Dual-Band Wireless A+B Broadband Router 3What’s an IP Address?IP stands for Internet Protocol. Every device on an IP-based network, includingPCs, print servers, and routers, requires an IP address to identify its “location,” oraddress, on the network. This applies to both the Internet and LAN connections.There are two ways of assigning an IP address to your network devices. You canassign static IP addresses or use the Router to assign IP addresses dynamically.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 ensures that the device assigned it will alwayshave that same IP address until you change it. Static IP addresses must beunique and are commonly used with network devices such as server PCs orprint 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 that information from your ISP.IP AddressesNote: Since the Router is a device that connects two networks, itneeds two IP addresses—one for the LAN, and one for the Internet. Inthis User Guide, you’ll see references to the “Internet IP address” andthe “LAN IP address.”Since the Router uses NAT technology, the only IP address that can beseen from the Internet for your network is the Router’s Internet IPaddress.However, even this Internet IP address can be blocked, so that theRouter and network seem invisible to the Internet—see the BlockWAN Requests description under Filters in “Chapter 6: The Router’sWeb-based Utility.”Instant Wireless®Series2•Compatibility with 802.11a (5GHz) and 802.11b (2.4GHz) Standards•Built-in, 4-Port, 10/100 Switch Supports Wired Ethernet Clients•All Ethernet Ports Support Auto-MDI/MDI-X—No Need for CrossoverCables•Unsurpassed Security Using 802.1x Authentication with up to 152-bit WEPEncryption•Enhanced Security Management Functions: Port Filtering, MAC and IPAddress Filtering, DMZ Hosting, and NAT Technology•Access Your Corporate Network Remotely through Virtual PrivateNetworking (VPN)—Supports IPSec and PPTP Pass-Through•Easily Configurable through a Web Browser—Locally and over the Internet•DHCP Server Capability to Assign IP Addresses Automatically•Supports Static and Dynamic Routing (RIP1 and 2)•Free Technical Support—24 Hours a Day, 7 Days a Week, Toll-Free US Calls•1-Year Limited WarrantySimply 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 Internet. The Router processes andregulates the data that travels between these two networks.The Router’s NAT feature protects your network of PCs so users on the public,Internet side cannot “see” your PCs. This is how your network remains private.The Router protects your network by inspecting every packet coming inthrough the Internet port before delivery to the appropriate PC on your net-work. The Router inspects Internet port services like the web server, ftp server,or other Internet applications, and, if allowed, it will forward the packet to theappropriate PC on the LAN side.Remember that the Router’s ports connect to two sides. The 10/100 LAN portsconnect to the LAN, and the Internet port connects to the Internet. The LANports transmit data at 10 Mbps or 100 Mbps, and the broadband port, orInternet port, transmits data at 10/100 Mbps.The Router’s FunctionsFeatures
Dual-Band Wireless A+B Broadband Router This User Guide covers the steps for setting up a network with the Router. Aftergoing through “Chapter 2: Getting to Know the Dual-Band Wireless A+BBroadband Router,” most users will only need to use the following chapters: •Chapter 3: Connect the RouterThis chapter instructs you on how to connect a cable or DSL modem to theRouter and connect your PC(s) to the Router.•Chapter 4: Configure the PCsThis chapter instructs you on how to configure your PCs to be DHCP clients,if you have previously set static IP addresses on your PCs. •Chapter 5: Configure the Router’s Basic SettingsThis chapter explains how to configure the Router using your web browserand the Router’s web-based utility. You will configure the Router for Internetaccess using the settings provided by your ISP.When you’re finished with these basic steps, you will be ready to connect to theInternet. You can also modify the Router’s settings further; for example, youcan adjust security features and other settings to enable online gaming (see“Chapter 6: The Router’s Web-based Utility”). 5Instant Wireless®Series4Figure 1-1Cable or DSL Modem RouterPC withEthernetAdapterNotebook withWireless AdapterNotebook withWireless AdapterDynamic 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 onto the network (or theInternet) and its dynamic IP address has expired, the DHCP server will auto-matically assign it a new dynamic IP address.DHCP (Dynamic Host Configuration Protocol) ServersPCs and other network devices using dynamic IP addressing are assigned a newIP address by a DHCP server. The PC or network device obtaining an IPaddress is called the DHCP client. DHCP frees you from having to assign IPaddresses manually every time a new user is added to your network. A DHCP server can either be a designated PC on the network or another net-work device, such as the Router. By default, the Router’s DHCP Server func-tion is enabled.If you already have a DHCP server running on your network, you must disableone of the two DHCP servers. If you run more than one DHCP server on yournetwork, you will experience network errors, such as conflicting IP addresses.To disable DHCP on the Router, see the DHCP section in “Chapter 6: TheRouter’s Web-based Utility.” Router Setup OverviewNote: Even if you assign a static IP address to a PC, other PCs canstill use DHCP’s dynamic IP addressing, as long as the static IPaddress is not within the DHCP range of the LAN IP Addresses.If the dynamic IP addressing fails to provide a dynamic IP address,refer to “Appendix A: Troubleshooting.”Note: You should always you run the Setup Wizard CD-ROM to con-figure the Router for Internet access. If you wish to manually config-ure the Router, you may follow the instructions in the QuickInstallation guide or this User Guide.

If the Router is having problems connecting to the Internet, press the Resetbutton for just a moment with a paper clip or a pencil tip. This clears up anyjammed connections, and is similar to pressing the Reset button on your PCto reboot it.This will reboot the Router while keeping all of the Router’s settings.2. If you are experiencing extreme problems with the Router and have tried allother troubleshooting measures, press the Reset Button and hold it down for10 seconds.This will restore factory defaults and clear all of the Router’s settings,including settings such as a new password or wireless settings.Chapter 2:Getting to Know theDual-Band Wireless A+BBroadband RouterThe Router’s ports are located on the Router’s back panel.Internet The Internet port is where you connect your cable orDSL modem through an Ethernet network cable.Your modem connection will not work from anyother port. Ports 1-4 These four LAN (Local Area Network) ports con-nect to network devices, such as PCs, print servers,and network attached storage (NAS). Each of theports will auto-detect whether a straight-through orcrossover cable is plugged into it, so there is no needfor an uplink port. Any one of the four ports canserve as an uplink port to other network devices.Power The Power port is where you will connect the poweradapter. The Router’s Back PanelFigure 2-1

If all of your Link LEDs are not lighting up, make sure that all yourcables are securely plugged in, and that all of your hardware is pow-ered on properly. Verify that the modem is plugged into the Internetport on the Router.Chapter 3:Connect the Router The Router’s setup consists of more than simply plugging hardware together.You will have to configure your networked PCs to accept the IP addresses thatthe Router assigns them (if applicable), and you will also have to configure theRouter with setting(s) provided by your Internet Service Provider (ISP).The installation technician from your ISP should have left the setup informa-tion for your modem with you after installing your broadband connection. Ifnot, you can call your ISP to request that data. Once you have the setup information you need for your specific type of Internetconnection, you can begin installation and setup of the Router.If you want to use a PC with an Ethernet adapter to configure the Router, go to“Wired Connection to a PC and Boot-Up.” If you want to use a PC with a wire-less adapter to configure the Router, go to “Wireless Connection to a PC andBoot-Up.”1. Before you begin, make sure that all ofyour network’s hardware is poweredoff, including the Router, PCs, andcable or DSL modem.2. Connect one end of an Ethernet net-work cable to one of the LAN ports(labeled 1-4) on the back of theRouter, and the other end to anEthernet port on a PC. Repeat this step to connect more PCs, a switch, or other network devices tothe Router.OverviewWired Connection to a PCFigure 3-1
Dual-Band Wireless A+B Broadband Router Chapter 4: Configure the PCsThe instructions in this chapter will help you configure each of your comput-ers to be able to communicate with the Router.To do this, you need to configure your PC’s network settings to obtain an IP (orTCP/IP) address automatically, so your PC can function as a DHCP client.Computers use IP addresses to communicate with the Router and each otheracross a network, such as the Internet. First, find out which Windows operating system your computer is running. Youcan find out by clicking the Start button. Read the side panel of the Start menuto find out which operating system your PC is running.You may need to do this for each computer you are connecting to the Router.The next few pages tell you, step by step, how to configure your network set-tings based on the type of Windows operating system you are using. Make surethat an Ethernet or wireless adapter (also known as a network adapter) has beensuccessfully installed in each PC you will configure. Once you’ve configuredyour computers, continue to “Chapter 5: Configure the Router’s BasicSettings.” 13Instant Wireless®Series12Important: By default Windows 98, 2000, Me, and XP hasTCP/IP installed and set to obtain an IP address automatically.
