4IntroductionCongratulations on your purchases of the GemTek Wireless BroadbandRouter. Your Wireless Broadband Router enables you to share your DSL orCable Internet connection with computers on your network. This guide willexplain the features and functions of the Wireless Broadband Router to helpyou get the most out of your Internet experience.GemTek’s Wireless Broadband Router allows LAN users to share asingle Internet Connection while providing the safety and security of portblocking, packet filtering, and a natural firewall. Static address support,integrated DHCP, PPPoE, and device name support will allow it to connectto nearly any broadband provider whether Cable or DSL based, and at thesame time simplify local area network settings.The Wireless Broadband Router provides two levels of security support.First, it masks local users’ IP addresses from others on the Internet making itmuch more difficult for a hacker to target a machine on your network.Secondly, it can block and redirect certain ports to limit the services thatoutside users can access. Specific ports can be opened to ensure that gamesand other Internet applications will run properly.The Broadband Router provides special pass through support forcommon VPN implementations. The Virtual Server feature allows you toexpose HTTP, FTP, Game Servers and other local services to be accessibleto Internet users located outside of the LAN. The User-DefinableApplication Sensing Tunnel feature allows you to define the attributes tosupport special applications requiring multiple connections, such as Internetgaming, video conferencing, and Internet telephony. A DMZ setting can beapplied to a single client behind the Broadband Router to expose it to the
5Internet and ensure complete Internet application compatibility even ifspecific ports are not known.Unlike proxy server or NAT software that requires the software serverto remain visible on the Internet, no local computers are directly externallyvisible when using the Broadband Router. Also the Broadband Router, likebroadband, is always on, removing the need to constantly boot a softwareserver when access is desired from a client.Integrated DHCP services allow up to 252 users to get their IP addressautomatically on boot up from the Broadband Router. Client machinesrequire no software, simply set them to accept a dynamically assigned IPaddress and reboot. Each time they are powered up the Broadband Routerwill recognize them and set their IP address to instantly connect them to theLAN.Package ContentsThe GemTek WX-2211 package should include the following items. WX-2211 Broadband router User’s Manual Quick Install Guide Power Adapter CAT-5 UTP Cable
6Introduction to Broadband Router TechnologyA router is a device that forwards data packets from a source to adestination. Routers work on OSI layer 3, which forwards data packets usingan IP addresses and not a MAC address. A router will forward data from theInternet to a particular computer on your LAN.The information that makes up the Internet gets moved around usingrouters. When you click on a link on a web page, you send a request to aserver to show you the next page. The information that is sent and receivedfrom your computer is moved from your computer to the server usingrouters. A router also determines the best route that your information shouldfollow to ensure that the information is delivered properly.A router controls the amount of data that is sent through your networkby eliminating information that should not be there. This provides securityfor the computers behind your router because computers from the outsidecannot access or send information directly to any computer on your network.The router determines which computer the information should be forwardedto and sends it. If the information is not intended for any computer on yournetwork, the data is discarded. This keeps any unwanted or harmfulinformation from accessing or damaging your network.Introduction to FirewallsA firewall is a device that sits between your computer and the Internetthat prevents unauthorized access to or from your network. A firewall can bea computer using firewall software or a special piece of hardware builtspecifically to act as a firewall. In most circumstances, a firewall is used toprevent unauthorized Internet users from accessing private networks such ascorporate LAN’s and Intranets.
7A firewall watches all of the information moving to and from yournetwork and analyzes each piece of data. Each piece of data is checkedagainst a set of criteria that the administrator configures. If any data does notmeet the criteria, that data is blocked and discarded. If the data meets thecriteria, the data is passed through. This method is called packet filtering.A firewall can also run specific security functions based on the type ofapplication or type of port that is being used. For example, a firewall can beconfigured to work with an FTP or Telnet server. Or a firewall can beconfigured to work with specific UDP or TCP ports to allow certainapplications or games to work properly over the Internet.Introduction to Local Area NetworkingLocal Area Networking (LAN) is the term used when connectingseveral computers together over a small area such as a building or group ofbuildings. LAN’s can be connected over large areas. A collection of LAN’sconnected over a large area is called a Wide Area Network (WAN).A LAN consists of multiple computers connected to each other. Thereare many types of media that can connect computers together. The mostcommon media is CAT5 cable; UTP or STP twisted pair wire. On the otherhand, wireless networks do not use wires; instead they communicate overradio waves. Each computer must have a Network Interface Card (NIC),which communicates the data between computers. A NIC is usually a10Mbps network card, 10/100Mbps network card, or a wireless networkcard.Most networks use hardware devices such as hubs or switches that eachcable can be connected to in order to continue the connection betweencomputers. A hub simply takes any data arriving through each port and
8forwards the data to all other ports. A switch is more sophisticated, in that aswitch can determine the port that each piece of data is supposed to bedelivered to. A switch minimizes network traffic and speeds up thecommunication over a network.Networks take some time in order to plan and implement correctly.There are many types of scenarios to consider which could affect theoperability of a network.Introduction to Virtual Private NetworkingVirtual Private Networking (VPN) uses a publicly wired network (theInternet) to securely connect two different networks as if they were the samenetwork. For example, an employee can access the corporate network fromhome using VPN, allowing the employee to access files and printers. Hereare several different implementations of VPN that can be used.Point-to-Point Tunneling Protocol (PPTP)PPTP uses proprietary means of connecting two private networks over theInternet. PPTP is a way of securing the information that is communicatedbetween networks. PPTP secures information by encrypting the data insideof a packet.IP Security (IPSec)IPSec provides a more secure network-to-network connection across theInternet or a Wide Area Network (WAN). IPSec encrypts all communicationbetween the client and server whereas PPTP only encrypts the data packets.Both of these VPN implementations are used because there is not a
9standard for VPN server software. Because of this, each ISP or business canimplement their own VPN network making interoperability a challenge.Introduction to Wireless NetworkingGemTek wireless products are based on industry standards to provideeasy to use and compatible high-speed wireless connectivity within yourhome or business. Strictly adhering to IEEE 802.11b the GemTek wirelessfamily of products will allow you to access the data you want, when andwhere you want it. No longer will you be tethered to a workstation or forcedto run new wiring. You will be able to enjoy the freedom that wirelessnetworking delivers.Standards Based TechnologyBased on IEEE 802.11b, GemTek Air products can operate at themaximum data rate of 11 Megabits per second. This means you will be ableto transfer large files quickly or even watch a Movie in MPEG format overyour network without noticeable delays. This technology works by usingmultiple frequencies in the 2.4GHz range utilizing Direct Sequence SpreadSpectrum (DSSS) technology. GemTek Air products will automaticallysense the best possible connection speed to ensure the greatest speed andrange possible with the technology.Installation ConsiderationsDesigned to go up to 100 meters indoors and up to 300 meters outdoors,GemTek Air lets you access your network from anywhere you want. Keep inmind, however, that the number of walls, ceilings or other objects that thewireless signals must pass thru will limit range. Typical ranges vary
10depending on the types of materials and background RF noise in your homeor business. The key to maximizing range is to follow these basic principles:1. Keep the number of walls and ceilings to a minimum - Each wall orceiling can reduce your GemTek Air Wireless products range from 1-30meters. Position your Access Points, Residential Gateways, andComputers so that the number of walls or ceilings is minimized.2. Be aware of the direct line between Access Points, Residential Gateways,and Computers - A wall that is .5 meter thick, at a 45 degree angleappears to be almost 1 meter thick. At a 2 degree angle it looks over 14meters thick! Try to make sure that the AP and Adapters are positionedso that the signal will travel straight through a wall or ceiling for betterreception.3. Building Materials make a difference - A solid metal door or aluminumstuds may have a negative effect on range. Again, try to position AccessPoints, Residential Gateways, and Computers so that the signal passesthrough drywall or open doorways and not other materials.4. Make sure that the antenna is positioned for best reception by using thesoftware signal strength tools included with your product.5. Keep your product away (at least 1-2 meters) from electrical devices thatgenerate RF noise, like microwaves, Monitors, electric motors, etc.For the average American 4-bedroom home, range should not be aproblem. If you experience low or no signal strength in areas of yourhome that you wish to access, consider positioning the Access Point in alocation directly between the Residential Gateways and/or Computersthat will be connected. Additional Access Points can be connected toprovide better coverage in rooms where the signal does not appear asstrong as desired.

This section will discuss the WebConfiguration interface and how to use different options and settings.Although you can change the IP address of the WX-2211 to meet yourneeds, this manual will assume that the defaults are left in place. This meansthat the IP address of your WX-2211 will be 192.168.0.1. If you havechanged the IP address scheme, please substitute 192.168.0.1 with the IPaddress scheme that you have chosen.Start-up and Log inIn order to configure the WX-2211, you must use your web browserand manually input 192.168.0.1 into the Address box and press Enter. TheMain Page will appear. The Device Information and Device Status screenscan be seen without logging into the WX-2211. However, when the SetupWizard, Basic Setup, Advanced Settings and System Tools buttons arepressed, the log in screen will be shown.
14In order to configure the WX-2211 you must input the user-name intothe User Name box. Enter the password into the Password box and pressthe OK button. The default User Name is “admin”. There is no defaultpassword, leave the Password field blank.Once you have logged-in as administrator, it is a good idea to changethe administrator password to ensure a secure connection to the WX-2211.The Advanced Settings section described later in this manual describes howto change the password.Once you have input the correct password and logged-in, the screenwill change to the Main Page screen.If you are having problems logging in and you are sure that thepassword you are using is correct, check the top right-hand corner of yourkeyboard to make sure that the Caps Lock light is not on.
15Main PageThe Main Page screen provides links to the main sections of the webconfiguration interface.Setup WizardThe Setup Wizard is a step-by-step guide to configuring the WX-2211to work with your ISP provider. Please refer to the quick install guide foradditional instructions.
16Device InformationThe Device Information screen displays the basic information of yourWX-2211.The Device Name is the same as the Computer Name that was set inthe Setup Wizard.The IP Address is the IP Address assigned to LAN side of your WX-2211.The Private LAN Mac Address the Mac Address assigned to the LANside of your WX-2211.The Public WAN (Cable/DSL) Mac Address is the Mac Addressassigned to the WAN port of the WX-2211. This Mac Address may be usedby some cable modem connections.The Firmware Version is the current firmware version used by theWX-2211.
17Device StatusThe Device Status screen displays a graphical representation of yourcurrent configuration. The left side of the screen shows your connectioninformation in regards to WAN and LAN IP Address information. The rightside displays the connection status of each device. This means that there is a connection.
18 This means that there is not a connection.The DHCP Log displays information about each IP Address assigned toa computer using the DHCP server built-in to the WX-2211.Basic SetupThe Basic Setup screen enables you to change basic settings related toaccessing the Internet. All of the settings covered in the Basic Setup sectionare covered in the Setup Wizard.The Computer Name is used to give a name to your connection if youare using a Cable modem.
19The Domain Name (host name) is the name given to you by your ISPprovider if you using the @Home cable Internet service.Choose the Type of Connection you use by selecting Dynamic IP, StaticIP, or PPPoE.Select Dynamic IP if your ISP has not given you a unique IP addressand you receive an automatic IP address each time you connect to your ISP.The rest of the settings related to your connection are retrievedautomatically each time you connect to the Internet.Select Static IP if your ISP assigns you an IP address. This means thatyour ISP has given you an IP address that you will use to connect to theInternet through their service. If you select Static IP, you will need to enterthe correct values for the IP Address, Subnet Mask and Gateway in the fieldsprovided.Select PPPoE if your ISP uses the Point-to-Point over Ethernetprotocol to authenticate a username and password and then automaticallyassign you an IP Address. PPP over Ethernet (PPPoE) is a non-standardmethod of connecting to your ISP to obtain an IP address. It relies upon asoftware client that is provided by the ISP. If you have a broadbandconnection and login to your ISP like you would do with a dial-in modem,then you are probably using PPPoE. If you are simply connected to theInternet when you turn on your computer, you probably are not. The safestway to check is to call your ISP or read the documentation provided whenyou signed up for your Internet service. If you select PPPoE, you will needto enter the correct values for your User Name and Password in the fieldsprovided.The DNS section needs to be set to the correct option in order for theWX-2211 to resolve domain name information in URL’s.
20Select Dynamic DNS if your ISP provides the DNS information muchin the same way as you receive an IP Address.Select Static DNS if you were given the DNS server information whenyou signed with your ISP.Click on the Save & Restart button to save your settings.
21Advanced SettingsDHCP Server SettingsBy default, the Wireless Broadband Router has DHCP server enabled toassign an IP address ranging from 192.168.0.100 to 192.168.0.199. Inaddition, the router is capable of reserving up to four IP addresses within thelocal network for mail, web, or ftp server.
22Virtual Server SettingsSpecific application support is enabled in Virtual Server Settings underAdvanced Settings. Click on the arrow to select the common applicationssuch as FTP, Web server, and mail server. The WX-2211 WirelessBroadband Router will detect and automatically open outgoing portsrequired by most applications and games. However, some games andapplications such as Netmeeting will require that the computer be exposedin the DMZ zone to allow incoming ports required by the application. Clickon the “Submit” button to save your settings.DMZThe Virtual Server Settings under Advanced Settings also enables onecomputer to have full access to the Internet without the protection of the
23firewall. This allows a computer to be exposed to unrestricted two-waycommunication outside of your network.To enable DMZ, click the checkbox to the left and select “All”. Thentype the IP address of the selected computer in the box provided. Click the“Submit” button to save your changes.Only one computer can use DMZ at a time. Please note that enablingDMZ removes the protection of the firewall, which exposes the computer tointrusion.Use DMZ only when needed and not for extended periods of time.In some circumstances with gaming, enabling DMZ may help the gamecontact the maximum number of servers, which can improve ping times.Once the game connects to the game server, disable DMZ to ensure properfirewall protection.
24Static RoutingIn Static Routing, the user has the ability to add a static route to therouting table by simple entering the destination IP, subnet mask, andgateway. Clicking on “Add” and then “Submit” which requires a restart forthe IP address to be incorporated into the routing table.
25Dynamic SettingsBy default, the Wireless Broadband Router will not send or receive anyrouting Internet protocols (RIP) to update the routing table. However, theuser can enable the Wireless Broadband Router to automatically send andreceive RIP packets to establish routes for commonly used paths.
26Modem String SettingsMost dial-up modems are compatible with the standard modem strings.However for modems that require special modem strings, the user can enterthe information in this screen.

After eachproblem description, a possible cause and problem resolution is provided. Ifthis section does not help you fix the problem, go to the GemTek web site(www.dlink.com) for additional troubleshooting tips. If neither of thesehelps, please contact GemTek Technical Support for additional help. Thephone numbers for Technical Support are in the appendix of this manualunder GemTek Office Information.Basic FunctionsMy Broadband Router will not turn on. No LED’s light up.Cause: The power is not connected or the power switch is set to “Off”.Resolution: Connect the power adapter to your Broadband Router and plug it into thepower outlet. Make sure that the power switch is set to “On”.Note: Only use the power adapter provided with your Broadband Router.Using any other adapter may damage your Broadband Router.LED’s don’t follow the correct boot-up sequence as stated in the QuickInstall Guide.Cause: The unit’s firmware is corrupt.
35 The unit is not receiving the correct voltage from the power supply.Resolution: Download and upgrade the latest firmware. Make sure the correct firmware has been used while upgrading. Use onlythe firmware provided on GemTek’s web or FTP sites. Use only the power adapter provided.The Link or Act LED’s do not turn on.Cause: The network cable is not connected. The network cable is connected but not the right type, whether it is patchor straight-through.Resolution: Make sure that both ends of the cable are connected. Try using another cable. If you are using a straight-through cable, try a patch cable and vice-versa.Sometimes my Broadband Router stops working or locks up.Cause: Someone has attempted to hack into someone on your LAN. The Broadband Router has detected harmful data trying to access yourLAN. The NAT table is full.Resolution: Reboot the Broadband Router by turning the power to the unit off andthen on again. Some types of hacker tools use very non-standard data
36streams. Some of these streams may cause the Broadband Router to lockup. When the Broadband Router locks up, it will not affect thecomputers attached to it. You may need to restart the client computers toregain Internet access.Although sometimes inconvenient, a lock-up is an indication of anattack. Part of the design of the Broadband Router is to act as a decoy forsuch traffic. If your computer locks up, you may have lost changes toopen files, data, and/or corrupted your operating system or hard drive.If you are currently experiencing frequent lock-ups, you may wish toupgrade the firmware.LAN Connection ProblemsI can’t access my Broadband Router.Cause: The unit is not turned on. There is not a network connection. The computer you are using does not have a compatible IP Address.Resolution: Make sure your Broadband Router is turned on. Make sure that there is a physical connection between your computerand the Broadband Router and that the Link light is on. Use the WINIPCFG utility described in the appendix to make sure thatyour computer has a compatible IP Address. If your IP Address is not setcorrectly and you are using DHCP, use WINIPCFG to renew your IPAddress. Otherwise, make correct changes to your Windows networksettings. Make sure that the IP Address used on your computer is set to
37the same subnet as the Broadband Router. For example, if the BroadbandRouter is set to 192.168.0.1, change the IP address of your computer to192.168.0.15 or another unique IP Address that corresponds to the192.168.0.X subnet. Follow the instructions outlined in the Appendix section labeled“Console Mode” to check the basic settings of your Broadband router.You can verify the IP Address of the Broadband Router to make sure thatyour computers IP Address are set correctly. Use the Reset button located on the front of your Broadband Router torevert to the default settings.I can’t connect to other computers on my LAN.Cause: The IP Addresses of the computers are not set correctly. Network cables are not connected properly. Windows network settings are not set correctly.Resolution: Make sure that each computer has a unique IP Address. If using DHCPthrough the Broadband Router, make sure that each computer is set to“Obtain an IP Address automatically” and restart the computer. Use theWINIPCFG and PING utilities described in the appendix to make surethat you can connect to each computer. Make sure that the Link LED is on. If it is not, try a different networkcable. Check each computer for correct network settings.
38ISP Connection ProblemsI can access the Broadband Router, but I can’t connect to my ISP.Cause: Your DSL or Cable modem is not functioning correctly. The cable is connected from the WAN port of the Broadband Router toyour DSL or Cable modem. The wrong connection type is used in Setup. The username and password is not input correctly. If using @Home service, the computer name is not input correctly. Your ISP may only allow one MAC address to access the Internet. Your ISP may only allow one computer to access their service.Resolution: Make sure that your DSL or Cable modem is running correctly andconnected to the WAN port of the Broadband Router. Make sure that the right connection type is used in the webconfiguration. Make sure that the username and password used in the connection type iscorrect. If using @Home, make sure that the computer name is input correctly. Clone the MAC address using the web configuration interface. Some ISP's do not care if you share your broadband connection amongmultiple users. Other ISP's will explicitly restrict this type of activity inyour service contract. It is important that you verify that you are inaccordance with your service agreement before sharing Internet access.
39Internet Application ProblemsMy online game does not work.Cause: The NAT table has filled up. The correct settings have not been used to open the correct ports for yourapplication. The unit has stopped working or crashed.Resolution: If you are trying to connect to game servers and your connection hasstopped working, wait a few minutes or turn the unit off and then onagain. Games send out many requests to many different servers trying tofind the best game server for your connection. When this is done, theNAT table used in the Broadband Router can fill up and stop workingtemporarily. Try using the DMZ host feature while connecting to gameservers and then disabling DMZ while playing the game. Turn the Broadband Router off and then on again to reset the NAT table. Make sure that the correct ports have been opened in order for yourspecific game to operate correctly behind a firewall. Consult your gamedocumentation or contact technical support for your game to obtain thecorrect settings for your game. Some games just won’t operate correctly behind a firewall. In this case,use the DMZ host feature while using the game, then turning DMZ offwhile the game is not being played to ensure proper firewall protection.My E-Mail program doesn’t receive my E-Mail
40Cause: The Domain Suffix is not set correctly.Resolution: Some email applications require you to enter the Domain Suffix whenyou configure your network and TCP/IP settings. The Domain Suffix isthe unique identifier for your email server. The Domain Suffix is the Internet Protocol (TCP/IP) address of theemail server you are using. Your cable modem or DSL provider usuallylists it somewhere on your invoice. The Domain Suffix address shouldappear similar to this: dlink.occa.home.com. Find the Domain Suffix onyour invoice or call your Internet Service Provider (ISP) to obtain it.I can’t connect to AOLCause: Your AOL software is not set correctly to use the Broadband Router.Resolution: Use your AOL software to change the location information to useTCP/IP in the Network field. Leave the phone number blank. Save yoursettings and try to sign on again.If this does not help, make sure that you can access the Internet ingeneral. If you can access the Internet, contact AOL technical support tohelp you configure your AOL software to work correctly with yourBroadband Router.Wireless Troubleshooting
41Can’t access the Broadband Router from a wireless network cardCause: Settings are not the same among each wireless adapter. Out of range. IP Address is not set correctly.Resolution: Make sure that the Mode, SSID, Channel and encryption settings are setthe same on each wireless adapter. The default SSID and Channel thatthe Wireless Broadband Router uses is “default” and “6” respectively. Make sure that your computer is within range and free from any strongelectrical devices that may cause interference. Refer to the section“Introduction to Wireless Networking” for tips to help make a goodconnection. Check your IP Address to make sure that it is compatible with theWireless Broadband Router. The default IP Address of the WirelessBroadband Router is “192.168.0.1”. A compatible IP Address would be“192.168.0.50”.
