Chapter 4: Configuring the PCsThe instructions in this chapter will help you conf igure each of your comput-
ers to be able to communicate with the Gateway.
To do this, you need to conf igure 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.
You will need to know which operating system your computer is running, such
as Windows 95, 98, Millennium, 2000, or XP.  One way to f ind out which oper-
ating system you have is by clicking the Startbutton and then going to the
Settingsoption. Then click Control Panel, and then double-click the System
icon. 
You may need to do this for each computer you are connecting to the Gateway.
The next few pages tell you, step by step, how to conf igure your network set-
tings based on the type of Windows operating system you are using. 
If your operating system is not referenced here, refer to your operating system
documentation.
Once youve conf igured your computers, continue to “Chapter 5: Conf iguring
the Gateway.”

							ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-ReadyChapter 5: Configuring the
GatewayIn this chapter, you will conf igure the Linksys ADSL Gateway to be able to
gain access to the Internet through your Internet Service Provider (ISP).  Yo u
will need the setup information provided by your ADSL ISP:
• Your ADSL line VPI and VCI
• Your ADSL encapsulation type and multiplexing
For PPPoAor PPPoEusers, you also need these values from your ISP:
• Your username and password
For RFC 1483users, you may need these values from your ISP:
• Your ADSL fixed Internet IP address 
• Your Subnet Mask
• Your Default Gateway
• Your primary DNS IP address
The above information should have been provided by your ADSL ISP. If not, contact
your ISP and they will be able to supply you with the correct settings. The instructions
from your ISP tell you how to set up your PC for Internet access.  Because you
are now using the Gateway to share Internet access among several computers,
you will use the setup information to conf igure the Gateway instead of your
PC.  You only need to conf igure the Gateway once using the f irst computer you
set up.

4. The Gateway supports f ive modes of Encapsulation: RFC 1483 Bridged,
RFC 1483 Routed, RFC2364 PPPoA, RFC2516 PPPoE, and Bridged Mode
Only. These modes are listed in the drop-down menu for the Encapsulation
setting. Each Setup screen and available features will differ depending on
what kind of connection mode you select. The instructions for RFC 1483
Bridged, RFC2516 PPPoE, and RFC2364 PPPoA are listed below; if the
instructions for your connection mode is not explained here, then proceed
to “Chapter 6: Using the Gateway’s Web Based Utility.”
A.RFC 1483 Bridged
This mode supports two types of WAN IP Addresses: Dynamic IP Address or
Static IP Address. Follow the directions for the type of WAN IP Address you
need to use.
Dynamic IP Address
If your ISP says that you are connecting through a dynamic IP address, fol-
low these steps:
1.Select Dynamic IP Addressas the WAN IP Address.  
2.Click the Applyand Continuebuttons to save the settings. 1. Open your web browser. (It is all right if you get an error message at this
point. Continue following these directions.) Enter http://192.168.1.1in the
web browser’s Address f ield. Press the Enterkey.
2. An Enter Network Password window, shown in Figure 5-3, will appear
(Windows XP users will see a Connect to 192.168.1.1 window, shown in
Figure 5-4). Enter adminin lowercase letters in the User Name f ield, and
enter adminin lowercase letters in the Password f ield (adminis the default
user name and password).  Then, click the OKbutton. 
3. The Gateway conf iguration screen will appear with the Setup tab selected.
Based on the setup instructions from your ISP, you may need to provide the
following information.
Host Nameand Domain NameThese f ields allow you to provide a host
name and domain name for the Gateway. These f ields are usually left blank.
If requested by your ISP, complete these two f ields.
Virtual Circuit ID (VPI and VCI)  These f ields consist of two items: VPI
(Virtual Path Identif ier) and VCI (Virtual Channel Identif ier).  Your ISP
will provide the correct settings for this f ield.

1483 Bridged,RFC 1483 Routed,RFC 2364 PPPoA, RFC2516 PPPoE,
and Bridged Mode Only. These modes can be selected from the drop-down
menu next to the Encapsulationsetting. Each Setup screen and available

The Setup screen is the f irst screen you see when you access the web-based
utility. If you have already installed and set up the Gateway, you have already
seen this screen and properly conf igured each of the values. 
• Host Name & Domain NameThese f ields allow you to supply a host and
domain name for the Gateway. Some ISPs require these names as identif i-
cation. You may have to check with your ISP to see if your broadband
Internet service has been conf igured with a host and domain name. In most
cases, leaving these f ields blank will work. 
• Firmware VersionThis entry shows the version and date of the f irmware
you are using. Future versions of the Gateway’s f irmware will be posted and
available for download on the Linksys website at www.linksys.com.
• Current TimeThe Gateway will try to reach an Internet timeserver and dis-
play the current time in this location. If a timesaver cannot be reached, this
will show the time elapsed since the Gateway was powered on.
• Time ZoneSet your local time zone in this f ield. If your region participates
in Daylight Savings Time (DST), check the box next to Daylight Savings
Time.
• LAN IP Address and Subnet MaskThe values for the Gateway’s IP
Address and Subnet Mask as seen on the internal LAN are shown here. The
default values are 192.168.1.1for the Device IP Address and 255.255.255.0
for the Subnet Mask.
• Virtual Circuit IDThese f ields consist of two items: VPI (Virtual Path
Identif ier) and VCI (Virtual Channel Identif ier). Your ISP will provide the
correct settings for these f ields. 
VPI Enter the number provided by your ISP. The number will be in the
range of 0 to 255.
VCIEnter the number provided by your ISP. The number will be in the
range of 0 to 65535.
