Linksys Cable/DSL Firewall Router Quick Start Manual

You may have different computers than what are pictured here,but the setup is sim-

ilar. The Router lets you share your fast cable or DSL connection among several com-

puters in your home or business. This is called a Local Area Network or LAN.

This Fast Start guide gives you the “big picture”of what you need to set up a basic

home or business network. The next three sections explain how you will set up and

configure your equipment to enable shared high-speed access to the Internet.

Step 1: Connect the Router

Connect the Router to your cable or DSL modem and to your notebook or desktop

PCs.

Step 2: Configure the PCs

Configure your notebook or desktop PCs to be able to communicate with the Router.

Step 3: Configure the Router

Do the basics to get the Router to work with your cable or DSL modem and your ISP’s

settings.

Congratulations! Thank you for choosing the Linksys EtherFast

®

Cable/DSL Firewall

Router. The Router allows you to set up a home or small business networkto share

your high-speed Internet connection.

Why do I need a network? Networks are useful for sharing computer resources

such as printers,files, and CD-ROM drives. Networks are even used for playing mul-

tiplayer video games. So,not only are networks useful in homes and businesses, but

they can also be used for fun.

The most remarkable thing the Router does is to let you share your high-speed cable

or DSL connection to the Internet. The Router connects your LAN (Local Area

Network) to a WAN (Wide Area Network). The Internet is a network that,being glob-

al,covers the widest area of all! All PCs connected to the Router can share this con-

nection.

How is this accomplished?You will be setting up a simple LAN. Your PCs are con-

nected via Ethernet cable from an Ethernet adapter (in or attached to your PC) to one

of the Router’s LAN ports. The term “Ethernet” is used to refer to your network

accessories, such as cables and adapters, because Ethernet refers to the type of

network you are setting up.

Then the Router is connected to your cable or DSL modem. The Router makes it

seem as if each PC is connected directly to the Internet. Several PCs can then use

one Internet connection simultaneously.

Use the Linksys Router Setup Wizard CD-ROM or the instructions in this Fast

Start to help you connect the Router, configure your PCs,and configure the Router.

These instructions will get you up and running quickly using the most basic settings.

Once you have access to the Internet, you can get advanced configuration informa-

tion (for gaming, VPNs, web hosting, etc.) by visiting our website at

support.linksys.com

or by reading the User Guide on the Setup Wizard CD-ROM.

B. Using the Ethernet cable that came with your cable

or DSL modem, connect the LAN or Ethernet port of

the cable or DSL modem to the WAN port of the

Router.

C. Connect an Ethernet cable to your PC’s Ethernet adapter. Connect the other end of

the cable to one of the LAN ports on the back of the Router. Repeat this process for

every PC you wish to connect to the Router.

Note: If your PC’s Ethernet adapter is not set up, please refer to the Ethernet

adapter’s user guide for more information.

Note: For ease of installation, start with LAN Port 4/DMZ, then Port 3, then Port 2,

and finally Port 1.

If you are connecting more than four PCs to the Router,you will need to connect

a hub or switch to Port 1, 2, 3, or 4/DMZ of the Router. Please refer to the User

Guide located on the Setup Wizard CD-ROM.

D. Connect the power adapter to the Router. Connect

the power adapter to the electrical outlet. Turn on

the cable or DSL modem. Then turn on the first PC

you wish to use to configure the Router.

Proceed to Step 2: Configure the PCs on the next page.

In Step 1, you will connect the Router to your cable or DSL modem and to the com-

puters in your home or business.

First, make sure that all devices you’ll be working with are powered down, includ-

ing your PCs, modem, and the Router.

A. If you haven’t already done so,connect your cable or DSL modem to its proper

connection—the coaxial jack for cable (Figure A1), or the phone jack for DSL

(Figure A2). (Follow the instructions from your cable or DSL modem’s installation

guide.)

In Step 2,you will configure each of your computers to be able to communicate with
the Router.

To do this, you need to configure your PC’s network settings to obtain an IP (or
TCP/IP) address automatically (called DHCP). Computers use IP addresses to com­municate with each other across a network or the Internet.

Find out which operating system your computer is running,such as Windows 95, 98,
Millennium, NT 4.0, 2000, or XP.

You will need to know which operating system your computer is running. You can
find out by clicking the Start button and then going to the Settings option. Then
click Control Panel, and then double-click the System icon. If your Start menu
doesn’t have a Settings option,you’re running Windows XP. Click the Cancel button
when done.

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 settings

based on the type of Windows operating system you are using. Once you've config­ured your computers,continue to Step 3: Configure the Router.

A. Go to the Network screen by clicking the

Startbutton. Click Settings and then Control
Panel. From there,double-click the Network

icon.

B. On the Configuration tab, select the TCP/IP

line for the applicable Ethernet adapter*. If

the word TCP/IP appears by itself,select that
line.** Click the Propertiesbutton.

C. Click the IP Address tab. Select Obtain an IP

address automatically.

D. Now click the Gateway tab to ensure that the

Installed Gateway field is left blank. Click the

OK button.

E. Click the OK button again. Windows may ask

you for the original Windows installation disk
or additional files. Supply them by pointing to
the correct file location, e.g., D:\win98,
D:\win9x, c:\windows\options\cabs, etc. (if
“D” is the letter of your CD-ROM drive).

F. Windows may ask you to restart your PC.

Click the Yes button. If Windows does not ask
you to restart,restart your computer anyway.

*Note:Do not choose a TCP/IP entry whose name mentions DUN, PPPoE, VPN,or
AOL.

**Note: If there is no TCP/IP line listed,refer to the User Guide found on the Setup
Wizard CD-ROM or your Ethernet adapter’s user guide to install TCP/IP now.

A. Go to the Network screen by clicking the Start

button. Click Settings and then Control

Panel. From there,double-click the Network
and Dial-up Connections icon.

B. Select the Local Area Connection icon for

the applicable Ethernet adapter (usually it is
the first Local Area Connection listed). Double­click the Local Area Connection. Click the

Properties button.

C. Select Internet Protocol (TCP/IP), and click

the Propertiesbutton.

D. Select Obtain an IP address automatically.

Once the new window appears, click the OK
button. Click the OK button again to complete
the PC configuration.

E. Restart your computer.

The following instructions assume you are run­ning Windows XP with the default interface. If you
are using the Classic interface (where the icons
and menus look like previous Windows versions),
please follow the instructions for Windows 2000.

A. Click to the Network screen by clicking the

Start button and then Control Panel. From
there, click the Network and Internet
Connections icon and then the Network
Connections icon.

B. Select the Local Area Connection icon for

the applicable Ethernet adapter (usually it is
the first Local Area Connection listed).
Double-click the Local Area Connection.
Click the Properties button.

C. Select Internet Protocol (TCP/IP), and click

the Propertiesbutton.

D. Select Obtain an IP address automatically.

Once the new window appears, click the OK
button. Click the OK button again (or the
Close button if any settings were changed) to
complete the PC configuration.

E. Restart your computer.

• My

WAN Link

LED isn’t lit. What should I check?

- Check that the cable you are using between your cable or DSL modem and

the Router is the same cable that came with your modem. Depending on

the type of connection your modem uses,you may need either a “straight-

through” or “crossover” Ethernet cable (the “straight-through” type is

more common).

• Some of the lights on the front of the Router don’t light up when I plug in a PC.

- Only the

Link/Act

LED is required for a connection to work correctly.

3. I cannot get onto the Internet, nor can I access the Router’s Setup page.

What should I check?

A. First check that the cable or DSL modem and computers are properly connected

to the Router. See Question #2 for how to verify that the connections are good.

B. Then, check that you have properly configured your PCs to communicate with the

Router. Below you will find instructions for the various versions of Windows.

- Windows 95, 98,or ME

• Click the Start menu, and then click Run. After the Run window appears,

enter winipcfg in the Open field, and then click the OK button.

• When the IP Configuration window appears, click the gray box with a black

arrow pointing down.

• A list of adapters will appear. Select the adapter that you use to connect

to the Internet. These items should not contain “PPP”, “VPN”, “AOL”, or

“Dial-Up adapter” as part of the entry.

• The IP Address field should show an IP address of 192.168.1.100 or

192.168.1.xxx, with “xxx” being any number greater than 100.

If your IP address is not in that range,hold the reset button on the front of

the Router for more than 30 seconds. This will cause your Router to be set

192.168.1.xxx, with “xxx” being any number greater than 100.

If your IP address is not in that range,hold the reset button on the front of

the Router for more than 30 seconds. This will cause your Router to be set

to factory default,so you will need to re-configure the Router's Setup page.

After re-configuring the Setup page,restart the computer.

C. Now you will configure some settings in Windows.

- Go to your desktop and double-click My Computer, and then double-click

Control Panel (Windows XP users using the default interface,click Start, and

then select Control Panel).

- Click the OKbutton and the Apply button (the Apply button will be grayed out if

you did not have to make any changes). Then click the OKbutton again.

- Exit the Control Panel, and restart your computer.

4. When I click on the icon to access the Internet, and enter the user name

and password that my ISP gave me,I cannot connect to the Internet. What

is wrong?

This means that you’re using the software given to you by your ISP. Please use

Internet Explorer or Netscape Navigator,which is located on your desktop (located

on the Start Menu in Windows XP).

5. When I use Internet Explorer, a box pops up prompting me to dial up a

connection. How can I disable that?

A. Go to your desktop and double-click My Computer, and then double-click

Control Panel (Windows XP users using the default interface,click Start, and

then select Control Panel).

B. When the Control Panel window pops up,double-click the Internet Options icon

D. Check Never Dial Up a Connection.

E. Click the Apply button.

F. Click the OK button.

6. When I click the

Apply

button on the setup page of the Router, I get

prompted for my user name and password again. I try to enter

admin

for

the password, but I get a red screen after 3 tries. How do I fix this?

A. Go to your desktop, and double-click the Internet Explorer icon (located on the

Start Menu for Windows XP).

B. When Internet Explorer appears, enter http://192.168.1.1/Passwd.htm in the

Address field,and click Go.

C. The Enter Network Password screen will appear (Windows XP users will see a

Connect to 192.168.1.1 window).

D. Leave the user name field blank. Type adminin the Password field. Then click

the OK button.

E. You should now be at the Password page of the Router’s utility.

F. Select the first field that displays a series of asterisks, *********** (Windows XP

users will see a series of bullets),and delete each *. (Make sure this field is left

blank.)

G. Select the second field that displays a series of asterisks, *********** (Windows

XP users will see a series of bullets), and delete each *. (Make sure this field is

left blank.)

H. Click the Apply button and then the Continue button.

I. Now the Router does not have a password.

You should now be able to click the Apply button on the Setup page. Don’t forget to

add a password later.

7. I tried the suggestions above and still cannot get access to the Internet

from my Router.What can I do?
