Wireless Access Point Router with 4-Port Switch

• One Windows 98 SE, Millennium, 2000, or XP PC equipped with:

• TCP/IP Protocol,

• Internet Explorer 4.0 or Netscape Navigator 4.7 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 Wide Area Network (WAN) that is 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, or the Wide Area Network (WAN), outside of your home or office.

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 WAN 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 LANs and WANs

BEFW11S4 VER 3 USER GUIDE_2nd.qxd 10/15/02 10:33 AM Page 1

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 WAN 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.

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 WAN side. In this User Guide, you’ll see references to the “WAN IP address” and the “LAN IP address.”

Since the Router has firewall security (NAT), only the Router’s WAN IP address can be seen from the Internet.

However, even the WAN 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”.

Instant WirelessTMSeries

BEFW11S4 VER 3 USER GUIDE_2nd.qxd 10/15/02 10:33 AM Page 2

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 WAN 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.

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.

The Router’s rear panel (as shown in Figure 1-1) is where all of its connections are made.

WA N The WAN (Wide Area Network) Port is where you will con-

nect your cable or DSL modem with an Ethernet cable. Your

modem connection will not work from any other port.

Ports 1-4 These four LAN (Local Area Network) ports are where you

will connect networked devices, such as PCs, print servers, and any other Ethernet devices you want to put on your network. If Port 4 is being used, the Uplink Port will not work.

Uplink The Uplink Port is where you can expand your network by

connecting to another switch or hub. Uplinking to another switch or a hub is done by simply running a cable from the Uplink Port to the other device. The Uplink Port is shared with Port 4. If the Uplink port is being used, Port 4 will not work.

Power The Power Port is where you will connect the included AC

Power adapter.

Antenna Jacks The Antenna Jacks are where the included antennas are con-

nected.

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.

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. (LAN Port 4 will become inactive if you use the Uplink port.)

In addition to accessing the Router through an Ethernet connection, a wireless connec-

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 Access Point Router with 4-Port Switch 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.

You

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.

Chapter 4: Configuring the Router

This chapter will show you how to conf igure the Router to function in your network and gain access to the Internet through your Internet Service Provider (ISP). Detailed description of the Router’s Web-based Utility can be found in the Chapter 5: Using the Router’s Web-Based Utility. Your ISP may require the use of a Host Name and Domain Name. Further, you will set the WAN Configuration Type on the Router’s Setup tab from the information given by your ISP. You will need this setup information from your ISP. If you do not have this information, please contact your ISP before proceeding.

The instructions from your ISP tell you how to set up your PC for Internet access. Since you are now using the Router to share Internet access among several computers, you will use this setup information for Router configuration.

1. Open your web browser, and enter 192.168.1.1 into the web browser’s Address field, as shown in Figure 4-1. Then, press the Enter key.

2. An Enter Network Password window, shown in Figure 4-2a, will appear. (Windows XP users will see a Connect to 192.168.1.1 window, shown in Figure 4-2b.) Leave the User Name field empty, and enter admin (the default password) in lowercase letters in the Password field. Then, click the OK button.

3. If required by your ISP, enter the Router’s Host Name and Domain Name in the appropriate fields on the Setup tab. (This is usually required by cable ISPs.)

4. To configure the Router for your wireless network, verify that the Setup tab’s Wireless fields (shown in Figure 4-3) are completed as follows:

Enable/Disable: Selecting the Enable radio button will enable the Router’s wireless feature. Wireless functions will not be available unless enabled.

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.

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 for your network from the list provided. All wireless points in your network must use the same channel in order to function properly.

Do not change the WEP setting from the default, “Disabled”, without first referring to the Wireless Security sections of the User Guide or Setup Wizard CD-ROM for advanced features and settings.

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

Cancel button. To apply any settings you’ve altered on any page, click the Apply button.

• 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.

• WEP Key Setting When WEP Encryption is Enabled, press this button to modify the WEP Key Settings.

For further details on configuring Wireless Security, using WEP, refer to Appendix C: Configuring Wireless Security.

These types are selected from the drop-down menu beside WAN Connection Type. The Setup tab and available features will differ depending on what kind of connection type you select. Each option is described on the following pages.

Obtain an IP Automatically

If your ISP says that you are connecting through a dynamic IP address (or DHCP), select this option from the drop-down menu (as shown in Figure 5-3). Now, the Router will accept the dynamic IP addresses assigned by your ISP when connecting to the Internet.
