EtherFast Cable/DSL Routers
Introduction
The Linksys EtherFast Cable/DSL Router
Congratulations on your purchase of a Linksys Instant Broadband EtherFast
Cable/DSL Router. The EtherFast Cable/DSL Router is the perfect option to
connect a small group of PCs to a high-speed Broadband Internet connection
or to an Ethernet backbone. Configurable as a DHCP server, the EtherFast
Cable/DSL Router acts as the only externally recognized Internet device on
your local area network (LAN). The Router serves as an Internet firewall,
protecting your network from being accessed by outside users. All incoming
data packets are monitored and filtered. The router can also be configured to
block internal users' access to the Internet.
Not only will all of your PCs now be able to enjoy your lightening-fast
Broadband Internet connection, they will also be able to share internal net-
work data. Add it all together and your small network will hum along faster
than you ever thought possible.
Features
• Connects to a Broadband modem or to an Ethernet backbone.
• Equipped with a 4-port 10/100 Switch (BEFSR41 only).
• Connects all of your PCs to the Internet with only one purchased IP address.
• Creates a firewall to protect your PCs from outside intruders.
• Configurable through any networked PC's web browser using Netscape or
Internet Explorer 4.0 or higher.
• The switch dramatically speeds up your gaming and multimedia connec-
tions.
• Can simultaneously act as both a DHCP Server on the LAN and a DHCP
Client on the WAN.
• Compatible with virtually all standard Internet applications.
• Administrators can block specific interior users' Internet access.
• DMZ Host option provides two-way communication between one PC and
your Internet services.

Getting to Know the 4-Port
EtherFast Cable/DSL Router
The 4-Port Router’s Rear Panel
The rear panel of the Router is where all of the Router’s connections are
made.
The 4-Port Router’s Ports
WAN The WAN (Wide Area Network) Port is where you
will connect your cable or DSL modem.
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 1. Uplinking to
another Router, switch or a hub is done by simply
running a cable from the Uplink Port to the other
device. If the Uplink port is being used, Port 1 will
not work.
Ports 1-4 These four LAN (Local Area Network) ports are
where you will connect networked devices, such as
PCs, print servers, remote hard drives, and any-
thing else you want to put on your network. If Port
1 is being used, the Uplink Port will not work.
Power The Power Port is where you will connect the
included AC Power adapter.

The 4-Port Router’s Front Panel LEDs
The LAN Indicators
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 con-
nected to a device through the corresponding port (1, 2, 3
or 4). If the LED is flickering, the Router is actively send-
ing 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 on
page 30 if you think there is a problem.
100 or 10/100 Orange. The 100 LED illuminates when a successful
100Mbps connection is made through the corresponding
port.

EtherFast Cable/DSL Routers
The WAN Indicators
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. It will turn
off upon successful completion of the diagnosis. If this
LED stays on for an abnormally long period of time, refer
to Troubleshooting on page 30.
The Reset Button*
Briefly pressing the Reset Button will refresh the Router’s con-
nections, 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. This should be done only if you are experienc-
ing 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.
* The Reset Button is located on the front of the 4-Port Router and on the rear of the One-Port
Router.

The One-Port Router’s Ports
WAN The WAN (Wide Area Network) Port is where you
will connect your cable or DSL modem.
LAN The LAN (Local Area Network) port is where you
will connect your Router to a network hub, switch,
or similar port.

Buttons & Switches
The Reset Button Information on the
Reset button can be
found on page 5.
The Crossover Switch The Crossover
Switch ( II X )
toggles the LAN
port between
crossover mode (X)
and straight-through
mode (II). If you are connecting the Router directly
to a computer or to an Uplink port, choose
crossover (X). For anything else, choose straight-
through (II).
The One-Port Router’s Front Panel LEDs
The LAN Indicators
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 con-
nected to a device through the LAN port. If the LED is
flickering, the Router is actively sending or receiving data
over the LAN port.

NNoottee::If you aren’t
sure whether to
choose crossover
or straight-through
on the crossover
switch, a good indicator is to
check the Link LED on the front
of the Router. If the Link light is
not illuminated after the router is
fully installed and configured, try
switching the crossover switch
over to the other option. If the
Link LED illuminates then, you
have made the correct choice.
