• One Windows 98 SE, Millennium, 2000, or XP PC equipped with:
• TCP/IP Protocol,
• Internet Explorer 5.0 or Netscape Navigator 6 for web-based configuration,
• a CD-ROM Drive, and
• an Ethernet Adapter with a UTP CAT 5 Network Cable
• Cable or DSL Modem with Ethernet Connection and Internet Access
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 the group of PCs in your home or office, to the Internet. The Router processes and regulates the data that travels between these two networks.
Think of the Router as a network device with two sides. The first side is made up of your private Local Area Network (LAN) of PCs. The other, public side is the Internet.
The Router’s firewall (NAT) protects your network of PCs so users on the pub­lic, Internet side cannot “see” your PCs. This is how your LAN, or network, remains private. The Router protects your network by inspecting the first pack­et coming in from the Internet port before delivery to the final destination on the LAN port. 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 the appropriate PC on the LAN side.
Minimum Requirements
An Introduction to Routers and Networks
What’s an IP Address?
IP stands for Internet Protocol. Every device on an IP-based network, includ­ing PCs, print servers, and routers, requires an IP address to identify its “loca­tion,” or address, 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.
Static IP Addresses
A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing insures that the device assigned it will have that same IP address until you change it. Static IP addresses are commonly used with network devices such as server PCs or print servers.
If you use the Router to share your cable or DSL Internet connection, contact your 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 can get the information from your ISP.
3
Dynamic IP Addresses
A 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 certain time period, they expire and may change. If a PC logs on to the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address.
For DSL users, many ISPs may require you to log on with a user name and password to gain access to the Internet. This is called “Point to Point Protocol over Ethernet” or PPPoE. PPPoE is similar to a dial-up connection but does not have a phone number to dial into, and PPPoE is a dedicated high-speed con­nection. PPPoE also will provide the Router with a dynamic IP address to establish a connection to the Internet.
DHCP (Dynamic Host Configuration Protocol) Servers
DHCP frees you from having to assign IP addresses manually every time a new user is added to your network. PCs and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP server. The PC or net­work device obtaining an IP address is called the DHCP client. The Router’s Internet port is, by default, set as a DHCP client.
DHCP servers can either be a designated PC on the network or another network device, such as the Router. By default, a DHCP server is enabled on your Router’s LAN ports. If you already have a DHCP server running on your net­work, you must disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable the Router’s DHCP function, see the DHCP section in Chapter 3: Configuring the Router.
IP Addresses
NNoottee::
Since the Router is a device that connects two networks, it needs two IP addresses—one for the LAN side, and one for the Internet side. In this User Guide, you’ll see references to the “Internet IP address” and the “LAN IP address.”
Since the Router has firewall security (NAT), only the Router’s Internet IP address can be seen from the Internet.
However, even the Internet IP address can be blocked, so that the Router and network seem invisible to the Internet—This is shown in the Filters section in “Chapter 5: Using the Routers Web-Based Utility”.
NNoottee::
Even if you assign a static IP address to a PC, other PCs can still use DHCP’s dynamic IP addressing, as long as the static IP is not within the DHCP range of the LAN IP Address.
If the Router’s DHCP function fails to provide a dynamic IP address for any reason, please refer to Appendix A: Troubleshooting.

Pressing the Reset Button and holding it in for a few seconds will clear all of the Router’s data and restore the factory defaults. This should be done only if you are experiencing heavy routing problems, and only after you have exhausted all of the other troubleshooting options. By resetting the Router, you run the risk of creating conflicts between your PCs’ actual IP Addresses and what the Router thinks their IP Addresses should be. You may be forced to reboot each network PC.
If the Router locks up, simply press the reset button or power it down for three to five seconds by removing the power cable from the Router’s Power Port. Leaving the power off for too long could result in the loss of network connections.
In addition to accessing the Router through an Ethernet connection, a wire­less connection can be used to access the Router. See the “For Wireless Connections” section that follows these connection instructions.
3. Connect another Ethernet cable from your cable or DSL modem to the Router’s Internet port (as shown in Figure 2-2).
4. Connect the Power Adapter
(included) to the Router’s Power port (as shown in Figure 2-3) and plug the other end into a power outlet.
The Power LED will illumi­nate green as soon as the power adapter is connected.
5. Power on the cable or DSL modem. Verify that the power is on by checking the Power LED on the front of the Router. The Internet 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 three seconds. 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.

Chapter 2: Connecting the Router

Before plugging everything together, it’s always a good idea to have everything you’ll need to get the Router up and running. Depending upon how you config­ure the Router in Chapter 4: Configuring the Router, you may need some of the following values from your ISP:
When connecting through a Static IP connection, be sure to have 1) Your broadband-configured PC’s fixed Internet IP Address, 2) Your broadband­configured PC’s Computer Name and Workgroup Name, 3) Your Subnet Mask, 4) Your Default Gateway, and 5) Your Primary DNS IP address.
When connecting through a PPPoE connection, be sure to have 1) Your PPPoE User Name and 2) Your PPPoE Password.
The installation technician from your ISP should have left this information with you after installing your broadband connection. If not, you can call your ISP to request the data.
Once you have the above values, you can begin the Router’s installation and setup.
Once you are sure that you have the above values on hand, you can begin the Installation and Setup of the Router.
1. Power everything down, including your PCs, your cable or DSL modem and the Router.
2. Connect an Ethernet cable from one of your PC’s Ethernet ports to one of the Router’s LAN ports (as shown in Figure 2-1). Do the same with all the PCs you wish to connect to the Router.

Chapter 3: Configuring the PCs

These instructions will help you configure each of your computers to commu­nicate with the Router.
To do this, you will need to configure your PC’s network settings to obtain an IP (or TCP/IP) address automatically. Computers use IP addresses to commu­nicate with each other across a network or the Internet.
You will need to know which operating system your computer is running, such as Windows 95, 98, Millennium, 2000, or XP. You can find out by clicking the Start button and then selecting the Settings option. (If your Start menu does­n’t have a Settings option, you’re running Windows XP. You can select the Control Panel directly from the Start Menu.) Then, click Control Panel and double-click the System icon. Click the Cancel button when done.
Once you know which Windows operating system you are running, follow the directions in this step for your computer’s operating system. If you PC is not configured with the TCP/IP protocol, you will 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 TCP/IP set­tings based on the type of Windows operating system you are using. Once you've configured your computers, continue to Chapter 4: Configuring the Router.
1. Click the Start button, click Settings and open the Control Panel. From there, double-click the Network icon to open the Network screen.

For Wireless Connections: In addition to accessing the Router through an Ethernet connection, a wireless connection can be used to access the Router. After powering on the Router and connecting it to your modem, enter the Router’s IP Address in the Address field of your wireless PC’s web-browser as follows: http://192.168.1.1 and press Enter.
IImmppoorrttaanntt::
The Wireless-B Broadband Router is configured by default to work out of the box with all Linksys Wireless Adapters. If you have changed the defaults on your Linksys Wireless Adapters, or are using other wireless adapters, you must temporarily change your wireless adapter settings to: (SSID = linksys) in order to initial­ly access the Router wirelessly. After you have accessed the Router with the default settings, you can change the router settings to coin­cide with your Network settings and reset your adapters.
IImmppoorrttaanntt::
Some ISPs—most notably some cable providers—config­ure their networks so that you do not have to enter a full Internet address into your web browser or e-mail application to reach your home page or receive your e-mail. If your Internet home page address is something very simple, such as “www”, rather than “www.linksys.com”, or your e-mail server’s address is something sim­ilar to “e-mail” or “pop3”, rather than “pop.mail.linksys.com”, you won’t be able to properly configure the Router until you determine the actual Internet addresses of your Web and e-mail connections.

Chapter 5: Using the Router’s Web­Based Utility
For your convenience, an administrative utility has been programmed into the Router. This chapter will explain all of the functions in this utility. All router­based administrative tasks are performed through this web utility. The web util­ity can be accessed by any PC on the network by typing “http://192.168.1.1” in the PC’s web browser address window, as shown in Figure 5-1.
Upon entering the address into the web browser, a password request page will pop up, as shown in Figure 5-2a. (Windows XP users will see a “Connect to
192.168.1.1” window, shown in Figure 5-2b.)
Leave the User Name field empty, and enter admin (the default password) in lowercase letters in the Password field. Then, click the OK button.
In this chapter, you will find brief descriptions of each of the utility’s tabs and its more important functions. More detailed explanations and instructions can be found by clicking each page’s Help button or on Linksys’s website at www.linksys.com. To clear any values you’ve entered on any page, click the

• SSID: The SSID is a unique name for your wireless network. It is case sensi­tive and must not exceed 32 characters. The default SSID is "linksys " but you should change this to a personal wireless network name. All wireless points in your network must use the same SSID. Verify that you are using the correct SSID and click the Apply button to set it.
• SSID Broadcast - Allows the SSID to be broadcast on your network. You may want to enable this function while configuring the Router, but make sure that you disable it when you are finished. With this enabled, someone could easily obtain the SSID information with site survey software and gain unauthorized access to your network. Click Enable to broadcast. Click Disable to increase network security and prevent the SSID from being seen on networked PCs.
• Channel Select the appropriate channel from the list provided to correspond with your network settings, between 1 and 11. (Higher channels can only be used outside of the United States and Canada.) All points in your wireless net­work must use the same channel in order to function correctly. Verify that the correct channel is selected and click the Apply button to set it.
• WEP (Mandatory/Disable). In order to utilize WEP encryption, select Enable. If you do not wish to utilize WEP encryption, make sure Disable is selected.
