Features

Instant BroadbandTMSeries

Package Contents

• One Linksys EtherFast®Wireless Access Point + Cable/DSL Router with 4Port Switch

• One power adapter

• One Tech Helper CD-ROM

• Two Antennas

• One user guide and registration card

System Requirements

• One Broadband Internet connection using an External Cable or DSL

Modem (if sharing an Internet connection)

• One PC with an installed 10Mbps, 100Mbps, or 10/100 Mbps Ethernet card

(for initial setup)

• TCP/IP network protocol for each PC

• UTP network cable with RJ-45 connector

• Internet Explorer 4.0 (Minimum) or higher (5.0 Recommended), or

Netscape Navigator 4.0 (Minimum) or higher (4.7 Recommended)

Uplink The Uplink Port is where you can expand your net-

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

Power The Power Port is where you will connect the

included AC P ower adapter.

Antenna Jacks The Antenna Jacks are where you will connect the

included antennas.

The Reset Button

Briefly pressing the Reset Button will refresh the Router’s connections, potentially clearing any jammed links.

Pressing the Reset Button and holding it in for a few seconds will clear all of the Router’s data and restore the f actor y 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 the entire system(s).

If your router locks up, simply power it down for 3 to 5 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.

Link Green. The Link LED illuminates when a successful con-

nection is made between the Router and your Broadband device or network.

Act Green. The Act LED flickers when the Router is sending or

receiving data over the broadband port.

Diag Red. The Diag LED illuminates when the Router goes

through its self-diagnosis mode during boot-up and restart. It will turn off upon successful completion of the diagnosis. If this LED stays on for an abnormally long period of time, refer to the Troubleshooting section.

WLAN Link Green. The Link LED illuminates when the wireless option

is enabled. When the wireless option is disabled (through the Web-based utility), the LED is off.

Power Green. The Power LED illuminates when the Router is pow-

ered on.

Link/Act Green. The Link/Act LED serves two purposes. If the LED

is continuously illuminated, the Router is successfully connected to a device through the corresponding port (1, 2, 3 or 4). If the LED is flickering, the Router is actively sending or receiving data over that port.

Full/Col Green. The Full/Col LED also serves two purposes. If this

LED is continuously illuminated, the connection made through the corresponding port is successfully running in Full Duplex mode. If the LED is flickering, the connection is experiencing collisions. Infrequent collisions are normal. If this LED is flickering too often, there may be a problem with your connection. Check the Troubleshooting section if you think there is a problem.

100 Orange. The 100 LED illuminates when a successful

100Mbps connection is made through the corresponding port.

A dynamic IP address may change every time your computer connects to the network.

DHCP (Dynamic Host Configuration Protocol) DHCP is software that automatically assigns IP addresses to client stations logging onto a TCP/IP network. DHCP eliminates having to manually assign permanent IP addresses to every device on your network. DHCP software typically runs in servers and is also found in network devices such as Routers.

Connecting Your Hardware Together and Booting Up

Once you are sure that you have the above values on hand, you can begin the Installation and Setup of your Wireless Access Point + Cable/DSL Router.

1. Power everything down, including your PCs, your Cable or DSL modem and the Router.

2. Connect a Network cable from one of your PCs’ Ethernet ports to one of the LAN Ports on the back of the Router. 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.)

3. Connect the network cable from your Cable or DSL modem to the WAN port on the rear of the Router.

4. Connect the power-supply cable to the Power port on the rear of the Router, then plug the supplied AC power cable into a power outlet.

• The Power LED will illuminate green as soon as the power adapter is

connected.

• The Diag LED will illuminate red for a few seconds while the Router

goes through its internal diagnostic test. The LED will turn off when the self-test is complete.

5. Power on the Cable or DSL modem. Verify that the power is on by checking the Link LED in the WAN column on the front of the Router. The Link LED will be illuminated if the power is on and the modem is ready.

Connecting the Wireless Access Point + Cable/DSL Router to Your Network

Overview

Unlike a simple hub or switch, the setup of the Wireless Access Point + Cable/DSL Router consists of more than simply plugging ever ything together. Because the Router acts as a DHCP server, you will have to set some values within the Router, and also configure your networked PCs to accept the IP Addresses the Router chooses to assign them.

You will need the following values from your ISP in order to install the Wireless Access Point + Cable/DSL Router:

• Your broadband-configured PC’s f ixed Internet IP Address (if applicable)

• Your broadband-configured PC’s Computer Name and Workgroup Name

• Your Subnet Mask

• Your Default Gateway

• Your Primary DNS IP address

Whoever installed your broadband access should have left this information with you. If not, call your ISP and they will be able to supply you with it.

About Static & Dynamic IP Addresses

Static IP Addresses A static IP address is an IP address permanently assigned to computer in a TCP/IP network. Static IP addresses are usually assigned to networked devices, which are consistently accessed by multiple users, such as Server PCs, or print server. If you are using your Router to share your cable or DSL Internet connection, contact your ISP to see if they have assigned your home a static IP address. You will need that address during your Router’s configuration.

Dynamic IP AddressesA dynamic IP address is an IP address that is automatically assigned to a client station (computer, printer, etc.) in a TCP/IP network. Dynamic IP addresses are typically assigned by a DHCP server, which can be a computer on the network or another piece of hardware, such as the Router.

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 “email” or “pop3”, rather than “pop.mail.linksys.com”, you won’t be able to properly configure your Router until you determine the actual Internet addresses of your Web and e-mail connections.

4. Configure the following values.

Host Name & Domain Name These f ields allow you to supply a host and

domain name for the Router. Some ISPs require these names as identification. You may have to check with your ISP to see if your Broadband Internet service has been configured with a host and domain name. In most cases, leaving these fields blank will work.

LAN IP Address These values refer to your internal network settings.

Unless you have specific internal needs, there should be no reason to change these values. For the internal LAN, the default values are as follows.

• Private IP Address: 192.168.1.1

• Subnet Mask: 255.255.255.0

Wireless In this section, you can decide whether or not to use WEP

Encryption and conf igure the level of WEP Encryption. WEP Encryption is not necessary for the operation of your Router. For more information, see the section of this guide called Setting WEP

Encryption.

WAN IP Address These values refer to the outside network you connect to

every time you access your Broadband Internet connection. Most Broadband ISPs assign their clients with a different IP address each time they log on. If this is the case with your ISP, click Obtain an IP Address A utomatically and continue to step 5. If your ISP assigns you a fixed IP address, click Specify an IP Address and enter the address into the Subnet Mask, Default Gateway Address and DNS fields provided by the ISP.

6. Choose the DHCP tab.

7. Unless you already have a DHCP server on your internal network, choose Enable from the DHCP Server field. By choosing Enable, you will configure the Router to automatically assign IP addresses to each of your PCs. In the Number of DHCP Users box, enter the number of PCs you plan on networking to the Router. Don’t forget to change this number if, in the future, you add more PCs to your network. In most cases, these values will not have to be changed unless you have more than 50 computers on the network.

8. Click Apply, then click Continue.

9. Reset the power on the cable or DSL modem, then restart the computer so the computer can obtain the new Router information.

Your Wireless Access Point + Cable/DSL Router is now configured to

your network. If you would like, you may continue on to learn more

about the Router’s Web-based Utility.

NNoottee::

Make sure that a Network Card or adapter has been successfully installed into each PC you plan on configuring prior to continuing.

NNoottee::

You cannot have two DHCP servers running on one LAN at the same time. If you have an existing DHCP server on your LAN, you must decide which device will act as server. If you choose this Router, you must disable the DHCP capabilities of the other device, and vice versa. The device which is not the DHCP server must have a static IP address, which must be compatible with your existing network in order to be recognized.

PPPoE (Point-to-Point Protocol over Ethernet) Some DSL-based ISPs

use PPPoE to establish communications with an end-user. If you are using a DSL line, check with your ISP to see if they use PPPoE. If they do use PPPoE, you must enable it. If you do enable PPPoE, remember to remove any existing PPPoE applications already on any of your PCs. To enable PPPoE:

1. Click on the Enable option in the PPPoE section of the Setup screen.

2. Enter the User Name you use to log on to your Internet connection.

3. Enter your corresponding Password.

Connect on Demand (Only available if PPPoE is enabled) If you aren’t

actively using the Internet, you can configure your Router to cut your connection with your ISP after a certain period of time. If you have been disconnected due to inactivity, Connect on Demand enables your Router to automatically re-establish your connection as soon as you attempt to access the Internet again. If you wish to activate Connect on Demand, choose the Enable option.

Max Idle Time (Only available if PPPoE is enabled) Max Idle Time is the

number of minutes that passes before the Router drops your Internet connection, due to inactivity. For best connection reliability, the recommended settings are 0 or 9999. Otherwise, enter in the number of minutes you want to elapse before your Internet access disconnects.

Keep Alive Option (Only available if PPPoE is enabled) This option keeps

your PPPoE-enabled Internet access connected indefinitely, even when it sits idle. It keeps the connection alive by sending out a few data packets periodically, so your Internet service thinks that the connection is still active. To use this option, click on the box next to Keep Alive to select it.

5. When you have properly configured the Setup page, click Apply, then click Continue.
