want-ed to route to the Router’s entire network, rather than just to the Router.Subnet Mask: The Subnet Mask determines which portion of an IPaddress is the network portion, and which portion is the host portion. Take,for example, a network in which the Subnet Mask is 255.255.255.0. Thisdetermines (by using the values 255) that the first three numbers of a net-work IP address identify this particular network, while the last digit (from1 to 254) identifies the specific host.Default Gateway: This IP address should be the IP address of the gatewaydevice that allows for contact between the Router and the remote networkor host.Hop Count: This determines the maximum number of steps between net-work nodes that data packets will travel. A node is any device on the net-work, such as PCs, print servers, routers, etc. The maximum metric, ormeasure, of hops is 15.Interface: Select LAN or WA N , depending on the location of the staticroute’s final destination.To apply any of the settings you’ve changed on this page, click the Apply but-ton.

This value should remain at its default setting of 2,346.Should you encounter inconsistent data flow, only minor modifications arerecommended.• Fragmentation Threshold. This value indicates how much of the Router’sresources are devoted to recovering packet errors. The value should remainat its default setting of 2,346. If you have decreased this value and experi-ence high packet error rates, you can increase it again, but it will likelydecrease overall network performance. Only minor modifications of thisvalue are recommended.• DTIM Interval. This value indicates the interval of the Delivery TrafficIndication Message (DTIM). A DTIM field is a countdown field informingclients of the next window for listening to broadcast and multicast mes-sages. When the Router has buffered broadcast or multicast messages forassociated clients, it sends the next DTIM with a DTIM Interval value.Clients for the Router hear the beacons and awaken to receive the broadcastand multicast messages. • Basic Rates. The basic transfer rates should be set depending on the speedof your wireless network. You must select 1-2 (Mbps) if you have older802.11 compliant equipment on your network, such as wireless adaptersthat support only 1 or 2 Mbps. Selecting 1-2 (Mbps), however, does notlimit the basic transfer rates of faster adapters.• TX Rates. Select all the rate at which you wish the Router to communicatewithin your wireless network. • Preamble Type. The preamble defines the length of the CRC block forcommunication between the Router and the roaming Network Card. (Highnetwork traffic areas should use the shorter preamble type.) Select theappropriate preamble type and click the Apply button to set it.• Authentication Type. You may choose between Open System, SharedKey, and Both. The Authentication Type default is set to Open System, inwhich the sender and the recipient do NOT share a secret key. Each partygenerates its own key-pair and asks the receiver to accept the randomly-generated key. Once accepted, this key is used for a short time only. Thena new key is generated and agreed upon. Shared Key is when both thesender and the recipient share a secret key.43Network Everywhere®Series42Before making any changes to the Wireless tab, shown in Figure 5-19, pleasecheck the wireless settings for all your wireless PCs, as these changes will alterthe Router’s effectiveness.

If youcan’t find an answer here, check the Network Everwhere website at www.net-workeverywhere.com.1. I need to set a static IP address on a PC.The Router, by default, assigns an IP address range of 192.168.1.100 to192.168.1.149 using the DHCP server on the Router. To set a static IP address, youcan only use the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to192.168.1.254. Each PC or network device that uses TCP/IP must have a uniqueaddress to identify itself in a network. If the IP address is not unique to a network,Windows will generate an IP conflict error message. You can assign a static IPaddress to a PC by performing the following steps:For Windows 98 SE and Me:A. Click Start, Settings, and Control Panel. Double-click Network.B. In The following network components are installed box, select the TCP/IP->associated with your Ethernet adapter. If you only have one Ethernet adapterinstalled, you will only see one TCP/IP line with no association to an Ethernetadapter. Highlight it and click the Properties button.C. In the TCP/IP properties window, select the IP address tab, and select Specifyan IP address. Enter a unique IP address that is not used by any other com-puter on the network connected to the Router. You can only use an IP addressin the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to192.168.1.254. Make sure that each IP address is unique for each PC or net-work device.D. Click the Gateway tab, and in the New Gateway prompt, enter 192.168.1.1,which is the default IP address of the Router. Click the Add button to acceptthe entry.E.
